You can cure toenail fungus or fingernail fungus completely with a product that you can buy at most health food stores. It is called Tea Tree Oil (yes there is such a plant as a tea tree)and it comes in a bottle with a dropper or an applicator. Just put it on the affected nail top and bottom, cover and re-apply every day until the fungus is gone. It may take a month or two to completely eradicate it and to grow healthy nails, but it definitely works. We have tried it successfully several times. Tea Trea Oil is an excellent anti-fungal and anti-bacterial product. Just make sure that it is pure Tea Tree Oil and not a mixture of things. The brand we used in the USA was Desert Essence, but there are many other brands around in the store that will probably work just as well. Just be patient and use it every day (preferably at night so you can wear a sock over it).
