In order to fully comprehend its therapeutic mode of action, homeopathy might require both ‘local’ bio-molecular mechanisms, such as memory of water and ‘non-local’ macro-entanglement, such as patient–practitioner–remedy (PPR) descriptions.

Introduction

Despite increasingly sterile debates over ‘whether’ homeopathy works,¹ the ‘how’ and ‘why’ have yet to be seriously addressed by science. One need not look far to see why.

Formerly a successful allergy researcher,² Jacques Benveniste spent the last 20 years of his life out of the scientific mainstream because of his fascination with the ‘Memory of Water’.³ Despite democratic appearances, when it comes to dealing with what it considers ‘heretical’ (eg, homeopathy), science can be as narrow-minded, unforgiving, and vicious as any inquisition. Disregarding the burning stakes of peer opprobrium however, some are seeking answers to the question of how homeopathy might be possible.

Two types of hypothetical ‘mechanism’ are under consideration. Labelled ‘local’ and ‘non-local’, they depend, respectively, on conventional scientific positivism,⁴ or appeal to generalised quantum theoretical concepts of complementarity and entanglement.⁵ Local hypotheses envisage homeopathic remedies behaving in a way similar to any other medicine, ie, ‘pharmacologically’. The problem is that most homeopathic remedies are diluted out of molecular existence. In order therefore to comply with the causal principles of positivist science, a mechanism has to be envisaged by which some kind of information transfer (usually thought of as electromagnetic) can occur to a molecular substrate (eg, water), via homeopathy’s unique method of remedy production.⁶ Involving successive iterations of dilution followed by violent agitation collectively known as succussion, it is this information transfer to the solvent which has been called the Memory of Water (MoW).

Non-local hypotheses,⁷ are concerned less with the remedy per se, proposing generalised forms of quantum entanglement as the basis for homeopathy’s efficacy. They suggest instantaneous, acausal correlations are somehow established between various combinations of patient, practitioner, and remedy, ultimately leading to an observed change in the patient’s state of health. These ideas are in their infancy and even more controversial than MoW: indeed, to many the idea that quantum theory might be applicable in our macroscopic domain is anathema. The received conventional wisdom is that non-deterministic quantum theory describes the world of sub-atomic particles, atoms and molecules, while deterministic Newtonian (classical) and Einsteinian (relativistic) theories are sufficient for the macroscopic world of material objects. Non-local hypotheses however, have the advantage of being generalisable outside homeopathy to other healing disciplines.

The purpose of this paper is to review the two types of descriptions of homeopathy’s effects. Then, viewing these different approaches as complementary, not contradictory, and realising that some local explanations are also ‘tarred’ with the brush of entanglement (albeit at the molecular level), to consider how a more complete picture of the homeopathic process might be possible, ultimately leading to new experimental tests.

Locality, non-locality, and philosophy

Most, but by no means all, of science is based on a set of assumptions about the universe collectively known as Local Reality.⁸ This may be summed up as follows:

• The universe is real and things in it exist whether we observe them or not.

• It is legitimate to draw general conclusions and predictions from the outcome of consistent experiments and observations.

• No signal can travel faster than light.

This is very much a ‘common sense’ view of the universe as (a) it defines ‘reality’ as something obviously ‘out there’ separate and independent of us and (b) it is ‘local’ because parts of the universe out of speed of light contact cannot possibly be in communication. For most of the time, this assumption of Local Reality ‘works’: it is an accurate descriptive model of how most things in the universe interact. However, recent quantum physics experiments on photons, electrons, atoms, and even molecules demonstrate beyond doubt that particle interactions result in non-local correlations.⁸ This means that although there is no signal transfer in the classical sense between these particles, nevertheless, they can be instantaneously ‘connected’ over vast distances and across time itself, a phenomenon known as quantum entanglement.⁹ It is as if at a deep level, everything in the universe is instantaneously linked together in a vast holistic matter-energy network of interacting fields which transcends ordinary concepts of space and time. And we, composed of trillions of particles are an inseparable part of it: far from what reason seems to tell us.

The three Local Reality points above have been expanded into seven propositions, which are essentially ‘articles of faith’,¹⁰:

(1) The universe is consistent over all space and all time.

(2) The universe is understandable, ie, predictable.

(3) What is valid here is valid elsewhere.

(4) The universe is material and not spiritual.

(5) Everything that is physical is observable.

(6) The universe can be described and ascertained mathematically.

(7) Experiment validates theory.

This ‘catechism’ arises out of science’s primarily inductive logical structure. Philosophers have described two types of reasoning called deductive and inductive logic. In the former, one can draw true conclusions from true starting premises. For example, consider the following statements:

• All swans are white.

• The creature in front of us is a swan.

Ergo, from these two premises, we can conclude (especially if we choose not to look) that:

• The creature is white.

With inductive logic however, we move from the particular to the general from premises about objects we have examined, towards conclusions about objects that we have not yet examined. Thus:

• Every swan I have ever seen has been white; Ergo….

• The next swan I see will be white.

What this simple example demonstrates is that many of our beliefs are based on extrapolations from observed (past or present) events to situations which are unknown, unobserved, or in the future. It was the 18th century philosopher Hume who pointed out that inductive reasoning is based on custom or habit, and in so far as it predicts the future will resemble the past, cannot actually ‘prove’ anything, for instance the impossibility of a swan being black. Hume also pointed out that the principle of induction cannot itself be proven by induction. The word ‘proof’, in fact, should be applied strictly only when reasoning deductively, as in mathematics. As most science is rooted in inductive logic, if follows that it too is predictive and actually incapable of proving or disproving anything.

In addition, Peirce drew attention to abduction which refers to the creative process prior to induction and deduction, by which scientists arrive at their initial hypotheses in the first place.¹¹ It involves ordering disparate pieces of information into a first hypothetical structure and may be likened to pattern recognition: something humans seem particularly good at. Reductionist scientific theories generally overlook or are incapable of considering the process of abduction.

So what tends to happen in practice is that the more often a premise’s predictions turn out to are fulfilled, the more it is taken as ‘proof’ that the premise must be true. Eventually, the ‘truth’ of the premise becomes ingrained: it changes from ‘Every swan I have ever seen has been white’ to ‘All swans are white.’ From that moment, black swans are ‘impossible’.

Most people assume that science starts from secure reproducible observations out of which ‘facts’ about the world are distilled, an ideal enshrined in logical positivism. Its core beliefs are that scientific questions can be answered completely objectively; that experiments allow scientists to compare theory directly with facts; and that science is a sure route to ‘truth’. In this respect, it is scientifically established ‘evidence’ that is now supposed to provide the only basis for the ‘facts’ on which medical decisions are to be based, regardless of practitioners’ empirical ‘hands on’ experience and intuition.^{[12] and [13]}

However, since the second half of the 20th century, logical positivism has been under sustained attack as being too simplistic from Post-Modernist philosophies of science.¹⁴ There is no such thing as unbiased observation free of any sociological or cultural conditioning, even in science and even under the most stringent experimental circumstances. Therefore, our acceptance or rejection of ‘evidence’ is also open to serious question. Our tendency is to reject evidence which does not fit with currently-held theory. Consequently, positive results from even the highest standard scientific trials are rejected by those who will not accept homeopathy’s claim that remedies diluted out of molecular existence might have any effect. For black swans, read homeopathy.

Kant, in the 18th century, pointed out that observation depends on our individual senses, assumptions, and background beliefs.¹⁵ He suggested that our picture of the world is structured by a combination of sensory data (‘phenomena’) and fundamental concepts of reason, eg, ‘causation’, that are culturally ‘hardwired’ into our minds. Consequently, we cannot know anything about how the world ‘really is’. Recent interpretations of quantum theory¹⁶ take this idea further by suggesting there is no world ‘out there’ separate from and independent of our observation of it. Or even more starkly, information is all there is.

Local hypotheses and the memory of water

Benveniste did not coin the phrase ‘Memory of Water’ (MoW), as research into solvent effects dates back to the 1960s. However, his research was highlighted by Nature in 1988,³ and subsequent failed attempts to repeat it.¹⁷ A multi-centre European trial involved modifications to Benveniste’s original method (eg, the use potentised histamine instead of anti-IgE), and was statistically significant only on pooling the results from all the laboratories involved.¹⁸ Though still controversial, MoW is based on the same conventional scientific notions of atoms and molecules that inform chemistry, biochemistry and molecular biology. I shall deal with this on a general basis only as excellent and more detailed contributions will be found in this issue from Anick, Chaplin, Elia, Rey, Rao and others.

As Albert Szent-Gyorgyi pointed out, ‘Water is the mater and the matrix, the mother and the medium of life.’⁴ Without water, life as we know it would be impossible. Yet, water is more complex than the simple chemical formula H₂O suggests. Oxygen, at the top of Group 16 in the Periodic Table, is a gas while the other members of this column (sulphur, selenium, and tellurium) are solids. With the di-hydrides of these elements we notice another major difference. H₂S, H₂Se, and H₂Te, are highly toxic, inflammable, evil-smelling gases, while H₂O is a clear, tasteless, odourless, life-giving and sustaining liquid (see Table 1). This is due to electrical forces originating within the oxygen atom. Apart from establishing the main chemical bonds between each oxygen and two hydrogen atoms, they also give rise to extra more complex forms of weak bonding (hydrogen bonds and even weaker van de Waal’s interactions). At room temperature these loosely bind individual water molecules into large rapidly-changing (in the order of pico-seconds) dynamic ‘structures’ (Fig. 1).⁴ These, in turn influence interactions between chemical and biochemical entities.

The green-to-pink envelope represents the distribution of electrical charge within the molecule, biased towards the oxygen atom. In (b), we see the more classical ‘ball and stick’ model. The red ball represents the oxygen atom while the white balls represent hydrogen atoms, the white spheres without inscribed ‘H’s’ are hydrogen-bonded hydrogen atoms from a neighbouring (unseen) water molecule: the short white ‘sticks’ between the balls represent static chemical bonds between hydrogen and oxygen atoms. In (c), we see a representation of how water molecules might loosely bind to each other via hydrogen bonding (the longer white sticks) to form a coherent but short-term structure.²⁰

Adopting a theatrical metaphor, if nucleic acids, proteins, carbohydrates, lipids and hormones, etc are the principal ‘actors’ in the unfolding biochemical ‘drama’ that is life at the molecular level, then water provides the stage, set, theatre, and direction. From this perspective, it could be that conventional bio-medicine places too much emphasis on bio-molecules at the expense of the solvent in which they perform. Because of individual patterns of electrically charged and neutral atomic constituents, each type of bio-molecule will have associated with it an ever-changing ‘halo’ of loosely bound and interconnected water molecules.¹⁹ At the charged sites on each bio-molecule, water molecules will congregate, while few water molecules gather at the neutral sites. Thus, electric fields generated by bio-molecules will be modified and modulated by their surrounding ever-changing but coherent ‘halo’ of water molecules, and this could be transmitted extremely rapidly partly via water’s rapidly switching network of interconnecting hydrogen bonds, throughout the whole solvent and received by other bio-molecules.

There is much about water yet to be discovered, so that even if scientific attention were to shift away from bio-molecules to their aqueous medium, the experimental and theoretical problems would be enormous. For example, within a single cell, there are huge differences in the water content and properties of its various parts, from the jelly-like consistency of the cytoplasm, to the more fluid content of vacuoles. Modelling such diversity is likely to be a computational nightmare.¹⁹ However, modelling water itself shows that its molecules can form short-term coherent ‘structures’, whose life is of the order of pico-seconds (10⁻¹² s) similar to icosahedra (Fig. 2) around central cavities that may contain, or may have once contained solute species.²⁰ From here, it is not hard to imagine that such dynamic aqueous ‘structures’ could be the bearers of a ‘memory’ of things once dissolved but now dissolved out.

Using chemical terminology, MoW might be considered a supra-molecular phenomenon involving many water molecules. This means that MoW would be an emergent dynamic property of bulk liquid water (ie, involving many trillions of water molecules: in other words, the whole is more than the sum of its individual molecular parts). This would defy explanation in terms of the usual ideas of static chemical bonds and purely additive behaviour between individual water molecules alone. Certainly water molecules’ ability to dynamically switch hydrogen bonding to each other would be of crucial importance here, as are other weak intermolecular interactions (eg, van de Waal’s forces). Chaplin gives a compelling description of this behaviour on his website.²⁰

Sceptics often quote the laws of thermodynamics as grounds for the impossibility of MoW. They are correct if one attempts to understand MoW effects in terms of a system at thermodynamic equilibrium. However, the principles of equilibrium thermodynamics cannot explain what happens to a system far from equilibrium, especially at what are called critical points. These are temperatures and pressures where, for example, a gas is just about to liquefy. In this critical state, a gas is much denser than under normal equilibrium conditions. It remains as a single phase system but is exquisitely sensitive to even the slightest externally-induced fluctuations, which can cause separation into gaseous and liquid phases.

Now, highly metastable far-from-equilibrium critical states develop patterns of chaos and self-similarity better described by Prigogine’s seminal work on non-equilibrium thermodynamics than by classical thermodynamics. Such states occur during the chemical reactions within living cells.²¹ Hankey has presented a plausible hypothesis that might help explain MoW effects in terms of such critical points acting as local dynamic attractors of a system. This led him to a novel model of the life force, capable of predicting the correct relationship between it and cure in several systems of complementary medicine, including homeopathy.²²

The key to such models is the recognition that fluctuating instabilities at critical points necessarily exist in quantum form, and require quantum descriptions to predict their effects. It turns out these quantised instability fluctuations can serve the highly unusual function of ‘lifting’ quantum properties out of their confinement within the microscopic domain of atoms and molecules, and into our macroscopic world of bulk material properties. Under these exceptional circumstances, macroscopic systems may exhibit similar properties to microscopic quantum systems, such as coherence, and this has been observed and recognised with low-temperature superconductors and super-fluids.²³

Interestingly, support for the MoW concept has come recently from the field of materials science.²⁴ Using a large interdisciplinary research base, Roy et al examined the structures of many non-crystalline, inorganic, covalently-bonded condensed liquid phases, including liquid water. They predicted that at ambient conditions, typical samples of water likely contain many dynamic water structures. These consist of a statistical mixture of single water molecules (monomers) and different-sized water molecule clusters (oligomers), the largest consisting of several hundred H₂O units. From this, they arrived at the important conclusion that it is solution structure not solution composition which is important in determining the plausibility of MoW effects. From the materials science perspective, although an ultra-diluted solution (where the solution is diluted out of existence) up having the same composition as the original solvent water, their structures could be entirely different.

In quantum physics there is also support for the MoW concept. For example, Smith has for many years argued for electromagnetic coherence and memory effects in water.²⁵ While Del Guidici et al predicted that given a large enough number of water molecules (of the order of 10¹⁵–10¹⁷, an amount visible to the naked eye), the sum total of all the hydrogen-bonded interactions between the water molecules could, under the right circumstances, lead to a dynamic, rapidly fluctuating yet correlated state where they all resonate together, spontaneously organising themselves into so-called ‘coherent domains’.²⁶ Del Guidice et al went on to show that such dynamic and correlated ‘coherent domains’ could not only be triggered by homeopathy’s potentisation process (ie, serial dilution and strong agitation), but that they would survive removal of all trace of the original dissolved substance. In other words, a possible theoretical mechanism for MoW effects exists and fits neatly with Roy et al‘s conclusions on the importance of solution structure over composition.

Critics of MoW incorrectly assume that that the physical and chemical properties of a solution are not dependent on its history. Samal and Geckler have reported such historical dependence in a series of experiments, using solutions of a wide variety of substances including common salt, starch and DNA at different non-homeopathic dilutions.²⁷ This work demonstrated that molecules of a substance aggregate on dilution rather than getting further apart as common sense might suggest. Also, the size of these molecular aggregates relates to the starting concentrations of the original solute: in other words, they show an historical dependence.

In a completely different field, Rey obtained thermoluminescence data from highly agitated ultra-high dilutions of lithium and sodium chloride, suggesting reproducible differences from pure water diluted with itself.^28a However, replication of this study by van Wijk though to some extent reproducing Rey’s original findings, failed to show statistical significance until the solutions had been standing for several weeks prior to obtaining thermoluminescence data.^28b This could suggest the possibility of the data being artefactual as a result of the D₂O used in the experiments leaching traces of silica from the glassware. Such silica leaching artefacts have previously been noted in high-dilution experiments.²⁹ However, Elia has obtained thermodynamic and conductivity data which strongly suggest that the process of sequential dilution and succussion is capable of permanently modifying many of the structural features of water. Elia concludes that, thermodynamically speaking, such systems are far from equilibrium and capable of self-organising themselves as a result of only small perturbations, confirming Roy et al‘s conclusions.³⁰

It is perhaps sufficient to say that an explanation for the efficacy of highly diluted homeopathic remedies within the ‘local’ paradigm of the molecular sciences, though difficult is not as improbable as homeopathy’s critics claim.

Non-local hypotheses and macro-entanglement

In which case, why bother with quantum theoretical non-local hypotheses? Simply because deterministic local hypotheses could have the effect of confining attention to the medicine as the sole therapeutic agent, at the expense of the perhaps equally important contextual dynamics of the patient–practitioner relationship. Having said that, it is worth pointing out that some local explanations of homeopathy’s effects, eg Del Guidice et al and their concept of ‘coherent domains’ of water molecules moving in some correlated fashion, are strongly suggestive of entanglement at the molecular level.²⁶ Consequently, it is worth remembering that the sections in this paper headed ‘local hypotheses’ and ‘non-local hypotheses’ are not intended to suggest that they are mutually contradictory. On the contrary, it is far more likely that both will be required in order to fully explain homeopathy’s effectiveness: a prediction consistent with the complementary nature of quantum theory.

