Definitely some wicked stuff. In my case, I've only encountered a red rash and the itch. Mostly, I recognize the plant and steer clear. On a side note, @papa-pepper and I used latex dipped gloves when clearing some of his ivy-bearing land in AR. I opened the bin containing my chainsaw and those gloves last week. The latex on the gloves looked like it was actually melting in places. Could that have been a reaction to urushiol? Btw, I threw them out.
