Very dry skin can also mean you are very low in essential fats... which our bodies need to maintain flexibility and integrity.

Flax oil and fish oil help with this...and are also anti-inflammatory. There are smart foods now with flax oil added. Peanut butter even. Omega 3 eggs, Omega 3 spread butter substitute. You should be having salmon once a week at least. Supplements for these two oils are not expensive either.
WalMart has a good selection in fact even.

People with Candida in the bowel, can have thrush and/or vulvodynia symptoms.

The best natural way to fix this is to avoid sugar and white carbs in the diet (this starves the yeast), and use Kefir 4-6 oz daily to replenish good bacteria in your GI tract.

This is tons better than Chinese herbs IMO. Once you stabilize this your whole body will be much much better. A week on Kefir daily and you will be amazed!
