（宋《开宝》）
【释名】石僵蚕（《纲目》）。
【集解】志曰∶石蚕生海岸石旁，状如蚕，其实石也。
【气味】苦，热，无毒。《药诀》曰∶苦，热，有毒。独孤滔曰∶制丹砂。
【主治】金疮止血生肌，破石淋血结，磨服，当下碎石（《开宝》）。
（《纲目》）
【集解】时珍曰∶石鳖生海边，形状大小俨如 虫，盖亦化成者。 虫，俗名土鳖。
【气味】甘，凉，无毒。
【主治】淋疾血病，磨水服（时珍）。
（《唐本草》）
【集解】恭曰∶蛇黄出岭南，蛇腹中得之，圆重如锡，黄黑青杂色。
志曰∶蛇黄多赤色，有吐出者，野人或得之。
颂曰∶今越州、信州亦有之。今医所用，云是蛇冬蛰时所含土，到春发蛰吐之而去，大
如弹丸，坚如石，外黄内黑色，二月采之。与旧说不同，未知孰是？
时珍曰∶蛇黄生腹中，正如牛黄之意。世人因其难得，遂以蛇含石代之，以其同出于蛇
故尔。广西平南县有蛇黄冈，土人九月掘下七、八尺，始得蛇黄，大者如鸡子，小者如弹丸，
其色紫。《庚辛玉册》云∶蛇含自是一种石，云蛇入蛰时，含土一块，起蛰时化作黄石，不
稽之言也。有人掘蛇窟寻之，并无此说。

(Song Dynasty *Kaibao Bencao*)
[Names] Shi Jiangcan (Stone Silkworm) (*Bencao Gangmu*).
[Collection and Explanation] Su Song stated: Shi Can grows beside rocks on the coast. Its shape resembles a silkworm, but it is actually stone.
[Flavor and Properties] Bitter, hot, non-toxic. *Yaojue* states: Bitter, hot, toxic. Dugu Tao stated: It can moderate the toxicity of Cinnabar (Zhusha).
[Indications] Stops bleeding and promotes tissue regeneration for traumatic wounds; breaks up lithiasis (Shi Lin) and blood stasis. When ground and ingested, it facilitates the expulsion of kidney stones (*Kaibao Bencao*).
(*Bencao Gangmu*)
[Collection and Explanation] Li Shizhen stated: Shi Die grows by the sea. Its shape and size are exactly like the earth beetle (Tu Bie), likely formed through transformation. The earth beetle is commonly known as Tu Bie.
[Flavor and Properties] Sweet, cool, non-toxic.
[Indications] Treats strangury (Lin Ji) and bloody diseases. Grind into water and ingest (Li Shizhen).
(Tang Dynasty *Xinxiu Bencao*)
[Collection and Explanation] Su Gong stated: She Huang (Snake Gallstone) originates from Lingnan. It is found in the snake's abdomen, round and heavy like tin, with mixed colors of yellow, black, and green.
Su Song stated: She Huang is mostly reddish. Some have been vomited out, and wild people sometimes obtain them.
Su Song further stated: They are now also produced in Yuezhou and Xinzhou. The ones currently used by physicians are said to be soil contained by snakes during hibernation, which they expel when waking up in spring. They are as large as a pellet, hard as stone, yellow outside and black inside, harvested in February. This differs from older accounts, and it is unknown which is correct.
Li Shizhen stated: She Huang forms within the snake's abdomen, similar to the principle of Niu Huang (Cow Bezoar). Because She Huang is rare, people substitute it with She Han Shi (Ophicalcite), as both are associated with snakes. In She Huang Gang, Pingnan County, Guangxi, locals dig seven or eight feet deep in September to find She Huang. Large ones are egg-sized, small ones pellet-sized, and their color is purple. *Gengxin Yuce* claims that She Han Shi is a distinct stone, formed when a snake holds soil during hibernation which turns into yellow stone upon awakening. This is unverified talk. Those who dug snake burrows found no evidence of this.
[Processing] Chen Zangqi stated: For medicinal use, calcine until red, quench in vinegar three to four times, grind into powder, and process using the water levigation method.
[Flavor and Properties] Cold, non-toxic.
[Indications] Treats heart pain, Zhuwu (a type of infectious or mental disorder), lithiasis, pediatric convulsions and epilepsy, and difficult labor in women. Boil in water, grind, and ingest the juice (*Tang Bencao*).
Calms the heart and spirit (Chen Zangqi). Grind into juice and apply topically to swellings and toxins (Li Shizhen).
[Attached Prescriptions] Six new prescriptions.
An Feng Xian Ji (Hidden Wind Epilepsy): Sudden collapse, loss of consciousness, recovering after a long time. Take She Huang, calcine red, quench in vinegar seven times, and grind into powder. Mix with wine and take two qian per dose. Several doses cure it. Effective even for chronic cases. (Wei Shi *Defang Fang*)
Jing Feng Xian Gan (Convulsive Wind, Epilepsy, and Infantile Malnutrition): Shenxue Dan: Treats acute convulsive wind, epilepsy, Tian Diao (upward deviation of eyes/head), and Gan Re (malnutrition heat). Use four liang of purple She Huang (calcined), two liang of pig feces (small ones sealed with mud and calcined), one liang of Ferrum Preparatum (Tiefen), half a liang of Cinnabar (Zhusha), and one qian of Moschus (Shexiang). Grind into powder, make pills the size of Euryale seeds using glutinous rice paste, and dry in a lacquer tray. Each pill has a small hole, hence the name Shenxue Dan. Take one pill per dose, dissolved in mint wine, for immediate recovery. For Gan Re, dissolve in cold water. (*Lingyuan Fang*)
