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

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

化生类、卵生类等。
味甘，性温，有毒。（李时珍说：天牛由蝎变化而来，所以有毒；蛴螬变化为蝉，所以无毒；由此可以看出蛴螬与蝎的性味有良恶之分。）
祛风。
治疗目生障翳、瘀血肿痛。小儿惊风。口疮、风疳。妇人崩漏、赤白带下。堕胎后下血。产后痢疾。现在的人多用来发痘疹。（张景岳说：桑虫，也叫桑蚕，不知道是谁首创用它来发痘疹，我曾遍查本草及痘证方面的书籍，都没有记载。等到审视它的质地性质，不过是阴寒湿毒之虫罢了。正因为有毒，所以也能发痘；正因为性寒湿，所以最能败坏脾胃。况且发痘疹应当从气血入手，却使用毒药，这与拔苗助长有什么区别呢？何况这种淫毒侵犯脾胃，年幼体弱的孩子怎么能承受得住？所以我经常见到服用桑虫过多的人，毒气发作时嘴唇和皮肤都开裂，脾胃败坏则泄泻不止。人们只看到痘证导致的死亡，却不知道是败在虫毒上。以前的教训已经惨痛，后面的可以借鉴了，无奈那些蒙昧无知的人，就像长夜不醒一样，我想呼喊他们，用这代替打更的梆子，并谴责始作俑者的可恨。吴仪洛按语：桑虫能祛风且走窜经络，其性质大约与穿山甲相近，所以都能损伤元气被毒所伤。现在人治痘疹无不用它，造成的危害不知有多少人。我的同乡冯楚瞻，有《锦囊秘录》这本书，内容庞杂浅薄鄙陋，完全不值得取法。书中说：大桑虫，有人参的功效。唉，这是黄口小儿的话，什么东西没有才能，敢如此无知妄作呢？桑虫，就是桑蠹虫，《别录》、《日华子本草》、《蜀本草》、《本草拾遗》、《本草纲目》都收录了，为什么张景岳认为没有记载呢？只是它们并没有说它能治痘疹，痘证方面的书籍，也从未有用过它的。）虫矢（桑虫的粪便），功用大致相同。都要烧存性研成末，用酒调服。（按：牛虱吸食血液，例子比虻虫更甚，尤其不适合痘疹患者使用，而世间习惯使用它，伤害的人很多了。）

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.)
