'Unconventional' experiments in biology and medicine with optimized design based on quantum-like correlations.

In previous articles, a description of 'unconventional' experiments (e.g. in vitro or clinical studies based on high dilutions, 'memory of water' or homeopathy) using quantum-like probability was proposed. Because the mathematical formulations of quantum logic are frequently an obstacle for physicians and biologists, a modified modeling that rests on classical probability is described in the present article. This modeling is inspired from a relational interpretation of quantum physics that applies not only to microscopic objects, but also to macroscopic structures, including experimental devices and observers. In this framework, any outcome of an experiment is not an absolute property of the observed system as usually considered but is expressed relatively to an observer. A team of interacting observers is thus described from an external view point based on two principles: the outcomes of experiments are expressed relatively to each observer and the observers agree on outcomes when they interact with each other. If probability fluctuations are also taken into account, correlations between 'expected' and observed outcomes emerge. Moreover, quantum-like correlations are predicted in experiments with local blind design but not with centralized blind design. No assumption on 'memory' or other physical modification of water is necessary in the present description although such hypotheses cannot be formally discarded. In conclusion, a simple modeling of 'unconventional' experiments based on classical probability is now available and its predictions can be tested. The underlying concepts are sufficiently intuitive to be spread into the homeopathy community and beyond. It is hoped that this modeling will encourage new studies with optimized designs for in vitro experiments and clinical trials.

Interaction of homeopathic potencies with the water soluble solvatochromic dye bis-dimethylaminofuchsone. Part 1: pH studies.

INTRODUCTION: Previous studies have demonstrated the potential of solvatochromic dyes for investigating the physical chemistry of homeopathic potencies. RESULTS: Following examination of this class of dyes in organic solvents, results obtained using the positively solvatochromic dye Bis-dimethylaminofuchsone (BDF) in aqueous solution are now reported. Spectral changes observed with this dye in the presence of potencies are both substantial and reproducible. Studies across a wide range of pH values reveal an unusual pH dependence for the dye's interaction with homeopathic potencies. Results indicate potency enhances dye protonation at pH values below c. 7.0, whilst protecting the dye from attack by hydroxyl ions above c. pH 7.5. CONCLUSION: A possible explanation for these observations is offered in terms of a potency - induced electron density shift in BDF. The interaction of homeopathic potencies with solvatochromic dyes, particularly BDF, points towards a possible physico-chemical model for the nature of potencies, how they may be interacting with this class of dyes, and moreover how their biological effects may be mediated.

Nuclear Magnetic Resonance characterization of traditional homeopathically manufactured copper (Cuprum metallicum) and plant (Gelsemium sempervirens) medicines and controls.

BACKGROUND: NMR proton relaxation is sensitive to the dynamics of the water molecule H2O, through the interaction of the spin of the proton (1H) with external magnetic and electromagnetic fields. METHODS: We measured dilution and potentization processes through measurements of 1H spin-lattice T1 and spin-spin T2 relaxation times. In order to interpret the recorded fluctuations in T1- or T2-values, experimental data were linearized by investigating how the area under a fluctuating time = f(dilution) curve (dilution integral or DI) changes with dilution. Two kinds of fitting procedures were considered: chi-square fitting with a goodness-of-fit probability, and least absolute deviations criterion with Pearson's linear correlation coefficient. RESULTS: We showed that fluctuations are not attributable to random noise and/or experimental errors, evidencing a memory effect quantifiable by the slope of the DI = f(dilution) straight line. For all experiments, correlation coefficients were found to lie above 0.9999, against 0.999 for random noise. The discrimination between experimental slopes and slopes associated with random noise data was very good at a five-sigma level of confidence (i.e. probability 3 × 10-7). Discrimination between experimental slopes at a five-sigma level was possible in most cases, with three exceptions: gelsemium aqua pura v gelsemium dilution (four-sigma); copper aqua pura v gelsemium aqua pura (four-sigma) and copper simple dilution v gelsemium simple dilution (three-sigma). All potentized samples show very good discrimination (at least nine-sigma level) against aqua pura, lactose or simple dilution. It was possible to transform the associated relaxation times into a molecular rotational correlation time τc and an average spin-spin distance d. Our experiments thus point to a considerable slowing down of molecular movements (τc > 1300 ps or T = 224-225 K) around water molecules up to a distance of 3.7 Å, values. It was also possible to rule out other possible mechanisms of relaxation (diffusive motion, 17O-1H relaxation or coupling with the electronic spin, S = 1, of dissolved dioxygen molecules). CONCLUSION: There is clear evidence that homeopathic solutions cannot be considered as pure water as commonly assumed. Instead, we have evidenced a clear memory effect upon dilution/potentization of a substance (water, lactose, copper, gelsemium) reflected by different rotational correlation times and average H⋯H distances. A possible explanation for such a memory effect may lie in the formation of mesoscopic water structures around nanoparticles and/or nanobubbles mediated by zero-point fluctuations of the vacuum electromagnetic field as suggested by quantum field theories. The existence of an Avogadro's 'wall' for homeopathically-prepared medicines is not supported by our data. Rather it appears that all dilutions have a specific material configuration determined by the potentized substance, also by the chemical nature of the containers, and dissolved gases and the electromagnetic environment. This sensitivity of homeopathically-prepared medicines to electromagnetic fields may be amplified by the highly non-linear processing routinely applied in the preparation of homeopathic medicines. Future work is needed in such directions. The time is now ripe for a demystification of the preparation of homeopathic remedies.

