Yes I have used it for Poison Oak/Ivy and it is miraculous. All these know it alls that want to sound like they know what they are talking about, saying it won't work, do not know what they are talking about. I had it really bad and have had it every summer for years having to go to the hospital for steroids etc. I always put it off till I scratch so much I get it in my eyes. I battled it back for 2 weeks putting off going to the ER. I was about to give in bc it was getting worse, and had a scratchy throat and went to the kitchen and drank about a Tablespoon of CS for my throat and IMMEDIATELY the itching stopped. I took it internally, not spraying it topically. It was amazing! In minutes the itching stopped and the Poison Oak stopped spreading immediately. To all the nay sayers: a man with an experience is never at the mercy of a man with an argument. It works! Immediately!!!
