How to treat yeast infections in the vagina by home remedies?

Several over-the-counter vaginal creams or suppositories work well. Look for products with active ingredient ending in "azole" (miconazole, clotrimazole and others). You can choose the least expensive; they all work equally well. Be sure you have typical yeast symptoms (mostly itching/irritation, not much discharge or odor). See a doctor if in doubt or if treatment doesn't work.
