"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, concluctometry, pHmetry and galvanic cell electrodes potential," researchers in Naples, Italy report.
"Unexpectedly the physicochemical parameters evolve in time. The water solvent exhibits large changes in measurable physicochernical 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 physicochernical parameters vs sample age, and their dependence on the volume in which the dilution is stored," wrote V. Elia and colleagues, University of Naples.
The researchers concluded: "These new experimental results strongly suggest the presence of an extended and 'ordered' dynamics involving liquid water molecules."
Elia and colleagues published their study in Homeopathy (The 'memory of water': an almost deciphered enigma. Dissipative structures in extremely dilute aqueous solutions. Homeopathy, 2007;96(3):163-169).”