Biomedicine takes little account of patient individuality or therapeutic context. From this point of view, perhaps the time has come for the discussion of homeopathy (indeed of all therapeutic modalities) to move out of the narrow confines of deterministic biomedicine. Theoretical models need to be developed that more fully encompass and make sense of its experiences, while at the same time not losing sight of the ‘local’ importance of the medicine. But why invoke non-local explanations based in something as seemingly exotic as quantum theory? How could it possibly apply to ‘macroscopic’ objects, especially people? And does not that play right into the hands of sceptics who accuse homeopaths of clutching at ill-understood scientific straws so that they can justify the patently unjustifiable? It is probably worth noting that homeopathy’s sceptics do not have a monopoly on the understanding or indeed misunderstanding of quantum theory. As the Nobel-pzrize winning physicist Richard Feynman once famously remarked, ‘Anyone who thinks they have understood quantum theory has probably got it wrong!’³¹ For example, a common assumption is that quantum theory and its implications apply only within the confines of particle physics, not in our macroscopic world.

It is true quantum theory’s algebraic language is dominated by an incredibly small number called Planck’s constant (6.626×10⁻³⁴ J s), commensurate with observations and measurements of events occurring at the sub-atomic through to the molecular domains. However, it turns out that one of the strangest outcomes of quantum theory—the notion of entanglement—need not be size-limited.³² Entanglement is said to occur when the parts of a system are so holistically matched, measurement of one part of the system instantaneously (ie, not limited by the speed of light) provides information about its other parts, regardless of their separation in space and time.⁹ What is important is whether the elements of the system are correlated (ie, act as one coherent indivisible whole), and whether such a system’s processes can be described using a ‘non-commuting algebra of complementary observables’.³³ This means when two separate operations of observation are performed sequentially, the overall result depends on the sequence and what is being measured. This is readily understood when considering a set of operations involved in, say, cooking. Here the operational sequence is paramount, for in a different order, instead of a tasty meal, one is likely to end up with any number of disagreeable and inedible offerings. Expanding on this concept leads to another key idea from quantum theory: complementarity.³¹

Thus, a single explanation or model might not adequately explain all the different observations that can be made on a quantum system. For example, in order to explain how electrons are diffracted when they strike the atoms in a crystal lattice, it is necessary to assume that each electron behaves as a wave. However, when considering the photoelectric effect and electrons being expelled from a solid when struck by photons of the right energy, it is necessary to assume that the electrons and the photons are behaving as particles. This results in the well-known apparent contradiction of particle-wave duality. The point is, in order to fully explain quantum phenomena it is necessary to have two different but complementary concepts. It is almost as if the answer one obtains on performing the two observations depends entirely on how the (experimental) question is asked; and both are necessary in order to acquire a complete picture of a quantum process or system.

But notions of complementarity and entanglement have implications far beyond the specific meaning ascribed to them in the orthodox quantum theory of particles, atoms and molecules. Using less formal approaches, examples have been cited from engineering, the cognitive sciences, especially psychology, and philosophy.⁵ Atmanspacher et al took the radical approach of developing a more generalised version of quantum theory which relaxes several of orthodox quantum theory’s axioms, including dependence on Planck’s constant. Called Weak Quantum Theory (WQT),⁵ it differs from orthodox quantum theory in that:

• Complementarity and entanglement are not restricted by a constant like Planck’s constant.

• WQT has no interpretation in terms of probabilities.

• Complementarity and indeterminacy are epistemological in origin not ontological.

As a result, WQT explicitly allows quantum theory’s application into such macroscopic areas as philosophy, psychology and information dynamics and into possible explanations of the dynamics of healing.

Quantum theory and homeopathy

Classical physics and quantum physics differ in an important respect. The former enshrines common sense, for everything considered physical is observable and therefore measurable: this is the leitmotif for all reductionist science and underpins the whole of biomedicine. However, in quantum physics this is not always be the case: not everything considered physical is observable or measurable.³³ So, in quantum physics, there is the concept of the wave function which is not a directly observable entity as such: only its effects are. A wave function is considered to be a multi-dimensional descriptor of a system’s state, whose existence may only be inferred from the observable effects it produces in our ‘reality’.

The reason for this is not because of any fault in measurement; it depends on the mathematical language we use to describe those measurements. Thus, measurement of a quantum state, as with any experiment, provides data in the form of what are called real numbers, eg, the numbers we use everyday like 1, 2, −6, π e, 1/2, √2, etc. But because mathematicians and physicists think in many more than four dimensions, they need a much more versatile number system. And in mathematics, the real numbers are seen as a special case of much larger number sets. One of these is called the complex numbers,³⁴ used to fully describe the multi-dimensionality of quantum states in a way that the real numbers cannot. Complex numbers are irreducible aggregates of real numbers and ‘imaginary’ numbers, based on √-1, which cannot be understood in terms of real numbers.

Real numbers are part of the larger set of complex numbers but not vice versa. Trying to fit a state or a system whose full description requires complex numbers into the real number set is like trying to squeeze a three-dimensional cube into a two-dimensional plane: it does not fit and some information invariably gets lost, notably in this case, the cube’s three dimensionality. It is a similar loss of information in trying to make sense of a quantum state’s complex number description by translating it into the real numbers of hard data, that leads to much of what is considered to be ‘quantum weirdness’.³³

The consequences of the quantum description of reality for our view of the universe are profound. Ultimately it means relinquishing any notion of knowledge of things ‘out there’, ‘in themselves’, separate from our observation of them. We have to come to terms with the unsettling fact that in quantum theory, like the parts of a complex number, the observer and the observed are intimately and irreducibly connected. But what is it about quantum theory that could resonate with homeopathy and other forms of complementary and alternative medicine (CAMs)?

In homeopathy and other CAMs there is a notion of an all-pervading vital force (Vf) which strives to hold the whole organism in balance.³⁵ However, this Vf is not a directly observable entity: like the wave function in quantum theory, it is observed only indirectly through the effects it produces, in this case the patient’s state of health. Thus, through this descriptive similarity of wave function and Vf, there is a similarity in discourse between quantum physics and homeopathy and other CAMs which include a concept of Vf. Perhaps quantum theory’s language of non-commuting operations, non-locality and entanglement could be used to describe the homeopathic process.³⁶

Entanglement in the homeopathic process

There are several ways ideas derived from quantum theory can be used to describe the homeopathic process which may be ordered nominally in terms of the complexity of entanglement between different types of entities.^7c Space limitations do not allow for their detailed consideration here, but see Weingaertner’s contribution in this issue on possible non-local correlations between the different particles of solvent and solute.³⁷ Weingaertner’s model attempts to understand the homeopathic process solely in terms of the potentised medicine as a pharmacologically-active substance, so only one type of entity is considered (Fig. 3).

Walach’s semiotic model combines WQT with two-way entanglement (Fig. 4) between the patient and the remedy,^{[7b] and [38]} while Hyland has developed a two-way patient–practitioner entanglement model called Extended Network Entanglement Theory.³⁹ In the entanglement metaphors I am developing (Fig. 5), three-way patient, practitioner, remedy (PPR) entanglement is considered.⁷ These are based on ideas derived from Greenberger–Horne–Zeilinger three-way entanglement of particles,⁴⁰ and quantum field theory.⁴¹

Fig. 5. PPR entanglement represented geometrically. In (a), Walach’s two semiotic triangles for remedy and patient (also wave functions, ψ_Rx and ψ_Px) are joined by a third for the practitioner ψ_Pr, which are entangled into the PPR ‘state’ represented by ψ_PPR in (b). The multi-dimensional geometry of this state is represented in (c)–(e) and shows the action of the homeopathic operator Πr in ‘reflecting’ this state (d). But the reflection is not passive: by opening out the polyhedra in (d) and superimposing them, it is seen that the reflecting plane also twists the reflection through 60° (e). The ‘space’ in which these wave functions and ‘operations’ take place is a therapeutic state space created by the homeopathic operator Πr, which also functions within it.^{[7] and [42]}

Here, the homeopathic process is regarded as a set of non-commuting complementary observations made by the practitioner. These are local (observations of the patient) and global (observations of the practitioner’s own inner state, how that fluctuates during the consultation, and the state of the patient–practitioner relationship), resulting in the prescription of an homeopathic medicine. Patient, practitioner, and remedy comprise therefore a three-way entangled therapeutic entity, so that attempting to isolate any of them ‘collapses’ the entangled state,⁴² represented geometrically in Fig. 5.

In addition, the Vf may be envisaged as observable only from the amount and severity of the observed signs and symptoms it produces. From this, it is possible to construct a mathematical metaphor for the Vf as a multi-dimensional quantised gyroscope (Fig. 6).⁴³ The slower the Vf gyroscope ‘spins’, the less upright it stands against the braking effects of disease: it begins to ‘wobble’, or, in this metaphor, to express symptoms. Conversely, the therapeutic remedy increases the Vf’s spin rate, throwing off the disease. Thus remedies and diseases may be understood as accelerating and braking ‘torques’ acting on the Vf gyroscope.⁴³

The metaphorical Vf gyroscope precesses in fixed quantised ‘orbits’ as shown and the y and z axes are complex. Symptoms are observed along the real x-axis. Thus, the Vf only ‘appears’ when it expresses symptoms in real space and time, represented by the x-axis in the figure.⁴³

Mathematically, Vf, diseases, and remedies can be represented as ‘wave functions’ (without yet specifying the ‘particles’ involved or ‘interactions’ between them), leading to the prediction that the more potent a remedy, the greater its effect on the Vf. At very low potencies, when a homeopathic medicine is used in a material dose as in conventional medicine, the gyroscopic metaphor approximates in such a way as to deliver predictions about the lack of therapeutic efficacy of highly-diluted homeopathic remedies in line with those of conventional medicine.⁴⁴

In other words, the Vf gyroscope metaphor may be pointing towards a more inclusive paradigm about the effects of remedies that contains both homeopathy and conventional medicine and explains their apparent contradictions. In this sense, the metaphor could be said to parallel theoretical developments in conventional science, where new theories supersede older ones, yet generally include them. Perhaps it suggests that conventional medicine is a smaller subset of a much broader holistic paradigm that includes homeopathy.

Conclusion: a therapeutic Uncertainty Principle?

One application of the PPR entanglement metaphor I have described is to provide a rationale for why RCTs of homeopathy often return equivocal results.⁴⁵ It suggests the double blind RCT ‘collapses’ the three-way patient–practitioner–remedy entangled state in a way analogous to that by which observation collapses a particle’s wave function in the Copenhagen Interpretation of orthodox quantum theory.⁴⁶ Thus, while unobserved, a particle exists in an indeterminate state; its evolution in time expressed as a wave function. Observation causes the wave function to ‘collapse’ to a particle whose complementary position and momentum are related via Heisenberg’s Uncertainty Principle. The profound meaning of this is that the act of observation in part creates that which is observed. Or, even more starkly, “The price of knowledge is the loss of an underlying ontological physical reality”.⁴⁷ In a similar way, the observational procedure of the RCT may ‘collapse’ the three-way entangled state, leading to the loss of the underlying homeopathic effect, a therapeutic equivalent of Heisenberg’s Uncertainty Principle.

But some trials of non-individualised homeopathic remedies have generated positive results.⁴⁵ This could be due to some surviving relic of entanglement from the production process, ironically as a result of a water memory effect. The work of del Guidice et al mentioned earlier, suggested the formation of ‘coherent domains’ within water’s dynamic hydrogen-bonded ‘structure’.²⁶ Such mass correlation over huge numbers of water molecules suggests a form of molecular entanglement.

The tantalising prospect emerges that there could be several levels of entanglement operating during the homeopathic process: the molecular (created during production of the homeopathic medicine), contextually integrated into that occurring between patient, practitioner, and remedy.⁴⁸ Consequently, although double-blind RCTs on non-individualised homeopathic remedies rule out the possibility of over-arching three-way PPR entanglement, the residual molecular entanglement built into the remedy via water memory effects could survive, explaining the positive effects observed in many homeopathic clinical trials.

Ultimately, it will be necessary to find experimental protocols that demonstrate entanglement in the therapeutic process. This is not easy, but clues have been uncovered in double-blind homeopathic pathogenetic trials (HPTs, provings). Many HPTs have not been conducted in a double-blind placebo-controlled manner. After symptoms have been gathered, collation of the data allows a remedy picture to emerge, traditionally one of the central ‘pillars’ of homeopathy.⁴⁹ In two recent double blind placebo-controlled provings, although there were differences in proving symptoms between remedy and placebo groups, there was also overlap or ‘leakage’ of symptoms between them.^{[49] and [50]} Walach et al concluded that as a result of blinding, remedy and placebo groups had become entangled, another demonstration of a possible therapeutic Uncertainty Principle, perhaps? Interestingly, there has been some independent confirmation of this result recently by another research group,⁵¹ and an explanation couched in terms of the PPR entanglement metaphor.^{[45a] and [52]}

Another approach might be to set up a therapeutic analogue of the famous Aspect experiments of the 1980s that demonstrated entanglement between photons.⁸ These experiments depended on the violation of Bell’s Inequalities (our ‘intuition’ based on local realism, makes predictions which differ markedly from those made by quantum mechanics: these predictions are enshrined in Bell’s Inequalities: if they are violated, then the predictions of quantum mechanics, e.g., entanglement, must be true and our intuition wrong). A way forward might be to use the much more general Information Theoretic Bell’s Inequalities—if local realism does not hold, then two systems must carry information inconsistent with the inequalities. The design of suitable experiments is currently being explored.⁵³

In conclusion, what this all seems to be pointing to is that, far from being competing, contradictory explanations, ‘local’ MoW and ‘non-local’ contextually ‘entangled’ effects (like wave-particle duality in orthodox quantum theory) could be complementary and both are necessary in order to make sense of homeopathy’s effects.

Abstract

This paper discusses the nature of the active ingredient of homeopathic ultramolecular dilutions in terms of quantitative physics.

First, the problem of the nature of an active ingredient in ultramolecular dilutions is analysed leading to the recognition of the necessity of characterizing the active ingredient as a non-local quality.

Second, non-locality in quantum mechanics, which is used as a paradigm, is formally presented.

Third, a generalization of quantum mechanics is considered, focussing on the consequences of weakening of the axioms.

The formal treatment leads to the possible extension of the validity of quantum theory to macroscopic or even non-physical systems under certain circumstances with a while maintaining non-local behaviour. With respect to the survival of entanglement in such non-quantum systems a strong relationship between homeopathy and non-local behaviour can be envisaged. I describe how several authors apply this relationship. In conclusion, the paper reviews how quantum mechanics is closely related to information theory but why weak quantum theory and homeopathy have not hitherto been related in the same way.

Introduction

When I started basic research on homeopathy more than 20 years ago I endeavoured to describe homeopathic potencies according to the laws of physics as far as possible. This soon led me to the hypothesis of a field being responsible for the homeopathic phenomenon. In investigating this hypothesis I learned from biophysics that such a field has to be closely related to electromagnetism, because of the ability of living organisms to react in a specific way on electromagnetic signals.¹ I concluded that the mechanism of homeopathic effects must be similar to resonances between electromagnetic waves and started to search for stored patterns of electromagnetic origin or, more generally, of physically measurable properties which differ between potencies and their solvent.

The results of the series of experiments that were carried out with a variety of standard physical–chemical methods² were disappointing. Almost none of the experiments could reproduce results reported in specialist literature, and for no experimental arrangement could the results be forecast. However, the totality of experiments with nuclear magnetic resonance (NMR) showed a clear tendency in favour of a difference between potencies and their solvent in the water- and OH-portions of the ethanol–water-molecule.³ I was quite pleased with this tendency, which is now being investigated by other researchers,⁴ but I realized that looking for effects without having any clue of their significance is hazardous. Therefore, I started building models for the ‘Therapeutically Active Ingredient’ (TAI) and it soon became clear that models for the TAI have to have holistic character.⁵

While playing with models, I developed a construct which I called the ‘Sequential Box Model’ (SBM, see Appendix A). SBM is a thought experiment illustrating that the homeopathic phenomenon can be treated within physics with no consideration of the degree of dilution. Furthermore, the SBM explicitly underlines the long-standing presumption that for a TAI to emerge during the potentization procedure a quality beyond ordinary correlation between particles has to occur or be in existence already.

About this time the idea of the so-called ‘quantum computing’ was proposed in computer science.^{[6] and [7]} This involves the idea of non-local correlations between states of entities. For my work, such non-local behaviour was the missing link between the SBM and a possible TAI, particularly as it was already known that non-local behaviour can occur in non-quantum systems under certain circumstances. The relationship between non-local behaviour of events in nature and the homeopathic phenomenon may give a clue to the ‘nature of the active ingredient in ultramolecular dilutions’ (NAIUD). It is the aim of this paper to analyse this relationship without going too far into technical details.

Necessity of a general principle

When we talk about the active ingredient of ultramolecular dilutions as used in homeopathy, we mean a non-material quality which—according to the principles of homeopathy—can be traced back to a substance. Moreover, this quality is understood to be able to make the symptoms of a patient disappear when administered via a vehicle. Many people call this quality ‘information’. Let us first look at the set of events that are required for a therapeutic active ingredient to develop out of a substance. In this context, the existence of a TAI is temporarily assumed as being proven by successful treatment (Figure 1).

1. First of all, a proving (homeopathic pathogenetic trial) must have been conducted resulting in a drug picture with specific symptoms.

2. A mother tincture is prepared from the substance.

3. Apart from some specific procedures for the preparation of low potencies that depend on the nature of the substance itself, the mother tincture is potentized stepwise with no consideration of the degree of dilution. Dilutions far beyond Avogadro’s number are used in daily practice.

4. When a homeopathic potency is prescribed, this is done according to the law of similars without consideration of the occurrence or not, of any molecule of the original substance in the medicine administered.

5. An artificial disease is triggered off resulting in healing.

These points demonstrate that the active ingredient of homeopathic potencies might have a variety of possible originators, especially when we only look at the squares and arrows in Figure 1 separately. There is no reason as to why two or more of these originators should complement one another. But if we look at Figure 1 as a whole, the necessity of a general principle becomes obvious. For such a principle, the symptoms of the homeopathic drug picture, the principle of releasing hidden energies of the substances by potentizing, the law of similars and the triggering of an artificial disease are specific projections. The problem is, how to specify this principle, especially with respect to the following questions:

1. Could such a general principle possibly be derived from the presence of a physical field?

2. For ultramolecular dilutions, interactions between molecules of the solute and those of the solvent do not make sense in terms of current scientific understanding. How can this be resolved?

