Being highly allergic to poison ivy, I can say that it helps with the itching, as well as drying it up. I lather it up, pat the lather thickly on the PI patches and let it dry. We've also been told by several of our customers that it's excellent for itchy insect bites as well. Being here in La., home of the 'killer mosquitos', wasn't hard to test that one, and it does work.
