Common Name  :Black Snake

Specific Name  : Zaocys

Scientific Name:
Collection  : The drug is collected in autumn and summer, cut open in the abdomen or open after the skin is stripped except the head and tail skin, remove from the viscera, coiled up in disc shape and dried.

Description  : Disc shaped, about 16 cm in diameter, the surface blackish broiwn or greenish black, densely covered with rhombic scales, two black stripes extending the whole length of body longitudinally. Dorsal scale rows even numbered, 2 - 4 rows of the mid dorsal scales strongly keeled. The head in the center of the disc, flattened rounded. Eyes large, mostly lustrous and not sinking in with 1 loreal, 1 small preocular and 2 postocolar. The median dorsal portion towering like roof ridge. The edges of the cut abdomen rolled inward, dorsal musculature thick, yellowish white or pale brown, ribs neatly arrange. The tail long and gradually tapering. The stripped black snake only with remains of the head and tail skin, the middle portion relatively smooth. Odour stinking and taste weak.

Identification  :

Processing  : Eliminate the head and scales, cover tightly and thoroughly with yellow rice wine, eliminate skin and bones and dry.Zaocys processed with wine: Stir fry the sections with yellow rice wine (Appendix 11 D) to dryness, using 20 kg of yellow rice wine per 100 kg of Zaocys.

Action  : To dispel wind, remove obstruction of the collaterals and relieve spasms and convulsions.

Indication  : chronic rheumatoid arthritis with numbness and ankylosis; hemiplegia in stroke; convulsion, tetanus, leprosy, scabies, scrofula with suppuration

Precautions  :

Dosage  : 9 to 12 g.
