吴少师在关外尝得疾数月间肌肉消瘦每日饮食下咽少时腹如万虫 攻且痒且痛皆以为劳
瘵也
张锐是时在成都吴遣驿骑招致锐到兴元既切脉戒云明日早且忍饥勿啖一物俟锐来为之计旦而
往天方剧暑白请选一健卒趋往十里外取行路黄土一银盂而令厨人旋治面将午乃得食才放箸取
土适至于是温酒二升投土搅其内出药百粒进于吴饮之觉肠胃掣痛几不堪忍急登溷锐密使别坎
一穴便掖吴以行须臾暴下如倾秽恶斗许有马黄千余宛转盘结其半已困死吴亦惫甚扶憩竹榻上
移时方餐粥一器三日而平始言去年正以夏夜出师中涂躁渴命候兵持马盂挹涧水甫入口似有物
焉未暇吐之则径入喉矣自此遂得病锐曰虫入人肝脾里势须滋生常日遇食时则聚丹田间吮咂精
血饱则散处四肢苟惟知杀之而不能扫尽故无益也锐是以请公枵腹以诱之此虫喜酒又久不得土
味乘饥毕集故一药能洗空之耳吴大喜浓赂以金帛送之归(庚志)
心部的虫叫做蛔虫，脾部的虫叫做寸白虫，肾部的虫像截断的一寸长的丝线，肝部的虫像腐烂的杏子，肺部的虫像蚕。这些虫都能致人死亡，其中肺部的虫最为急迫。肺虫居住在肺叶之内，侵蚀人的肺系，因此形成痨瘵（慢性消耗性疾病），出现咯血、声音嘶哑的症状。药物难以到达病所，治疗非常困难。有人说《道藏》中记载各种虫都是头朝下的，只有从农历初一至初五之前，它们头向上行，所以用药的人大多取用初五之前的月相（指月亮位置或时间），大概就是这个原因吧。例如治疗寸白虫，使用良方中的锡沙、芜荑、槟榔效果极佳，在五更天服用，虫子能全部排出，之后喝白粥调养。药用石榴根浓汁半升，送服散剂三钱或丸药五枚。（出自《本事方》）
九种虫分别是：第一种叫伏虫，长四分，是群虫的首领；第二种叫白虫，长一寸，相互滋生数量极多，其母体长到四五丈就会杀人；第三种叫肉虫，形状像腐烂的杏子，让人烦闷胀满；第四种叫肺虫，形状像蚕，让人咳嗽；第五种叫胃虫，形状像蛤蟆，让人呕吐逆气、干呕呃逆；第六种叫弱虫，形状像瓜瓣，让人多唾沫；第七种叫赤虫，形状像生肉，让人肠鸣；第八种叫蛲虫，极其微小细长，形状像菜虫，居住在直肠之间，多了就会导致痔漏、痈疽等各种疮疡无所不为；第九种叫蛔虫，长一尺，贯穿心脏就会杀人。另外还有尸虫，与人同时出生，形状像犬马尾巴或薄筋，依附在脾脏居住，长约三寸左右，对人危害很大。然而这多是因为脏腑虚寒、劳热而产生的。
能进入耳朵的虫类，不仅仅是蜒蚰（蜗牛/蛞蝓），还有壁虱、萤火虫、扣头虫、皂角虫等，都能造成危害。有人患脑痛被虫啃食，有人教他用桃叶做枕头，一夜之间虫子从鼻子出来，形状像鹰嘴，人们不认识它的名字。有人遇到蜒蚰进入耳朵，在极度难受时，用头撞柱子直到流血都不知道疼痛，说是痒得不可忍受。蜒蚰进入耳朵往往把骨髓吃尽，又能滋生繁殖。凡是虫子进入耳朵，用生油灌入效果很好。（出自《遁斋闲览》）
吴少师在关外曾经患病，几个月间肌肉消瘦，每天饮食咽下不久，腹部就像有万虫攻咬，又痒又痛，大家都认为是劳瘵病。张锐当时在成都，吴派驿骑邀请他。张锐到了兴元，诊脉后告诫说：“明天早晨务必忍住饥饿，不要吃任何东西，等我来了再想办法。”第二天早上前往，当时正值酷暑，张锐请求选一名健壮的士兵，跑到十里外取来路上黄土，用一个银碗，让厨师现场和面。快到中午才做好食物，刚放下筷子取土，土正好送到。于是温酒二升，投入黄土搅拌在其中，取出药丸一百粒让吴服用。吴喝完觉得肠胃牵拉疼痛，几乎不能忍受，急忙去厕所。张锐秘密让人挖了一个坑，搀扶着吴去排便。不一会儿，吴猛烈腹泻，倾泻出污秽恶臭物约一斗，其中有马黄虫一千多条，宛转盘结，一半已经困死。吴也疲惫不堪，扶着他躺在竹榻上休息，过了一会儿才吃了一碗粥，三天后痊愈。吴这才说起去年夏天夜晚出兵，中途烦躁口渴，命令士兵拿着马盂舀涧水，刚入口好像有东西，没来得及吐出来就径自吞入喉咙了。从此就得了这个病。张锐说：“虫进入人的肝脾内部，势必会滋生。平时遇到吃饭时候就聚集在丹田间吮吸精血，吃饱了就分散到四肢。如果只知道杀虫而不能扫尽，所以没有益处。”张锐因此请吴空腹以引诱它们。这种虫喜欢酒，又很久没有得到土味，趁着饥饿全部聚集，所以一种药就能把它们洗空干净。吴非常高兴，用大量的金银绢帛赠送给他，送他回去。（出自《庚志》）
The parasite of the Heart meridian is called Hui Chong (Ascaris); that of the Spleen meridian is Cun Bai Chong (Taenia solium, tapeworm); that of the Kidney meridian resembles a one-cun long piece of cut silk thread; that of the Liver meridian resembles a rotten apricot; and that of the Lung meridian resembles a silkworm. All these parasites can cause death, but the Lung parasite is the most urgent. The Lung parasite resides within the lung lobes, eroding the lung system, thus forming Zhai Ji (consumption/tuberculosis), characterized by hemoptysis (coughing up blood) and hoarseness. Medicines cannot easily reach the site of the disease, making treatment difficult. It is said that in the Daoist Canon (Dao Zang), it is recorded that all parasites have their heads pointing downwards, except from the first to the fifth day of the lunar month, when they move with their heads upward. Therefore, those using medicine often take advantage of the moon phase before the fifth day, which is likely the reason. For example, to treat Cun Bai Chong, using Xisha (Tin Sand), Wuyi (Chrysanthemum indicum fruit), and Binglang (Areca Seed) from the Liang Fang prescription is excellent. Taken at Wu Geng (3-5 AM), the parasites will be completely expelled, followed by nourishing with white congee (Rice Porridge). (From *Ben Shi Fang*)
The so-called Nine Parasites are: 1. Fu Chong (Hidden Worm), four fen long, the leader of the group of worms; 2. Bai Chong (White Worm), one cun long, capable of reproduction, multiplying greatly, and if its mother grows to four or five zhang, it causes death; 3. Rou Chong (Flesh Worm), resembling a rotten apricot, causing irritability and fullness; 4. Fei Chong (Lung Worm), resembling a silkworm, causing cough; 5. Wei Chong (Stomach Worm), resembling a toad, causing vomiting and regurgitation; 6. Ruo Chong (Weak Worm), resembling melon seeds, causing excessive salivation; 7. Chi Chong (Red Worm), resembling raw meat, causing borborygmus (bowel sounds); 8. Tiao Chong (Pinworm), extremely minute and fine, resembling vegetable worms, residing in the large intestine, causing hemorrhoids, fistulas, carbuncles, and various sores when numerous; 9. Hui Chong (Roundworm), one chi long, piercing the heart causes death. There is also Shi Chong (Corpse Worm), born with humans, resembling a dog or horse tail or thin fascia, residing attached to the Spleen, about three cun long, causing great harm. However, these parasites mostly arise due to deficiency-cold of the Zang organs and heat from overwork.
