Another one of the random queries used to get to this site:
horny goat weed
When I first saw this, I wondered what on earth it could be - a weed that makes goats horny?
Well, actually, it's not that far off - it's used in Chinese medecine as an aphrodisiac for both men and women, and as a herbal treatment for erectile disfunction in men, according to this Discovery health article. I'm not sure quite how goats fit into the equation though, and to be honest, I don't think I really want to.
It gets its name from when a chinese man noticed his goats were getting a bit..frisky and so he recorded what they were eating and noticed it was when eating a certain type of weed
