Yeast infections are caused by a fungus called Candida albicans and can occur in the vagina, mouth, stomach skin or urinary tract. Both olive leaf extract and grapefruit seed extract products are sold as antimicrobials to fight off various infections, including yeast infections. However, both olive leaf extract and grapefruit seed extract have potentially serious side effects, so consult your doctor before taking either to treat a yeast infection.
Olive Leaf Extract
You can take 250 mg to 500 mg of olive leaf extract three times daily as an antifungal, according to the University of Maryland Medical Center, or UMMC. Since a yeast infection is caused by a fungus, olive leaf may prove helpful in fighting if off. However, the UMMC does not specifically state that olive leaf extract can fight off yeast infections. A study published in “Mycoses” in April 2003 showed olive leaf extract capable of working as an antimicrobial with the ability to kill off Candida albicans in vitro. The results were promising but not definitive, however.
