I've encountered this plant many times while hiking in our forest. I don't know if I've ever touched one or not - probably, but not on purpose (passing by them on a trail, for instance). If I did come in contact with them, it didn't affect me. My friend calls those plants "stinky flower" cuz they have kind of an obnoxious odor, especially when there is a large group of them. They are pretty - I love that color of purple!
