No, it would seem it would be contagious. But it's not. That swelling isn't really anything from the actual plant at all. I had poison ivy blisters real bad between my fingers...stiffened everything up real bad. So i went agaisnt what i heard and using a razor i slut off the blisters and washed it thorougly in hot water and used a lot of soap to prevent infection. The liquid didnt spread anywear. And it got rid of those blisters. |
