常仲明，病湿痹，五、七年矣。戴人令上涌之后，可泄五、七次。其药则舟车、
浚川、通经、神 、益肾，自春及秋，必十余次方能愈。公之病，不必针灸，与令嗣皆宜涌
，但腊月非其时也。欲候春时，恐予东适。今姑屏病之大势，至春和时，人气在上，可再涌
之，以去其根。卒如所论矣。
又 一衲子，因阴雨卧湿地，一半手足皆不随，若遇阴雨，其病转加。诸医皆作中风偏枯治之
，用当归、芍药、乳香、没药、自然铜之类，久反大便涩，风燥生，经岁不已。戴人以舟车
丸下三十余行，去青黄沫水五升；次以淡剂渗泄之，数日，手足皆举。戴人曰∶夫风湿寒
之气，合而成痹。水湿得寒，而浮蓄于皮腠之间，久而不去，内舍六腑。曰∶用去水之
药可也。水湿者，人身中之寒物也。寒去则血行，血行则气和，气和则愈矣。
又 息帅，病腰股沉痛，行步坐马皆不便。或作香港脚寒湿治之，或作虚损治之，乌、附、乳、
没，活血壮筋骨之药，无不用之。至六十余日，目赤上热，大小便涩，腰股之病如故。戴人诊其
两手脉，皆沉迟。沉者为在里也。在里者泄之。以舟车丸、浚川散，各一服，去积水二十余
行。至早晨，服齑白粥一二顿，与之马，已能矍铄矣。
又 棠溪李十八郎，病腰脚大不伸，伛偻蹩HT 而行，已数年矣。服药无效，
止药却愈。因秋暮涉水
，病复作。医氏使服四斤丸。其父李仲安，乃乞药于戴人。戴人曰∶近日服何药？仲安曰∶
四斤丸。曰∶目昏赤未？其父惊曰∶目正暴发！戴人曰∶宜速来，不来则丧明。既来则策杖
而行，目肿无所见。戴人先令涌之，药忽下走，去二十行，两目顿明，策已弃矣。比再涌泄
，能读官历日。调至一月，令服当归丸，健步而归家矣。
又 息城边校白公，以隆暑时饮酒，觉极热，于凉水池中渍足，使其冷也。为湿所中，股膝沉
痛。又因醉卧湿地，其痛转加。意欲以酒解痛，遂以连朝而饮，反成赤痛，发间止，且六十
年。往往断其寒湿香港脚，以辛热治之，不效。或使服神芎丸数服，痛微减。他日复饮，疾作
如前。睾囊痒湿且肿硬，脐下似有物，难于行，以此免军役，令人代之，来访戴人。戴人曰∶余亦
断为寒湿。但寒则阳火不行，故为痛；湿则经隧有滞，故肿。先以苦剂涌之，次以舟车丸
百余粒，浚川散四、五钱，微一、两行。戴人曰∶如激剂尚不能攻，何况于热药补之乎？
又用神 丸百二十丸，通经散三、四钱，是用，仅得四行。又来日，以神 八十丸投之，
续见一、二行。又次日，服益肾散四钱，舟车丸百余粒，约下七、八行。
白公已觉膝睾寒者暖，硬者软，重者轻也。肿者亦退，饮食加进。又以涌之，其病全瘳。临
别，又赠之以疏风丸，并以其方与之。此公以其不肯妄服辛热药，故可治也。
常仲明患有湿痹，病程已有五到七年。张从正（戴人）让他先进行涌吐治疗，之后可以泄下五到七次。所用的药物包括舟车丸、浚川散、通经散、神芎丸、益肾散，从春季持续到秋季，必须经过十多次治疗才能痊愈。他的病不需要针灸，他和他的儿子都适合涌吐法，只是腊月不是合适的时机。担心等到春天时，我（张从正）将向东出行。现在暂且搁置对病情大势的判断，等到春天气候温和时，人体阳气上升，可以再行涌吐，以去除病根。最终果然如他所预测的那样。
又有一位僧人，因为阴雨天气睡在潮湿的地方，导致一半的手脚不能随意活动，如果遇到阴雨天气，病情就会加重。各位医生都将其作为中风偏枯来治疗，使用当归、芍药、乳香、没药、自然铜之类的药物，时间久了反而导致大便干结涩滞，风燥内生，一年多了病情没有好转。张从正用舟车丸泻下三十多次，排出青黄色的泡沫水五升；接着用淡渗利湿的药物进行渗泄治疗，几天后，手脚都能抬举了。张从正说：风湿寒之气，结合而成痹证。水湿遇到寒气，就浮聚蓄积在皮肤腠理之间，久了不去，内侵六腑。《内经》说：可以用去水的药物治疗。水湿是人身体中的寒性物质。寒气去除则血液运行通畅，血液运行通畅则气机调和，气机调和则病愈了。
又有一位息帅，患有腰部和股部沉重疼痛，走路和骑马都不方便。有人将其作为香港脚（足胫重肿酸痛之病）寒湿来治疗，有人将其作为虚损来治疗，乌头、附子、乳香、没药等活血壮筋骨的药物，没有不用的。到了六十多天，出现眼睛发红、上部发热，大小便涩滞，腰股部的病痛依旧。张从正诊察他两手脉象，都是沉迟脉。沉脉表示病在里。病在里的应当用泄法。于是给他服用舟车丸、浚川散各一次，排出积水二十多次。到了早晨，吃一两顿醋拌白粥，给他马骑，他已经能精神矍铄地行动了。
