Could you tell me what's the best way to get rid of ringworm without going out and buying medications?

Don't know: Here are some inexpensive meds. I don't know a non-med route.Otc meds include: lotrimin, micatin, micaderm, Lamisil at and tinactin (tolnaftate)..

Topical antifungals: You have to go out and buy something. It won't go away on its own. Apply a topical antifungal treatment that you can buy over the counter to the involved skin several times a day until 1 week after the rash has resolved. You can use the same treatments that are used for athlete's foot.
