Apple cider vinegar is an effective treatment for toenail fungus, according to Dr. Michael Shapiro of Vanguard Dermatology in New York City. Apple cider vinegar treats external signs of Candida, including yeast and fungal infections, Natural News reports.
The acidic nature of apple cider vinegar creates an inhospitable environment for fungus without being strong enough to damage the surrounding skin and nail. Apple cider vinegar can be applied directly to the affected area or diluted in a bath; however, it may cause a burning sensation when applied directly to the skin. Wellness Mama recommends a solution of one part apple cider and four parts water.
