Wow, can't imagine sitting in a patch of poison ivy! My family is highly allergic to it so we won't be eating it, but that is an interesting concept.
My son-in-law is a sheriff's deputy and he had to respond to a brushfire a couple of weeks ago. He did not know that the plant he was standing next to was sumac and he got it in his eyes and some other places. He was miserable for two weeks and just looking at his eyes made my eyes tear up.
