When I went to www.szpifu.com Futian Armed Police Hospital to treat onychomycosis, experts pointed out that I had a self-treatment for onychomycosis, which was very useful: I could add some apple vinegar to warm water and stir it evenly, then soak my nails in water for about 15-20 minutes, and then dry them completely. Tea tree oil can be used as a good medicine to treat onychomycosis, because it contains a natural preservative, which can help defeat a large number of fungi. Use some pure tea tree oil and mix a few drops of olive oil. Apply this mixed liquid to the infected nails.
