A couple of weeks ago, I was brush-hogging my pasture when the weeds wrapped around the drive shaft so bad that I had to stop and cut them off with a knife. When I cut them off, I didn't realize that I had taken out some poison ivy vines. By the time the driveshaft beat the snot out of the vines, and I cut them off, I was covered in the sap from the vine. I usually don't get it too bad, but this time I got nailed. I sought advice from a biology professor that I know, and he recommended a product called Tecnu Scrub. I had blisters between my fingers, on the palms of my left hand, on my arms, and on my face. After two days of using Tecnu Scrub, all signs of the rash was gone. Nothing else I did helped. Bleach, alcohol, calamine, and everything else I could think of didn't do it.
I now keep a tube in the truck, in the office, and at home.