[Suitable investigation method of exploration and suggestions for investigating Chinese materia medica resources from wetland and artificial water of Hongze Lake region].

According to the technology requirements of the fourth national survey of Chinese Materia Medica resources (pilot), suitable investigation method of exploration and suggestions for investigating Chinese Materia Medica resources was proposed based on the type of wetland and artificial water of Hongze Lake region. Environment of Hongze Lake and overview of wetland, present situation of ecology and vegetation and vegetation distribution were analyzed. Establishment of survey plan, selection of sample area and sample square and confirmation of representative water area survey plan were all suggested. The present study provide references for improving Chinese materia medica resources survey around Hongze Lake, and improving the technical specifications. It also provide references for investigating Chinese Materia Medica resources survey on similar ecological environment under the condition of artificial intervention.

From high dilutions to digital biology: the physical nature of the biological signal.

The memory of water was a radical idea that arose in the laboratory of Jacques Benveniste in the late 1980s. Twenty-five years have passed and yet the often angry debate on its merits continues despite the increasing number of scientists who have reported confirmation of the basic results. 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. A parallel can be drawn between this debate on the memory of water, which presumes that the action of molecules is mediated by an electromagnetic phenomenon, and the often acrimonious debate on the transmission of nerve influxes via synaptic transfer of specific molecules, neurotransmitters. The latter debate began in 1921 with the first experiments by Loewi and was still active in 1949, 28 years later. A strong reluctance to accept research that questions basic aspects of long-accepted biochemical paradigms is to be expected. In this paper we will provide a brief summary of experiments relating to the memory of water: the earlier work on high dilutions (HD) and then the experiments, which followed and continue today, on digital biology.

Gas nanobubbles and aqueous nanostructures: the crucial role of dynamization.

Nanobubbles (NBs) have been a subject of intensive research over the past decade. Their peculiar characteristics, including extremely low buoyancy, longevity, enhanced solubility of oxygen in water, zeta potentials and burst during collapse, have led to many applications in the industrial, biological and medical fields. NBs may form spontaneously from dissolved gas but the process is greatly enhanced by gas supersaturation and mechanical actions such as dynamization. Therefore, the formation of NBs during the preparation of homeopathic dilutions under atmospheric pressure cannot be ignored. I suggested in 2009 the involvement of NBs in nanometric superstructures revealed in high dilutions using NMR relaxation. These superstructures seemed to increase in size with dilution, well into the ultramolecular range (>12c). I report here new experiments that confirm the involvement of NBs and prove the crucial role of dynamization to create superstructures specific to the solute. A second dynamization was shown to enhance or regenerate these superstructures. I postulate that superstructures result from a nucleation process of NBs around the solute, with shells of highly organized water (with ions and silicates if any) which protect the solute against out-diffusion and behave as nucleation centres for further dilution steps. The sampling tip may play an active role by catching the superstructures and thus carry the encaged solute across the dilution range, possibly up to the ultramolecular range. The superstructures were not observed at low dilution, probably because of a destructuring of the solvent by the solute and/or of an inadequate gas/solute ratio.

