I have used Ivy Dry on myself and my son. It did help stop the itching temporarily. However, after repeated use on one rash (mine on the shin and his on his forearm where the skin is closest to the bone) I noticed a problem. The poison ivy rash eventually went away, but another scab was always there that itched--even several months afterwards. In fact, for my son, he had itchy scabs in that area for over a year.
One of the active ingredients in Ivy Dry is benzyl alcohol, which is made from benzene. Benzene is known to cause cancer, including leukemia. The CDC says this (among other things) about benzene, "Direct exposure of the eyes, skin, or lungs to benzene can cause tissue injury and irritation."
So I refused to use the product and properly disposed of it. (I am a healthy, mid thirties, female.)
