Water has a Memory?

By Michael Edmonds 07/11/2010 4


One of the claims that in the past has been used by homeopaths to explain how their remedies “work”, is that water has a memory, and that the succussing (shaking) of the solutions allows the water molecules in the solution to “remember” the active ingredient (e.g. arsenic oxide, anthrax, snake venom etc) even after it has been diluted out of the solution. This has always struck me as rather odd given the relative size of the molecules. For example in the diagram below represented in blue and green is a single molecule of anthrax toxin*, while in the white box to the lower right of the diagram is water). How could a small molecule like water remember something as enormous as the anthrax toxin?

It must be magic!

* Note – Anthrax poison extracted from diseased sheep spleen has been used to prepare homeopathic “treatments” for acne, gangrenous degenerations and apparently anthrax itself

  • It is a funny science blog indeed that poses a question and quickly concludes the answer is “it must be magic.” As I am not a scientist I suppose it must.

    • The question was rhetorical, given the absurdity of the idea that water could have a memory, as implied by homeopaths.

  • pretty colors but the anti’s will tell you water remembers because it’s really smart being the universal solvent-building block of life-found thru out the universe-so on sort of stuff.you need to show it;s not “smart’ by experiment.

    • Actually the onus should be on those who claim that water has a memory or is “smart” to prove their case. Many millions of experiments and applications use water and have never demonstrated that this simple molecule made up of one oxygen atom and two hydrogen atoms has memory or is “smart” .
