9. Olive leaf extract
Olive leaf extract contains oleuropein, which is a natural antifungal and antimicrobial. A salve made from the olive leaf can be applied to the toenails to reduce infection. You may also swallow capsules containing the extract to boost the immune system and treat toenail fungus systemically. Approximately two olive leaf extract capsules can be taken twice a day for an extended period. Consult your doctor before taking olive leaf extract.
