Probiotic treatments from drug stores are great, but yogurt seems to be a winner.
Use a plain yogurt with active cultures (the acidophilus helps your body’s pH levels return to normal) in it. This will provide you with a cooling sensation also to combat the itching and burning. Wash the area twice a day with warm water before applying the yogurt, but DO NOT use soap unless it is a mild, hypo-allergenic such as "Summer's Eve"
To take the yogurt a step further, add 2 drops of tea tree oil, which kills yeast and bacteria (and 1 drop lavender - optional). Mix this in 1/2 cup of yogurt, mix, and use a vaginal applicator / plastic syringe to insert the yogurt into the vagina. You can also use an applicator out of a Monistat package or something. Just like with a normal cream, lay down directly after inserting the yogurt.
Use the yogurt mixture for about 4 days AFTER symptoms subside. Probably a total of 10 days. Its a long process but you can still have the yeast overgrowth with NO symptoms. If at that point you stop treating it, you could create a more resistant infection.
If symptoms do not subside, seek medical attention. This is not something you want to play around with.
****Be sure that you use pure, therapeutic grade essential oil. These are plant extracts with therapeutic properties. If you use a fragrance oil, you may further aggravate the problem. Also try to cut excess sugar from your diet and add an unsweetened cranberry juice. This will help treat the current infection as well as prevent future ones. Also eat pro-biotic yogurt.
