It's curious how positive results only come from associates in an industry profiting from trying to convince you that their water, chemically indistinguishable from regular water, has magical healing properties through its memory of past events.
In case you are curious, here is a rigorous research paper on the topic. It is extremely hard to evaluate. Any researcher who would try to do this sort of research is immediately suspect, so it takes a certain type. But I see no reason to dismiss a priori.
See what you think (over 250 cites): Roy, R., Tiller, W. A., Bell, I., & Hoover, M. R. (2005). The structure of liquid water; novel insights from materials research; potential relevance to homeopathy. Materials Research Innovations, 9(4), 98-103.
They dismiss this criticism as undiscovered science, in much the same way fairies and leprechauns are undiscovered animals. They'll often cite quantum mechanics and even cosmology, the more esoteric the better, to try to shoehorn science into their beliefs.
I disagree with the results of the risk of bias assessments of the studies involved in that meta-analysis: https://www.nature.com/articles/s41390-022-02127-3/tables/1
Out of the 6 studies used, only 2 are from general research institutions. The other 4 are all specialists in homeopathy or private practices using homeopathy. Seems like the risk of bias there would be extremely high.
