宁国府卫承务官只有一个儿子，忽然患病，身体消瘦得像被削过一样。医生认为是“瘵疾”（痨病），治疗没有效果。医生刘大用询问他得病的原因，他说：曾经在六月天喝醉后睡在桌子上，醒来时口渴想喝水，但前面没有水。看到前边有一个菖蒲盆里的水很清洁，就拿来喝了。从此以后疾病发作。
刘大用很高兴，秘密派遣仆人挖掘田间的淤泥，用水冲洗，取澄清的汁液两碗放在几案上，让病人随意饮用。卫家的儿子向来厌恶疾病的痛苦，不嫌弃脏秽，一饮而尽。不久，肠胃之间攻冲转动，搅动刺痛，很久才安定下来。接着又服用宣通大便的药物一百粒，随即剧烈腹泻，排出了六十多条水蛭。便觉得心胸豁然开朗。刘大用说：“这大概是误吞了盆中的水蛭。水蛭进入人的腹部，凭借膏血滋养，繁殖种类，常常粘附着五脏，牢固无法脱落。然而它长久生活在污渠中，思念它所嗜好的东西，不用这种物体引诱，它们不会聚集。但是身体虚弱，另外用药进行调补。”（出自《类编》）
有人因为醉酒，傍晚时分口渴，饮用了路边的田水。从此忽然患上胸腹胀满，遍访名医都没有效果，人们也不认识病因。他在客栈过夜，半夜想喝水，命令仆人去找。仆人在夜里摸索寻找，看见有几个缸，怀疑店主用来储水，于是取了一碗给他主人喝。便觉得胸中豁然开朗。再索取时，忽然觉得脏腑急迫，在店铺旁边的空地上大泻了一两次。天亮时查看，所排泄的是无数水蛭。接着看夜里所喝的缸里的水，原来是主人收割蓝草制作靛青的水。他的病立刻痊愈。方才想起之前口渴喝田水时，不觉误吞了水蛭在腹中，于是形成了胀痛的疾病。这是水蛭为害。现在的人耕田时被这种虫子咬伤，用靛青涂抹，没有不痊愈的。
赵子山，字景高，寓居在邵武军的天王寺，苦于寸白虫（绦虫）的骚扰。医生告诫说这个疾病应当戒酒，但他平时沉迷于此，想要戒除却做不到。一天晚上在外面喝醉回到住所，已经是半夜，口干咽燥，仓促间没有热水可饮。恰好走廊屋檐下有瓮水，在月光下照射显得晶莹可爱，就舀来喝。味道甘甜如糖，连喝了几勺就去睡觉。等到天亮，虫子排出铺满了席位，觉得心腹顿时宽松，宿疾于是痊愈。全家都感到惊异。验证其原因，原来是寺院的仆人每天编织草鞋，浸泡红藤根的水。（出自《庚志》）
The only son of Wei Chengwu from Ningguo suddenly fell ill, becoming emaciated as if carved away. Physicians diagnosed it as Zhai disease (consumption/tuberculosis), but treatment was ineffective. Physician Liu Dayou asked about the cause of his illness. He replied: "In June, I got drunk and slept on a table. Upon waking, I was thirsty for water but found none nearby. Seeing clean water in a pot of calamus (Acorus tatarinowii) ahead, I drank it. Since then, the illness manifested."
Liu Dayou was pleased and secretly sent a servant to dig up mud from the fields, wash it with water, and collect two bowls of clear liquid, placing them on a table for the patient to drink at will. The young master of the Wei family, weary of his suffering and indifferent to filth, drank it all at once. Soon, his intestines churned and twisted painfully before settling. Subsequently, he took one hundred pills of a purgative medicine (Xuan Yao), resulting in severe diarrhea, through which more than sixty leeches were expelled. He immediately felt a sense of relief in his chest and mind. Liu said, "This is likely due to accidentally swallowing leeches from the pot. Once leeches enter the human abdomen, they nourish themselves on bodily fluids and blood, reproducing and often adhering firmly to the five zang organs, making them difficult to dislodge. However, having lived long in dirty ditches, they crave their preferred environment; without such bait, they would not gather. Nevertheless, his body is weak, so other medicines should be used for regulation and tonification." (From *Lei Bian*)
Another person, after drinking heavily, quenched his thirst at dusk by drinking field water by the road. Thereafter, he suddenly suffered from chest and abdominal distension. Despite visiting many physicians, there was no effect, and no one could identify the cause. Staying overnight at an inn, he desired water at midnight and ordered a servant to find some. The servant searched in the dark, saw several jars, suspected the innkeeper stored water there, and brought a bowl to his master. Upon drinking, he felt immediate relief in his chest. Seeking more, he suddenly felt urgent pressure in his bowels and defecated profusely one or twice in a vacant area beside the shop. At dawn, he observed that what he had excreted was countless leeches. Inspecting the water from the jar he drank the previous night, he realized it was the water used by the owner to process indigo plants for dye production. His illness was instantly cured. He then recalled that when he had drunk the field water earlier, he must have inadvertently swallowed leeches into his abdomen, causing the distension and pain. This illustrates harm caused by leeches. Nowadays, people working in fields bitten by these insects apply indigo paste, which invariably cures them.
Zhao Zishan, courtesy name Jinggao, resided at Tianwang Temple in Shaowu Jun, suffering from torment by Cunbai chong (tapeworm). A physician advised him to abstain from alcohol, but being addicted, he could not stop. One night, he returned home drunk, past midnight, with a dry mouth and throat. Hastily finding no hot water, he noticed water in a jar under the eaves, glowing clearly under the moonlight. He scooped and drank it; it tasted sweet as syrup. After drinking several spoonfuls, he went to sleep. By morning, worms filled the mat where he had been lying, and he felt immediate relief in his heart and abdomen, curing his chronic ailment. The whole family was astonished. Investigating the cause, they found it was the water in which the temple servants soaked red vine roots (Spatholobus suberectus) daily to weave straw sandals.
