THIS IS NOT MEDICAL ADVICE---
I made myself immune to poison ivy! for a week, I got, every day, a tiny new leaf, when they're starting to grow and the leaves are bright red, smaller than an inch. I used (ugh) Wonder bread to make a pill, the leaf inside. One a day for a week. No ill effects, and I've never gotten a rash since. This was in a Euell Gibbons book.
Oh, I did wash my hands after handling the leaves with lots of soap and near-hot water to wash off the oils that cause the rash.
THIS IS NOT MEDICAL ADVICE!! ( I've been flamed for telling people this tip.)
