DMSO cures Poison Ivy and Oak. How I use: I open the blisters with a dull spoon or knife then I apply the DMSO directly to the entire area at full strength:99.9 % pure DMSO.The itching stops immediately and the rash completely dries up w/in 3 to 4 days. I have used in this manner over 100 times and it has never failed to cure and I have never had an adverse reaction.I do not go camping or hiking w/o a bottle in my pack.
