Anything that gives you good bacteria culture is good. Yogurt is great, but besides that drink pomegranate juice and eat bananas. I assume you're talking about a yeast infection? You also need to buy one of those cure kits--they come in a box at a drugstore. There's a three day cure you can do which you basically put in like a tampon. It's super-easy.
Feel better!
