If you look up (henbane,detura, mandrake, belladonna) ect. you'll find even a larger list of herbs,flowers ect. that they use to make salves and potions with which are poisonous and/or hallucinogenic drugs. So for instance if they put it on crystals,stones ect. and hand it to you, you will paint it all over yourself(absorbed into skin) without knowing you are. In the old days they put it on saddles or on cups before serving you or in food then after it began to work the magic,spells ect. began. Google the names(in combination with witchcraft) and you'll realize it's a far more serious threat than most average people think. Be very careful around people you think are involved with witchcraft,pagan,ect.
