Yogurt. If you put some greek plain yogurt on a tampon. It sounds gross but it really does help.

Take acidophilus capsules (it's the ingredient in yogurt that 'fights' the yeast), or eat yogurt if you prefer not to go direct with the yogurt - I've heard some people say the topical yogurt treatment works, others say not at all, and I've never tried it personally.

I didn't find inserting yogurt to help. You can insert garlic cloves. That helps, but you'll taste garlic in your mouth the whole time. Strange but true how those two body parts are connected.

You can also google making your own boric acid pills that are supposed to be quite effective.

I don't bother with home remedies myself. I go straight to my gyn for prescription stuff.

I use the acidophilus pills too, work well for me.

I've used the unsweetened yogurt too, topically and orally, and it did seem to help. I've also added a couple drops of tea tree oil to the topical application to help with the itching, but it does sort of burn/tingle a bit. I used to get yeast infections in college when I got stressed and wasn't getting enough sleep, downing coffee/caffeine in order to stay awake at night to finish my work. Cutting out the caffeine and sugar, getting plenty of sleep, and drinking unsweetened cranberry juice seemed to help as well.

Yeast infections tend to occur when the fungus, yeast, becomes the dominant organism in and around your vaginal canal. Usually, the bacteria that live there kind of keep it in check. Often, the balance is shifted due to a change in the pH of the canal. So, what tend to help is to determine what caused the change (often dietary). Otherwise, taking an acidophilus (Acidophilus is a group of bacteria) supplement will help "replenish" the "good bacteria" and they will begin to fight back the yeast.

However, eating yogurt or other dairy products that contain acidophilus is rather ineffective because as you ingest the yogurt, the unprotected bacteria tends to be killed in your stomach. As mentioned, though, you can put yogurt directly on the vaginal opening. Keep in mind, though, that yeast can digest the yogurt so it may not work. You would be adding good bacteria while also feeding the yeast.

I recommend the supplement.

Vinegar and salt bath. Vinegar is a known to naturally balance out the P.h of the skin. It's what they use to bathe burn victims to help with the itching and healing.

Baking soda in the bath helps too.
