Blogger Olga Boyko recalls the story of the summer she used Vicks VapoRub to cure the toenail fungus that afflicted her big toe. She showered and scrubbed the nail, then applied the medication, put a cotton sock over it, and went to sleep. In the morning after her shower, she tried to apply the medication again, but the infected portion of the nail started to peel off. “To this day, it’s the nastiest thing that has ever happened to me,” she wrote.
She reportedly applied the VapoRub anyway and continued to do so — twice a day — for several months. Despite the malady, she wore open-toe shoes to prevent fungus from taking hold inside damp, dark shoes. After three or four months, a healthy nail grew back. The internet is full of interesting stories like this one, alleging that Vicks VapoRub is an effective home remedy for toenail fungus. But is there any evidence backing this solution for a medical condition that is notoriously chronic and hard-to-treat?
