Vicks VapoRub can be used at home as a cure for toenail fungus, states Mayo Clinic. A small amount of the ointment can be applied to the affected toenails every day with a cotton swab.
Vicks VapoRub appears to have a positive impact in terms of the treatment of toenail fungus, according to a study published in the Journal of the American Board of Family Medicine. Out of 18 participants in the study, 15 had a positive outcome after treating toenail fungus with Vicks VapoRub. Five of the participants had their toenail fungus completely cured by the conclusion of the study; all 18 reported that they were satisfied or very satisfied with the effects of the Vicks VapoRub treatment.