3. Are there any reliable arguments for a concept of a global influence being responsible for an active ingredient in homeopathic potencies? Rupert Sheldrake’s morphogenetic field⁸ might serve as an example of such a concept.

In physics, fields are inevitably linked to interaction between material partners via interaction-particles. Photons, for instance, are the interaction-particles of the electromagnetic field.⁹ Thus, potentization as well as treatment with potencies—procedures that implicitly do not depend on matter–matter-interaction—are not primarily based on physical fields.

Figure 1. Schema of events which are required for a TAI to: (a) develop out of a substance, and (b) proved to be existent by successful treatment. Arrows represent procedures, they map states onto states.

Both procedures, however, suggest mind–matter and matter–mind correlations.

1. Neither a specific chemical nor a specific physical property of the original substance is known to be transferred during the preparation of potencies although mother tinctures, which of course contain many molecules of the original substance, are mandatory for a starting point of this procedure. Potentization here appears to embody a procedure that relates matter to mind.

2. No common donor–acceptor-mechanism is known to be responsible for the effects of potencies. Treatment appears to embody a procedure that relates the ‘mind of matter’ to the ‘mind of illness’. The latter of course itself is strongly related to biological matter and is often looked upon as a relationship belonging to psychosomatics.

Are these correlations better described by interaction mechanisms that are not linked to particles? A possible alternative is non-local correlations, known from specific effects in quantum physics. Roughly speaking these correlations have the following characteristic:

1. Non-local correlations between systems or entities represent a real simultaneous behaviour of the correlation partners because no interacting particles (which have a finite speed and therefore cause a time delay) are necessary for interaction.

2. Non-local correlations are not able to interchange matter but only non-material information.

3. Non-local correlations are, in principle, independent of spatial distances.

How non-locality arose

Although Einstein was one of the founders of quantum physics, he did not accept quantum mechanics as to be a complete description of the phenomena of the micro world. He explained the reason for this attitude in a paper which he published with Podolsky and Rosen in 1935. In this famous paper, the three physicists described a thought experiment in which two physical quantities have simultaneous reality.¹⁰ For Einstein, this was a counter example for the completeness of quantum mechanics as a description of nature and for the rest of his life he did not change this attitude. He was not willing to accept counter-intuitive features in the description of nature. Schrödinger later on called this counter-intuitive property of quantum systems ‘entanglement’. Only three decades later, John Bell¹¹ gave a theory-based criterion by which it was possible to decide whether a system is a quantum system or not. This criterion was applied in 1982 by Aspect and co-workers to an experimental arrangement in which they showed, for the first time, that entangled states can occur in quantum systems.¹² Since then many properties of systems in micro-physics have been demonstrated in experimental arrangements based on entanglement.^{[5], [6] and [7]} All have one thing in common: ‘Entanglement in quantum systems’.

What is entanglement?

Entanglement is a highly counter-intuitive quality of quantum systems. The fact that entanglement is irrelevant to Newtonian physics does not justify the assumption that quantum physics is the only field where entanglement occurs. At least theoretically, entanglement can occur in any system that fulfils a certain set of axioms. Entanglement comes in various guises and it is not easy for non-specialists to see whether a phenomenon belongs to the category of entangled systems or not. For our purposes, it should suffice to get a clue what entanglement is, without too much technical fuss. Readers who are interested in a more precise explanation are referred to Appendix B.

As an example let us imagine a secluded island exclusively inhabited by females. Being asked what human beings are, the inhabitants of this island would most probably point their fingers at themselves. Similarly, the inhabitants of another island exclusively inhabited by males would identify human beings with males. For the rest of the world, human beings are females as well as males. This is a description of a factual connection, where a generic quality in a system has a different meaning in its subsystems. Furthermore, if we look at pairs of human beings there might be couples among them in the rest of the world, in total contradiction to the local meaning in the two islands.

A generalization of this example leads to the following. Let p₁ be a particle in a system A and let p₂ be another particle in a system B. System A and system B are assumed to be disjoined, ie have no common points/particles. System A rules the behaviour of particle p₁ and system B does the same for particle p₂ (see Figure 2).

Figure 2. Schema of two entangled systems A and B. p₁ and p₂ are assumed to be correlated. Seen from (A+B) correlation can be observed. Seen from A or B only local observations are possible.

It might be that states of the totality of the two systems occur which cannot be recognized in system A or in system B alone, but are exclusively linked to the recognition of (A+B) as a third generic system. In the above example as well as in the following generalization constellations, in which global observations are not compatible with local ones, are possible. This is the idea behind entanglement.

Weakening the axioms of quantum mechanics

Quantum mechanics deals with states z_i and observables P, Q of quantum systems. Examples of observables are momentum, angular momentum, etc. Observables are thought to act as maps on the set of states. So, an observable P maps a state z₁ into another state z₂. Onto z₂ a second observable Q may be applied resulting in a state z₃. Unlike in classical mechanics in quantum mechanics one does not always have P(W(z))=Q(P(z)) or equivalently:

PQ–QP≠0,

where ‘’ is to be interpreted as ‘apply to’, where ‘0’ on the right-hand side of this inequality denotes the ‘zero-operator’ and where states ‘z’ have been omitted. Such a relation is known as a ‘commutation-relation’ of the two observables. Using states and observables as well as their relation to each other, quantum mechanics can be described as an algebraic system whose behaviour is ruled by a set of axioms that reflect the physical properties.In 2002, Atmanspacher et al. published¹³ the idea that weakening the axioms of quantum theory (weak quantum theory, WQT) could lead to theories that are no longer quantum systems or even physical systems at all, but which still have the property of possible entanglement. To be more precise, Atmanspacher et al. considered systems that comply with the following conditions (see also¹⁴):

1. Systems are any part of reality.

2. Systems are assumed to have the capacity to reside in different states. The set of states is not assumed to have the structure of the above-mentioned abstract space.

3. Observables are features of a system which can be investigated. They map states into states.

4. The composition PQ of two observables is also an observable. P and Q are called compatible if they commute (ie PQ–QP=0).

5. To every observable P there is a set of different (possible) outcomes.

6. There are special observables (propositions) whose possible outcomes are either ‘yes’ or ‘no’. They follow the laws of ordinary proposition logic and have specific spectral properties (omitted here).

Within these conditions entanglement arises if global observables P pertaining to all of a system are not compatible to local observables Q pertaining to parts of the system (iePQ–QP≠0).

WQT and homeopathy

Since WQT systems are not necessarily quantum systems, WQT could be a tool to develop models for phenomena which are not quantum but have features which resemble entanglement, for instance, homeopathy. Several authors therefore have applied WQT to the homeopathic phenomenon. Walach, one of the co-authors of the original WQT paper,¹⁵ presented a model in which the two semiotic processes ‘substance and potency’ as well as ‘drug picture and symptoms of the patient’ are assumed to be entangled by the law of similars. Milgrom has sketched a model for the homeopathic phenomenon in which the three pairs ‘Patient and practitioner’, ‘patient and remedy’ as well as ‘practitioner and remedy’ are assumed to be entangled in pairs.¹⁶ In a metaphorical way he derives, in succeeding papers, from this entanglement triangle an astonishing variety of principles of homeopathy.

Both models presuppose the validity of WQT for the specific situation in homeopathy and Milgrom, at least, deduces implications which reflect the way homeopaths think. In terms of logic, the approach of these two models is called the sufficiency part of a proof. The necessity part would be the proof that the assumptions which underlie homeopathy such as the potentization, the law of similars, etc., fit the preconditions of WQT.

I have tackled the TAI problem in a previous paper.¹⁷ This is where the SBM (see Appendix A) becomes relevant as a thought model, because it characterizes homeopathic potencies as a real physical system in which an unknown inner correlation is sought. In essence, paper¹⁷ showed that sets {J_i1,…,i_m·σ_i1,…,i_m·σ_i1,…,i_m} of spin-like states, where indices i₁,…,i_m vary over permutations, fit the axioms of WQT for an arbitrary big system B_N in the SBM. The sets {J_i1,…,i_m·σ_i1,…,i_m·σ_i1,…,i_m} are a generalization of couplings (J_ik·σ_i·σ_k) of two spins, in NMR-theory, for instance. The generalization strongly suggests to investigate the possibility of global couplings instead of pair-to-pair couplings.

In summary, a number of arguments exist for non-locality being the general principle underlying the NAIUD. Quantum mechanics, however, cannot be considered, without further investigations, the theoretical frame for the NAIUD. The paradigm is rather non-locality. Quantum physics is merely the scientific discipline where non-locality has proven to occur in reality. Figure 3 gives a schematic classification of phenomena which can be treated within quantum mechanics, and those which have less structure in the set of their states and therefore need another theoretical environment, WQT. Questions concerning the NAIUD might even go beyond WQT.

Entanglement and information in quantum physics and beyond

It is the purpose of this section to explain the considerable difficulties one should be aware of when applying WQT instead of normal quantum mechanics to systems in nature.

This will be exemplified by the difficulties which arise when the attempt is made to translate ‘informational content’ (=entropy) in a quantum system to a system which is not quantum but which can be investigated by WQT. For formally correct representations of the factual connections given here, the reader is referred, for instance, to.⁶

The key concept of classical information theory is that of Shannon entropy. According to this concept, the entropy of a random variable A quantifies how much information we gain, on average, when we learn the value of A. Conversely, the entropy of A measures the amount of uncertainty about A before we learn its value. Thus, on the one hand, entropy measures the uncertainty associated with a classical probability distribution. On the other hand, in quantum ensembles density operators ρ, which represent the statistics of ensembles of different molecules in different states, formally replace probability distributions.

It was John von Neumann’s brilliant insight that in quantum mechanics the entropy S(ρ) of ρ can be expressed by the formula

where λ_x are the eigenvalues of the density operator ρ. If entanglement between two subsystems of a quantum system occurs and if one considers the density operators of these subsystems separately it can be shown that the von Neumann entropy of one of these reduced density operators is a measure of the degree of entanglement. This measure has an upper bound log(s), where s (the Schmidt-number) is the dimensionality of an abstract space in which these states ‘live’. Clearly, the bigger the s, the more the particles or states entangled. Applied to an arbitrary box B_N of the SBM this suggests that the bigger the box B_N is, the larger s has to be chosen and therefore the larger the measure of the amount of information.These considerations, however, presuppose entanglement of those particles being directly concerned. If we turn to a situation where WQT has to be applied instead of quantum mechanics, many of the basic constituents are no longer present or at least no longer adequately defined. For instance, if the set of states is structured so poorly then the above formula for von Neumann entropy makes no sense.

Discussion

The principle of non-local behaviour of systems in nature, first investigated in the context of the counter-intuitive phenomena of quantum physics, is not necessarily restricted to physics at the micro scale. This is the essence of WQT. Roughly speaking WQT shows that in every system where local and global observables do not commute with each other non-local behaviour is possible. For some authors, WQT was the reason for using non-locality to characterize the nature of the active ingredient of ultramolecular dilutions. Some models have simply drawn consequences from such a possible generalized non-locality, another looks at the real potentization procedure, asking what non-locality might contribute to an active ingredient. But WQT is not known to be powerful enough to describe the NAIUD entirely.

So the question arises, why considered WQT in such detail in connection with homeopathy? The answer is simple. With WQT, for the first time, special emphasis is placed quantitatively on entanglement as an idea. Moreover, WQT has shown to be a powerful tool for the characterization of the physics of the class of mathematical problems which arise when the NAIUD is to be described.

It is a great temptation to use WQT as a special way of describing the laws of quantum physics. People who do so tend to ignore the restraints given of WQT and use it as a theory applicable to everything, including the NAIUD. This is certainly not the right way to describe the NAIUD. An attempt to characterize the informational content of a system to be investigated by WQT, shows that it is not easy to generalize the concept in quantum mechanics to WQT or beyond.

Of course, all these considerations do concern the NAIUD in modelling situations. The question is, why do such work instead of looking for the TAI in experiments? The answer is that model building is a method of finding a way of thinking which allows us to understand a set of phenomena in a wider context. In contrast, experimental work tends to reductionism. I hope that both tendencies will ultimately meet.

Appendix A. The sequential box model (SBM)

Imagine a certain volume of mother tincture is present in a box B₀. Then imagine the contents of B₀ are poured into another box B₁, 10 times bigger than B₀ and already 9/10th full of solvent. Imagine then B₁ being vigorously shaken as in the preparation procedure of homeopathic potencies. Imagine then the whole content of B₁ being poured into another box B₂, 10 times bigger than B₁ and again 9/10th full of solvent.

This procedure can be continued to an arbitrary box B_N and it is clear that:

1. In every Box B_N the whole volume of mother tincture is present, ie the problem of high potencies can be, at least in a thought experiment, treated physically.

2. If one attempted to conduct this experiment in reality the procedure would come to an end very soon because of the unrealizable dimensions of the boxes.

3. The higher N grows the less probable is the occurrence of a molecule in a random sample taken out of B_N. This means that in B_N an additional property has to be present which carries the information of B₀. This property has to be non-local.

Appendix B. Entanglement

Mathematicians represent every point in the three-dimensional space of our experience as a sum of multiples of vectors of unit lengths in the x-, y– and z-axes. In the same way, they often represent objects in abstract spaces as sums of multiples of basic elements of these spaces. A direct application of this to quantum physics leads to the following.^{[6] and [7]}

The states of quantum systems are mathematically represented by elements (points in) of an abstract Hilbert-space H. If points in this space are denoted by ψ and if the basic elements of H are denoted by _i (i=1,2,…), representations of states look like

This is commonly known as the principle of superposition in quantum mechanics, ie a wave function ψ is the superposition of multiples a_i of basis ‘waves’ _i. In case of two particles forming two different systems we have the two representations:

where the numberings (1) and (2) are used to distinguish between the two. For the sake of clarity, we also index the Hilbert-spaces belonging to each of these representations (and get H₁ and H₂, respectively) although they are usually identical.The crucial point now is the consideration of a system consisting of the two particles as a whole. In this case, it is necessary to construct another Hilbert-space H=H₁H₂ out of H₁ and H₂ in such a way that this new system ‘lives’ in H₁ and in H₂ at the same time. In order to achieve this, a so-called tensor-product H₁H₂ is formed. This is a new Hilbert-space whose points have the form

where Φ_i,j denote basis elements in H=H₁H₂ and c_i,j their multiples. Entangled states are those (ψ⁽¹⁾ψ⁽²⁾) for which the multiples c_i,j cannot be written as

ci,j=aibj,

with a_i and b_j being the multiples from above and independent from each other.Remarks

1. The above relation between states can be interpreted as the possible arising of additional qualities when two single systems are looked upon as a whole.

2. The set of entangled states in most of quantum systems is not empty. For many systems, the subset of possibly entangled states is much bigger than the non-entangled.

3. The above characterization is not restricted to pairs of particles.

4. States (ψ⁽¹⁾ψ⁽²⁾) in H=H₁H₂ which cannot be split into products of pure states in H₁ and H₂, respectively, might be imagined as the pure states of the composite system.

5. The description of entanglement in quantum mechanics, which is a counter-intuitive, strongly depends on a mathematical apparatus with a rich structure.

‘Homeopathic dilutions’ and ‘Memory of Water’ are two expressions capable of turning a peaceful and intelligent person into a violently irrational one,’ as Michel Schiff points out in the introduction of his book ‘The Memory of Water’. The idea of the memory of water arose in the laboratory of Jacques Benveniste in the late 1980s and 20 years later the debate is still ongoing even though an increasing number of scientists report they have confirmed the basic results.

This paper, first provides a brief historical overview of the context of the high dilution experiments then moves on to digital biology. One working hypothesis was that molecules can communicate with each other, exchanging information without being in physical contact and that at least some biological functions can be mimicked by certain energetic modes characteristics of a given molecule. These considerations informed exploratory research which led to the speculation that biological signaling might be transmissible by electromagnetic means. Around 1991, the transfer of specific molecular signals to sensitive biological systems was achieved using an amplifier and electromagnetic coils. In 1995, a more sophisticated procedure was established to record, digitize and replay these signals using a multimedia computer. From a physical and chemical perspective, these experiments pose a riddle, since it is not clear what mechanism can sustain such ‘water memory’ of the exposure to molecular signals. From a biological perspective, the puzzle is what nature of imprinted effect (water structure) can impact biological function. Also, the far-reaching implications of these observations require numerous and repeated experimental tests to rule out overlooked artifacts. Perhaps more important is to have the experiments repeated by other groups and with other models to explore the generality of the effect. In conclusion, we will present some of this emerging independent experimental work.

Historical overview: the early history of high dilution experiments

Presenting a brief history of what is known as the ‘Memory of Water’ is not an easy task mainly because one of the main actors, Jacques Benveniste, is no longer with us (Figure 1). There are always many controversies around cutting edge science, and especially with those whose lives have been spent pursuing unorthodox trails.

I first met Benveniste during a FASEB meeting in Atlanta in 1981 and joined his laboratory a few years later to set up my own Immunology team. I had the good fortune of being able to collaborate with him for over 16 years. At that time, he was at the top of his fame and gained an international reputation as a specialist on the mechanisms of allergies and inflammation with his discovery of the ‘Platelet Activating Factor’ (paf-acether) in 1970.^{[1] and [2]} Throughout his long career, working both in the US and in France, he was responsible for the development of new ways of approaching inflammation including the patenting by the French National Institute of Health and Medical Research (INSERM) of his innovative allergy test using blood cells called basophils (FR-patent-7,520,273). Jacques’ research into allergies took him deep into the mechanisms which create such responses: understanding how the smallest amount of a substance affects the organism. The life and work of Jacques Benveniste was not only written in water.

In the early 1980s, while heading up the unit INSERM 200, Jacques took a new member onto his staff, a young medical doctor, Bernard Poitevin, whose side-interest was homeopathy. ‘He asked me if he could try my basophil degranulation test on some homeopathic preparations’, Jacques recalled, ‘and I remember distinctly saying “OK, but all you will be testing is water”.’ Thus, Jacques expressed his skepticism but accepted the proposal.

