燥湿去风。
蚕只吃食物而不饮水，因此属性为火，性质燥烈。燥性能祛除风邪、胜除湿邪。（《内经》说：燥能胜风，燥属金，风属木。）蚕砂（家蚕的粪便）味辛、甘，性温。将其炒黄后浸泡在酒中饮用，可治疗风湿引起的疾病，如关节活动不利、皮肤顽固性麻木、腰脚冷痛、寒凝血瘀等。也可将蚕砂炒热后熨烫患处，效果也很好。（寇宗奭说：用三升纯酒拌五斗蚕砂，蒸热后铺在温暖房间的席子上，让患有风寒湿痹的人躺在上面，厚盖取汗，若未痊愈，第二天再做，但需防止患者昏闷。）用麻油调敷，可治疗烂弦风眼（眼睑边缘溃烂的眼病）。（上下眼睑属于脾，脾有风湿，则生虫导致眼睑边缘溃烂；另外用新瓦烧成粉末，少加雄黄，用麻油调敷，可治疗蛇串疮。有人食用乌梢蛇后，全身变黑，逐渐长出鳞甲，见者惊恐退缩，郑奠一让他每天服用晚蚕砂五钱，服完一两斗后，症状久之才消退。）这就是二蚕矢（即蚕砂）。淘洗干净晒干即可使用。
原蚕蛾（雄蚕蛾），气热，性欲旺盛。主要功效是固精强阳。（被毒蛇咬伤时，用生的二蚕蛾研碎外敷。）
斑蝥，又名斑猫。具有强烈的泻下作用，以毒攻毒。
味辛、寒，有毒。外用可腐蚀坏死组织，敷治疥癣和恶疮。内服可破除石淋（尿路结石），拔除瘰疬和疔肿。（杨登甫说：瘰疬的毒邪，无不有根，大致治疗以斑蝥、地胆为主，炮制方法得当，能使病根随小便排出，如粉片、血块、烂肉样物质，这是其疗效的验证，可用木通、滑石、灯心草等引导排泄。斑蝥被捕时，会放出臭不可闻的屁，所以专走下窍，直达精液和小便之处，能排出败坏之物，疼痛难忍，使用时必须斟酌。）排出犬毒。（这是一种九死一生的危重情况，急需用斑蝥七枚，去掉头、翅、足，用糯米炒黄后研末，用酒煎服，空腹服用，可排出小狗形状的毒物三四十枚，如果数量不够，再服用。另一方法：用糯米一勺，斑蝥二十一枚，分三次炒，直到冒出清烟为止，去掉斑蝥，取米研粉，用冷水加入少许清油，空腹服用，使毒物从大便排出，如果不排便，再进服。痊愈后，忌讳听到钟声和鼓声，否则复发则无法治愈。服药后肚子剧痛急迫者，用靛蓝汁或黄连水解毒。）腐蚀肌肉（肌肉靠近药物则腐烂）。堕胎。（斑蝥、芫青、葛上亭长、地胆，这四种虫外形不同，功效大致相近。吃芫花的是芫青，青绿色毒性尤大；春天生长吃葛花的是亭长，黑身赤头；夏天生长吃豆花的是斑蝥，身上有斑点；秋天生长冬天入地的是地胆，黑头赤尾。陶隐居说：这是一类生物在四季的变化，都极毒，必须谨慎。斑蝥，去掉头和足。用糯米炒熟。生用会引起呕吐腹泻。也有只用米取其气味，不取实质的用法。畏丹参、巴豆。恶豆花、甘草。）
Drying dampness and dispelling wind.
