吴少师忽得疾。数月间。肌肉消瘦。每饮食下咽。少时腹如万虫攒攻。且痒且痛。皆以
为
劳瘵也。张锐为切脉。戒曰。明日早。且忍饥。勿啖一物。吴如其言。时方剧暑。令取行路
黄土一盂。以温酒二升。投土搅匀在内。使吞之。少顷。再以土酒送宣药百粒。随即肠胃掣
痛。洞泻秽恶斗许。有马蝗千余。宛转盘结。俱已困死。吴亦惫甚。卧久方餐粥。三日而平
始言去年夏夜出师。中途燥渴。命候兵持孟挹涧水。甫入口。似有物。未暇吐之。则竟入
喉矣。自此遂得病。锐曰。虫入肠胃里。势渐滋生。常日遇食时。则聚丹田间。吮咂精血。
饱则散而四处。苟惟知杀之而不能扫尽。无益也。故请枵腹以诱之。此虫喜酒。又久不得土
味。乘饥毕集。乃可以一药洗空之耳。
震按水蛭生于淤泥。故以其所嗜者诱使聚而攻下之巧矣。然有人饮刈蓝作靛之水而蛭亦
泻出。更觉简便。及读灵兰要览。附载一条云。余于幼时。见水蛭。恶而溺之数四。化为水
又一日见之。滴以蜜一匙。即缩不动。久之亦化为水。嗣后虽经阴雨而不复活。二物之制
蛭如此。而昔人有吞蛭者。医者治之。乃极劳扰。惜乎其不知此也。观金坛之说。笑鸡峰之
张皇矣。震以为抵当丸用蜜丸。或仲景又先见及此耶。
金庄一农夫。夏天昼寐于地。蜈蚣入其口。既寤。喉仲介介如梗状。咯不能出。咽不能
下。痛痒不定。甚为苦楚。一医以鸡卵数枚劈破。入酒调匀。顿服。仍以大黄为末。和香油
饮之。顷刻泻出。蜈蚣尚活。盖蜈蚣被鸡卵拘挛其足。不能舒动。以利药下之。故从大便而
出。鸡性好食蜈蚣。亦取相制之意耳。

吴少师突然患病。几个月间，肌肉消瘦。每次饮食咽下后，不一会儿腹部就像有上万只虫子聚集攻击一样，又痒又痛。大家都认为是劳瘵（虚劳咳嗽，类似结核病）。张锐为他切脉，告诫说：“明天早晨，务必忍受饥饿，不要吃任何东西。”吴少师照他的话做了。当时正值酷暑，张锐让人取来一盂行路黄土，用二升温酒倒入土中搅匀，让吴少师吞服。过了一会儿，再用这“土酒”送服宣药一百粒。随即肠胃剧烈掣痛，排出大量恶臭秽物约一斗多，其中有一千多条马蝗（水蛭），宛转盘结在一起，都已困死。吴少师也极度疲惫，躺了很久才喝粥，三天后才痊愈。事后吴少师说，去年夏天夜晚出兵，中途口渴燥热，命令哨兵拿着碗去舀涧水。刚入口时，似乎有东西，来不及吐出，就竟吞入喉中了。从此便得了这个病。张锐说：“虫子进入肠胃里，势力逐渐滋生。平常遇到进食时，它们就聚集在丹田之间，吮吸精血。吃饱了就散开四处活动。如果只知道杀虫而不能彻底清扫干净，是没有益处的。所以请求空腹以引诱它们。这种虫子喜欢酒味，又长久没有尝到土的味道，趁着饥饿全部聚集过来，才能用一种药物将它们彻底清除干净。”
俞震按语：水蛭生于淤泥之中，所以用它所喜好的东西引诱它聚集，然后攻下，这是巧妙的办法。然而有人喝了制作蓝靛的刈蓝水，水蛭也被泻出出来，更觉得简便。等到读《灵兰要览》时，附录记载一条说：“我小时候，看见水蛭，厌恶它而连吐了四次，它化为水；又一天看见它，滴上一匙蜜，它就缩住不动，很久也化为水。此后虽然经过阴雨天气也不会复活。这两种方法制服水蛭如此有效，而过去有人吞下水蛭，医生治疗起来，极其劳苦扰攘，可惜他们不知道这些方法啊。看金坛的说法，嘲笑鸡峰山人（陈自明）的夸张荒诞了。我认为抵当丸使用蜜丸，或许是张仲景又预先想到了这一点吧。”
金庄有一个农夫，夏天白天睡在地上，蜈蚣爬进他的嘴里。醒来后，喉咙感觉不适，像是有异物梗塞，咳不出来，咽不下去，疼痛瘙痒不定，非常痛苦。一个医生用几个鸡蛋打破，加入酒调匀，让他一次服下。仍然用大黄研成粉末，和香油一起饮用。顷刻间泻出，蜈蚣还活着。大概是因为蜈蚣被鸡蛋拘挛了它的脚，不能舒展活动，再用泻下的药物推动它，所以从大便排出。鸡性喜欢吃蜈蚣，也是取相克制的意思罢了。
村口店铺的一位妇人用火筒吹火，不知道筒内藏着蜈蚣，受惊窜入她的喉咙，一直下到胸膈。妇人求救无措。恰好有路过的人，教她宰杀一头小猪，取猪血让妇人一次性喝下。一会儿，用生油灌入妇人一口，妇人感到恶心，那蜈蚣滚在血中被吐出来。随后给予雄黄细细研磨，用水调服，痊愈了。
一个人突然患脑痛，有时停止有时发作，多次发作却不知原因。有一天快到中午吃饭时，趴在案子上睡觉，旁边正好有一盘鸡肉。梦中忽然打喷嚏，觉得有东西从鼻子里出来，一看，原来是蚰蜒（一种多足节肢动物）在鸡肉上。从此脑痛不再发作。蚰蜒形状像蜈蚣但更细，喜欢钻进人的耳朵，往往吃人的脑髓，脑髓吃尽人就会死亡。北方很多地方都有。
Shao Shi Wu suddenly fell ill. Over the course of several months, his muscles wasted away. Whenever food and drink were swallowed, shortly thereafter his abdomen felt as if tens of thousands of insects were swarming and attacking, causing both itching and pain. Everyone believed it to be Lao Zhai (consumptive disease, similar to tuberculosis). Zhang Rui took his pulse and warned him: "Tomorrow morning, endure hunger; do not eat a single thing." Wu followed his instructions. At that time, it was the height of summer heat. Zhang Rui ordered someone to fetch one bowl of yellow earth from the road, pour two sheng of warm wine into it, stir well, and have Wu swallow the mixture. A short while later, he administered one hundred pills of Xuan Yao using this "earth-wine" as a vehicle. Immediately afterwards, severe pulling pain in the intestines and stomach ensued, followed by the profuse discharge of foul-smelling excrement, approximately one dou in volume. Among them were over a thousand leeches, coiled and knotted together, all exhausted and dead. Wu was also extremely debilitated; he lay down for a long time before consuming congee, and recovered after three days. Wu then recounted: "Last summer night, while leading troops, I suffered from thirst and dryness midway. I ordered a scout to fetch stream water with a bowl. As soon as it entered my mouth, I sensed an object but had no time to spit it out, so it went down my throat. Since then, I have been suffering from this illness." Zhang Rui said, "When insects enter the intestines and stomach, their influence gradually multiplies. On ordinary days when food is ingested, they gather around the Dantian field, sucking essence and blood. When full, they scatter and move about. If one only knows how to kill them but cannot sweep them all out, it is of no benefit. Therefore, I requested an empty stomach to lure them. These insects favor the taste of wine and have long lacked the taste of earth. Taking advantage of their hunger, they gathered in large numbers, allowing a single medicine to cleanse them completely."
