Well, poison ivy itself isn't poisonous - it's the urushiol oil is the problem. One nanogram (that is, one billionth of a gram) is enough to affect an individual. Only roughly 15% of the world's population is NOT allergic to urushiol oil. So, be careful! Don't touch poison ivy, for it is better to be safe than sorry.
