My anthro classes argued heavily in the direction you guys are leaning (if people have been doing it for this long it's probably not a horrible idea, people are good at noticing correlations) but another part of me is like, you know, there is a reason it's "traditional medicine" and not "what everyone in the world does." Like, if eating some herbs cured arthritis pain, wouldn't some company have started extracting whatever is in those herbs and selling it? I was actually supposed to read
a book about this.I guess my sense of traditional medicines is colored by reading a lot about it in the context of "Chinese people kill this nearly-extinct animal for its horn, to make aphrodisiacs (which don't work)." Sometimes people do things for many generations that are actually bad for them, or do nothing.