After 5 years of research they empirically observed that highly dilute (i.e., in the absence of any physical molecule) biological agents nevertheless triggered the relevant biological systems. Intrigued but cautious, Jacques was a man who adhered to the facts. He ordered a two-year long series of retests, but the same results kept recurring. Finally, Poitevin and Benveniste submitted two papers which were published in peer review journals.^{[3] and [4]} Here, the work was treated as conventional research like many other manuscripts from peer-reviewed journals which can be found in the scientific literature on the effect of high dilutions (HD) (review in^{[5] and [6]}).

Following accepted scientific practice, Jacques then asked other laboratories to try to replicate the findings. In 1988, scientists from six laboratories in four countries (France, Canada, Israel and Italy) co-authored an article showing that highly diluted antibodies could cause basophil degranulation. This was established under stringent experimental conditions such as blind double-coded procedures. Further, the experimental dilution (anti-IgE) and the control one (anti-IgG) were prepared in exactly the same manner, with the same number of dilution and agitation sequences. The article was submitted to Nature.⁷ Nature‘s referees could not fault Benveniste’s experimental procedures but could not comprehend his results. How can a biological system respond to an antigen when no molecules of it can be detected in the solution? It goes against the accepted ‘lock-and-key’ principle, which states that molecules must be in contact and structurally match before information can be exchanged. In the paper, Jacques suggested that specific information must have been transmitted during the dilution/shaking process via some molecular organization occurring in the water.

Finally, the editor of the journal, John Maddox agreed to publication, on condition that a ‘committee’ could verify Benveniste’s laboratory procedures. In July 1988, after two weeks after publication, instead of sending a committee of scientific experts, Maddox recruited—James Randi, a magician, and Walter Stewart, a fraud investigator. The three of them spent 5 days in the laboratory. Well, you all know what followed. Nature‘s attempted debunking exercise failed to find any evidence of fraud. Nevertheless, they concluded that Benveniste had failed to replicate his original study.⁸ This marked the beginning of the ‘Water Memory’ war, which placed him in a realm of ‘scientific heresy’. As Michel Schiff later remarked in his book: ‘INSERM scientists had performed 200 experiments (including some fifty blind experiments) before being challenged by the fraud squad. The failure to reproduce⁸ only concerned two negative experiments’.⁹ Benveniste replied to Nature¹⁰ and reacted with anger, ‘not to the fact that an inquiry had been carried out, for I had been willing that this be done… but to the way in which it had been conducted and to the implication that my team’s honesty and scientific competence were questioned. The only way definitely to establish conflicting results is to reproduce them. It may be that we are all wrong in good faith. This is not crime but science…’.

As a consequence of the controversy that ensued, Jacques became increasingly isolated. Nonetheless the team repeated the work on a larger scale, entirely designed and run under the close scrutiny of independent statistical experts, and confirmed the initial findings in Nature.¹¹ These further experiments have been coolly received or ignored by most scientists at least partly because, given Jacques’ now-acrimonious relationship with Nature, they were published in a less renowned journal.

To date, since the Nature publication in 1988, several laboratories have attempted to repeat Benveniste’s original basophil experiments. Most importantly, a consortium of four independent research laboratories in France, Italy, Belgium, and Holland, led by M. Roberfroid at Belgium’s Catholic University of Louvain in Brussels, confirmed that HD of histamine modulate basophil activity. An independent statistician analyzed the resulting data. Histamine solutions and controls were prepared independently in three different laboratories. Basophil activation was assessed by flow-cytometric measurement of CD63 expression (expressed on cytoplasmic granules and on the external membrane after activation). All experiments were randomized and carried out under blind conditions. Not much room, therefore, for fraud or wishful thinking. Three of the four labs involved in the trial reported statistically significant inhibition of the basophil degranulation reaction by HD of histamine as compared to the controls. The fourth lab gave a result that was almost significant. Thus, the total result over all four labs was positive for histamine HD solutions.^{[12] and [13]} ‘We are,’ the authors say in their paper, ‘unable to explain our findings and are reporting them to encourage others to investigate this phenomenon’.

Different attempts have been made to substantiate the claim that serial dilution procedures are associated with changes in the water’s physical properties (^{[14] and [15]}and see Louis Rey contribution in this issue pages 170–174). Yet, the challenge of understanding the mechanisms of how HDs work, and the role of water in them, is a difficult one to say the least. Several possible scenarios have been suggested. One proposed by Giuliano Preparata and Emilio Del Giudice, is that long range coherent domains between water molecules (quantum electrodynamics, QED) gives high dilution laser-like properties.^{[16] and [17]} When the field matches the kinetic of the reaction, the latter becomes functional as the optimal field strength as for a radio receiver. It was to a scientific meeting in Bermuda that took place a few months before the Nature ‘affair’ erupted that these two physicists working at Milan University brought the theoretical basis for the memory of water. Another scenario predicts changes in the water structure by forming more or less permanent clusters.¹⁸ Other hypotheses will be discussed in this issue. High dilution experiments and memory water theory may be related, and may provide an explanation for the observed phenomena. As M. Schiff points out, only time and further research will tell, provided that one gives the phenomena a chance.⁹

Exploring the physical nature of the biological signal

Despite the difficulties after the Nature fracas, Jacques and his now-depleted research team continued to investigate the nature of the biological activity in high dilutions and aimed at understanding the physical nature of the biological signal. In his Nature paper, Jacques reasoned that the effect of dilution and agitation pointed to transmission of biological information via some molecular organization going on in the water. The importance of agitation in the transmission of information was explored by pipetting dilutions up and down ten times and comparing with the usual 10-s vortexing. Although the two processes resulted in the same dilution, basophil degranulation did not occur at HD after pipetting. So transmission of the information depended on vigorous agitation, possibly inducing a submolecular organization of water or closely related liquids (ethanol and propanol could also support the phenomenon). In contrast, dilutions in dimethylsulphoxide did not transmit the information from one dilution to the other. In addition, heating, freeze-thawing or ultrasonication suppressed the activity of highly diluted solutions, but not the activity of several active compounds at high concentrations. A striking feature was that molecules reacted to heat according to their distinctive heat sensitivity, whereas all highly diluted solutions ceased to be active between 70 and 80 °C. This result suggested a common mechanism operating in HDs, independent of the nature of the original molecule. In addition, in 1991 and in collaboration with an external team of physicists (Lab. Magnetisme C.N.R.S.-Meudon Bellevue, France), it was shown in twenty four blind experiments that the activity of highly dilute agonists was abolished by exposure to a magnetic field (50 Hz, 15×10⁻³ T, 15 min) which had no comparable effect on the genuine molecules. Moreover, it is worth pointing out that a growing number of observations suggest the susceptibility of biological systems or water to electric and low-frequency electromagnetic fields.^{[19], [20] and [21]} In addition, what is suggested from the literature is a possible role of electromagnetic fields regarding informational process in cell communication.^{[22], [23] and [24]}

At this stage, Jacques hypothesized that transmission of this ordering principle was electromagnetic in nature and move on to the idea that molecules could communicate via specific electromagnetic waves. If so, what molecule vibration modes are efficient and how can these signals be used to mimic some of the biological functions of a molecule without its physical presence?

From high dilution to digital biology

It was at the beginning of the nineties that a homeopathic physician, E. Attias convinced Jacques to try out an electrical device that he claimed transmitted chemical information. After a few positive trials with this machine, Jacques had another one built, which was used for later experiments. This second device was essentially a standard audio amplifier that, when connected to another coil, behaves as an audio-frequency oscillator. Between 1992 and 1996, we performed a number of experiments showing that we could transfer, in real time, molecular signals indirectly to water or directly to cells. Briefly, cells were placed in a 37 °C humidified incubator on one coil attached to the oscillator, while an agonist (or vehicle as control) was placed on another coil at room temperature. Here, the transfer was not a two step-process, as when water acts as an intermediary recipient of the molecular signal. In one such exploration, we showed that molecular signals associated with a common phorbol ester (phorbol-myristate-acetate) could be transmitted by physical means directly to human neutrophils to modulate reactive oxygen metabolite production. In 1996, I submitted an article about these experiments to several prestigious journals. The article was flatly rejected each time, on the grounds that we could not explain the underlying mechanism, in spite of the referees’ general opinions that our work was ‘state-of-the-art’ and was ‘provocative and intriguing and we have gone to great lengths to try to eliminate any biological variables that could bias our results.’ It was finally published in 2000.²⁵ Appended to this article were two affidavits, one from a French laboratory (F. Russo Marie, INSERM U332, Paris, France) testifying that they supervised and blinded the experiments we did in this laboratory; the other from an US laboratory (W. Hsueh, Department of Pathology, Northwestern University, Chicago) testifying that they did some preliminary experiments similar to ours, without any physical participation on our part, and detected the same effect.

Because of the material properties of the oscillator and the limitations of the equipment used, it is most likely that the signal is carried by frequencies in the low kilohertz range.²⁶ These considerations led to the establishment in 1995 of a more sophisticated procedure for the recording and retransmission of the molecular signals. DigiBio, a company that Jacques had set up in 1997 to finance his research, obtained in 2003 an approval for one of his French patents by the US Patent Office (6,541,978: method, system and device for producing signals from a substance biological and/or chemical activity). The characteristics of the equipment are described in Figure 2 and in.²⁶ Briefly, the process is to first capture the electromagnetic signal from a biologically active solution using a transducer and a computer with a sound card. The digital signals are stored (Microsoft sound files *.wav). The signal is then amplified and ‘played back’, usually for 10 min, from the computer sound card to cells or organs placed within a conventional solenoid coil. The digitally recorded signals can also be played back into untreated water, which thereafter will act as if the actual substance was physically present.

From 1995 to the present, several biologically active molecules (eg histamine, acetylcholine, caffeine, PMA, Melagatran… even homeopathic medicines such as Arnica montana) have been recorded, digitized and replayed to biological systems sensitive to the original molecular substance. Several biological models were used. The first one was a commonly used system by pharmacologists, called the Langendorff preparation. By injecting different vasoactive substances into the coronary artery of an isolated, perfused guinea pig heart and measuring the coronary flow, you can quantify the vasoconstricting or vasodilating effect of the agent. In typical experiments, the signal of acetylcholine (or water as control), a classical vasodilating molecule was recorded and digitized. The signal was then amplified and ‘played’ back onto water. The signal-carrying water is then injected into the isolated heart, and consequently the coronary flow increased. Interestingly, atropine, an acetylcholine inhibitor, inhibited both the effects of the molecular acetylcholine as well as the digital signal of acetylcholine. Of note, the order of the conditions and their repetitions was always randomized and blinded. Other models include: human neutrophil activation; detection of the recorded signal of bacteria (E. Coli and Streptococcus) by playing them to a biological system specific to the bacterial signal and; the inhibition of fibrinogen coagulation by a Direct Thrombin Inhibitor. Further details of three of these salient biological models have been previously described.²⁶ Together, these results suggested that at least some biologically active molecules emit signals in the form of electromagnetic radiation at a frequency of less than 44 kHz that can be recorded, digitized and replayed directly to cells or to water, in a manner that seems specific to the source molecules.²⁶

Assuming that we give credence to the phenomena described, one question naturally springs to mind: what do molecule vibration modes sound like? Can measurable signals been identified in the form of low frequency spectral components? Didier Guillonnet, an engineer in computer science, and at the time, a close collaborator of Jacques Benveniste admitted, ‘When we record a molecule such as caffeine, for example, we should get a spectrum, but it seems more like noise. We are only recording and replaying; at the moment we cannot recognize a pattern although the biological systems do.’ Jacques called this matching of broadcast with reception ‘co-resonance,’ and said it works like a radio set.

Among the various theoretical problems associated with such a signal, two appear particularly relevant. First, how is such information using water as an intermediary detected amongst much electromagnetic noise? In fact, it has been suggested that stochastic resonance is an important mechanism by which very weak signals can be amplified and emerge from random noise.²⁷ Second, the limitations of the equipment used here, suggest that the signal is carried by frequencies in the low kilohertz range, many orders of magnitude below those generally associated with molecular spectra (located in the infrared range). However, molecules may also produce much lower ‘beat’ frequencies (Hz to kHz) specific for every different molecule. The ‘beat frequency’ phenomenon may explain this discrepancy, since a detector, for instance a receptor, will ‘see’ the sum of the components of a given complex wave.²⁸ Clearly, more experimental and theoretical work is needed in order to unveil the physical basis of the transfer (and storage?) of specific biological information either between interacting molecules or via an electronic device.

Replicability: Although since the very beginning we have placed a great deal of emphasis on carrying out our work under the highest standards of methodology and that great effort has been made to isolate it from environmental artifacts, attempts to replicate these data in other laboratories yielded mixed results. For instance, in 1999, Brian Josephson, Nobel Laureate for Physics in 1973 invited Benveniste to the Cavendish Laboratory in Cambridge. He said, ‘We invited him to learn more about the research which seems both scientifically interesting and potentially of considerable practical importance. Jacques definitely recognized there was a problem with reproducing the effect. The situation seemed to be that in some circumstances you had reproduction and in others you didn’t; but the overall results were highly significant.’ We then realized the difficulty in ‘exporting’ a method, which is very far from conventional biology. There are many key variables that might be involved like, water purification, the container shape and material being used, the purity of chemicals, atmospheric conditions…. Only if these underlying variables are known could the experiments be reproducible. When the transfer is a two-step process using water as an intermediary support for transmitted molecular signals, it takes even more stringent conditions for the experiments to be repeatable. The digital signal is replayed onto the water, which may take or not take the signal depending, for instance, upon the local electromagnetic conditions. In this regard, it is interesting to note that the ‘informed water’ as in the HD experiments, loses its activity after heating or being exposed to magnetic fields.

More surprising and mysterious was the fact that in some cases certain individuals (not claiming special talents) consistently get digital effects and other individuals get no effects or perhaps block those effects (particularly when handling a tube containing informed water). The inhibition of fibrinogen–thrombin coagulation by a digitized thrombin inhibitor is a model particularly sensitive to experimenter effects and therefore may account for the difficulty in consistently replicating this experimental system. Despite the precautions taken to shield the information transfer equipment from magnetic or electromagnetic pollution, very little concern has been given to possible subtle human operator effects.²⁹ We dealt with this problem in some of our own studies and also in the course of one independent replication.³⁰

The present situation

Now that Jacques Benveniste is no longer with us, the future of the ‘digital biology’ is in the hands of those who have been convinced of the reality of the basic phenomena. It is up to them to explore with other models the generality of the effect. Most likely they will succeed if they combine full biological and physical skills to understand the nature of the biological signals.

In this regard, since June 2005, Luc Montagnier, the co-discoverer of HIV, is conducting experiments (detection of the recorded signals of various micro-organisms derived from human pathologies) which, confirm and extend the original finding. In 2006, he set up a company called Nanectis. Perhaps the most impressive emerging data is from a US group located in La Jolla, CA.

In barely four years, they have conducted novel research programs and expanded the original technology into a series of potential industrial applications. Since 2004, they have obtained several US patents (6,724,188; 6,952,652; 6,995,558; 7,081,747) and applied for International Patents (WO 06/015038: system and method for collecting, storing, processing, transmitting and presenting very low amplitude signals; WO 06/073491: system and method for producing chemical or biochemical signals). They can improve the molecular signal recording in particular by using both magnetic and electromagnetic shielding coupled to a superconducting quantum interference device (SQUID). The system records a time-series signal for a compound; the wave form is processed and optimized (selected noise amplitude, power setting…) to identify low-frequency peaks that are characteristic of the molecule being interrogated (Molecular Data Interrogation System, MIDS). The optimized signal is played back for various periods of time to sensitive biological systems. For instance, they describe one interesting model particularly relevant to the specificity of the molecular signal transmission effect. The arabinose-inducible bacterial system with a lac operon is inducible by signals from the L (+) arabinose form but not from the D (−) arabinose inactive isomer or the white noise control. Other systems include digital herbicides and plant growth regulator as well as pharmaceutical compounds such as Taxol ^®, a prototype for a class of anticancer drugs. For instance, in a classic in vivo mouse xenograft model, the digital Taxol was assessed by the growth inhibitory potential of a human breast tumor. The results revealed that tumor growth, by day 36, was as statistically significantly inhibited in the group treated with the Taxol signal, as it was in the control group treated with actual molecular Taxol. If these new experimental observations can be validated, we will have added yet another valuable piece to the puzzle.

Although a theoretical explanation of how the memory of water might work must still be explored, the fact that the effective transmission of molecular signals has now been observed by independent teams using different biological systems, provides a strong additional basis to suggest that the phenomena observed by Jacques were not due simply to laboratory artefacts.

Whatever knowledge ongoing and future investigation may bring, the difficult road that Jacques travelled by opposing the automatic acceptance of received ideas, will have contributed to sustaining freedom in scientific research and putting the emphasis back where it belongs, on observable fact.

Homeopathic medicines are currently used in medical practice, despite controversy about their effectiveness. The preparation method is based on extremely high dilutions of many substances in water, far beyond any detectable level. For this reason, it has been suggested that water could retain a ‘memory’ of substances that have been dissolved in it before the successive dilutions. The paper stresses the fact that this idea is not compatible with our knowledge of pure water. If an explanation on physical grounds is to be found, research must focus in other aspects of the preparation, such as the presence of other molecules and dissolved gases.

Introduction

Homeopathy and homeopathic medicines are widespread and well accepted by many doctors, pharmacists and patients. It is officially recognised by health authorities and agencies authorities and at a political level in many parts of the world. However, they are also criticized and attacked by others. It is not my purpose to participate actively in a complex debate that includes not only scientific aspects but also sociological and economic components. My contribution will address only the arguments relying on the properties of water and only from the physical view. Consequently, at best, it is a physicist’s view of the role played by water in homeopathic solutions.

To clarify this statement, I think that it is useful to remember that medicine is not only a science but also an art. A good doctor takes into account not only the sickness itself but also the patient, his environment and his psychological aspects. As a consequence, the prescription of a medicine fortunately includes a large part of empiricism. The goal is to restore a ‘normal’ state. One must admit that the complete knowledge of all the parameters intervening in a real situation is totally illusory and that this situation is unlikely to change in the foreseeable future. Anyway, even when the active principles and biological receptors are well known and identified, the reactions of different patients are not the same. To circumvent these inherent difficulties the performance of drugs is established via statistical analysis of large numbers of cases with a randomised double-blind methodology which implicitly recognizes the hidden role of components which escape to the normal scientific analysis of ‘exact sciences’.

