Quick relief. Quickly washes away the itch from poison-ivy, oak and sumac. If you get Poison Ivy, you know you'll want to use a product with proven effectiveness that you can trust. Look no further than Ivy-Dry, known and trusted for over fifty-years. The rash and blisters associated with poison ivy, poison oak and poison sumac, are all caused by Urushiol. Urushiol binds with the skin, and causes the itch and irritation associated with these irritants. The symptoms will persist until the Urushiol is completely removed from the skin. Ivy-Dry Scrub is a special blend of surfactants and detergents that bind with and quickly release the Urushiol from the skin. It can then be rinsed away and the irritation will subside. Ivy-Dry Scrub also contains soothing Aloe Vera & Vitamin E to help speed healing. Made in the USA.
