Q. I have been plagued with jock itch for weeks and had tried a couple of OTC creams with little success. I was getting ready to see my dermatologist when I read about using Listerine for jock itch, athlete’s foot, and other fungal infections.
Listerine has now cleared the problem up in a couple of days. It stings for a minute or two when first applied, but it isn’t that bad and it really worked.
A. The herbal oils in the original formula Listerine include eucalyptol, menthol and thymol. There is some evidence that these herbal extracts in combination may have anti-fungal activity. That may be why readers have reported that rinsing the scalp with Listerine can knock out resistant dandruff, which is also fungal in origin.
