Poison ivy, oak and sumac rashes are all caused by the same resinous oil. This oil produced by the plants is called urushiol (pronounced oo-roo-she-all). The rash is your body's allergic reaction to the oil. This results in an itchy, bumpy rash that can produce blisters filled with fluid. A common misconception is that breaking the blisters will cause the fluid to spread the rash. If your poison ivy, oak or sumac rash is spreading, it is because the rash-causing oil is spreading. Tecnu is the original poison ivy treatment, which can remove urushiol from nearly anything. Tecnu Extreme Poison Ivy Scrub is an all-body protective solution that handles all the tougher jobs.
