治虫啮腹痛，作止有时，或耕起来往（腹痛有作止者，虫啮则痛，不啮则止也。气耕往
来
大黄（炒，两半） 鹤虱（炒） 槟榔 诃子皮 芜荑（炒） 木香 干姜（炒） 附
子（七钱
此足阳明药也。虫喜温恶酸而畏苦，故用姜、附之热以温之，乌梅、诃子皮之酸以伏之
，大黄、槟榔、芜荑、鹤虱之苦以杀之，木香辛温以顺其气也。
治腹痛胃痛，干痛有时干痛者，不吐不泻而但痛也；有时者，淡食而饥则痛，浓味而饱
则否，此为虫也。
雄黄 槟榔 白矾，等分。饭丸。每五分，食远服。
此手足阳明药也。雄黄之辛毒，槟榔之苦降，白矾之酸涩，皆杀虫之品也，故合用以治
之。
治肠胃诸虫为患肠（胃之中无物不容，所以变生诸虫者，缘正气虚衰，或误食生虫之物，
或湿热蒸郁而成，亦犹物必先腐而后虫生之义也）。
鹤虱 胡粉（炒） 苦楝根（东引未出土者） 槟榔（一两）芜荑 使君子（五钱） 枯
矾（二
此手足阳明药也。数药皆杀虫之品也，单用尚可治之，类萃为丸，而虫焉有不死者乎（吴
鹤皋曰∶古方杀虫，如雷丸、贯众、干漆、蜡矾、百部、铅灰之类，皆其所常用者也。有加
附子、干姜者，壮正气也；加苦参、黄连者，虫得苦而伏也；加乌梅、诃子者，虫得酸而软
也；加藜芦、瓜蒂者，欲其带虫吐出也；加芫花、黑丑者，欲其带虫泻下也；用雄黄、川椒、
蛇床、樟脑、水银、槟榔者，治疮疥之虫也；用胡桐泪、莨菪子、韭子、蟾酥者，治龋齿之
虫也；用川槿皮、海桐皮者，治风癣之虫也；用青葙子、覆盆叶者，治九窍 蚀之虫也；用
败鼓心；桃符板、虎粪骨、死人枕、獭爪、鹤骨者驱劳瘵之虫也）。
（出自《三因极一病证方论》）
治疗虫咬引起的腹痛，疼痛发作和停止都有定时。所谓“耕起来往”（指腹痛时作时止，是因为虫子咬动则痛，不咬则停；气机运行往来），大黄（炒制，一两半）、鹤虱（炒制）、槟榔、诃子皮、芜荑（炒制）、木香、干姜（炒制）、附子（七钱）。
这是足阳明胃经的药物。虫子喜欢温暖、厌恶酸味且畏惧苦味，所以用干姜、附子的热性来温煦它，用乌梅、诃子皮的酸味来制约它，用大黄、槟榔、芜荑、鹤虱的苦味来杀灭它，用木香的辛温之性来顺调气机。
治疗腹痛胃痛，有时出现干痛（所谓干痛，是指不呕吐、不腹泻，只是单纯疼痛；所谓有时，是指吃清淡食物感到饥饿时疼痛，吃浓味食物吃饱后就不痛，这是寄生虫病的表现）。雄黄、槟榔、白矾，各等分。做成饭丸。每次服用五分，在饭后较远的时间服用。
这是手足阳明经的药物。雄黄的辛毒，槟榔的苦降，白矾的酸涩，都是杀虫的药物，所以合用它们来治疗此病。
治疗肠胃各种寄生虫为患（胃中有东西容纳，所以能变生各种寄生虫，原因是正气虚弱衰败，或者误食了带有虫卵的东西，或者湿热蒸腾郁结而成，这也如同物体必须先腐烂然后才生虫的道理一样）。鹤虱、胡粉（炒制）、苦楝根（向东生长未出土的部分）、槟榔（一两）、芜荑、使君子（五钱）、枯矾（二两）。
这是手足阳明经的药物。这些药物都是杀虫的品种，单用还可以治疗，汇集同类药物制成丸剂，那么虫子哪有不死掉的道理呢？（吴鹤皋说：古方中杀虫的药，如雷丸、贯众、干漆、蜡矾、百部、铅灰之类，都是他们常用的。有的加入附子、干姜，是为了壮盛正气；加入苦参、黄连，是因为虫子遇到苦味就会伏藏；加入乌梅、诃子，是因为虫子遇到酸味就会软化；加入藜芦、瓜蒂，是想让虫子随着呕吐排出；加入芫花、黑丑，是想让虫子随着泻下排出；使用雄黄、川椒、蛇床、樟脑、水银、槟榔，是治疗疮疥的虫子；使用胡桐泪、莨菪子、韭子、蟾酥，是治疗龋齿的虫子；使用川槿皮、海桐皮，是治疗风癣的虫子；使用青葙子、覆盆叶，是治疗九窍蚀烂的虫子；使用败鼓心、桃符板、虎粪骨、死人枕、獭爪、鹤骨，是驱除劳瘵的虫子。）
(From *San Yin Ji Yi Bing Zheng Fang Lun*)
Treats abdominal pain caused by worm bites, where the pain occurs and ceases at specific times. The term "geng qi lai wang" (referring to intermittent abdominal pain: pain arises when worms bite and ceases when they do not; reflecting the movement of Qi) is addressed with Dahuang (Stir-fried, 1.5 liang), Leshe (Stir-fried), Binglang, Hezi Pi, Wuyi (Stir-fried), Muxiang, Ganjiang (Stir-fried), and Fuzi (7 qian).
This prescription targets the Foot Yangming channel. Worms favor warmth, dislike sourness, and fear bitterness. Therefore, the heat of Ganjiang and Fuzi is used to warm them; the sourness of Wu Mei and Hezi Pi is used to subdue them; the bitterness of Dahuang, Binglang, Wuyi, and Leshe is used to kill them; and the acrid-warm nature of Muxiang is used to regulate Qi.