Modern pharmacological research is based on a detailed knowledge of physical and chemical interactions between drugs and living cells. At the confluence of Biophysics and Chemistry, a more detailed and precise picture of those interactions is steadily emerging. Still, many traditional medications and frequently-prescribed drugs are currently used without such detailed knowledge of their action. For them, it is either difficult or useless to define the exact ‘paths’ from medicine to biology, then to chemistry and physics.

Pure water and homeopathic drugs

Many traditional drugs, as for example those extracted from plants, are extensively used in medicine. In some cases one or more active principles have been identified but even in such cases the exact action is usually not well understood at the level of chemical reactions or physical interactions taking place within living organisms. This situation is very common but has never been a limitation to prescribing drugs that have shown their effectiveness through many years of practical use. Certainly, in other cases, the interactions are known in great detail leading to the synthesis of well-defined drugs with specific and well controlled applications. But we remain far from a comprehensive and detailed knowledge of the action of drugs on living organisms.

Homeopathic drugs fall, at least partially, into the first category. Their use has been validated by real or supposed successes, the frontier of the two being probably irrelevant from the point of view of the patient. But there is an essential difference between traditional or ‘natural’ medicine and homeopathy. The latter is much more recent and based in a quasi philosophical concept (similia similibus curentur) stated by Hahnemann, perhaps by analogy with the contemporary first studies of immunization. With modern science, it should, in due course, be possible to understand the mechanisms of action of natural substances and of homeopathic drugs. For natural substances the search for the active principles has been successful in some cases; in others, it has been simply assumed that they are present but the level of interest of the drug or available resources has not justified further studies.

With homeopathic drugs the situation is very different. Their method of preparation is based essentially on two steps: sequential dilution with ‘succussion’ or ‘dynamisation’ (vigorous turbulent shaking). A molecular view of the matter and a trivial calculation demonstrates that, often it is extremely improbable that even one molecule of the compound present in the original solution persists in a vial of the final medicine. The role of succussion is not obvious, even less the diverse standards of methods of preparation.

Under the pressure of criticism, the natural evolution of researchers interested in finding acceptable scientific justifications of homeopathy has been to go from purely medical concepts of effective therapy to chemistry and finally to fundamental physics. Ultimately, schematically, the answer: if there is ‘only’ water in homeopathic medicines, then the explanation of the therapeutic action must be in pure water, itself!

This intellectual evolution is a paradox. While for many drugs, the action is known at a biological, sometimes at a chemical, but almost never at a physical level (that of the structure and energies defined with atomic resolution); for homeopathy, the discussion jumped directly into this microscopic sub-molecular physics world. The mixture of the precise methodology characterizing research in physics and procedures deriving from pharmacology in research in homeopathy is striking. For example, several measurements of physical properties of diluted solutions have been done double-blinded. An extreme and provocative hypothesis is that water can retain a ‘memory’ of substances previously dissolved in it.¹

A critical analysis of several publications shows that several issues remain open to question. Schematically, one can distinguish the following:

(1) How different from pure water are highly diluted solutions? In other words, is the simple calculation of the number of molecules of the ‘active principle’ per unit volume of the solution sufficient to account for the composition of homeopathic medicines?

(2) If succussion is an essential step in the preparation of homeopathic medicines, what is exactly its role? How does it influence the dilution procedure?

(3) What is the behaviour of complex molecules (eg biopolymers, organic compounds, surfactants, etc.) during the dilution process?

A clear answer to these (and perhaps other) questions is a necessary and essential precondition to any study of ‘pure’ water. Indeed, the conditions of preparation and conservation of homeopathic medicines are far from respecting the simplest procedures required in physical studies of pure water.

Some issues should be controlled more systematically:

(1) Pure water is a very powerful solvent of many substances. For example, it dissolves and forms specific bonds with silica. In contact with the surface of quartz, water forms stable silanol groups (Si–O–H). With time, silica molecules and silicon atoms are solubilised and hydrated. The number of these ‘impurities’ is huge as compared with the calculated amount of molecules of the starting substance in most homeopathic medicines.

It may be useful to recall that the interaction of water with solid surfaces is so strong that studies of nucleation must be done with minute amounts of water kept in levitation, without any contact with solid surfaces. The interaction with solid surfaces is so important that if a supercooled liquid freezes, it must be heated up to temperatures higher than the melting point in order to be supercooled again. Less important for water than for other liquids (eg gallium), this effect is due to more favourable nucleation of the solid form at the solid surface.

Another point deserving investigation is the storage of homeopathic solutions over long periods of time. This procedure is totally incompatible with a chemical purity of water, even at a modest level.

(2) The main consequence of succussion is the insertion of substantial amounts of air from the environment where the procedure takes place. In a laboratory that is not a cleanroom (such as those used for example in electronics), the procedure brings into the solution not only the gases present in the atmosphere (oxygen, nitrogen, argon,…) but also dust particles, micro-droplets of water, etc. Recent studies² show that the properties of solutions are drastically modified when succussion is done under different atmospheres or at different pressures, a fact which should encourage further studies in this direction.

(3) Many substances, which contain pharmacologically active principles, are not soluble in water. Some are previously diluted in alcohol suggesting the presence of surfactant molecules that go spontaneously to interfaces such as the free surface, the interface between the solution and micro-droplets of gases and the interface with the vial. Again, several very promising and striking studies performed by the analysis of the thermoluminescence of frozen solutions open new and exciting perspectives.³

To summarize, it is striking that in publications concerning highly diluted solutions, chemical ‘purity’ is assumed, solely on the basis of a calculation based on the dilution procedure itself. In fact most of the samples studied are far from being ‘pure water’. It would be interesting to perform to a real analysis of the composition of the solutions with physical methods such as mass spectroscopy.

Properties of liquid water

As stated above, many experiments with homeopathic medicines assume the purity of the highly diluted solutions and attribute its therapeutic action to modifications of the structure and dynamics of the pure liquid itself due to the past presence of a solute.¹ Such a strong hypothesis would imply not only general or random changes but also a large variety of changes, specific to each solute. The main purpose of this paper is to recall that this hypothesis is totally incompatible with our present knowledge of liquid water.

Water, in all its forms (crystal, liquid, gas and amorphous forms) is certainly the most studied of all substances. All its properties have been measured with extremely high accuracy in very different conditions, including metastable states and ‘extreme’ conditions. This is due to the central role of water in many scientific domains in physics, chemistry, geophysics and, of course, biophysics. Essentially all known experimental techniques and computer simulations have been used to precise details of the behaviour of water at scales extending from hydrodynamics to the nuclear and electronic levels. In other words, water is not an unknown substance!

However, do we know ‘everything’ about water? Certainly not: several puzzling questions are open to discussion. In brief, the main open question about pure water concerns the supercooled (metastable) state (ie liquid water at temperatures below its freezing point) and its relation with different amorphous (glassy) states. The structure of liquid water, at atmospheric pressure, is not known in a large temperature range extending from the vicinity of the temperature of homogeneous nucleation of ice (−42 °C) down to the temperature of the glass transition (−140 °C). This problem is the object of debate and speculation mostly based in extrapolations of simulations of molecular dynamics performed by computer.^{[4] and [5]}

Another important domain of research is ‘confined water’, ie water occupying extremely small volumes, for example, in porous materials, in thin layers or in small pools formed at hydrophobic sites of bio-molecules. In this case, there is a large variety of situations that depend essentially on the nature of the substrate and on the relative importance of the number of molecules at the surface and in the bulk of the small volume. However, pure water at ambient conditions is well understood. Let us review some of its main properties that may be related to the subject of this paper.

Water is a simple molecule containing three atoms: one of oxygen and two of hydrogen strongly bound by covalent bonds. Because of the hybridisation of the molecular orbitals, the shape of the molecule is a V with the oxygen occupying the vertex of an angle of 104°; the O–H distance is almost exactly 0.1 nm. When two water molecules are sufficiently close, they orient one against the other to establish a chemical bond, called hydrogen bond. In this bond, one hydrogen atom is shared by two neighbouring molecules (Figure 1). The bonding energy is about 10 times larger than the kinetic energy but the bond is ‘fragile’ due the vibratory motions of the hydrogen atom particularly in the direction perpendicular to the line O–HO. It is possible to measure accurately the typical time for which the three atoms are aligned (the lifetime of hydrogen bonds): it is of the order of 0.9 ps (9×10⁻¹³ s) at room temperature.

Figure 1. Schematic representation of a hydrogen bond in water. The large circles represent two oxygen atoms of neighbouring molecules; the small circle is the hydrogen atom attached to the oxygen on the left hand side by a covalent bond. The length of the hydrogen bond is 0.18 nm.The hydrogen atom vibrates in all directions. Vibrations perpendicular to the bond are most likely to break the bond.

Because of its geometry, a water molecule can easily form four hydrogen bonds with four neighbouring molecules. This corresponds to the structural arrangement in common ice (I_h or hexagonal form). The angle of 104° is sufficiently close to the tetrahedral angle (109°) to impose this very open structure where each molecule is surrounded by four others at the apex of a tetrahedron (Figure 2). In liquid water this local geometry exists partly: on average a water molecule has 4.5 neighbours but this number decreases with decreasing temperature because the average number of ‘intact’ bonds increases. Incidentally, it is this decrease of the number of first neighbours that explains why the density of water decreases at low temperatures. At 4 °C, which is the temperature of maximum density, this effect compensates that of thermal expansion.

The average number of ‘intact’ bonds at a given moment is relatively high, although lower than in alcohols, for example. It is of the order of 60% which justifies seeing liquid water as a 3-dimensional network of hydrogen bonds, like a gel. But a gel with a life time of 1 picosecond (ps)! This means that in an ‘instantaneous picture’ of water structure (possible to obtain by computer simulations) one can identify local structures such as rings of 5, 6 or 7 molecules, regions with higher density of bonds than others, etc. All these structural properties can be identified by several techniques and correspond to thermodynamic properties. For example, the increase of isothermal compressibility observed at low temperatures is due to the enhancement of density fluctuations. It is very important to note that such fluctuations are not due to aggregation or formation of clusters. Hydrogen bonds form and break very rapidly generating short lived fluctuations of local density. In other words, even if at a given moment one can identify a region of higher density than the average, it will disappear after a very short time and will appear statistically in another place without any form of coherent motion such as would exist if a cluster was diffusing inside the liquid.

Historically, the first models of liquid water (due to WC Roentgen) represented liquid water as a mixture of an ideal liquid and small ice-like clusters. This model has been ruled out by many experiments. Among them, small angle X-ray scattering eliminates unambiguously any possibility of existence of clusters or aggregates in liquid water, even at very low temperatures.^{[6] and [7]}

Isolated or confined water molecules can have their mobility totally restricted. In such cases, the lifetime of a hydrogen bond can be infinite. This situation is frequent in proteins where hydrogen bonds with water can play a central role in protein structure. But, in these situations, water molecules don’t constitute a liquid. Consequently, it is worth emphasizing that to postulate the existence of stable structures in pure water is totally wrong. This is one of the limits imposed by the knowledge of the structure of water.

Aqueous solutions

In aqueous solutions, the situation is more diverse. Water can dissolve and mix with many substances in different proportions (salts, acids, various alcohols, sugars, and gases, etc). Both local structure and dynamic properties may be drastically modified. Two well known examples give an idea of the diversity of situations. Trehalose is a sugar that promotes the formation of glassy water even when extremely dilute. It is present in animals and plants which, because of this property, can survive very low temperatures. Other examples are aerogels of silica with a huge content of water, which can contain more than 95% water while remaining macroscopically solid.

Generally speaking, the inclusion of molecules or ions destroys local tetrahedral geometry. Depending on the nature of the compound, the molecules of water arrange in a large variety of local structures. For example, when a salt is dissolved in water, it is dissociated into two ions each of which is surrounded by a layer of hydration where the strong electrostatic interactions between the charge of the ion and the dipoles of water generate a mini-cluster (Figure 3). The life time of this cluster is 10 to 100 times longer than the lifetime of hydrogen bonds but is not infinite, because of the exchange between molecules of water in the hydration shell and those of the bulk.

Figure 3. Schematic representation of the arrangement around an anion (left) and a cation (right). In the first case the dipolar moment of the water molecules is directed towards the ion; in the opposite direction in the case of the anion. The screening of the electrical field of the ions is very efficient and the structure of water beyond the first hydration layer is almost not modified.

However, it is erroneous to believe that the electrical field generated by the ions extends over large distances. Actually, it is screened by the hydration layer. There is a large literature about the structure in hydration shells. The number of water molecules, distances and angles are known with great accuracy from neutron scattering experiments based on isotopic substitution.⁸

A very different situation concerns the solubility of hydrophobic atoms and molecules, such as methane or noble gases. In this case, water has tendency to form clathrate-like structures around the solute. A clathrate is a polyhedral structure; frequently a dodecahedron with pentagonal faces. This is a very stable structure, because the internal angle of the pentagon (104°) is equal to the internal angle, HOH, of the molecule. It forms a cage and the prisoner is the hydrophobic solute. The short lifetime of hydrogen bonds does not allow the formation of stable or long-lived clusters. Experiments simply detect, at best, a tendency to the formation of short lived planar pentagons.

Finally, it is interesting to consider situations in which stable aggregates are formed. The most interesting, including many industrial applications, are surfactants, which are molecules with a hydrophilic head (sometimes polar) and one or two hydrophobic tails. When dissolved in water in sufficiently large amount (above a critical micellar concentration, c.m.c.) they form structured clusters called micelles (Figure 4). The heads are at the external surface and the hydrophobic tails minimise the interaction energy with water inside the sphere. These structures are very stable. They persist essentially for ever, even if there are many exchanges of surfactant molecules between micelles, either by diffusion or as a result of collisions. Many structures of this type are known, of different sizes and shapes. Some are very important in biology or in pharmacy. For example, bi-layers of phospholipids mimic quite well some physical properties of biologic membranes, and vesicles are sometimes used as vectors or carriers of drugs.

In small quantities, surfactant molecules migrate to interfaces in geometries that minimise the interaction between the tails and water. Even at very low concentration they can modify substantially the surface tension of water. Whenever surfactant molecules are present in a substance, one must take into account their specific interactions with water.

Conclusion

To summarize this short overview, one can say that water is a ‘complex’ liquid with many fascinating, sometimes unique aspects. Except for some academic aspects concerning supercooled water, the structure of the liquid is well known. In particular, it is certain that:

(a) There are no water clusters in pure liquid water, but only density fluctuations.

(b) The longest life of any structure observed in liquid water is of the order of 1 ps (10⁻¹² s).

This is why any interpretation calling for ‘memory’ effects in pure water must be totally excluded.

In contrast, there is great variety of behaviour of solutes depending on many parameters. Even in small quantities, some solutes can modify substantially some properties of pure water. Special attention should be given to surfactants, sugars and polymeric substances. Since homeopathic medicines are prepared in ‘extremely high dilutions’ but following a procedure that does not produce necessarily extremely pure water, experiments should address the problem of the presence of minute amounts of solutes as has recently been done recently, with striking results.²

Otherwise, as stressed at the beginning, the advantages of homeopathic treatments should be taken at a medical level, which, after all, is the case for other drugs recognized for their remarkable although not yet explained effectiveness.

In the last decade, we have investigated from the physicochemical point of view, whether water prepared by the procedures of homeopathic medicine (leading inexorably to systems without any molecule different from the solvent) results in water different from the initial water?

The answer, unexpectedly, but strongly supported by many experimental results is positive. We used well-established physicochemical techniques: flux calorimetry, conductometry, pHmetry and galvanic cell electrodes potential. Unexpectedly the physicochemical parameters evolve in time.

The water solvent exhibits large changes in measurable physicochemical properties as a function of its history, the solute previously dissolved, and time. In particular we found evidence of two new phenomena, both totally unpredicted, in homeopathic dilutions: the presence of a maximum in the measured physicochemical parameters vs sample age, and their dependence on the volume in which the dilution is stored. These new experimental results strongly suggest the presence of an extended and ‘ordered’ dynamics involving liquid water molecules.

Introduction

The ‘Memory of Water’ is a journalistic expression, first used in the French newspaper Le Monde, after the publication in 1988 of Jacques Benveniste’s famous paper in the international scientific journal Nature.¹ In this paper he claimed, with biological experimental data, that ‘homeopathic dilutions’ of substances (ie so much diluted as to not contain any molecules of the substance initially diluted in it) are able to induce biological effects typical of the substance initially dissolved in it. The ‘memory of water’ is a synthesis of a still unexplained phenomenon. Recent scientific publications suggest some possible ways to experimentally validate the reality of a whole new class of physicochemical new phenomena concerning liquid water.²

It seems that it really is possible to obtain physicochemical information depending on the recent or remote ‘history’ of a water sample (in Prigogine’s terminology: breaking of the temporal symmetry), almost as in the better known case of magnetic materials (Prigogine would say: breaking of the spatial symmetry).³ The so-called memory of water, is connected to the capacity of this kind of solvent, a multi-variable complex system, to be influenced by very tiny perturbations, such as mechanical or electromagnetic actions, in such a way to move away from the initial equilibrium conditions, and this is increasingly established. The ‘memory of water’, in this sense, is comprehensible in the framework of the theory of Irreversible Processes Thermodynamics due to the Nobel Laureate for Chemistry (1977), Ilya Prigogine.³

In the last 10 years,^{[4], [5], [6], [7], [8], [9], [10], [11], [12] and [13]} our research group has investigated this problem from the point of view of the physicochemical properties of water when prepared following the procedures of homeopathic medicine preparation: iterative dilutions (of specific solutes of medical interest) followed by agitation (succussion). This method leads inexorably to systems without any molecule different from the solvent, in our case pure water.

Can the ‘new water’ thus obtained really be ‘different’ from the initial one? Answering this question was our challenge. The answer, unexpected but strongly supported by the experimental results, is affirmative. In the meantime, other research groups came to similar conclusions using different experimental models and other methodologies.^{[14], [15], [16], [17], [18], [19] and [20]} We also want to note here Giorgio Piccardi, the founder of the Italian physical-chemistry, and his pioneering work concerning fluctuating chemical reactions.^{[21], [22], [23] and [24]} A critical mass of experimental data² necessary to evidence a new class of physicochemical phenomena of the water has now been reached.

