Hey everyone!
So I discovered some mugwort near my house and did some research, and it seems like the two major uses it had was for female reproductive things (easing period cramps, inducing a period if late, expelling dead miscarriage tissue, inducing abortions, etc), and for magickal hallucinatory derivatives (divination, trance states, inducing prophetic dreams). From what I read, the two uses seem to be separable by how much you use, but I couldn't find anything describing what point that was. I'd like to know if there's a sort of measure (even if it's in cups of tea type measurements) that is a good rule of thumb as to where the hallucinogenic properties take noticeable effect, as I would like to avoid them if trying to treat menstrual issues on their own.
Thanks!
