Direct yogurt remedy?

So I know yogurt is good for vaginal infections because of probiotics. I was told by a friend that instead of eating yogurt, to spoon it right into my vagina before bed as deep as possible. I mean; this isn't a terrible idea bc probiotic capsules anyone can put into their vagina instead of orally. I've done it. Soooo anyone hear of this, try this? Lol for infections.