Methods

The experimental methodologies used for our investigations were chosen as the most efficient among the many tested. We list them, without entering into the technical details, but emphasising that they are well-established physicochemical methodologies: flux calorimetry, conductometry, pHmetry and galvanic cell electrode potential. The greatest difficulty of the preliminary work, which lasted for many years, was the selection of the most enlightening experimental methodologies and the establishment of optimal experimental conditions. It was also difficult to evaluate the contribution of the impurities released by the glassware, to the measured experimental values. In fact, the problem of impurities has been the principal objection probably due to the strong prejudice against the possibility that the procedures followed might really change the physicochemical nature of water.

Figure 1, Figure 2 and Figure 3 show that the presence of impurities released by the glassware makes a significant contribution to the physicochemical state of the dilutions, but it is not relevant in comparison with the unexpected contribution (much higher than the range of the experimental errors) of the auto-organisation process of the water molecules-the water is far from the thermodynamic equilibrium (see below) –and this auto-organization is triggered by external perturbations (such as iterative dilution and succussion).

Figure 1, Figure 2 and Figure 3 show: (i) how the contributions of impurity were taken into account; (ii) the major contribution of ‘something’ different from any possible substance of chemical origin. This is a preliminary result but it cleared misunderstandings from the experimental methodologies and allowed us to proceed to collect further information and insights on the nature of the ‘homeopathic dilutions’.^{[4], [5], [6], [7], [8], [9], [10], [11], [12] and [13]}

It is important to emphasise that, from the studies so far conducted, we cannot derive reproducible information concerning the influence of the different degrees of homeopathic dilution or the nature of the active principle (solute) on the measured physicochemical parameters. For this reason the experimental data reported in the figures are not given in terms of homeopathic dilutions or name of homeopathic medicine.

Ageing effects

A stimulating, and somewhat serendipitous, result very important in understanding the complex system under study, was that the physicochemical properties of the homeopathic solutions depend on time. The fact that the numerous experiences were performed over many years, naturally introduced the time parameter. The analysis of the experimental results vs the ‘arrow of time’ was of unexpected relevance,^{[7], [8], [9] and [10]} and led to the idea that the system under observation (homeopathic solution) is a closed system (able to exchange only energy with the external environment), far from thermodynamic equilibrium, which allows structures with a local order higher than the water around them to emerge from chaos (‘dissipative structures’).

Figure 4 and Figure 5 show that, unexpectedly, the investigated physicochemical parameter increases with time. In other words, ageing modifies the physicochemical nature of homeopathic solutions.

Figure 5. Excess specific conductivity, χ^E (μS cm⁻¹) (defined as the experimental difference between the experimental χ value and the contribution to this parameter by the presence of impurities (χ^chem) vs the samples age, t, for six homeopathic solutions. Each studied sample has its own peculiar χ^E vs time evolution but with overall similar behaviour: an increment of χ^E in time.

What is the interpretation of this newly-observed characteristic of the homeopathic solutions? Are we simply observing a system seeking an energetic minimum and a new equilibrium in a slow kinetic process or this is something totally different? From the data in Figure 4 and Figure 5 we deduce that the temporal variations of the reported parameters are very slow, because it takes many months to evidence them unambiguously. However, this temporal behaviour does not match the idea of a simple slow kinetic. In fact, following the reductio ad absurdum, if there exists an energetic minimum towards which the system could move, it would be impossible that in the time that water has existed, it has not reached this hypothetical minimum. Moreover for both parameters (specific conductivity and heat of mixing with alkaline solutions) an increase with time is observed. The correlation between the specific conductivity and the heat of mixing with alkaline solutions, shown in Figure 6 is linear; in other words, these two parameters have the same underlying cause. This result provoked us to investigate the nature of the mechanism able to increase simultaneously the electrical conductivity and the heat of mixing with alkaline solutions, after repeated dilutions and succussions. The descriptive model proposed below, although simple, is in agreement with the experimentally observed ageing effect.

An explanation of the electrical conductivity increasing after the preparation procedure and ageing may be based on the so-called ‘hopping mechanism’, proposed by C.J.T. Grotthuss (1806)²⁵ to explain the much higher mobility (about 5 times) of H⁺ and OH⁻ ions (always present in liquid water) in comparison with other ions of comparable ionic radius. If H₂O molecular clusters are present in the solution, bonded by hydrogen bonds, the hydrogen ions H⁺ colliding them experience the ‘hopping’ phenomenon (Figure 7): the water molecules catch an H⁺ ion at one end of the cluster (for the sake of simplicity considered linear) and release instantaneously another H⁺ ion at the other end of the cluster. The drift velocity under an electrical potential gradient (a measure of the conductivity) is much increased in comparison with that of ions which do not encounter H₂O molecular clusters. The greater the number of the clusters and/or their length, the higher the conductivity value. The correlation between the electrical conductivity and the heat of mixing with alkaline solutions is a consequence of H₂O clusters breaking, due to the pH variation (see Figure 8).

Figure 8. Schematic representation of the phenomenon of molecular clusters breaking, due to pH variation during the experimental procedure of determining the heat of mixing with hydroxide solutions (NaOH) 0.01 M (mol kg⁻¹ ) in a calorimetric cell. The experimental procedure consists of mixing a homeopathic dilution (that we suppose richer in H₂O molecular clusters than the ‘standard’ water solvent) with an alkaline solution. The pH variation seems to reflect breaking of hydrogen-bonded H₂O clusters, determining a transition order→disorder. This is experimentally evidenced by the increased heat of mixing compared to ‘normal’ water containing few molecular clusters.

The greater the number of the clusters and the larger their dimensions, the more is the measured thermal effect (Figure 8). These two experimental phenomena witness the same thing, both are sensitive to the number and/or dimensions of the clusters.

Let us return to the question: Are we measuring the presence of stable clusters seeking an energetic minimum? Or of unstable clusters consisting of dissipative auto-organised structures that are far from equilibrium and which remain or move away from equilibrium as a function of their ability to exchange energy with the external environment? We have already emphasised that the hypothesis of systems slowly evolving towards new equilibrium states is not compatible with our experimental findings. In particular, the hypothesis of systems evolving towards a minimum, even very slowly, contrasts with two new and very unexpected experimental phenomena characterising homeopathic dilutions:

(a) the presence of a maximum in the physicochemical parameters with sample age (Figure 9);

Each curve describes the temporal evolution of Arnica Montana (AM) samples in homeopathic dilutions prepared from the same mother tincture. There is no specific correlation between the χ^E behaviour and the degree of dilution (CH) of the samples.

(b) the dependence of the physicochemical parameters (apart from age) also on the volume in which the homeopathic dilution is stored (Figure 10).

Figure 10. Excess specific conductivity, χ^E, vs ageing volume, V. Each point represents the value of χ^E for each single dilution, experimentally determined at the same age. There is a very strong variation of the parameter, about one order of magnitude, for the systems aged in very small volumes. This volume dependence cannot be explained in the frame of the classical physico-chemistry.

Phenomenon (b) is absolutely anomalous and inexplicable in the current paradigm,¹³ it appears to be in sharp contradiction with the classical concept that an intensive physical quantity cannot depend on the volume.

The temporal evolution of the excess specific conductivity of four sample systems is shown in Figure 11. The samples were obtained as follows: a highly diluted aqueous system was divided into three smaller volumes at a certain ‘age’. As the figure shows, the excess specific conductivity (χ^E) behaviour across time of small volume samples is very different from that of larger volume samples. The larger volume sample does not display relevant modifications across time, while each new system of smaller volume evolves in a different way, with an overall common behaviour characterised by the presence of a maximum. This means that the evolution over time depends on the initial state (in this case: large or small volume), in a sense the systems have a ‘memory’ of the initial conditions.

Figure 11. Excess specific conductivity, χ^E, vs sample age, t. In this experiment, a homeopathic dilution of Arnica Montana was left to age for about 250 days in a volume of about 200 ml. At this time point 18 ml were removed and divided into three different vessels of equal shape, containing 10, 5 and 3 ml. The four obtained samples, 182, 10, 5 and 3 ml, were studied vs time. Their temporal evolution was dramatically influenced by the perturbation induced by the repartition into smaller volumes. In particular the higher volume of 182 ml did not experience particular temporal variations, while in the case of the smaller volumes, a large temporal evolution was observed, depending strongly on the starting point.

Another example of such ‘memory’ of the system is apparent in the experimental data displayed in Figure 12, which shows the temporal evolution of the excess specific conductivity for samples made from the same mother tincture diluted in double distilled water without succussion, in different dilution ratios.¹² Again, the system’s evolution in time is strongly conditioned by the initial conditions, with temporal variations characterised by very different maximum and slope values: past history influences the evolution of the ‘pure water’ system.

Figure 12. Excess specific conductivity, χ^E, vs age, t, of samples obtained by a simple dilution of the ‘mother tincture’ with double distilled water without succussion, in different dilution ratios (r). The volumes of the studied solutions were the same. The temporal evolution of the various systems, perturbed only by the simple dilution without succussion, is strongly dependent by the new starting state. In particular, the system with dilution 1:1, r=0.5 (final volume is twice the initial one) exhibits an initial χ^E value markedly lower than the solution from which it was obtained, then, in about 45 days, exhibiting χ^E values much higher with respect to the ‘mother tincture’, reaching a sharp maximum. In this case, the applied perturbation, determines a strongly different starting point, as well as different temporal evolution.

The apparent contradiction between the concept of intensive quantity, such as specific conductivity and heat of mixing, and the experimental evidence of dependence on volume may be solved by considering that, within the solutions there are molecular clusters consisting of water molecules connected by hydrogen-bonds, in far from equilibrium conditions. They can remain in, or move away, from their unstable equilibrium state, dissipating energy derived from the external environment: they are ‘dissipative structures’ as described by Prigogine.³

The spontaneous formation of molecular clusters in water is foreseen by the Coherent Quantum Electrodynamics (Coherent QED) without introducing the existence of hydrogen-bonds. This theoretical formulation, due to G. Preparata, E. Del Giudice, et al predicts the physicochemical properties of the water,^{[2], [26], [27], [28] and [29]} much better than other theories. The introduction of the ‘arrow of time’ into this theoretical framework should yield very interesting results.

Conclusion

We propose a simplified empirical model that in principle seems able to explain the unexpected dependence of the physicochemical parameters on the volumes used.

A first hypothesis to explain the experimental results is to suppose that the solutions, after strong agitation (succussion), enter a far from equilibrium state, remaining there or getting even farther by dissipating energy in the form and amount necessary to stay in the far from equilibrium state. Then, assuming that radiant energy is exchanged, we can further suppose that, for a given flux of dissipated energy (W cm⁻²), the same number of dissipative structures would be formed, even if contained in different volumes. In this frame, on average, at any given age, small volumes of water will contain a higher ‘concentration’ of dissipative structures in comparison with larger volumes (Figure 13). The physicochemical parameters electrical conductivity and heat of mixing are in fact functions of the number, size and shape of the dissipative structures.

Figure 13. Schematic representation of a possible temporal evolution of a homeopathic solution, showing a variation of intensive quantities such as χ^E (μS cm⁻¹) and Q^E_mix (J kg⁻¹) vs the storage volume. At the time zero, the two vessels, of equal shape and volume, contain two identical homeopathic dilutions (same age, same active principle, same CH dilution) with no experimentally measurable effects determined by dissipative structures, because of their small number (Figure 13a). Assuming the same formation efficiency (and/or increase in size) for the dissipative structures in the two systems (small volume and large volume), with the same conditions of energetic flux, the number and/or size of the dissipative structures is almost the same in the two containers, at any given time (Figure 13b and c). So, when dissipative structures are numerically increasing, their concentration is much higher in the small volume than in the large one. Consequently, intensive quantities such as those measured, χ^E (μS cm⁻¹) and Q^E_mix (J kg⁻¹), sensitive to the structure concentration, will show a temporal behaviour dependent on the volume.

We conclude the following:

• the parameters whose values results ‘in excess’ (in general: variable with the history of the solvent in time) are correlated with the dynamics of supermolecular (mesoscopic) structures in the water solvent;

• the temporal evolution of the parameters is not connected to the tendency to seek an energetic minimum;

• an empirical interpretation, consistent with all current experimental data, is based on the presence of dissipative structures.

Succussion may be the trigger for the spontaneous formation of dissipative structures, that is the emergence of new dynamics. The temporal evolution may be connected to the variation of the number, dimension or the shape of the dissipative structures. It is well known, in Thermodynamics of Irreversible Processes, that the temporal evolution of the systems depends on the initial conditions and on the way the systems evolve.Much new experimental data converge towards the validation of the statement that water, at least in the context of the procedure of the homeopathic medicine production, really has a ‘memory’. That is to say: the water solvent shows experimentally measurable physicochemical properties that vary as a function of the ‘lived path’, of the solute previously dissolved, and of elapsed time.

Without doubt liquid water has an extended and ‘ordered’ dynamics involving the whole body of the liquid. It is much more complex than the normal idea of a banal and chaotic cluster of ‘molecular balls’.

Low-temperature thermoluminescence has been used in attempt to understand the particular structure of ultra high dilutions. Samples are activated by irradiation after freezing at the temperature of liquid nitrogen (77°K). Experimental results show that, in the course of rewarming, the thermoluminescent glow is susbtantially different between dilutions of different substances. It is suggested that the dispersed gas phase might play a role in this process.

Introduction

No chemical is more common on earth than water: it covers 75% of the earth’s surface with a total mass of 1.4 billion megatons. A very simple molecule, with one central, negatively charged, oxygen atom and two positively charged hydrogen atoms 0.1 nm apart at an angle of 104°¹ water is, nevertheless, a most atypical compound. In the liquid state, it is an abnormal fluid which should be a gas by comparison with other similar chemicals. Among other unusual properties, it increases in volume when crystallizing into solid ice at 0°C and boils at 100°C: both these temperatures are abnormally high for a substance which is neither a metal nor an ionic compound. Its dielectric constant as well as its increasing fluidity with rising pressure is equally odd.

In fact, liquid water is not a simple association of independent molecules; the molecules are actively interconnected by hydrogen bonds^{[2] and [3]}. Liquid water is, indeed, a structured fluid which behaves as a polymer. In an ever-moving universe, individual water molecules link to each other, most often in tetrahedral geometry, building evanescent clusters which are continuously formed and dissociated again at random in a pico-second timeframe. When an ionic compound is dissolved in H₂O, each ion is immediately surrounded by a spherical shell of water molecules so intensely that, should the concentration of the solute be high enough (over about 10%) all the shells come into contact and there is no more truly liquid water.

It can, thus, be understood that, in the preparation of an homeopathic medicine, any compound dispersed in water gives rise, from the outset, to a specific structure. When successive dilutions are made the violent turbulence created in the liquid by each succussion, helps to both maintain and possibly spread the original structure despite, progressively, the solute content of the dilution dropping by a factor of 100 with each centesimal step. However, Brownian motion is still very active and these ‘remnant structures’ fade away and reconstitute continuously. In other terms, we could say that homeopathic dilutions are ‘statistically structured’ and could remain so beyond the Avogadro number. Succussion appears to be an essential part of the overall process.

Research objective

It is easy to understand why, based upon this succession of dilutions–succussions, many scientists believe that eventually—and definitely beyond the Avogadro number—the resulting ‘solutions’ are no more than the dilution fluid itself. However, numerous physiological and clinical tests have demonstrated for decades, since Hahnemann himself, that this is not the case. Our research objective has been to try to demonstrate that the high dilutions are physically different from the diluent and have, indeed, an ‘individual personality’.

Method

Since any investigation is always difficult in an highly dynamic system we assumed that, should some specific ‘patterns’ exist in the liquid dilution they might be fixed when it is frozen giving rise to specific defects in the crystal lattice of ice, which could be investigated by appropriate means.

To perform this type of studies we selected low-temperature thermoluminescence. This technique, which is well known for archaeological and geological dating,⁴ has been adapted by us to low temperatures⁵ and described in detail in previous publications.^{[6] and [7]} I will here only summarize here its main features.

A 1 cc sample of the dilution under investigation is placed in an aluminum cup and frozen down to liquid nitrogen temperature (−196°C=77°K) following a well defined multi-step process. The frozen 1 mm thick ice disk is then ‘activated’ by radiation (Gamma rays, X-rays or electron beams) which displace electrons from their quantum ground states. The sample is then rewarmed at constant rate (3°C/min) from 77°K to melting point. During that process the electrons, powered by ‘thermal activation’ leave their respective traps and recombine with the empty quantum ‘holes’ releasing their ‘activation energy’ in the form of light as they do so. This light is the thermoluminescent glow that we record.

The analysis of the emitted light shows two main peaks around 120 and 166°K for deuterium oxide and 115 and 162°K for H₂O.⁵ Their relative intensity and shape vary both with the radiation dose and also with the nature of the radiant beam. In particular peak 2 displays a complex structure which can be resolved in a set of individual components by a deconvolution technique.^{[8] and [9]} It is assumed that the ‘defects’ present in the ice crystalline lattice are active luminescent centers, hence that thermoluminescence might be an appropriate tool to study the ‘image’ of the initial liquid samples.

Results

Thermoluminescence is known to be a very sensitive technique and has been used to identify trace compounds. For example see Figure 1, the thermoluminescence emissions of very dilute alumina colloidal sols which show major differences between the 10⁻⁸ g/ml, 10⁻⁹ and 10⁻¹⁰ g/ml solutions.

For homeopathic high dilutions we use deuterium oxide (D₂O, heavy water) as the solute since the signal is 50 times more intense than that of H₂O, due to the more rigid nature of the two ‘arms’ of the molecule. As diluted substances we selected two ionic compounds: sodium chloride (NaCl) and lithium chloride (LiCl). The latter was selected because, like urea and ethanol, it is known to impact on and suppress the hydrogen bonds¹⁰ which are thought to be involved into the high temperature peak (ca 166°K) of the thermoluminescence glow.⁶ Figure 2 shows that the curves recorded for successive dilutions of LiCl (3c, 5c, 7c, 9c) prepared by the classical Hahnemannian method and following the French Homeopathic Pharmacopoeia (150 strokes of 2 cm amplitude in 7.5 s, delivered by mechanical succussion machine) are substantially different.

