Soaking feet in mugwort leaves has an inhibitory effect on various pathogenic skin fungi and can promote blood circulation through heat conduction. Athlete's foot is a type of fungal infection, especially common in the summer when people often wear sneakers or leather shoes. Feet soaked in sweat for prolonged periods and in non-breathable conditions are prone to developing athlete's foot. In Western medicine, athlete's foot is considered a fungal infection. Soaking feet daily in mugwort leaves can effectively treat athlete's foot and eliminate fungi.