Yu Zhen commented: Leeches are born in silt, so luring them with what they crave and then purging them downward is a clever method. However, some people expelled leeches after drinking water used for making indigo dye from Isatis root, which seems even simpler. Upon reading *Ling Lan Yao Lan*, an appendix recorded a case stating: "In my youth, upon seeing a leech, I was disgusted and vomited four times until it turned into water. Another day, seeing one, I dripped a spoonful of honey on it; it contracted and became immobile, eventually turning into water. Even after subsequent rainy weather, it did not revive. These two methods effectively control leeches. Yet, in the past, when someone swallowed a leech, physicians' treatments were extremely laborious and disruptive. It is a pity they did not know these methods. Judging by the account from Jintan, one might laugh at Chen Ziming's exaggeration. I believe that the use of honey pills in Didang Wan might indicate that Zhang Zhongjing anticipated this earlier."
A farmer in Jin Zhuang slept on the ground during a summer day. A centipede entered his mouth. Upon waking, he felt discomfort in his throat, as if obstructed by a foreign body; he could neither cough it out nor swallow it down. The pain and itching varied, causing great distress. A physician instructed him to break several eggs, mix them evenly with wine, and consume them in one dose. He was then given rhubarb powder mixed with sesame oil to drink. Within moments, he defecated, and the centipede was still alive. This was likely because the egg whites caused the centipede's legs to contract, preventing movement, and the purgative effect facilitated its expulsion via the large intestine. Chickens naturally prey on centipedes, reflecting the principle of mutual restraint.
A woman at a village shop was blowing fire with a bamboo tube, unaware that a centipede was hidden inside. Startled, it scurried into her throat and descended to her chest. Desperate for help, she found herself at a loss. Fortunately, a passing traveler advised her to slaughter a piglet, collect its blood, and have her drink it all at once. Shortly after, he poured a mouthful of raw oil into her mouth, inducing nausea. The centipede rolled in the blood and was vomited out. Subsequently, she was treated with finely ground realgar mixed with water, and she recovered.
A person suddenly suffered from headaches that came and went intermittently without a known cause. One day, just before noon mealtime, he fell asleep leaning on a desk. A plate of chicken meat happened to be nearby. In his dream, he sneezed suddenly and felt something exit through his nose. Upon inspection, it was a house centipede (*Scutigera coleoptrata*) on the chicken meat. Thereafter, his headaches ceased. House centipedes resemble centipedes but are thinner; they often enter human ears and may consume brain marrow. If the marrow is fully consumed, death ensues. They are common in northern regions.