Survey of immuno-allergological ultra high dilution research.

BACKGROUND: Experiments about basic research in Immuno-allergology reported by M. Bastide and B. Poitevin in Ultra High Dilution (1994) have been appraised from a 20 year perspective. The numerous experiments published mainly focus on immunological regulation, inflammatory process and basophil activation. They are analyzed according to one essential criterion: repeatability. METHODS: The commentary reflects the research details made available in a recently published literature review, also published in French. RESULTS: The regulatory effect of high dilution of bursin on immune response has been observed in multiple experiments but not reproduced by independent teams. The immunomodulating effect of Thymulin has been confirmed in mice. Rhus toxicodendron has an anti-inflammatory activity on different models, from mother tincture (TM) to very high dilutions. The homeopathic complex Canova activates macrophages in vitro and in vivo, induces lymphocyte proliferation, and reduces the size of tumors and mortality of sarcoma-bearing mice. Some homeopathic medicines used in clinical inflammation modulate in vitro the neutrophil activation, with variability in the protocols used and in the medicines tested. In allergology, high dilution histamine has an inhibitory effect on basophil activation in multicenter trials and with independent teams, either with methods implying a change in basophil staining or with flow cytometry. However, high dilution histamine had no effect in some well-conducted experiments. The inhibitory effect of Apis mellifica has not been studied with the flow cytometry method, as well as the activation of basophil by anti-IgE high dilution, published in Nature. CONCLUSIONS: Despite considerable research activity in immuno-allergology and a great increase in the number of publications, there is still not in this domain a "gold standard" trial in basic research in homeopathy. The most studied system, the inhibitory effect of histamine high dilutions on basophil activation, requires clarifications of various factors, including individual sensitivity. For scientific and epistemological reasons, the same work should be carried out for independent reproduction of the experiments conducted with anti-IgE and Apis mel high dilution, in complement of the new axes of research in immunoallergology developed since 20 years.

Electromagnetic and magnetic vector potential bio-information and water.

This work developed over the past 40 years starting from dielectric measurements on enzymes and the subsequent finding that the measurements were affected by electric, magnetic, electromagnetic fields and quantum fields. A request for help in the diagnosis and therapy of chemically sensitive patients who had become sensitive to their electromagnetic environment came in 1982. The same symptoms could be provoked by a chemical or a frequency challenge and this led to an appreciation of the synergy between chemical and frequency environmental sensitivities. Experimental cooperation with theoretical physicist Herbert Fröhlich FRS and others led to an understanding of the physics of coherent water in living systems and a mechanism for the memory of water for coherent frequencies. In a coherent system there are interacting frequencies proportionate to any velocity the system will support, in particular the velocity of light and the velocity of coherence diffusion. Thus, there can be biological interaction between the optical, microwave and ELF spectral regions. Frequency modulation of light scattered by bio-fields and its retention in recorded images is discussed. A 'nil-potent' frequency can erase a frequency signature and thence affect a biological system. Homeopathy is interpreted through the biological effects of coherent frequencies derived from the frequency signature of the 'Mother Tincture' and developed through dilution and succussion. A homeopathic potency has a frequency signature therefore it must be able to have a biological effect.

High-dilution effects revisited. 1. Physicochemical aspects.

