The correct name for Phellodendron Bark as a traditional Chinese medicine is Phellodendron Bark. Due to a variety of factors such as distributors, brands, and geographic regions, Phellodendron Bark does not have a uniform pricing, and the current price of 500g on the market varies from about 8~32 RMB. Because Huangbai is the dried bark of Phellodendron Bark or Phellodendron Bark in the family of Rutaceae, it is also known as Phellodendron Bark. Phellodendron Bark has a bitter taste and cold nature, and belongs to the kidney and bladder meridians. Its effects are clearing heat and drying dampness (removing heat and drying dampness), diarrhea and detoxification (removing fire and toxicity from the body), and removing bone vapor.
