Similarly, it is asked, does urine really kill athlete's foot?
Some people say urine might cure athlete's foot because of the urea that it contains. It would have to be a very large amount of urea (more than how much is normally found in urine) for it to be considered useful to treat tinea pedis (“athlete's foot”). So in reality, no, it probably does not work.
Keeping this in view, does urine cure toenail fungus?
Urine contains urea, which is used at high concentrations to remove fungus-infected toenails (Dermatology, online, May 2013). The concentration of urea in urine is far weaker, but we have heard similar stories from other readers. It may take months of foot soaks to get rid of nail fungus.
Oral antifungal drugs. These drugs are often the first choice because they clear the infection more quickly than do topical drugs. Options include terbinafine (Lamisil) and itraconazole (Sporanox). These drugs help a new nail grow free of infection, slowly replacing the infected part.