Several lines of evidence suggest that homeopathic high dilutions (HDs) can effectively have a pharmacological action, and so cannot be considered merely placebos. However, until now there has been no unified explanation for these observations within the dominant paradigm of the dose-response effect. Here the possible scenarios for the physicochemical nature of HDs are reviewed. A number of theoretical and experimental approaches, including quantum physics, conductometric and spectroscopic measurements, thermoluminescence, and model simulations investigated the peculiar features of diluted/succussed solutions. The heterogeneous composition of water could be affected by interactive phenomena such as coherence, epitaxy and formation of colloidal nanobubbles containing gaseous inclusions of oxygen, nitrogen, carbon dioxide, silica and, possibly, the original material of the remedy. It is likely that the molecules of active substance act as nucleation centres, amplifying the formation of supramolecular structures and imparting order to the solvent. Three major models for how this happens are currently being investigated: the water clusters or clathrates, the coherent domains postulated by quantum electrodynamics, and the formation of nanoparticles from the original solute plus solvent components. Other theoretical approaches based on quantum entanglement and on fractal-type self-organization of water clusters are more speculative and hypothetical. The problem of the physicochemical nature of HDs is still far from to be clarified but current evidence strongly supports the notion that the structuring of water and its solutes at the nanoscale can play a key role.

High-dilution effects revisited. 2. Pharmacodynamic mechanisms.

The pharmacodynamics aspects of homeopathic remedies are appraised by laboratory studies on the biological effects at various levels (cellular, molecular and systemic). The major question is how these medicines may work in the body. The possible answers concern the identification of biological targets, the means of drug-receptor interactions, the mechanisms of signal transmission and amplification, and the models of inversion of effects according to the traditional 'simile' rule. These problems are handled by two experimental and theoretical lines, according to the doses or dilutions considered (low-medium versus high dilutions). Homeopathic formulations in low-medium dilutions, containing molecules in the range of ultra-low doses, exploit the extreme sensitivity of biological systems to exogenous and endogenous signals. Their effects are interpreted in the framework of hormesis theories and paradoxical pharmacology. The hypotheses regarding the action mechanisms of highly diluted/dynamized solutions (beyond Avogadro-Loschmidt limit) variously invoke sensitivity to bioelectromagnetic information, participation of water chains in signalling, and regulation of bifurcation points of systemic networks. High-dilution pharmacology is emerging as a pioneering subject in the domain of nanomedicine and is providing greater plausibility to the puzzling claims of homeopathy.

Diverse biological effects of electromagnetic-treated water.

The effects of water treated with an electromagnetic field (EMF) were investigated on two biological systems, humans and plants. Purified de-ionised water was treated by (1) boiling, (2) exposure to microwave radiation, and (3) low frequency electromagnetic oscillation molecular resonance effect technology (MRET), before being used to prepare media for culturing human peripheral blood mononuclear cells (PBMC) from three healthy females. Our results indicated that PBMC culture in MRET-activated medium showed significantly less oxidative metabolism when compared to media prepared from other types of water. As for the effects on soybean, our results indicated that both MRET- and microwave-treated water greatly enhanced the length of the root. These results suggested that electromagnetic-treated water can have diverse biological effects on both animal and plant cells. Since these effects are related to the 'Memory of Water', hypothesis which has been suggested as an explanation of the action of high homeopathic dilutions, our finding warrant a further investigation on the mechanisms of various types of physically conditioned water on specific cellular activities.

Beware of Neurotoxins in Common Plants: Water Hemlock Poisoning Presenting as Convulsive Status Epilepticus.

BACKGROUND: Pediatric status epilepticus occurs in about 44/100.000 children per year with an unknown cause in about a third of patients. One cause can be the ingestion of plants containing toxins that target the central nervous system. Here we describe an ingestion of water hemlock resulting in a status epilepticus. METHODS: We studied in detail the clinical, laboratory, electrophysiological, and radiological features of a patient with status epilepticus. RESULTS: A 9-year-old boy presented to the pediatric emergency department for sudden onset of nausea, vomiting, and status epilepticus approximately one hour after the patient had bitten into the root of a water plant in an inner-city park. Bilateral tonic-clonic seizures could only be terminated after administration of midazolam, lorazepam, and finally propofol. Cranial MRI, cerebrospinal fluid, and EEG findings were largely unremarkable. The ingested plant was identified as water hemlock through a detailed search with the help of a drawing issued by the patient with the help of the medical team. The specific toxicological analysis for water hemlock verified the presence of cicutoxin and cicudiol in the blood sample. The patient was discharged, levetiracetam was weaned off four weeks later, and he has remained seizure free since. CONCLUSIONS: Given the considerable percentage of cases of unknown etiology in new-onset pediatric status epilepticus, it is important to consider plant intoxication as a possible cause.

