Is there a natural cure/preventative for female yeast infections?

Best prevention: Is to avoid what causes yeast to overgrow in the body - eating sweets, eating a lot of carbs, fruit juice, soda pop and alcohol. Also wearing clothes around the vagina that don't breath increase chance of yeast, as does taking antibiotics. Eating yogurt or other foods with live cultures can help - make sure it's a yogurt low in carbs. Boric acid in the vagina, such as in yeast arrest might help.
