Does it work to put yogurt in my vagina to get rid of a yeast infection?

Yes: However, a much better choice would be to eat the yogurt rather than using it as a douche. The bacteria will get into your gastrointestinal tract and by proximity at the rear end, will also get where you want it to go - much less messier too. Another alternative is an otc product called luvena that supposedly has probiotics that is designed to be a vaginal insert.
