Will fungus on the toenail be cured permanently with tea tree oil?

Doubt it.: Possible distal mycosis of the nail edge may benefit from tea tree oil but generally the tea tree oil is used as a vehicle from antifungual medications.

Maybe?: The reason you hear so many different treatments for toenail fungus is because there is no perfect, sure-fire treatment that works 100% of the time. I've seen vaporub work, as well as other natural oil remedies, but rarely. You can also try laser therapy, antifungal creams, paints, or even oral medications if your doctor deems you healthy enough to take them.
