古名桑蠹虫、又名桑蝎。宣、祛风。
甘温有毒。（时珍曰∶蝎化天牛有毒、蛴螬化蝉无毒、又可见蛴螬与蝎之性味良恶也。）
祛风
治障翳瘀肿。小儿惊风。口疮风疳。妇人崩中漏下赤白。堕胎下血。产后下痢。今人多用
以发痘。（景岳曰∶桑虫、亦名桑蚕、不知创自何人、用以发痘、予尝遍考本草及痘证诸书
、俱所不载、及审其质性、不过为阴寒湿毒之虫尔、惟其有毒、所以亦能发痘、惟其寒湿、
所以最能败脾、顾发痘不从气血、而从毒药、此与揠苗者何异、矧其淫毒侵脾、弱稚何堪、
故每见多服桑虫者、毒发则唇肤俱裂、脾败则泄泻不止、人但见痘证之死、而不知
其败在虫毒也、前之既覆、后可鉴矣、其奈蒙蒙者、率犹长夜之不醒何、予欲呼之、用斯代

元气为毒所伤、今人治痘无不用之、其为害不知若干人矣、吾盐冯
楚瞻、有锦囊秘录、其书庞杂浅鄙、全无足取、内有云∶大桑虫、有人参之功、噫、此黄口
小儿之言也、何物匪才、敢无知妄作耶。桑虫、即桑蠹虫、别录、日华、蜀本、藏器、时

Categories of hatching from transformation, hatching from eggs, etc.
Ancient name: Sangdu Chong (Mulberry Borer Insect); also known as Sang Xie (Mulberry Scorpion). Actions: Dispersing and expelling wind.
Sweet in taste, warm in nature, toxic. (Li Shizhen said: The scorpion transforms into the long-horned beetle (Tian Niu) and is toxic; the grub (Qi Lao) transforms into the cicada and is non-toxic. This shows the difference in nature and taste between Qi Lao and the scorpion.)
Expels wind.
Treats leukoma (visual obstruction due to corneal opacity), blood stasis, and swelling. Pediatric convulsions (Jing Feng). Mouth sores and wind-type malnutrition (Feng Gan). Women's metrorrhagia and metrostaxis with red and white discharge. Post-abortion bleeding. Postpartum dysentery. Nowadays, people mostly use it to induce smallpox lesions. (Zhang Jingyue said: Sang Chong, also called Sang Can [Mulberry Silkworm], I do not know who originated its use for inducing smallpox. I have thoroughly examined Bencao materia medica and various texts on smallpox, but none record this. Upon examining its nature, it is merely an insect of yin-cold-damp toxicity. Precisely because it is toxic, it can induce smallpox; precisely because it is cold and damp, it can most severely damage the Spleen. Moreover, inducing smallpox should proceed from Qi and Blood, yet here poisonous drugs are used. What is the difference from pulling shoots to help them grow? Furthermore, this excessive toxin invades the Spleen; how can young and weak children endure it? I often see that those who take too much Sang Chong suffer from cracked lips and skin when the toxin erupts, and unceasing diarrhea when the Spleen fails. People only see death from smallpox but do not realize it is caused by insect toxin. The previous tragedy has occurred; the future can serve as a warning. Alas, how can one deal with the ignorant who remain asleep through the long night? I wish to shout at them, using this as a watchman's clapper, and condemn the abominable originator of this practice. Wu Yiluo notes: Sang Chong can expel wind and penetrate collaterals; its nature is roughly similar to Shan Jian Jia (Pangolin Scales), thus both can injure Yuan Qi (Original Qi) via toxin damage. Nowadays, no one treats smallpox without using it; the harm caused is countless. My fellow townsman Feng Chuzhan wrote "Jinnang Milu" (Secret Records from the Brocade Bag). The book is verbose, shallow, and vulgar, entirely unworthy of adoption. It states: Large Sang Chong possesses the efficacy of Ren Shen (Ginseng). Alas, this is the talk of infants. Who, lacking talent, dares to act ignorantly and falsely? Sang Chong is indeed Sang Du Chong. "Bie Lu", "Ri Hua Zi", "Shu Ben", "Cang Qi", and "Shi Zhen" all recorded it. Why did Zhang Jingyue claim it was not recorded? However, none stated it treats smallpox, nor was it ever used in smallpox texts.) Chong Shi (Insect Feces), functions are roughly the same. Both should be calcined until carbonized but retaining their original properties, ground into powder, and mixed with wine. (Note: Niu Xi [Bovine Lice] suck blood; by analogy with Meng Chong [Horseflies], they are even less suitable for smallpox patients. Yet the world habitually uses them, causing great harm to many people.)
