Ringworm of the groin, also called tinea cruris, is treated primarily with antifungal medications. You need to use the right medicines and follow the doctor’s instructions. Ringworm is caused by a fungal infection that is transmitted through skin-to-skin contact. Antifungal drugs mainly include oral itraconazole capsules or terbinafine tablets, etc., and also topical terbinafine hydrochloride cream and bifonazole spray, etc. Oral and topical antifungal medications can be used together to enhance efficacy. Some Chinese herbs, such as bitter ginseng, white moss skin, raw thymus and other decoctions have a very good fungicidal effect, and you can also use proprietary Chinese medicines, such as compound hibiscus bark tincture, skin hemorrhoidal ointment, and so on. If you have ringworm, it is recommended that you go to the hospital in time to receive standardized diagnosis and treatment, and the medication should be used according to the doctor’s instructions.