又有一位棠溪李十八郎，患有腰脚严重伸展不利，弯腰跛行，已经好几年了。服药无效，停药反而痊愈。因为秋末涉水，病情复发。医生让他服用四斤丸。他的父亲李仲安，于是向张从正求药。张从正问：最近服用了什么药？李仲安说：四斤丸。张从正问：眼睛昏花发红吗？李仲安惊讶地说：眼睛正好突然发作红肿！张从正说：应该赶快过来，不来就会失明。来了之后，他拄着拐杖行走，眼睛肿胀什么都看不见。张从正先让他涌吐，药力下行，排出二十行，双眼顿时明亮，拐杖也扔掉了。再次涌吐泄下后，他能阅读官方的日历了。调理一个月后，让他服用当归丸，健步走回家去了。
又有一位息城边校白公，在酷暑时节饮酒，感觉极热，就在凉水池中浸泡双脚，使其冷却。被湿气所伤，大腿膝盖沉重疼痛。又因为醉酒睡在潮湿地方，疼痛加剧。本想用酒来解痛，于是连续几天饮酒，反而成了赤痛，发作间歇停止，长达六十年。往往断定为寒湿香港脚，用辛热药物治疗，无效。或者让他服用神芎丸几次，疼痛稍微减轻。第二天再饮酒，疾病像以前一样发作。阴囊瘙痒潮湿且肿胀坚硬，肚脐下好像有东西，难以行走，因此免除军役，让人代替他，来拜访张从正。张从正说：我也断定为寒湿。但是寒气则阳气火气不行，所以疼痛；湿气则经络隧道有阻滞，所以肿胀。先用苦味药剂涌吐，然后用舟车丸一百多粒，浚川散四、五钱，微微腹泻一、两行。张从正说：如果激越的药剂尚且不能攻邪，何况用热药补益呢？又用神芎丸一百二十丸，通经散三、四钱，服用后，仅仅得到四次排便。第二天，用神芎丸八十丸投喂，继续见到一、两次排便。第三天，服用益肾散四钱，舟车丸一百多粒，大约排泄七、八行。
白公已经觉得膝盖和阴囊寒冷的变温暖，坚硬的变柔软，沉重的变轻了。肿胀也消退，饮食增加。又用涌吐法，他的病完全痊愈。临别时，又送给他疏风丸，并把方子给他。这位先生因为他不肯乱服辛热药物，所以可以治愈。
Chang Zhongming suffered from Bi syndrome due to dampness (Bi syndrome caused by dampness pathogen), a condition persisting for five to seven years. Dai Ren instructed him to undergo emesis (emetic therapy) first, followed by purgation (purgative therapy) five or seven times. The medications used included Zhouche Wan (Zhouche Pill), Xunchuan San (Xunchuan Powder), Tongjing San (Tongjing Powder), Shenxiong Wan (Shenxiong Pill), and Yishen San (Yishen Powder). From spring to autumn, more than ten treatments were necessary for recovery. His condition did not require acupuncture and moxibustion; both he and his son were suitable candidates for emesis, though the twelfth lunar month was an inappropriate time. Fearing that I would travel eastward by the time spring arrived, we temporarily set aside the assessment of the disease's major trend. When the weather became mild in spring, when human Qi rises, we could perform emesis again to eliminate the root cause. This prediction ultimately came true.