Evaluation of diazepam as a drug treatment for water hemlock (Cicuta species) poisoning in Spanish goats.

Water hemlocks (Cicuta spp.) are toxic members of the Apiaceae plant family. The best drug treatment for the convulsions associated with acute water hemlock poisoning in livestock and humans has not been determined experimentally. This work compared the therapeutic actions of benzodiazepines (diazepam) and barbiturates (phenobarbital) on water hemlock poisoning in a goat model. C. maculata tubers were orally dosed to goats. Experimental groups consisted of; control saline; 20 mg/kg phenobarbital; 1.0 mg/kg diazepam; 10 mg/kg diazepam; and 1.0 mg/kg diazepam administered as needed to moderate convulsions by intravenous (i.v.) infusion. Diazepam provided nearly instant control of convulsions. Clinical signs of poisoning were completely controlled for the duration of the experiment in the goats that received the 10 mg/kg diazepam dose. These results suggest that diazepam is effective at managing the clinical signs of water hemlock poisoning in goats. We speculate that diazepam can be used as a potential treatment for water hemlock poisoning in other livestock species and humans.

[Tonic water and quinine-a bicentennial booming cocktail]. / Eau tonique et quinine ­ un cocktail de bicentenaire servi en pleine effervescence.

OBJECTIVES OF THE STUDY: During the SARS-CoV-2 pandemic, the media has often mentioned the presence of quinine in tonic water. Media accounts of quinine's antiviral effect in vitro, as well as press reports about quinine-based compounds, such as hydroxychloroquine, have sparked renewed public interest in drinking tonic water, which could perhaps result in an increase in allergic phenomena. On the 200th anniversary of the discovery of quinine, our main objective was to analyze hypersensitivity reactions, related to the consumption of beverages containing quinine, described in the literature. PATIENTS AND METHODS: We analyzed case reports indexed on Pubmed, Scopus, and Google Scholar. A quinine causality score was calculated for each of the observations. A quinine assay was performed on several beverages for which the quinine content had not been published. RESULTS: In parallel with related pharmacokinetic studies, these case reports consist of 26 observations. The case reports mainly related to young men, with symptoms of varying severity, mainly dermatological, with fixed drug eruption, generalized rashes, hives; hematological, with thrombocytopenia, hemorrhagic syndrome, thrombotic microangiopathy; more rarely ocular, cardiac or auditory. The level of causality of quinine is certain for three cases, probable for twenty-two, possible for two. The levels of quinine, all conforming to the standards, were lower in the spirits and the cooked wine than those of tonic water. DISCUSSION: Possibly under-diagnosed, the main mechanism of these reactions is immuno-allergic, without any cross-reaction with other quinolines having been shown. In these patients and breastfeeding women of G6PD deficient newborns, any medicines, phytotherapy, homeopathy, or even cosmetics containing quinine, on the basis of a proposed list, should be avoided.

The curious case of charles darwin and homeopathy.

In 1849, Charles Darwin was so ill that he was unable to work one out of every 3 days, and after having various troubling symptoms for 2-12 years, he wrote to a friend that he was 'going the way of all flesh'. He sought treatment from Dr James Manby Gully, a medical doctor who used water cure and homeopathic medicines. Despite being highly skeptical of these treatments, he experienced a dramatic improvement in his health, though some of his digestive and skin symptoms returned various times in his life. He grew to appreciate water cure, but remained skeptical of homeopathy, even though his own experiments on insectivore plants using what can be described as homeopathic doses of ammonia salts surprised and shocked him with their significant biological effect. Darwin even expressed concern that he should publish these results. Two of Darwin's sons were as incredulous as he was, but their observations confirmed the results of his experiments. Darwin was also known to have read a book on evolution written by a homeopathic physician that Darwin described as similar to his own but 'goes much deeper.'

The acute toxicity of water hemlock (Cicuta douglasii) in a goat model.

