Drink cranberry juice. If you have a mild yeast infection or suspect that you may be developing one, drink 8 oz (250 ml) of cranberry juice several times a day for a mild treatment. Cranberries lower the pH of urine. As the urine passes over some of the infected vaginal area, it alters the overall pH of the area, thereby creating conditions more conducive to fighting yeast infections. Cranberry pills or dried cranberries can also be used instead of the juice.
