The thing that stands out to me about your post is that you are not having grains/starches in your diet and I think you were before. I know that from much experimenting in our family, we cannot handle grains/starches. If we do, symptoms gradually (after about 10 days) return. Yes, our diet is very boring (meats/eggs/steamed non-starchy veggies) but we are not on medications and are very much under control and lead a fairly normal life. We still have symptoms that I want to eradicate(i.e. mucous), but that is minor compared to being in a flare up all of the time. I would be very weary of the chinese herbal yam that you are eating.