Another case involved a monk who, after sleeping on a damp floor during rainy weather, lost movement in half of his limbs. His condition worsened with rainy weather. Various physicians treated him as hemiplegia due to wind-stroke (Wind-Stroke causing Hemiplegia), using herbs such as Danggui (Angelicae Sinensis Radix), Shaoyao (Paeoniae Radix), Ruxiang (Olibanum), Moyao (Myrrha), and Ziran Tong (Pyritum). Prolonged use resulted in constipation and dryness, generating internal Wind-Dryness, with no improvement over a year. Dai Ren administered Zhouche Wan for purgation more than thirty times, expelling five sheng of yellow-green frothy fluid. Subsequently, he used bland diuretic herbs to promote fluid metabolism (diuresis). Within a few days, the patient regained movement in his limbs. Dai Ren stated: Wind, cold, and dampness combine to form Bi syndrome. Water-dampness, encountering cold, floats and accumulates between the skin and interstices. If it persists, it invades the Six Fu Organs internally. As stated in the classics: "Medicines that remove water should be used." Water-dampness is a cold substance within the body. Once cold is removed, blood circulation improves; once blood circulates freely, Qi harmonizes, and healing occurs.
Another case involved Xi Shuai, who suffered from heavy, painful sensations in the waist and thighs, making walking and horseback riding difficult. Some physicians treated him as Hong Kong Jiao (Hong Kong Foot, characterized by heaviness and swelling of the lower legs) due to cold-dampness, while others treated him as deficiency damage. Medications such as Wutou (Aconiti Lateralis Radix Praeparata), Fuzi (Aconiti Radix Praeparata), Ruxiang, and Moyao—herbs that invigorate blood and strengthen bones and tendons—were all utilized. After sixty-plus days, he developed red eyes and upper-body heat, along with difficulty in urination and defecation, while the waist and thigh pain remained unchanged. Dai Ren palpated his pulses at both wrists, finding them deep and slow. A deep pulse indicates an interior condition. For interior conditions, purgation is indicated. He administered one dose each of Zhouche Wan and Xunchuan San, resulting in more than twenty evacuations of accumulated fluid. By morning, after consuming one or two meals of vinegar-mixed white porridge and riding a horse, he appeared vigorous and agile.
Another case involved Li Shibalang from Tangxi, who had suffered for several years from severe inability to extend his waist and legs, walking stooped and limping. Medication proved ineffective, but stopping medication led to recovery. However, wading through water in late autumn triggered a relapse. Physicians prescribed Sijin Wan (Sijin Pill). His father, Li Zhongan, sought treatment from Dai Ren. Dai Ren asked, "What medicine have you taken recently?" Li Zhongan replied, "Sijin Wan." Dai Ren asked, "Are your eyes dim and red?" Li Zhongan exclaimed in surprise, "My eyes have suddenly become severely swollen!" Dai Ren said, "Come immediately; otherwise, you will lose your sight." Upon arrival, Li walked with a cane, his eyes so swollen he could see nothing. Dai Ren first induced emesis. The medicinal action moved downward, resulting in twenty evacuations, and his vision cleared instantly; he discarded his cane. After subsequent emesis and purgation, he could read official calendars. After one month of regulation, he took Danggui Wan (Danggui Pill) and returned home walking briskly.
Another case involved Officer Bai from Xicheng, who drank alcohol during intense summer heat, feeling extremely hot, and soaked his feet in a cold pool to cool down. He was affected by dampness, suffering from heavy pain in his thighs and knees. Sleeping drunk on a damp floor exacerbated the pain. Attempting to relieve the pain with alcohol, he drank continuously for several days, which transformed the condition into red, painful swelling, occurring intermittently for sixty years. It was often diagnosed as cold-damp Hong Kong Jiao and treated with acrid-hot herbs without effect. Taking Shenxiong Wan a few times slightly reduced the pain, but drinking again caused the disease to recur as before. His scrotum was itchy, damp, swollen, and hard; there was a sensation of a mass below the navel, making walking difficult. To avoid military service, he hired a substitute and visited Dai Ren. Dai Ren also diagnosed cold-dampness. He explained: Cold obstructs Yang fire, causing pain; dampness causes stagnation in the meridians, causing swelling. First, he induced emesis with bitter agents. Then, he administered over one hundred pills of Zhouche Wan and three to four qian of Xunchuan San, resulting in slight purgation of one or two movements. Dai Ren remarked: "If strong purgatives cannot attack the pathogen, how much less can hot tonics?" He then administered 120 pills of Shenxiong Wan and three to four qian of Tongjing San, yielding only four bowel movements. The next day, 80 pills of Shenxiong Wan were given, resulting in one or two additional movements. On the third day, he took four qian of Yishen San and over one hundred pills of Zhouche Wan, resulting in approximately seven or eight evacuations.
Officer Bai felt his cold knees and scrotum warming up, hardness softening, and heaviness lightening. The swelling subsided, and his appetite improved. Another round of emesis cured him completely. Before parting, Dai Ren gifted him Shufeng Wan (Shufeng Pill) and provided the prescription. This gentleman was treatable because he refused to recklessly take acrid-hot tonifying herbs.
