有宋子玉者，俄省曰∶彼已热死，我其改之？敬邀戴人。戴人曰∶公之疾，服热药久矣。先
去其药邪，然后及病邪，可下三百行。子玉曰∶敬从教。先以舟车丸、浚川散，大下一盆许。
明日减三分，两足旧不仁，是日觉痛痒。累至三百行始安。戴人曰∶诸痿独取阳明。阳明
者，胃与大肠也。此言不止谓针也，针与药同也。
一男子，病口疮数年，上至口，中至咽嗌，下至胃脘，皆痛，不敢食热物。一涌
一泄一汗，十去其九；次服黄连解毒汤，不十余日皆释。
西华束茂之，病虚劳寝汗，面有青黄色，自膝以下，冷痛无汗，腹中燥热。医以
姜、附补之，五晦朔不令饮水，又禁梳头，作寒治之。请于戴人。戴人曰∶子之病，不难
愈，难于将护，恐愈后阴道转茂，子必不慎。束生曰∶不敢。戴人先以舟车丸、浚川散，下
五、七行。心
火下降，觉渴，与冰水饮之，又令澡浴，数日间面红而泽。后以河水煮粥，温养脾胃。河水
能利小溲。又以活血当归丸、人参柴胡散、五苓散、木香白术散调之。病大瘥，寝汗皆止，
两足日暖，食进。戴人常曰∶此本肺痹，当以凉剂。盖水之一物，在目为凉，在皮为汗，
在下为小溲。谷多水少为常，无水可乎？若禁饮水必内竭，内竭则燥热生焉。人若不渴，与水亦不肯饮之
矣。束生既愈，果忘其戒，病复作。戴人已去，乃殂。
宛丘的营军校尉中有三人，都患有痿证，多年不愈。腰部以下肿痛且无法抬起，全身皮肤出现红色疮疡，双眼视物昏暗，向戴人（张从正）求医。戴人打算使用泻下剂治疗，其中两人不听劝阻，被其他医生使用的温补药物所迷惑，最终都去世了。与他们同患此病的宋子玉，不久后醒悟道：“他们都已经因热毒而死，我难道要改变策略吗？”于是恭敬地邀请戴人诊治。戴人说：“您的病，服用热性药物已经很久了。先去除体内的药邪，然后再治疗疾病本身的邪气，可以使用泻下法三百次。”宋子玉说：“恭敬地听从教诲。”先用舟车丸、浚川散，大量泻下一盆左右。第二天症状减轻三分，双脚原本麻木无知觉，当天开始感觉痛痒。累计泻下三百次后才安定下来。戴人说：“治疗各种痿证，唯独取治阳明经。阳明经，指的是胃与大肠。这句话不仅仅指针刺，针法与药法是相通的。”
一名男子，患口疮数年，溃疡从上至口唇，中至咽喉，下至胃脘部，全都疼痛，不敢吃热的食物。经过一次涌吐、一次泻下、一次发汗，病情去除了十分之九；接着服用黄连解毒汤（Huanglian Jiedu Tang, Coptis Decoction for Resolving Toxicity），不到十天就全部痊愈。
西华的束茂之，患虚劳证并伴有夜间盗汗，面色呈现青黄色，自膝盖以下冷痛且无汗，腹部内部燥热。医生用干姜、附子进行温补，五个昼夜禁止他饮水，又禁止梳头，当作寒证来治疗。束茂之向戴人求助。戴人说：“您的病，不难治愈，难在病后的调养，恐怕痊愈后房事过度，您必定不能谨慎节制。”束生说：“我不敢。”戴人先用舟车丸、浚川散，泻下五到七次。心火下降，感到口渴，给他喝冰水，又让他洗澡，几天后面色红润有光泽。后来用河水煮粥，温和滋养脾胃。河水能通利小便。又用活血当归丸（Huoxue Danggui Wan, Blood-Invigorating Angelica Pill）、人参柴胡散（Renshen Chaihu San, Ginseng and Bupleurum Powder）、五苓散（Wuling San, Five-Ingredient Powder with Poria）、木香白术散（Muxiang Baizhu San, Aucklandia and Atractylodes Powder）来调理。病情大好转，盗汗停止，两脚每天变暖，食欲增进。戴人常说：“这本来是肺痹（Fei Bi, Lung Bi - obstruction of the lung meridian），应当用凉性药剂治疗。水这一物质，在眼中表现为泪液（清凉），在皮肤表现为汗液，在下部表现为小便。谷物多而水少是常态，没有水怎么行呢？如果禁止饮水必然导致体内津液枯竭，体内枯竭则燥热产生。人如果不觉得渴，给水也不肯喝啊。”束生痊愈后，果然忘记了戒律，病情复发。此时戴人已经离开，束生便去世了。
Three military officers in the camp of Wanchou all suffered from Wei syndrome (Flaccidity Syndrome), which had persisted for years without healing. Below the waist, they experienced swelling, pain, and inability to move; their entire bodies were covered with red sores, and their eyesight was dim. They sought treatment from Dai Ren (Zhang Congzheng). Dai Ren intended to administer purgative agents, but two of them refused, having been misled by warm-tonic medicines prescribed by other physicians; both eventually died. Among those suffering from the same condition was Song Ziyu. After a short while, he realized: "They have already died from heat toxicity; should I not change my approach?" He respectfully invited Dai Ren. Dai Ren said, "Your illness has resulted from long-term consumption of hot-natured drugs. First, eliminate the pathogenic factor introduced by the medication, then address the original disease pathogen. You may undergo purgation three hundred times." Song Ziyu replied, "I respectfully obey your teaching." Dai Ren first administered Zhouche Wan (Boat Cart Pill) and Junchuan San (River-Dredging Powder), resulting in a large volume of purgation (approximately one basin). The next day, symptoms decreased by thirty percent. His feet, previously numb and insensible, began to feel pain and itching on that day. After accumulating three hundred purgations, he finally stabilized. Dai Ren stated, "In treating various forms of Wei syndrome, one exclusively targets the Yangming channel. Yangming refers to the Stomach and Large Intestine. This principle applies not only to acupuncture but also to herbal medicine; the methods are consistent."
