Last fall I found a great soap for getting Poison Ivy oils off your skin and drying up poison ivy, your local grocery store sells it, called Seventh Generation Natural Dish Liquid, they also make laundry soap. Last week I had the area a top of my foot turning red and getting itchy,I washed it with the soap and smeared some on the area after drying my foot, did this also the next day, on day three all was clear...last spring I cleared a couple acres on the edge of the swamp..lots of vines..I washed down in the shower with this soap after each day of cutting and stacking brush piles...never got any poison ivy...it is great stuff, usually I'm getting the shots several times a year to clear up a case of poison ivy...thought I would pass on the info...Roy
