Background

Chinese Name (pinyin): Quanshen

Chinese Name  :

Common Name  :Bistort Rhizome

Specific Name  : Rhizoma bistortae

Scientific Name:
Collection  : The drug is collected in early spring while the plant budding or in autumn just before withering, removed from soil, dried in the sun and removed from rootlet.

Description  : Compressed slat shaped or compressed cylindrical, curved both ends slightly sharp or tapering towards one end, some folded curved, 6 - 13 cm long, 1 - 2.5 cm in diameter. Externally purplish brown or purplish black, rough, prominent on one side and slightly even or slightly channeled on the other side with dense and rough annulations throughout and remains of rootlet or root scars. Texture hard, fracture pale brownish red or brownish red, vascular bundles yellowish white and pitted, arranged in a ring. Odourless, taste bitter and astringent

Identification  : 1.Powder: Pale brownish red, cork cells polygonal, containing brownish red contents. Clusters of calcium oxalate fairly abundant. 15 - 65 µm in diameter. Bordered pitted vessels 20 - 55 µm in diameter, reticulated in spiral vessels present as well. Fibres long fusiform 10 - 20 µm in diameter, walls relatively thickened, lignified with distinct pit canals. Starch granules ellipsoidal, ovoid or sub spheroidal, 5 - 12 µm in diameter.2.To 1 slice (or a small amount of powder), add 2 drops of ethanol and 1 drop of 1% solution of ferric chloride in ethanol, a bluish black colour is produced.Total ash: Not more than 8.0%

Processing  : Eliminate foreign matter, soak briefly, soften thoroughly, cut into thin slices and dry.

Action  : To remove toxic heat, to promote the subsidence of swelling, and to arrest bleeding.

Indication  : dysentery with bloody stools, diarrhea in acute gastroenteritis, acute respiratory infection with cough; carbuncles, scrofula, ulcers in the mouth and on the tongue; spitting of blood, epistaxis, hemorrhoidal bleeding, venomous snake bite

Precautions  :

Dosage  : 4.5 to 9 g; apropriate quantity for external use.

Storage  : Preserve in a dry place.