A man suffered from mouth ulcers for several years. The lesions extended from the lips upwards, down through the throat, and further down to the epigastrium, causing pain throughout these areas. He dared not consume hot foods. Following one session of emesis (Yong), one session of purgation (Xie), and one session of diaphoresis (Han), ninety percent of the symptoms were resolved. Subsequently, he took Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity), and within ten days, he fully recovered.
Shu Maozhi from Xihua suffered from Xu Lao (Deficiency Consumption) accompanied by night sweats. His complexion showed a bluish-yellow hue. From the knees downward, his legs were cold, painful, and devoid of sweat, while his abdomen felt internally dry and hot. Physicians treated him with Gan Jiang (Dried Ginger) and Fu Zi (Prepared Aconite Root) for warming tonification, forbade him from drinking water for five days and nights, prohibited hair combing, and diagnosed it as a cold pattern. Shu sought help from Dai Ren. Dai Ren said, "Your illness is not difficult to cure, but difficult to manage post-recovery. If you engage in excessive sexual activity after recovery, you will likely fail to exercise caution." Shu replied, "I dare not." Dai Ren first administered Zhouche Wan and Junchuan San, inducing purgation five to seven times. As Heart Fire descended, Shu felt thirsty and was given ice water to drink. He was also instructed to bathe. Within a few days, his face became ruddy and lustrous. Later, he consumed congee cooked with river water to gently nourish the Spleen and Stomach. River water facilitates urination. He was further regulated using Huoxue Danggui Wan (Blood-Invigorating Angelica Pill), Renshen Chaihu San (Ginseng and Bupleurum Powder), Wuling San (Five-Ingredient Powder with Poria), and Muxiang Baizhu San (Aucklandia and Atractylodes Powder). His condition greatly improved; night sweats ceased, his feet warmed daily, and his appetite increased. Dai Ren often remarked, "This was originally Fei Bi (Lung Obstruction), which should be treated with cooling agents. Water manifests as tears (cooling) in the eyes, as sweat on the skin, and as urine below. Normally, grain intake exceeds water intake; how can there be no water? If water intake is forbidden, internal fluids will inevitably deplete, leading to dryness and heat generation. If a person does not feel thirsty, they will refuse even if offered water." After recovering, Shu indeed forgot the warnings, and his illness relapsed. By the time Dai Ren had departed, Shu passed away.
