A lot of those claims about water physics used to market homeopathy are based on real experimental observations- see the link in my other reply, water really does do some strange and complex stuff.
But the problem is that these observations do not actually support the claims of homeopathy at all- the attempt at connecting the two is entirely nonsense. I like to try to be open minded about fringe science and medical ideas... but homeopathy really takes the cake, and is the type of total nonsense that gives the rest of that type of stuff a bad name.