Subsequently, since it appeared that we had a reliable tool for assessing the dilutions we applied the same method to ultra-high dilutions beyond Avogadro’s number.⁶ Figure 3 gives the results and shows evidence that the ‘signature’ peak of LiCl 15c is substantially lower than that of NaCl 15c and lower than succussed pure D₂O. This demonstrates that: ultra-high dilutions are different from their dilution fluid.

The high temperature components of the glow (ca 166°K) is linked to the hydrogen bond network. These results have been recently confirmed by another research group.¹¹

In recent and still unpublished experiments we found the same type of ‘scaling’ between increasing dilutions of other compounds, among which potassium dichromate looks particularly interesting.¹²

New prospects

As I said above, in the homeopathic preparation scheme, succussion is an important component of the preparation process of homeopathic medicines, releasing considerable energy in the fluid. In view of this I became interested in recent research on the role of ‘nanobubbles’ in water.¹³ Part of the ‘message’ transferred from one dilution step to the next one might be linked to the nanobubbles created into the liquid by the successive strong mechanical agitation which creates turbulence.

To investigate this, we built special equipment to perform dynamization in gas atmosphere or vacuum. We dynamize the dilution at room temperature (20°C) under a moderate vacuum (2337 Pa=24 mbar) which corresponds to the saturated water vapour pressure at 20°C. Time to reach vacuum is approximately 20 seconds. Dynamization is 150 strokes in 7.5 sec followed by stabilization under reduced pressure for 3 minute. The vacuum is broken reverting to atmospheric pressure in 20 seconds. Figure 4 gives preliminary results which show that the gas-phase seems to play a major role in the ‘personalization’ of the dilutions. Bearing in mind that the number of nanobubbles created into the fluid is of the order of billions (which represents a very large ‘contact’ surface with the surrounding liquid) and that, due to their size, they may remain stable and undisturbed in the dilution for months or even much longer, this might open some new perspectives on our understanding of the homeopathic preparation process.

The time to reach vacuum is approximately 20 seconds, we use our standard dynamization: 150 strokes of approximately 2 cm amplitude in 7.5 sec, followed by stabilization under reduced pressure for 3 minutes. The vacuum is then broken, reverting to atmospheric pressure in approximately 20 seconds.

Abstract

The key stumbling block to serious consideration of homeopathy is the presumed “implausibility” of biological activity for homeopathic medicines in which the source material is diluted past Avogadro’s number of molecules. Such an argument relies heavily on the assumptions of elementary chemistry (and biochemistry), in which the material composition of a solution, (dilution factors and ligand–receptor interactions), is the essential consideration.

In contrast, materials science focuses on the three-dimensional complex network structure of the condensed phase of water itself, rather than the original solute molecules. The nanoheterogenous structure of water can be determined by interactive phenomena such as epitaxy (the transmission of structural information from the surface of one material to another without the transfer of any matter), temperature–pressure processes during succussion, and formation of colloidal nanobubbles containing gaseous inclusions of oxygen, nitrogen, carbon dioxide, and possibly the remedy source material.

Preliminary data obtained using Raman and Ultra-Violet–Visible (UV–VIS) spectroscopy illustrate the ability to distinguish two different homeopathic medicines (Nux vomica and Natrum muriaticum) from one another and to differentiate, within a given medicine, the 6c, 12c, and 30c potencies. Materials science concepts and experimental tools offer a new approach to contemporary science, for making significant advances in the basic science studies of homeopathic medicines.

Introduction

Overview

The key stumbling block to serious consideration of homeopathy is the alleged “implausibility” of biological activity for homeopathic medicines in which the source material is diluted past Avogadro’s number of molecules (6×10²³), because the remedy must be identical to the solvent. Negative studies of homeopathy are self-evidently correct from the skeptics’ perspective, because of this error.¹ The implausibility argument leads skeptics to ignore or reject positive evidence from numerous basic science, preclinical, and clinical studies showing effects of homeopathic medicines different from controls, in vitro and in living systems.² On the other hand, proponents predictably reject the negative and focus on positive studies, often uncertain how to address the black box nature of homeopathic medicines. Both skeptics and proponents of homeopathy have generally overlooked a large body of literature in the materials science field that could help resolve this impasse with systematic data.³

Thoroughly, established materials science concepts and research data render the implausibility hypothesis for homeopathy irrelevant. One example suffices. Diamond is the hardest material in nature and graphite among the softest. Yet they can be inter-converted with zero change of composition in microseconds.

The available studies enable significant hypothesis-driven advances in the rigorous study of the nature of homeopathic medicines. The purpose of this paper is to outline the key aspects of materials science considerations in developing experimental models for understanding homeopathic medicines and to summarize preliminary findings from hypothesis-driven studies in our laboratory on clinically known polychrests such as Nux vomica (Nux vom) and Natrum muriaticum (Nat mur).

Materials Science Models for homeopathic medicine

Chemists and medical scientists largely continue to focus reductionistically on the presence or absence of specific molecular species present in water vapor or liquid water without consideration of the ways in which these species are organized in space. From a chemical perspective, the dilution aspects of remedy preparation are the key issue, because of a lack of source molecules for potencies at or beyond 12c or 24c× (10⁻²⁴ dilution). Even when chemists focus on water itself, they emphasize the fleeting stability of hydrogen bonding between given water molecules,⁴ rather than the larger complex structural formations of water or the weaker forces that may favor formation of stable oligomeric and polymeric structures, involving the collective organization of many different water molecules within the condensed liquid phase.

In contrast, materials scientists focus on the organizational network arrangement of the water structures in three-dimensional (3-D) space. In a recent paper, Roy et al.³ presented the detailed technical aspects of the materials science argument concerning ultradilute sols including homeopathic medicines at length. For materials scientists, the succussion aspects of remedy preparation are the key consideration. Temperature and pressure can modify such water structures, leading to nanoheterogeneity of larger structures of water molecule “clusters” within liquid water. Succussion introduces intense turbulence and changes in pressure in any solution,⁵ as well as leading to the formation of nanobubbles in solution.

In brief, the plausibility argument for homeopathy is that liquid water, the primary solvent for source materials in which homeopathic medicines are made, is itself an anomalous substance and has many very different structures. As part of the natural nanoheterogeneity of water structure per se (as contrasted with its composition or the presence of solute molecules), processes such as epitaxy, pressure changes during succussion, formation of colloidal nanobubbles containing gaseous inclusions of oxygen, nitrogen, carbon dioxide, and possibly the remedy source material, and electromagnetic field effects play a role in altering water structure. Previous work by Elia and Niccoli⁶ and Rey,⁷ using different technical methods, respectively, to release heat or light from homeopathic medicines in potency, point to the ability to disrupt what appears to be order or structure in remedy solutions as compared with remedy-free control solvents.

In terms of nanoheterogeneity, water can take on many possible oligomeric and polymeric structures, ie, form complex networks of water molecules in 3-D space, held together by various forces that include not only hydrogen bonds (relatively strong), but also van der Waals forces (much weaker). Even if specific molecules or small molecular complexes leave their places in the network, other water structure complexes can take their places within the network structure itself, thereby maintaining the overall nanostructures within the solution, in part via configurational entropy or electromagnetic forces maintaining organizational stability of the network.⁸

Notably, research in the field of complex systems and network science has shown that, within a highly complex network, loss or disruption of a given member or node, which is a point of interconnection with other members of the network (eg. a water molecule or small complex of water molecules) does not destroy or significantly disrupt the overall network organization.^{[9] and [10]} With complexity in liquid water as a whole comes the capacity for overall stability that is not possible in the simpler organizational structures of water on which chemists usually focus.

Epitaxy is the transfer of information, not material, from the surface of one material, usually solid, to another, usually liquid¹¹. The substrate (eg. remedy source material) acts as a seed crystal for the formation of the structure in the recipient surface material (eg. network organization of water structures). Semi-conductor manufacturing often utilizes epitaxial growth to generate specific types of microtransistors and integrated circuitry. In addition to the original source material that uniquely contributes to remedy preparation, deliberate additives in homeopathic medicines, such as ethanol, and/or possible contaminants from succussion, such as silicates from glass container walls, may also stabilize the water molecule structures with their own epitaxial capabilities. Thus, epitaxy can interact with temperature–pressure factors to create unique patterns of information without the transfer of material.

In terms of “seeding” formation of informational structures within water, initial empirical observations on homeopathic medicines suggest that the passage of time between the original remedy preparation and the testing procedures can alter experimental findings. In calorimetric and thermoluminescence studies on homeopathic medicines, the time factor contributes to differences in the magnitude and even the direction of the divergence between remedy and control solutions.^{[4] and [12]} Overall, the behavior of homeopathic medicine liquids in terms of their structural properties in the basic science literature exhibits a somewhat unpredictable, self-organizing quality.

As additional data emerge, these lines of research may facilitate advances in understanding the nature and mechanisms of variability in clinical responsivity to homeopathic medicines.^{[13] and [14]} Water is an hub molecule (a highly interconnected and influential molecule) in most of the biochemical reactions in the body.¹⁵ In a more speculative but testable vein, seeding informational changes in body water at global and local levels¹⁶ of scale could be one way in which homeopathic medicines interface with patients to induce patterns of system-wide and local healing responses.¹³

Implications of materials science models for basic science research methods in homeopathy

Materials science models for the nature of homeopathic medicines leads to more rational selection of specific methodologies for basic science studies. For example, many earlier studies of homeopathic medicines relied on nuclear magnetic resonance (NMR) techniques.^{[17] and [18]} However, NMR spectroscopy provides information on structure of individual atoms in a pure molecule better than on complex networks of molecules. Technically, NMR also requires addition of substances to prepare a liquid for testing. The necessity of adding factors in the process of making observations can introduce unintended contaminants into the measurement process.

In contrast, the light scattering technologies of Raman spectroscopy and Fourier transform (FT) infra-red (IR) spectroscopy permit examination of remedy samples without fixatives or other potential contaminants. Furthermore, Raman and infra-red spectroscopic techniques allow the co-operative nature of structural differences to be detected. Recent studies¹⁹ of microscopic dynamics of hydrogen bonded liquids indicate the existence of highly directional H-bonds, whose energy value normally range between 8 and 25 kJ mol⁻¹ induces different chemical–physical properties and different local environments. As the mean lifetime of H-bonds is in the picosecond timescale, such structures are considered as transient species in dynamic equilibrium.

Our recent work has established the importance of the structure of water on its properties,³ we examined the structures of many water and alcohol-based homeopathic remedies. The results show that such materials can be easily distinguished from the pure solvent, and from each other, by the use of UV–VIS (ultraviolet–visual) and Raman spectroscopy, but Fourier transformed infra red (FTIR) spectroscopy proved insensitive to these differences. This opens up a whole new field of endeavor for inorganic materials scientists interested in developing a scientific basis for the efficacy of homeopathic remedies. The assumption of this study is that the joint employment of the two methodologies: optical spectroscopic tools and electronic microscopic tools can furnish a closer reference picture for the comprehension of the structural changes in the liquid phase besides providing an independent understanding on the role of the ‘active ingredient’ in a homeopathic medicine.

Also we believe that our very preliminary efforts in using cryo-scanning electron microscopy (cryo-SEM) and cryo-transmission electron microscopy (cryo-TEM) may eventually possibly provide definitive evidence of the presence, and the effects, of nanobubbles on homeopathic medicine studies.

Preliminary studies of homeopathic medicines using Raman and infrared spectroscopy

Method

A Food and Drug Administration-regulated homeopathic pharmacy (Hahnemann Laboratories, San Rafel, CA) prepared samples of two different test solutions in 16 ounce (450g), clear glass bottles [Type I borosilicate glass] previously annealed at temperatures between 600–700 °C for 15 minutes. One of the solutions, Nat mur (mineral: Sodium Chloride) and the other Nux vom (plant remedy, purchased as tincture from Boiron) were diluted by the standard Hahnemannian techniques in 95% ethanol and succussed: a 30c potency is diluted (1/100)³⁰ or 10⁻⁶⁰ from the original material. They were hand-succussed by trained experts [www.hahnemannlabs.com/preparation.html] 30×20=600 times during the manufacturing process. Each bottle was coded with an unique number, the bottles were shipped together by overnight courier in the same box, with temperature sensor.

We have used UV–VIS, IR, FTIR, and Raman spectroscopy for the bulk “liquid” which in most cases is either water or a mixture of water and ethanol (95% ethanol). UV–VIS spectroscopy and Raman spectroscopy proved to be useful tools to investigate the subtle but significant changes in the structural parameters in both water and alcohol based remedies. (For details refer to 20). While other techniques such as freezing point depression; acoustic loss spectroscopy, ellipsometry, viscosity, surface tension, have been explored and will eventually be used in depth to measure entirely different properties, we report here our experience with the major spectroscopic techniques which are widely available.

(c) Raman spectrophotometer: Inphotonics, Model RS2000-3b-785, using an InPhotonics fiber optic immersion probe.

Results

Nearly 200 runs were made to calibrate every step in the experimental configurations and procedures used for the different instruments. In the dual beam UV–VIS, the many experimental options are all tested separately to ensure that any differences within the data obtained on our samples are well above the instrument noise measured in the calibration run data. The data are obtained largely at different times scales by different individuals gave consistent results. We note that at very low signal levels, instrument noise coupled with artificial computer generated sensitivity can produce data that are not reliable. Hence, we operate the instruments in the sensitivity ranges in which we sacrifice some precision for reproducibility. In the Raman spectrometer, careful attention is paid to the positioning of the probe within the sample container, and stray light is eliminated by turning off all the room lights whenever data are being collected. Details of this work are published elsewhere.²¹

One of the objectives in undertaking this work is to examine evidence which would suggest reliability of physical properties, assuming structural changes in solvents, especially in ultradilute and dilute sols, an excellent example of the class of materials being homeopathic remedies. For our study, we chose to study Natrum muriaticum and Nux vomica, obtained from Hahnemann Laboratories. Both Nat mur and Nux vom are prepared in 95% ethanol. Three types of analyses are presented:

(a) Comparison of specific homeopathic remedies with different potencies [Nat mur 6c, 12c, 30c, and Nux vom 6c, 12c, 30c].

(b) Comparison between two different remedies of the same potency [Nat mur vs Nux vom 6c, 12c, and 30c].

(c) Comparison of the two homeopathic remedies with unsuccussed and succussed plain ethanol.

Figure 1 shows a comparison of Nux vom and Nat mur, 6c, 12c and 30c, showing representative UV-spectra demonstrating the differences between the remedies. In Figure 2 (a), and (b) we show the envelope of differences within a series of 10 preparations of each remedy of Nat mur and Nux vom. The spectra show clear differences in the same potency of an individual remedy for both Nat mur and Nux vom.

A comparison was also made between the unsuccussed ethanol and the Nat mur and Nux vom samples as shown in Figure 3. The Roy et al paper³, on “structure of water” clearly evidence the role of succussion besides epitaxy and other temperature effects, on the structure of liquids. Under the “normal” succussing procedures, it can be argued that very considerable pressures (of the order of 10 kbar) could be generated as a result of the shaking. Dachille and Roy²² showed that mere grinding in a mortar and pestle gives rise to high pressures up to 20 kbar, and the figures for force per unit area are strongly dependent on the size of the water particles and the velocity of the shaking. By analogy with similar liquids, such as ethanol, there will be many different structures of water formed both by the pressures generated in succussing in some combination with the epitaxy on any additives.

It may be noted from Figure 3 that the absorption spectra for unsuccussed ethanol is significantly different from: (a) the succussed ethanol and (b) succussed homeopathic remedies, Nat mur and Nux vom. The difference may be attributed to the variation in intra and inter-molecular association of ethanol and water and the generation of both transient and stable nanobubbles. The work of Tyrrell and Attard at Australian National University has proved beyond any doubt that nanobubbles do exist and persist.²³ FTIR Spectra (not shown here) from all the samples of Nat mur and Nux vom overlap neatly, clearly signifying that FTIR is not the most sensitive technique for analyzing the subtle structural differences in these types of samples.

Comparison of homeopathic remedies with different potencies using Raman spectroscopy is done on the two sets of homeopathic remedies: Nat mur and Nux vom. From the spectra shown in Figure 4, a clear distinction in the Raman active modes is noted between the two different remedies as well as among the different potencies of the same remedy. A clear distinction is shown in the spectral peaks from the different potencies, peak positions identified as (a), (b), (c), (d) and (e) in the Raman spectra of Nat mur samples show significant structural changes. While the existence of distinct structural changes in Nat mur and Nux vom remedies is clear from the Raman spectra, significant structural changes are also noted in the spectra of Nux vom between the different potencies, 6, 12 and 30c, peak positions are identified as (a), (b), (c), and (d) in Figure 4b. Further, since all the homeopathic medicines were prepared in 95% ethanol, we analyzed the Raman spectra of unsuccussed and succussed ethanol shown in Figure 5. Note that 6c potency of the succussed ethanol show distinct structural variations.

Conclusions

Materials science provides a conceptual and empirical foundation for future research on the nature of all the dilute sols including homeopathic medicines in the physical plane. Processes such as epitaxy, temperature-pressure induced changes in water structure, and nanobubble formation offer testable hypotheses for understanding homeopathic medicines. Although hypotheses regarding seemingly unmeasurable “subtle energies”²⁴ and/or macro-entanglement phenomena^{[25] and [26]} may help explain the fuller nature of homeopathic medicines, the available evidence also suggests that homeopathic medicines can exhibit qualitatively and quantitatively different structural properties from those of unsuccussed or succussed solvents. Even in the case of subtle energies, initial findings indicate the possibility of measuring changes in liquid structure properties from the materials science perspective.^{[27] and [28]}

The convergence of data from different experimental models suggests that it is feasible to study the nature of homeopathic medicines using available basic science tools, notably here, Raman spectroscopy and ultraviolet–visual absorption (UV–VIS) spectroscopy. Reproducibility of findings is feasible within the same Raman equipment, but, not across different Raman spectrophotometers from the same manufacturer at different geographic locations, even for materials other than homeopathic medicines. Fourier transform infrared (FT-IR) spectroscopy cannot differentiate different homeopathic medicines or different potencies of the same remedy from one another. Transmission and structural electron microscopy are promising options for testing the nanobubble hypothesis.

