Hydrogen peroxide can assist in treating ringworm. Ringworm is a type of dermatophyte—a type of pathogenic fungus that grows on body surfaces—that hydrogen peroxide is classified as being effective against.
While it is recommended to get antibiotics from a certified doctor, hydrogen peroxide has been shown to assist in treating ringworm by applying it to areas of affected skin. Application involves spreading the hydrogen peroxide over the skin, making sure to cover the entirety of the affected areas. If this does not work, it is recommended that an individual acquires antibiotics from a doctor or antifungal cream from a local chemist.
