Does water have memory?
I don’t think so – but it’s amazing how many people do and of course this theory is at the heart of the alleged efficacy of homeopathic medicines. This page from Wikipedia explains:
“While some studies, including Benveniste’s, have reported such an effect, double-blind replications of the experiments involved have failed to reproduce the results, and the concept is not accepted by the scientific community. Liquid water does not maintain ordered networks of molecules longer than a small fraction of a nanosecond.”
