Instrumental measurements of different homeopathic dilutions of potassium iodide in water

Although more than 200 years have elapsed since the beginning of homeopathy and in spite of numerous confirmatory scientific experiments, the so-called memory of water is still a highly disputable and controversial theme in scientific circles. To make a contribution to solving this riddle, our research group tried to examine memory properties of water by the method of differential corona Kirlian electrophotography of water-drop pairs. The method is based on a modified form of Kirlian photography with a subsequent thorough computer picture analysis. The potassium iodide (KI) mother solution (0.1M) was diluted in the standard way (without potentisation) or with potentisation (succussion by hand - by striking the vial 60 times against a large book as used traditionally) to 10-3M, 10-6M, 10-10M, 10-16M, 10-17M, and 10-24M KI Solutions. In electrophotography method a drop of KI solution was compared with a drop of control water. To get a dependable system of results we compared homeopathic dilutions with ordinary distilled water, sham-potentised distilled water and non-potentised (standard) solutions. The results were analyzed by the Chi-square Goodness-of-fit test and the Sign test. They showed repeatable and statistically significant effects of concentration of KI dilutions as well as potentisation on the corona discharge process (from p < 0.05 to p < 0.001). This indicates that there is some physical basis of molecular (ionic) information imprinted into water.