Water hemlock (Cicuta douglasii) is one of the most toxic plants to livestock and humans. Little is known regarding the amount of plant required to cause death. The objective of this study was to determine a lethal dose of water hemlock in a goat model. Plants were dosed to goats via oral gavage of freeze-dried ground plant material. The results from this study suggest that 1-2 fresh tubers would be lethal to goats.

Environmental parameters modulate lead chloride toxicity on Artemia salina

Different environmental conditions can influence the effects of toxic agents on living beings. Recently, a series of experiments performed in Artemia salina submitted to different kinds of intoxication have shown that both, isotherapic and succussed watercan change Artemia salina ́s bio resilience at different levels. Moreover, it seems to vary according to the circalunar cycle. Objective:To verify if circalunar phases and water agitation can modify the toxicity of lead chloride on Artemia salina in vitro. Methodology:Artemia salina cysts were exposed to seawater containing 0.04% of lead chloride (equal to EC10 or 10% effective concentration, previously determined in a pilot study) in 96-well culture plates. Thirty-six experimental repetitions were performed in four series to observe the possible effects of adding stirred water, the so-called succussed water, and the moon phases. The hatched cysts were recorded after 48 hours using a digital microscope (1000x magnification) to identify the hatching percentage and the viability and mobility of the born nauplii. Results:The exposition of cysts to PbCl2 led to an increase in the hatching rate, and it was more evident during the full moon (p = 0.00014) The addition of succussed water into the seawater medium reduced this effect to the baseline levels. An increase in mobility was seen in nauplii born from exposed cysts during the full moon (p = 0.00077), but this effect was not affected by the treatment with succussed water. Discussion:Although the effects of lead chloride EC10 on the increase of nauplii hatching were expected, two environmental variables changed the sensitivity of cysts to this harmful stimulus. The circalunar cycle varied the hatching rate according to the moon phase, even in laboratory conditions, and the addition of succussed water into the medium reduced the hatching rate, even with different intensities according to the moon phase. The organization of nano and microbubbles generated after the succussion of water could be related to this protective effect and can explain, at least partially the effects of high diluted preparations on this biological context. Conclusion:Environmental factors, such as the circalunar cycle and products of water agitation, can modulate the adaptative control of hatching in Artemia salina exposed to lead chloride at EC10.

Homeopathy and high dilutions in the context of water structure research: the experience in the 9thWorld Water Forum ­2022

Water plays a vital role in adapting natural and human systems in a climate change scenario. Understandinghow this fundamental element of life is organized and functioning is essentialtogather, disseminate, and advanceknowledge about water at the micro and nanostructure level. With developments in the different research areas, the International Panel on Water Structure­IPWS was created during the 8thWorld Water Forum(WWF)inBrasília,2018,to connect researchersspecialized inwater structure under aninterdisciplinary perspective.In 2020 a partnership between CIRAT ­International Center on Water and Transdisciplinarityand WATER­a Multidisciplinary Research Journalhasbegun, intendedto organize a special edition on Water and Transdisciplinarityto be launched during the 9thWWF, in Dakar, on March 24th, 2022, in response to the challenges of our century, with the aim to disclose advanced knowledge about water at different structural levels, leading to a new understanding of it.The whole project was organized by Prof. Leoni Bonamin, from UniversityPaulista, with the support of the Editor-in-Chief Prof. Gerald Pollack, from Washington University at Seattle. The focus was on the cross-over of information with technical quality and bold thinking, as shown in Figure 1 below.Homeopathy wasincludedamong the themes.Aftera multi-step process, in which manuscripts were received (after personal invitationssent to more than 200 researchers in the field)andevaluated in a two-step peer review processto ensure maximum scientific understanding, the result showed a set of innovative contributions in which authors were allowed to be bold in their projects while careful with the methodology. Theentire process was carried out voluntarily by all the actors involved.Thus, the whole editorial process was philanthropic, there were no costs for the authors, and all articles were published as open access. Authors from five countries participated in this project: Brazil, India, Italy, Russia, and the United States. Different sessions were organized according to the topics: "Opinion Article," "Hypotheses," "Water Structure," "High Dilutions," "Water and Environment," and "New Devices."Fiveof twelve articles reported results on high dilutions, including its physicochemical propertiesandthe implications on biological systems, such as plants and aquatic animals [1-4]. This initiative inspired all to envision the possibility of offering practical solutions to old problems involving different ways of water management, which couldreduce social gaps and improve the quality of life fairly and universally.

