I had always heard that it took some other external event such as
burning the plant or using a weed eater or lawn mower to get the oil airborne. I have never heard of just inhaling the oil which
resides inside the leaf or its branches. In my case, I am around these plants all the time. The poison ivy literature mentions that one could pick up a poison ivy leaf and not get any urushiol on you provided the leaf didn't have any holes in it. It went on to say that a leaf without even a pin size hole was very rare.
I don't have answers to your other questions. |
