The mememory of water 2

The ‘memory of water’ is a popular phrase that is mostly associated with homeopathy and Jacques Benveniste following his and others’ allergy research work . These research teams reported that solutes subjected to sequential physical processing and dilution show biological effects different from those apparent using just the water employed for the dilutions. The subject has drawn a lot of controversy with many scientists simply rejecting it outright without studying the evidence.
The subject area has recently been the subject of a number of papers in the journal Homeopathy (July, 2007)c and has been reviewed . Although there is much support for water showing properties that depend on its prior processing (that is, water having a memory effect), the experimental evidence indicates that such changes are due primarily to solute and surface changes occurring during this processing. Certainly, simply stirring a solution may have pronounced effects on the vessel's surface charge and chemistry which can last for several minutes after the stirring has ceased .
Another memory scenario concerns individual O:H–O hydrogen bond possessing memory of their physical temperature and pressure history that lasts over periods of minutes . This hypothesis, although well published in peer-reviewed journals, needs further substantiation. The experimentally corroborated memory phenomena cannot be taken as supporting the basic tenets of homeopathy although they can explain some effects .
