I first heard about this solution a few years ago from a tree service owner who said he was allergic but cured his allergy by eating young leaves. (One of his new workers had just gotten exposed for the first time and his reaction was so bad he had to be taken the the ER.) Living on the California central coast, poison oak shows up on my property every year. Two or three times in the last couple of decades I've managed to make contact and get a rash, but it seemed to be less severe with each exposure. (I do remember my mother saying my sister would have a much worse reaction then me when playing outdoors as kids.) As an adult, I'm not sure if I'm building up immunity, or just getting better at avoiding prolonged contact.
