The first place to start is to remove the cause of the yeast infection and this usually means reducing sugar and simple carb consumption, stop taking antibiotics, and to take a candida cleanse to remove the damage caused by antibiotics.

To alleviate the symptoms, one cause use a douch dipped in a mixture of 2 tablespoons to one quart water.  Apple the douch twice a day until the burning and itchiness disappears.  Careful not to apple the douch too often as experts say this can cause complications.  Another trick is to bath in apple cider vinegar (about one cups worth).

It is not uncommon for women to misdiagnose their yeast infection when in fact they have a bacterial infection or STD.  If it is a yeast infection, in general anti-fungal agents will do the trick.

Eating yogurt can be very helpful because it can restore the priobitics needed to wipe out the yeast infections.  Some even suggest using yogurt douches. 

Boric acid is another cure for yeast infections but this is very controversial.  Herbs that help include goldenseal, tea tree oil, and garlic.  Garlic is a great natural antifungal agent and in fact some women go so far as to use garlic douches for their infections.
