I did look into principles of homeopathy, because I always double check all prescriptions to me and my family. I was shocked that there were no studies confirming their effect, that mood of pharmacist who makes homeopathic substance influences product quality, that homeopathic product follows principle of substance "memory", though simple tap water has "memory" of all possible substances in the world.

But I never dismiss power of human belief. So I allow homeopathics to be bought to family members who believe in them.