Parasites that can enter the ear are not limited to Yan You (Slug). Bi Shi (Bedbug), Ying Huo (Firefly), Kou Tou Chong (Head-bobbing insect), and Zao Jiao Chong (Soap pod insect) can all cause harm. One person suffered brain pain eaten by parasites; someone advised using Peach Leaf (Tao Ye) as a pillow, and overnight the parasite exited through the nose, shaped like an eagle's beak, unrecognizable to people. Another person had a slug enter his ear; at the peak of discomfort, he hit his head against a pillar until bleeding occurred without feeling pain, claiming the itching was unbearable. Slugs entering the ears often consume the marrow entirely and can reproduce. For any parasite entering the ear, pouring raw oil is effective. (From *Dun Zhai Xian Lan*)
Minister Wu suffered from illness while in the Guanwai region for several months, losing muscle mass. Shortly after swallowing food daily, his abdomen felt as if ten thousand insects were attacking, causing both itching and pain. Everyone believed it was Lao Zhai (Consumption). Zhang Rui was then in Chengdu. Minister Wu sent an express rider to summon him. Upon arriving in Xingyuan, Zhang Rui took his pulse and warned: "Tomorrow morning, endure hunger and do not eat anything. Wait for me to devise a plan." The next morning, upon arrival, the weather was intensely hot. Zhang Rui requested a strong soldier to run ten li away to fetch road soil, using a silver bowl, and instructed the cook to prepare dough on the spot. By noon, the food was ready. Just as he put down his chopsticks to get the soil, it arrived. Zhang Rui then mixed two sheng of warm wine with the soil, extracted one hundred pills, and administered them to Minister Wu. After drinking, Minister Wu felt severe pulling pain in his intestines and stomach, barely tolerable, and hurried to the latrine. Zhang Rui secretly ordered a pit to be dug and supported Minister Wu to walk for a moment. Suddenly, he experienced violent diarrhea, expelling foul matter worth about one dou, containing over a thousand Ma Huang Chong (likely Ascaris or similar intestinal worms), coiled and knotted, half of which were dead. Minister Wu was exhausted, rested on a bamboo couch for a while, and then ate a bowl of congee. He recovered in three days. He later stated that last summer night, during troop deployment, he was thirsty and ordered soldiers to scoop stream water into a horse basin. As soon as he drank, he felt something inside but did not have time to spit it out, swallowing it directly. This led to the illness. Zhang Rui said: "When parasites enter the interior of the Liver and Spleen, they inevitably multiply. Usually, during meal times, they gather in the Dan Tian to suck essence and blood; when full, they disperse to the limbs. If one only knows how to kill them but cannot eradicate them completely, it is of no benefit." Thus, Zhang Rui asked Minister Wu to fast to lure them. These parasites favor wine and, having lacked earth flavor for a long time, gathered together while hungry, allowing one dose of medicine to cleanse them entirely. Minister Wu was overjoyed, gifted him gold and silk, and sent him home. (From *Geng Zhi*)
