“According to a study from London, the United Kingdom, "The 'memory of water' is a concept by which the properties of an aqueous preparation are held to depend on the previous history of the sample. Although associated with the mechanism of homeopathy, this association may mislead."
"There is strong evidence concerning many ways in which the mechanism of this 'memory' may come about. There are also mechanisms by which such solutions may possess effects on biological systems which substantially differ from plain water," wrote M.F. Chaplin and colleagues.
The researchers concluded: "This paper examines the evidence."
Chaplin and colleagues published the results of their research in Homeopathy (The memory of water: an overview. Homeopathy, 2007;96(3):143-150).”
