Vinegar diluted with water is commonly used to treat fungal nail infections.
Vinegar is able to fight and kill these fungi because of its high acidity. Soak your nails in a vinegar and water solution every night and you will see the changes in approximately three to six months. A variation of the vinegar foot bath is a mixture of one liter of dark beer at room temperature, a liter of white vinegar and a half sachet of acidophilus.
The feet of the affected person should be soaked in this mixture for at least thirty minutes a day for a period ranging from one to three months. It is very important to remember that the feet and the affected nails should be dried completely after every session so as to enhance speedy treatment because fungi tend to worsen in a moist environment.