High Dilutions of Drugs show Distinct Variation from each other in their Electronic Spectra

Drugs at high dilution (HD) produce therapeutic effect on man, animals and plants. Experimental evidence shows that free water molecules and hydrogen bond strength of OH groups constitute the physical basis of HDs which are otherwise devoid of original drug molecules. HDs are produced in aqueous EtOH by serial dilution of a substance with mechanical agitation or succussion in each step, and are called potencies. Three potencies 6 cH, 12 cH and 30 cH of two drugs Anacardium orientale and Natrum muriaticum(NaCl) and their mother tincture (MT) are used in this study. Electronic spectra of these MTs and potencies, all in 90% EtOH, were taken in the wavelength region of 190 nm ­350 nm. The objective is to find out any additional physical-chemical entities in potencies besides the aforesaid two factors. It was reported earlier that charge transfer (CT) interaction accompanies potentization of drugs. This study focused on the CT interaction. The results indicate that spectral pattern and absorbance intensities of the test samples vary from each other. Natm 6cH (absorbance 0.30 at 196.53nm), 12cH (abs. 0.06 at 196.53nm) and 30cH (abs. 1.32 at 196.5nm). Anac 6cH (abs. 0.33 at 203nm), 12cH (abs. 0.61 at 208nm) and 30cH (abs. 0.09 at 200.67nm). The spectrum of each potency shows two peaks. The 2nd peak at higher wave length belongs to CT interaction. Anac 6cH suc, 7cH unsuc. Insersections at 197.14nm with abs. 0.05, and 290nm with abs. 0.01. Anac 12cH suc, 13cH unsuc. Intersections at 196.93nm with abs. 0.06, and 273nm with abs. 0.00. Anac 30cH suc, 31cH unsuc. Intersections at 194.42nm with abs. -0.05, 238.03nm with abs. -0.01, 252.15nm with abs. -0.002, and 261nm with abs. 0.004. Natm 6cH suc, 7cH unsuc. Intersection at 199.44nm with Abs -0.11. Natm 12cH suc, 13cH unsuc. Instersection at 200.48nm with abs. -0.11. Natm 30cH suc, 31cH unsuc. Intersection at 204.24nm with abs. -0.08. Potentization involves CT interaction in consecutive potencies. Water and EtOH do not form a homogeneous mixture and have aggregates of EtOHand water molecules. CT interactions occur in these individual aggregates and are mostly inter molecular within EtOH or water. These aggregates vary from each other in the test samples. The spectra of test samples were analysed for margin of error (MOE). The MOE is very small (0.001-0.002%), and for this reason the difference between the spectra is significant. Besides that the intersection between consecutive spectra vary in number and position. It is concluded that water and EtOH aggregates and their relative distribution constitute additional physical-chemical basis of potencies.

Investigation of the influence of clathrate hydrate crystals on the structuring of homeopathic high dilutions

High dilutions (HD) of drugs used in homeopathy are mostly too dilute to contain original drug molecules. But evidences support their specific biological and therapeutic effects. The reason behind this is thought to be water structure characteristic of the original drug. Spectroscopic studies indicate that the specific water structure in HDs can be resolved into free water molecules, hydrogen bonding strength of water hydroxyl, number of hydrogen bonds and clathrate hydrate crystals (CHC). HDs are prepared in EtOH water solution by serial dilution and mechanical agitation, and are called potencies. The objective of the present study is to further confirm the presence of CHCs in the two potencies of three drugs. Electronic spectra of the HDs of the potencies indicate two broad peaks and marked difference in intensities of absorption. Furior Transform Infrared (FT-IR) spectra of the test potencies and their control show difference in intensity shift and contour shape of OH stretching and bending bands. All the experimental data indicate the presence of CHCs in varying amounts in the test potencies.
