I had chronic itching (diagnosed as idiopathic urticaria). Besides prescription antihistamine and additional Benadryl for breakthrough itching, I had to use hydrocortisone cream for more localized itching. A friend gave me a soap rock. In a few weeks, I noticed that my skin was not as itchy. I credit the soap. I am decreasing the prescription antihistamine to every other day. So far, so good. I believe that I will be able to stop taking the med in the near future. Also, I love the different colors- so pretty.
