Q. I was in Marine Corps boot camp early in 1970 and developed a bad case of jock itch. My drill instructor, although an extremely harsh and seemingly uncaring guy, had warned us all of this possibility and suggested using Listerine.
It worked beautifully, and the rash cleared up in just two days. Old-fashioned amber Listerine does burn a bit going on, but it works well. It is also good for athlete’s foot.
A. Thanks for reminding us that the herbal extracts and alcohol in original formula Listerine have antifungal activity. That may explain why readers of this column report that it helps fight dandruff, nail fungus, athlete’s foot and seborrheic dermatitis. Other remedies that have won readers’ praise for treating jock itch include vinegar, dandruff shampoo (selenium sulfide) and the cleanser Cetaphil.
