Ginny, My younger brother was the type to get poison of one type or another if the wind blew his way. One time he got into sumac and he was swollen from head to toe, even his eyes swelled shut. Worst case of poison that I have ever seen. I used to have to go out and pick a weed(?) that grew in the grass. We called it buckcorn or buckorn. Took vast amounts. If I had a nickel for everyone of those leaves I gathered I would be rich. My mother would squeeze or heat and get the juice out and apply to his poison. That was the only thing that helped him back then. Later he went and got shots when affected. Pat
