Investigation of the Physicochemical Behaviour of Homoeopathic Dilutions of Glycerol (Glycerinum) at the Temperatures (293.15 - 318.15) K: Volumetric, Acoustic and ViscometricStudy

The physicochemical studies of homoeopathic medicines provide better understanding regarding the presence and mechanism of their action in ultra-dilutions. The physicochemical behaviour of glycerol dilutions homoeopathic dilutions has been investigated from the measurements of densities, , ultrasonic speeds, u and viscosities,  of pure ethanol control (91% ethanol in water) and 33 dilutions of glycerol dilutions of potencies ranging from 1C to 200C at ambient temperatures and atmospheric pressure. From the experimental data, a number of physicochemical parameters, viz., the isentropic compressibilities, s , intermolecular free length, Lf , acoustic impedance, Z, relative association, RA, relaxation time, , ultrasonic absorption, /f 2 , pseudoGrüneisen parameter, , deviations in isentropic compressibility, s , deviations in intermolecular free length, Lf , deviations in acoustic impedance, Z, deviations in viscosity,  and deviations in pseudo-Grüneisen parameter, have been evaluated. These parameters showed diverse behaviour at certain potencies of these homoeopathic dilutions. The results have been qualitatively discussed in terms of prevailing interactions of these glycerol dilutions dilutions. The results indicated that that even in extreme dilutions (50C, 110C, 150C and 160C) the molecules of glycerol dilutions may be present in these homoeopathic formulations
