Common natural remedies used to treat yeast infections at home include garlic, tea tree oil, probiotic supplements and yogurt, and boric acid suppositories, according to Everyday Health. One problem with natural home remedies is sufficient clinical trial evidence doesn't back up their effectiveness.
Boric acid suppositories have the potential to treat yeast infections, notes Everyday Health. Supplements and yogurt that contain beneficial bacteria known as Lactobacillus might possibly be useful in treating as well as preventing yeast infections, but any evidence that may support this claim is often inconsistent. While some evidence shows that tea tree oil can be effective in treating yeast infections in animal models, tests have yet to show it can be used to treat yeast infections in humans.
Prescription and over-the-counter medications used to treat yeast infections include ointments, tioconazole, anti-fungal creams, miconazole, medicated tampons and clotrimazole, Everyday Health states. Some medications have been known to cause vaginal burning and itching or make such symptoms worse. Depending on the type of medication, yeast infections can be fully treated anywhere from one to seven days after taking medication. A strong azole oral medication or fluconazole can be taken in a single dose for women who desire a fast-acting yeast infection treatment.
