Abstract: Infections of toe nails and finger nails caused by fungi and yeast are treated topically by applying a liquid mixture of natural ingredients to the infected area. The mixture includes the essential oils of between about 10 and about 17 ml. of tea tree; between about 10 and about 17 ml. of lavender oil, and between about 1 and about 3.5 ml. of eucalyptus oil in a total of 30 ml. of liquid. All of the ingredients preferably are pharmaceutical grade for the best results. The liquid mixture is typically applied to the affected area once or twice a day for a period of at least two months until the infection is cured. A few drops of the composition can also be placed into the toe box of shoes and the toe portion of slippers when not being worn to prevent re-infection.
