ABSTRACT BACKGROUND Homeopathic potencies 12CH and above cross the Avogadro number, and as such do not contain any original drug molecules in their aquous ethanol medium. It is thought H-bonded water structures preserved by ethanol carry the information of initial drug molecules. Potentized drugs show some differences with respect to their infrared (IR) absorption spectra. In a water-ethanol solution, free water molecules vary according the concentration of ethanol. In the present study the concentration of ethanol has been kept constant at 0.03 molar fraction in 6 different homeopathic potencies. OBJECTIVE To see whether different homeopathic potencies having fixed ethanol content show variation in free water molecules. METHODS Two potencies like 8CH and 32CH of three homeopathic drugs Natrum mur, Cantharis and Nux vomica were used in the study, and their ethanol concentration was kept fixed at 0.03 molar fraction. The control was considered to be aquous ethanol at the same concentration. Spectrum of pure water was also taken. Fourier transform infrared (FTIR) absorption spectra were obtained in the wave number region of 4000 – 2800 cm-1. The half-width at half-maximum was measured for each spectrum. The intensity of each spectrum was normalized at 3410 cm-1 close to the peak. The difference spectrum (absorbance of drug solution – absorbance of pure water) for each drug and the control was obtained. RESULTS FTIR spectra showed variation in absorbance intensity on both the high and low frequency side of the O-H stretching band in different drugs as well as the control. The C-H stretching band of 2977 cm-1 also showed variation in intensity in different drugs. In the difference spectra the absorbance intensity at the dip at 3630 cm-1 varied in different drugs and the control. The decrease in intensity at 3630 cm-1 and subsequent rise in intensity at lower frequency region represent the level of free water molecules and strong alcoholic O-H band around 3250 cm-1, respectively. CONCLUSION The drug and the control solutions show distinct variation in their FTIR spectra. The drugs have different levels of bound and free water molecules although their ethanol concentration is same. KEY WORDS Homeopathic potencies, FTIR spectra, free water molecules, intensity and difference spectrum.

Background: In homeopathy some drugs are known to act as complementary, antidotal or inimical to a particular drug. Practitioners can follow this rule when they apply one drug following another. Potentized Nux vomica can reduce acute hypnotic effect of alcohol on toads. Sulphur and Sepia are reported to be complementary to Nux-vom, while Coffea cruda and Zincum met are antidotal and inimical to Nux, respectively .The four drugs have been tested on the toad model to find out their actual therapeutic relationship with Nux vom. Objective: To verify the complementary effect of Sulphur and Sepia, antidotal effect of Coffea and inimical effect of Zincum in relation to Nux vom in the toad model. Methods: Five batches of toads, each comprising 20 individuals, were treated by partial immersion in a drug diluted with distilled water 1:500 for 20 min. The control consisted of 90% ethanol diluted with distilled water 1:500. The drugs were Nux vom 200 CH, Sulphur 200 CH, Sepia 200 CH, Coffea 200 CH and Zincum 200 CH. Toads of each batch were separately exposed to 260mM ethanol solution and tested every 10 min to see if they had lost their righting reflex (RR). For this, each toad was laid on its dorsal surface. If it failed to turn on its ventrum in a cut-off time of 60 sec it was considered to have lost its RR. Four more batches of toads were pretreated with Nux vom 200 CH and subsequently treated separately by Sulphur 200 CH, Sepia 200 CH, Coffea 200 CH and Zincum 200 CH. All the toads were then exposed to 260 mM ethanol solution to record their tolerance to ethanol anesthesia in terms of time to lose RR. Results: Toads treated with the five drugs took significantly longer time (P

Background: A common practice is to give homeopathic medication to nursing mothers to treat their children, assuming that the drug will be conveyed by the milk. In the case of conventional treatment, the drug molecules are indeed passed on from the mother to her breastfed infant. However, high dilutions (HD) above 12 cH, i.e., over Avogadro’s number, are traditionally held to lack any molecule from the starting material. If that is the case, then, does medication taken by the mother actually reach the child? To answer to that question, we developed plant models and demonstrated the transfer of HD effects between 2 groups of plants. Aims: To demonstrate the transfer of HD effects in an animal model in a much shorter time. Methods: Two batches of toads were respectively placed in two beakers, one containing Nux vomica 200 cH diluted with water 1:500 (direct treatment), and the other the same amount of distilled water were connected by cotton thread soaked in water and encased in a polyethylene tube (connected group); a third batch of toads (control) were placed in a beaker with 90% ethanol diluted with distilled water 1:500; all the animals were left 30 minutes, and then transferred to 3 independent beakers containing 209 mM ethanol. Every 10 minutes, the motionless toads were removed from the beakers, and placed on supine position, failure to recover the upright position after 60 sec was considered as loss of the righting reflex (RR). The experiment was replicated using large adult toads. Results: The percentage of toads losing the RR increased with the time of exposure to 209 mM ethanol in the 3 groups of toads. Significant difference in the percentage distribution was found between the control and the direct treatment and connected groups on χ2 test (p < 0.001, p < 0.01, respectively), whereby the latter required much longer time to lose the RR, and did not differed between them. In the experiment with large adult toads, the control group lost RR in 78 min, whereas the 2 treated groups did not lose RR even after 240 min. Conclusion: Nux-v 200 cH countered the hypnotic effect of alcohol in young toads, and this effect was transferred through capillary water in the cotton thread, supporting the transfer of the effect of homeopathic medication from mother to child.