Treats abdominal and stomach pain characterized by dry pain occurring intermittently. "Dry pain" refers to pain without vomiting or diarrhea; "intermittent" means pain occurs when hungry after eating light food, but does not occur when full after eating rich food. This indicates a parasitic condition. Xionghuang, Binglang, and Baifan are mixed in equal proportions. Formed into pills using rice paste. Take 5 fen per dose, administered well after meals.
This prescription targets the Hand and Foot Yangming channels. The acrid toxicity of Xionghuang, the bitter descending nature of Binglang, and the astringent sourness of Baifan are all substances that kill parasites; thus, they are combined to treat this condition.
Treats various gastrointestinal parasitic infestations. (The stomach accommodates all manner of substances, which can give rise to parasites due to deficiency and decline of righteous Qi, ingestion of items containing parasite eggs, or steaming and stagnation of damp-heat. This follows the principle that an object must first rot before worms can grow within it.) Leshe, Hufen (Stir-fried), Kuligen (East-growing, ungerminated roots), Binglang (1 liang), Wuyi, Shijunzi (5 qian), and Kufan (2 liang) are used.
This prescription targets the Hand and Foot Yangming channels. These drugs are all agents for killing parasites. They can be effective even when used singly; however, gathering similar agents into a pill form ensures that parasites will inevitably die. (Wu Hegao stated: Ancient formulas for killing parasites commonly used substances such as Leiwuan, Guanzhong, Ganqi, Lafan, Baibu, and Qianhui. Some formulas add Fuzi and Ganjiang to strengthen righteous Qi; add Kushen and Huanglian because parasites are subdued by bitterness; add Wu Mei and Hezi because parasites are softened by sourness; add Lili and Gouti to expel parasites via vomiting; add Yuanhua and Heichou to expel parasites via purgation; use Xionghuang, Chuanjiao, Shechuangzi, Zhangnao, Shuiyin, and Binglang to treat parasites causing sores and scabies; use Hutonglei, Langdangzi, Jiuizi, and Chansu to treat parasites causing dental caries; use Chuanjinpi and Haitongpi to treat parasites causing wind-xuan; use Qingxiangzi and Fupenyè to treat parasites eroding the nine orifices; use Baiguxin, Taofuban, Hufen gu, Siren zhen, Tazhao, and Hegu to drive out parasites causing consumption/labor disease.)
