Homeopathy is bunk. Most people I encounter who disagree with this statement do not actually know what homeopathy is. They think it is some kind of herbalism or natural medicine. No – it is a prescientific superstition-based system of magic potions.
The basic idea is that you start with a fanciful treatment based on notions like sympathetic magic and incidental characteristics (like hair color). Then you dilute that fanciful treatment out of existence – so it doesn’t really matter anyway. Homeopathy is literally nothing, but homeopaths believe that the magical “essence” of the substance remains.
Unsurprisingly, clinical trials of homeopathic potions have convincingly shown that homeopathy works for nothing. So it can’t work, and in fact it doesn’t work.
So why is homeopathy still a thing? That is a fascinating question dealing with culture, human psychology, and political failure
