Order 3-6 bottles. I would try the huanglian first, and if you do not see satisfactory results try the longdan.
These are chinese herbs. They work to balance organs/conditions within the body. In terms of FBO/BB, this arises from damp heat in the liver/large intestine. You need to purge the heat from these areas. Also, you need to eat a diet with a lot of steamed veggies, complex carbs, fruit, etc. Very low fat. Pretty much a vegan diet needs to be followed. NO DAIRY OR ALCOHOL specially. Chinese herbs work on a deep level, but unlike western medicine they work slowly. You should begin seeing results after about two weeks, but it may take 1-3 months to drain all the damp heat, assuming you are following the diet.
