Don't let poison ivy & oak interrupt your outdoor plans. With Tecnu Extreme Poison Ivy Scrub you can cleanse away the rash-causing urushiol oil from poison ivy, oak and sumac plants and get back to enjoying the outdoors. If you suspect, or know you have been, in contact with poison ivy plants, use Tecnu Extreme as an all over body wash. Mix the product with a small amount of water and gently scrub affected areas. Tecnu Extreme will gently exfoliate the skin and effectively remove the plant oils.
