If you touch it, you will feel fire & pain like lightning, I know as I raked the underside of my arm across one that was on the underside of a leaf. I got it from my armpit almost to my wrist. Use ammonia topically -- it destroys the protein in the poison. Take a Tylenol or Advil or whatever and a Benadryl or other antihistamine.
