Well, just to confuse the issue even more ... I think sensitivity to poison ivy can come and go! Our 20 acres has a woods with lots of poison ivy, and we wanted to cut out a walking trail by the creek. For years I had never got a case of rash, like some said, practically rolling in the stuff. I could pull it out with bare hands, handle it for hours, no rash. Then a couple of years ago, I got a mild case of rash, and it lasted a week or so. Last year again, I handled it quite a bit, and no rash.
