Forgot about the alcohol. Yeah, I know what you mean. I swear I can just look at it and I break out. Sucks too because I am the outdoors type and I always have to be on the lookout.I tried a bunch of remedies. I would run hot water over it and or a hot compress. then I would let it dry and put calamine lotion on it. I also used rubbing alcohol on it sometimes and it seemed to quell the itching also. Oh, and I took benedryl throughout the time I had it. This is what worked for me. The best defense is offense. If I know I have been in contact with it I wash it off wth soap and water immediately. I never want to get it again. It was miserable.
When I used to clear trails for Camp Jeep I used to carry a small travel size of Dawn with me and go wash up in a creek. Horrible little plant...
