Traditional remedies for athlete's foot include tea tree oil or crocodile oil in a topical application on the affected area. Users report instant relief from itching allowing lesions to heal. Proponents of urine therapy claim that urine is very effective at killing athlete's foot. Urea, the "active ingredient" in urine, is already used in many drugs and treatments made by pharmaceutical companies to treat athlete's foot. This controversial treatment method recommends urinating on the infected area once a day in the shower. According to supporters, urine therapy not only kills existing fungi, it prevents new fungi from growing in the infected area.
One biochemist states that urea is only used to soften the outer layers of skin so that antifungal drugs can reach fungi below the surface, and that the urea must be concentrated and applied for a long period of time in order to be effective. According to another article about high-concentration urea cream, the compound is used to "dissolve proteins and [as a] denaturant. The ability of urea to macerate [tissue] has been attributed to a 'proteolytic effect', but others attribute the maceration to the hydrating properties of urea." This use requires a high concentration of urea, up to 40%, and extended exposure. Urea itself without the presence of an additional antifungal drug is not referred to in scholarly literature as having antifungal properties. Thus, it is unlikely that urinating on one's feet in the shower will significantly improve a case of athlete's foot.
