If no one has not suggested it already, I would highly recommend Wild Oregano Oil. You can apply this topically. Be certain you get a source from the Mediterranean, such as the Wild Oregano Oil sold by North American Herb and Spice Company. The farm grown oil does not contain the Antibiotic chemical component P73, and thus would be useless. Only the Mediterranean grown Wild Oregano Oil has this vital p73 that does the magic.