Finally, the materials science perspective provides a possible translational bridge from the emerging complex systems/network science models for clinical responses to homeopathic treatment^{[5], [12], [13], [29], [30], [31] and [32]} to another level of organizational scale, ie, the network structure of the homeopathic medicines themselves. Given the holistic quality of clinical diagnosis and remedy selection in homeopathy, the articulation of holistic (complex network) rather than reductionistic models for both the clinical healing process and the nature of homeopathic medicines is heuristically appealing.

We discovered a previously unknown phenomenon in liquid water, which develops over time when water is left to stand undisturbed, and which made precise gravimetric measurement impossible. We term this property autothixotropy (weak gel-like behaviour developing spontaneously over time) and propose a possible explanation.

The results of quantitative measurements, performed by two different methods, are presented. We also report the newly discovered phenomenon of autothixotropy-hysteresis and describe the dependence of autothixotropy on the degree of molecular translative freedom. A very important conclusion is that the presence of very low concentration of salt ions, these phenomena do not occur in deionized water. Salt ions may be the determinative condition for the occurrence of the phenomena.

‘Autothixotropy’ of water

Qualitative laboratory observations

From 1978 to 1986 we performed a series of measurements^{[1] and [2]} to verify the gravitational law in fluids as deduced by Horák.³ Originally, in 1978 we observed a peculiar phenomenon in the measurements which compelled us to use another method. A series of experiments focusing on this phenomenon were conducted. In the Department of Physics in University of Hradec Králové, an experimental apparatus was constructed (Figure 1) to observe the phenomenon.⁴

Figure 1. Experimental setup for the static method of measurement.

After objects immersed in the water have been at rest for one or more days, seven qualitatively different phenomena are observed, using this method:

(1) When the hanger is rotated by a certain angle, the plate immersed in the water remains in practically the same position, in spite of the twisting tension arising in the thin filament. When a certain critical angle is reached, the plate will rotate, relatively quickly, to a new neutral position determined by the hanger, to the position where the filament is relaxed (ie with no torsion). If the rotation of the hanger is interrupted before the critical angle is reached, a ‘creep’ toward a new neutral position is observed over some days or weeks. When a smooth-surfaced cylinder, capable of rotating around its own axis, is used instead of the plate, these phenomena are not observed.

(2) Another, weaker phenomenon, is also observed: an immediate rotation of the plate in the direction of the rotation of the hanger; nevertheless, the angle of the immediate rotation is one or two orders of magnitude less than the angle in phenomenon (1).

(3) The critical angle of rotation in phenomenon (1) is dependent on the period of time the water has been at rest. This angle increases with time, starting from virtually zero. (The critical angle can reach values of several tens of degrees)

(4) If the plate is only partially immersed, the critical angle is significantly greater than when it is immersed completely.

(5) In the case of partial immersion, the phenomenon analogous to (2) is much more prominent. Phenomena (4) and (5) are time-dependent as described in (3) despite the time-invariance of the surface tension which we also tested.

(6) If the water is stirred after having been at rest for several days, then, when again at rest, the critical angle increases from zero more quickly than when new ‘fresh’ water is used.

(7) The critical angle is significantly increased and the phenomenon appears earlier if the (distilled) water is boiled (thus substantially deaerated) before the experiment is started.

Our first attempts to carry out quantitative experiments with any acceptable precision were not successful. This was due to a too large dispersion of the measured values; much more sophisticated laboratory equipment than we could acquire, as well as stricter measurement conditions than those we could guarantee, were necessary. In spite of many problems, such experiments have since been performed,⁵ and showed that the phenomena did not appear in deionized water. In accordance with the generally accepted terminology, we named this complex of phenomena autothixotropy of water.

Proposed explanation

In terms of explanation, a hypothesis based on ‘ephemeral polymerisation’ of water seems plausible. The existence of such a weak polymerisation was suspected decades ago, both defended and denied by experts. If ephemeral polymerisation of water is the cause of the observed phenomena, it suggests that water molecules are establishing chains or a network; first as minute complexes and thereafter combining successively with one another. The structure then becomes increasingly dense while oscillating at a certain amplitude on a scale of molecules. Such a structure will be relatively fragile, susceptible to differences in the concentration of materials dissolved in water, at different points inside the vessel. Brownian motion can be observed in the case of a conglomerate of molecules having a non-polar character, owing to collisions with molecules of water oscillating in the established network. Weak stirring of ‘old’ water seems to leave parts of the network intact, making the subsequent ‘dipole polymerisation’ quicker than it would be in the ‘fresh’ (ie well stirred) water. Further, the structure has some elasticity. If the water is boiled, no dissolved air (gases) disturb either on the developing process or integrity of the structures; consequently, the phenomenon appears earlier and is more pronounced.

One can expect that the described water structure can be important in biophysics for description and influence on cell characteristics (see eg Pollack⁶). Our observations are consistent with the recently published results of Wernet et al.⁷

Autothixotropy and molecular translative freedom

The autothixotropy of water depends, among other things, on the degree of freedom of the translative motion of its molecules. The freedom is limited close to the boundary between the water and some other environment, eg a solid body or the atmosphere over the surface of the water. The freedom of the molecular motion is then limited relatively very deep into the body of the water, perhaps on the scale of several hundred molecular layers or more. The limited degree of freedom, depending on the number of free space-dimensions being less than three, appears as follows:

(1) When the free motion is limited to two space-dimensions ie more or less to a plane, one can find its relevant manifestation in phenomena (4) and (5) described above.

(2) If a thin capillary tube were used, the free molecular transitive motion would be limited in practice to just one dimension. This explains the phenomenon of polywater, observed decades ago, and claimed to be a sensational discovery, but which soon proved to be false.

(3) When the transitive freedom is limited in all possible directions, ie in all three space-dimensions, the manifestation of the autothixotropy must logically become very prominent and influential. Such a situation occurs in small cellular spaces and possibly significantly influences, or even determines, the rigidity of the cytoskeleton. It is presumed, however, that the cells aresufficiently static in relevance to the autothixotropy.

Salt ions

Currently two diametrically sets different of results supported by serious observations exist concerning the duration of structures in liquid water. According to one⁸, molecular clusters in water have a duration of less than one hundred femtoseconds. According to ours, clusters grow to webs on a time scale of days. Since these webs do not arise in deionized water, we believe the purity of the water to be a decisive factor. The distilled water we used was not perfectly pure and could have been significantly contaminated by salt ions, even if only to a very minute degree. From a comparison of experiments with distilled water and deionized distilled water, it is possible to deduce that cores of macroscopic clusters of water molecules are salt ions contained in water.

Moral: If two different observations seem to be mutually incompatible within the frame of an established theory, the most probable explanation is not that one of the observations is wrong, but that the theory is wrong or at least incomplete, and that the observations merely discovered that it was not self-consisrent.

Quantitative experiments on autothixotropy and its hysteresis

Two different, independent strategies were used for quantitative experimental research on the autothixotropy of the water:

1. The static method of torsion.

2. Two dynamic methods: the method of torsion oscillations and the method of small balls falling in water under condition of laminar flow.

The results have been published by Vybíral,^{[5] and [9]} and are summarised below. Static torsion method

Principle

A stainless steel plate is suspended on an elastic filament of torsional rigidity k_τ, and immersed in the studied water (Figure 1). The water is in a steady state and the ideal fluid model is assumed. Thus, if we twist the upper end of the filament by angle φ_u, we expect that the plate will follow the rotation, so that φ_d=φ_u, φ_d being angle of rotation of the plate. According to our experiments, this equality was not achieved. In the static experiment, a series of increasing values of angle φ_d is observed, following a very slow, ‘step by step’, change of angle φ_u. One can specify the moment of force M_w, arising when the plate influences the water: M_w=k_τ (φ_u–φ_d). If angle φ_u reaches a critical value (φ_u)_crit., the rotation of the plate (ie ) becomes quick.

Experimental device

The equipment that was used for the experiment is illustrated in Figure 1. The phosphor–bronze filament had a length L=465 mm and a cross-section of 0.20×0.025 mm². The torsional rigidity of the filament was determined experimentally from torsion oscillations of the plate hung in non-perturbed air:⁵ k_τ=(1.01±0.02)×10⁻⁷ Nm/rad. After reduction to the unit length (1 m), we get k_τ1=(4.69±0.07)×10⁻⁸ Nm²/rad. The results shown here are related to an experiment with a flat stainless steel plate of width b=38.5 mm, height h=60.5 mm, thickness 0.50 mm and mass 8.50 g. Angles φ_u and φ_d were read with an accuracy of 0.5°. Water used for the experiment was distilled and then boiled for 3 min before the experiment began. In the course of the experiment, the temperature of the water was kept between 24 and 25 °C. Water with volume of approx. 350 ml was in a glass vessel with an inner diameter of 80 mm and a height of 110 mm. The vessel was closed with a paper lid with a small opening for the filament. The lid was removed only briefly to read the scale.

Quantitative experimental results

Measurements of the critical angle (φ_u)_crit.

The critical angle is the angle φ_u at which, when reached by the hanger the plate began to rotate (relatively quickly, in a time scale of tens of seconds) in the same direction. Some prominent results of repeated measurements⁵ are:

1. The plate immersed with 65% of its surface in water, which had been standing for seven days: (φ_u)_crit.=(398±3)°.

2. With the water boiled for a short time, but otherwise the same configuration of system (immersion 65%). After cooling (24 °C): (φ_u)_crit. ≈ 30°, after two days: (φ_u)_crit.≈115°.

3. With the water boiled, the plate entirely immersed (the upper edge 10 mm below water level), the critical angle measured on the second and third day was (φ_u)_crit.=(356±3)°.

4. The plate immersed only 50%: (φ_u)_crit.=(343±8)°.

5. The influence of plate immersion on the critical angle (φ_u)_crit. is small: for plate immersion in the range 100–23%, the difference is Δ(φ_u)_crit.≈ 14%.

6. The period of a water-standing influences the magnitude of the critical angle. For example, with immersion of 85% of the surface of the plate and a long period of standing (17 days), we observed (φ_u)_crit.=1800°. As a consequence of the ‘rupture’ which followed, the plate rotated through the angular interval Δφ_d=1430°. With total immersion such a great critical angle was never reached.

7. After stabilization of the position of the plate (ie, Δφ_d=1430°), a slow change of angle φ_d (‘creep’) was observed: 4° in 5 min and, another 32°, in the subsequent 70 hours.

Reproducibility

The results for a given configuration of the measurement system have good reproducibility. For example, if the water was boiled and stood for 24 h, with the plate totally immersed in water for 14 days, six measurements of angle φ_d were performed. For the same set of angles φ_u : 60°, 120°, and 180°, the measured respective average angles φ_d were: (19.6±0.7)°, (34.4±0.6)°, (52.3±1.3)°. When (φ_u)_crit.=(239±2)° was reached, the plate quickly rotated (tens of seconds) and reached a new equilibrium position (φ_d)₀=(198±2)°.

Hysteresis

Hysteresis means that a system does not instantly follow forces applied to it, but reacts slowly or does not return completely to its original state: its state depends on its history. Measurements for a cyclical change of angle φ_u were carried out. The results of three measurements are shown in Figure 2 and Figure 3. Figure 2 shows the results for the plate entirely immersed in the water which was thoroughly stirred 17 h before. While changing angle φ_u from the starting equilibrium position φ_u=φ_d=0°, the change of angle φ_d did not follow an ideal straight line φ_u=φ_d, but the curve O–A. At point A the critical value (φ_u)_crit.1 was reached and then the plate rotated to a new equilibrium position—point B. With decreasing angle φ_u, angle φ_d changed according to curve B–C, until it reached the second critical value, denoted (φ_u)_crit.2, then the plate rotated to another equilibrium position—point D. When angle φ_u was decreased again, the position of the plate went through the origin O to the third critical position—point E, with the third critical value, denoted (φ_u)_crit.3. Another equilibrium position corresponded to point F and the fourth critical position corresponded to point G, where (φ_u)_crit.4(φ_u)_crit.2. As the plate rotated further, a fourth equilibrium position point H, approximately identical with point D, was reached. From there, with decreasing angle φ_u, the position of the plate followed the previous section H–O and for φ_u=0° it returned to the original equilibrium position φ_d0°.

Figure 3. Results of two experiments (loops of the changes of angle φ_d=f (φ_u)): with the completely immersed plate (loop a) and with half-immersed plate (loop b).

In Figure 3, the results of two other experiments with water standing for one week are presented: Loop a refers to experiment with the plate totally immersed, loop b to the experiment with the plate half-immersed; the effect is more pronounced for the half-immersed plate. The loops in Figure 3 are simpler than those in Figure 2 and the respective values (φ_u)_crit. are lower. This can be explained on the microscopic level: The plate probably deformed clusters of water molecules of various dimensions and rigidity.

These experiments suggest that the mechanical properties of clusters of water molecules display hysteresis. The hysteresis is however limited; in our experiment, for instance it does not appear in situations when the critical angle is not reached. For example, if a position of the plate corresponds to a point in the section O–A of the graph in Figure 2, before point A is reached, and if we begin to decrease angle φ_u, the character of the change of angle φ_d will follow the same curve O–A backwards. In these situations, the cluster seems to behave like an ideal elastic body. The dynamics of the phenomenon are similar to those of synovial fluid lubricating the joints of section, which is determined by the thixotropy of the hyaluronic acid present.

Additional measurements

During the experiment, some additional measurements were made to eliminate possible influences on the observed phenomena:

1. The pH of the sample of water was determined by potentiometric measurement. It did not change significantly over a long period; in the range of temperature from 24 to 25°C the pH moved in the range 7.1–6.9.

2. The electrical conductivity of entirely fresh water was 5.6 μS/cm, and after five weeks it increased to 30.5 μS/cm at 25 °C. A dependence of the observed water properties on this change was not noted.

3. Surface tension: Using a Du-Noüyho apparatus (with an accuracy of 1%), no measurable change of the surface tension was found.

Experiments with deionized water

In the second phase of these experiments, water, which was first distilled and then deionized, was used. These experiments showed that in deionized water the phenomenon of autothixotropy and its hysteresis was absent. The same equipment (Figure 1) was used for the experiment and the plate was immersed both to one half and entirely as well. The water stood for 10 days before the measurement. The rotation angle φ_d of the plate, which passed through the interval φ_d(0°, 360°, 0°), was equal to angle of torsion φ_u of the upper end of the filament, with accuracy of 1.5°, as evaluated from the repeated measurements. Neither the existence of critical angles (φ_u)_crit., nor the phenomenon of hysteresis, were found. From this experiment, we arrived at the important conclusion that the autothixotropy of water, characterized by a non-zero critical angle and hysteresis is caused by the presence of ions in the water.⁵

Method of torsion oscillation

Principle

A plate hangs on a filament (with torsional rigidity k_τ) with their axes of symmetry aligned. The moment of inertia of the plate, relative to its axis, is I. We immerse the plate in the water (Figure 1) and measured its torsion oscillations in two situations:⁵

• In ‘fresh’ water (ie with negligible autothixotropy), under assumption of a viscous damping of the water, the period of free damped oscillations is T₁.

• In ‘stood’ water (ie with autothixotropy and viscous damping of the water), we suppose that it is necessary to add, to the quantities related to the elasticity of the filament with torsional rigidity k_τ, the elasticity parameter of putative clusters of water molecules in the considered situation, represented by torsional rigidity k_w. Then period of free damped oscillations is T₂.

By measuring the periods of oscillation T₁ and T₂, we can determine the moment of inertia I (eg, from the plate dimensions and its mass), and calculate the equivalent torsional rigidity:

Quantitative experimental results

For the measurement, an aluminium plate with a thickness of 2.95 mm, width b=(47.59±0.03) mm, height h=(50.59±0.02) mm and mass 18.70 g, was used. Its moment of inertia was calculated from its dimensions and mass: I=(7.518±0.001)×10⁻⁶ kg m². The plate was hung along its longitudinal axis of symmetry on a phosphor–bronze filament of cross-section of 0.025×0.2 mm² and length of L=569 mm. The filament had a torsional rigidity k_τ=(8.25±0.12)×10⁻⁸ Nm/rad.⁵

The plate was immersed in distilled and boiled water so that the upper edge of the plate was 14 mm above the level of the water surface. The water with a volume of approximately 400 ml was in a glass vessel with an inner diameter 80 mm and height 110 mm; the experiment was carried out at a temperature of 23°C. The period of the damped torsion oscillations was measured three times.

First in fresh water. The period of oscillation was T₁=(101.7±1.2) s. Then the system was left at rest for seven days. Then plate was carefully rotated from this equilibrium position by 45°, and at that position it stayed. Then, the plate was given a torsional pulse, initiating damped torsion oscillations. The period of oscillation was measured ten times; resulting in T₂=(5.34±0.06) s. The torsional rigidity of this system with autothixotropy was determined to be k_w=(1.04±0.03)×10⁻⁵ Nm/rad. The degree of the level of autothixotropy of the system, is ascertainable by means of the measurement of critical angle (φ_u)_crit.. For our system this was ≈340°.

Conclusions

On this basis, it is possible to formulate some additional hypotheses about clusters of water molecules:

1. Clusters of water molecules may be of macroscopic dimensions, on scale of centimeters.

2. Clusters of water molecules may be destroyed by boiling or intense stirring or shaking.

3. Clusters of water molecules have certain mechanical properties analogous to the properties of solid substances, such as elasticity/rigidity and strength, but these properties are much smaller than for solid substances with a relative magnitude of 10⁻⁶ or less.

4. Mechanical properties of clusters of water molecules show a certain hysteresis.

5. Water slightly deviates from an ideal Newtonian viscous fluid, because autothixotropy also appears in the form of internal static friction, although very weak.

6. From comparison of experiments with natural distilled water and deionizated distilled water it is possible to deduce that the cause of macroscopic clusters of water molecules are the ions contained in water.