Silkworms feed but do not drink, thus belonging to the Fire nature which is dry. Dryness can dispel wind and overcome dampness. (The *Classic of Internal Medicine* states: "Dryness overcomes wind; dryness belongs to Metal, while wind belongs to Wood.") Cantharis powder (feces of the domestic silkworm) is pungent, sweet, and warm. When stir-fried until yellow and soaked in wine, it treats diseases caused by wind-dampness, such as immobility of joints, stubborn skin numbness, cold pain in the lower back and feet, cold blood stasis, and blood stasis. It can also be stir-fried hot and applied as a compress to the affected area, which is also effective. (Kou Zongshi said: "Mix three sheng of pure wine with five dou of cantharis powder, steam until hot, spread on mats in a warm room, have the patient suffering from cold-wind-damp bi syndrome lie on it, cover thickly to induce sweating. If not cured, repeat the next day, but beware of fainting or dizziness.") Mixed with sesame oil for topical application, it treats rotting margin wind-eye (blepharitis). (The upper and lower eyelids belong to the Spleen; when the Spleen has wind-dampness, parasites may grow causing the margins to rot. Additionally, calcining new tiles into powder, adding a small amount of Realgar, and mixing with sesame oil treats herpes zoster. Someone who consumed *Zaocys dhumnades* turned black all over and gradually developed scales, terrifying those who saw him. Zheng Dianyi instructed him to take five qian of evening cantharis powder daily; after consuming one or two dou, the symptoms eventually subsided.) This is Er Can Shi (Cantharis powder). Wash clean and sun-dry.
Original Silkworm Moth (male silkworm moth), its Qi is hot and its nature is lustful. It primarily secures essence and strengthens yang. (For snake bites, use raw Er Can Mo, grind and apply externally.)
Bing Lang, also known as Ban Mao. A strong purgative, using toxicity to attack toxicity.
Pungent, cold, and toxic. Externally used to escharotic dead tissue, applied for scabies, tinea, and malignant sores. Internally used to break stone strangury (urinary calculi), and to draw out scrofula and carbuncles. (Yang Dengfu said: "The toxicity of scrofula invariably has a root. Generally, treatment focuses on Bing Lang and Di Dan. With proper processing, it can cause the root to exit via urination, appearing like powder flakes, blood clots, or rotten flesh; this is the verification of its efficacy. Use Tong Cao, Hua Shi, and Deng Xin Cao to guide the flow. When captured, Bing Lang excretes a foul-smelling gas from its anus, hence it specifically targets the lower orifices, reaching the seat of essence and urine, capable of expelling corrupt matter, causing unbearable pain. Its use requires careful consideration.") Expels dog venom. (This is a critical condition where nine out of ten die. Urgently use seven pieces of Bing Lang, remove head, wings, and legs, stir-fry with glutinous rice until yellow, grind into powder, decoct in wine, and take on an empty stomach. It will expel 30-40 small dog-shaped toxins. If insufficient, administer again. Another prescription: One spoon of glutinous rice and twenty-one pieces of Bing Lang, stir-fry in three portions until clear smoke appears, discard the Bing Lang, take the rice powder, mix with cold water and a little refined oil, take on an empty stomach to purge toxins via stool. If no purging occurs, administer again. After recovery, avoid hearing bells and drums; if relapse occurs due to these sounds, it becomes incurable. If severe abdominal pain occurs after ingestion, use Indigo juice or Coptis chinensis decoction to detoxify.) Eschars muscle (muscle rots upon contact). Abortifacient. (Bing Lang, Yuan Qing, Ge Shang Ting Chang, and Di Dan are four insects with different appearances but similar functions. Those eating Yuan Hua are Yuan Qing, greenish-blue and highly toxic; those born in spring eating Ge flowers are Ting Chang, black body with red head; those born in summer eating bean flowers are Bing Lang, spotted; those born in autumn and hibernating in winter are Di Dan, black head with red tail. Tao Hongjing stated: "These are transformations of one type of organism across the four seasons, all extremely toxic, requiring caution." Bing Lang, remove head and legs. Stir-fry with glutinous rice until cooked. Raw use causes vomiting and diarrhea. Some use only the aroma extracted by rice, not the substance itself. It fears Danshen and Ba Dou. It clashes with Dou Hua and Gan Cao.)
