Magnolia Officinalis is derived from the dry skin, bark and root bark of Magnolia Plant. Dry skin is either reel or double drum.
The outer surface is gray-brown or grayish brown and rough, and the cork is sometimes flaky flake, with obvious oval holes and longitudinal wrinkles; the shave is brown and flat. The inner surface is smoother, purple-brown or dark purple-brown, with fine longitudinal lines and marked oil marks. The quality is hard and it is not easy to break. The outer section is gray-brown and granular, purple-brown or brown inside, rich in oil, and sometimes shows most of the shining fine crystals (magnolol crystallization). The fragrance is not bitter with the bitter taste.
Root bark: a single cylinder or irregular piece, some split, some curved like “Chicken Intestines”. The surface is grayish brown with transverse stripe and longitudinal wrinkles. It is hard and easy to break.
Branched skin: single tubular, thinner. The surface is gray-brown and wrinkled. Hard, easy to break, cross-section fibrous.
