Distribution: Mainly in Chinese provinces such as Gansu. Mostly cultivated.

Harvest & Processing: Dig up roots after autumn, generally in the second year of cultivation; remove leaves, rootlets and soil; let stand to let the moisture inside evaporate briefly until the roots soften; tie into small bundles; dry slowly over low heat. Commonly used in Hong Kong in the form of length-wise cut slices of the top part or of the whole root.

Bark yellowish-brown to reddish-brown, marked with longitudinal wrinkles and lalongate (transversely elongated) lenticels; axial root thick and short, lower part with branch roots; branch roots thick at top part and tapering downwards, mostly twisted and marked with a few scars of rootlets. Soft and pliable; when broken, surface yellowish-white or pale yellowish-brown; cortex thick, marked with brown oil dots; cambium ring yellowishbrown; xylem lighter in colour, marked with radial markings; the core of broken surface of top part usually with pith and a cavity. Odour: heavily aromatic; taste: sweet, acrid and slightly bitter.
