Home remedies for treating fingernail fungus include keeping the nails trimmed and thin and using over-the-counter antifungal nail creams and ointments, states Mayo Clinic. In one study, 56 percent of participants experienced improvement in their condition by applying Vicks VapoRub once daily.
Applying urea cream overnight and covering it with a bandage softens the nail and makes trimming and thinning easier, notes Mayo Clinic. Repeating the process over several nights may be necessary. Softening the nail also aids treatment by allowing medicine to penetrate deeper into the nail bed.
Alternative methods for treating nail fungus include snakeroot extract and tea tree oil, according to Mayo Clinic.
