I learned about your product from a neighbor, a 91 year old farmer who is still going strong. He had severe reactions to exposure to poison ivy and got a prescription for rhustox and had been getting it locally from a pharmacy about an hour away. I went on line and found your product and ordered for myself and him and his wife. It has been a great help to all of us. We live in a remote area of rural West Virginia and regularly come in contact with poison ivy and poison oak so finding your product has been a God send.
