菜寨一女，病黄，遍身浮肿，面如金色，困乏无力，不思饮饵，惟喜食生物泥煤
之属。先以苦剂蒸饼为丸，涌痰一碗；又舟车丸、通经散，下五、七行如墨汁；更以导饮丸
，磨食散气。不数日，肌肉如初。
安喜赵君玉为掾省日，病发遍身黄。往问医者。医云∶君乃阳明证。公等与麻知
几，皆受训于张戴人，是商议吃大黄者，难与论病。君玉不悦，归。自揣无别病，乃取三花神
丸八十粒，服之不动。君玉乃悟曰∶予之湿热盛矣！此药尚不动。以舟车丸、浚川散，作
剂大下一斗，粪多结者，一夕黄退。君玉由此益信戴人之言。
南乡张子明之母极肥，偶得水肿，四肢不举。戴人令上涌汗而下泄之，去水三、四
斛。初下药时，以草贮布囊，高支两足而卧。其药之行，自腰以上，水觉下行，自足以上，
水觉上行，水行之状，如蛇走隧，如线牵，四肢森然凉寒，会于脐下而出。不旬日间，病大
减，余邪未尽。戴人更欲用药，竟不能从其言。
李七老，病涌水证，面黄而喘，两足皆肿，按之陷而复起，行则濯濯有声，常欲
饮水，不能睡卧。戴人令上涌去痰而汗之，次以舟车丸、浚川散下之，以益肾散复下之，以
分阴阳利水道之剂，复下之，水尽皆瘥。
涿郡周敬之，自京师归鹿邑，道中渴，饮水过多，渐成肿满。或用三花神 丸，
惮其太峻；或用五苓散，分利水道，又太缓。淹延数旬，终无一效。盖粗工之技，止于此耳
！后手足与肾皆肿，大小便皆秘涩。常仲明求治于戴人。戴人令仲明付药，比及至，已殁矣
。戴人曰∶病水之人，其势如长川泛溢，欲以杯勺取之，难矣！必以神禹决水之法，斯愈矣！
菜寨有一位女子，患黄疸病，全身浮肿，面色如金色，疲倦乏力，不想饮食，只喜欢吃生泥炭之类的东西。先用苦味催吐药制成蒸饼丸，涌吐出一碗痰涎；接着用舟车丸、通经散，泻下五到七次，排出物像墨汁一样黑；再用导饮丸，配合磨食散行气。没过几天，肌肉恢复如初。
安喜人赵君玉在尚书省做属官时，发病全身发黄。去请教医生。医生说：“您是阳明证。”您和麻知几，都受教于张戴人（张从正），都是商量着要吃大黄的人，很难与您讨论病情。赵君玉不高兴，回家。自己揣测没有其他病，于是取三花神丸八十粒服用，药效没有反应。赵君玉醒悟道：“我的湿热太盛了！这种药还动不了它。”改用舟车丸、浚川散，一次性大量服用，泻下一斗多，粪便中结块多的，一夜之间黄色消退。赵君玉因此更加相信张戴人的言论。
南乡张子明的母亲非常肥胖，偶然得了水肿，四肢不能抬起。张戴人让她先涌吐发汗，再泻下排水，排出了三四斛水。刚开始下药时，用草填充布袋，垫高双脚仰卧。药力运行后，感觉水液从腰部以上向下流，从脚部向上流，水流运行的状态，像蛇在隧道里爬行，像线被牵引，四肢感到森然凉寒，最终汇聚于脐下排出。不到十天，病情大减，但余邪未尽。张戴人还想继续用药，患者最终没能听从他的建议。
李七老，患涌水证，面色黄且气喘，两脚都肿，按压凹陷后迅速弹起，行走时腹部有水声，经常想喝水，无法躺卧睡眠。张戴人让他先涌吐去痰并使其出汗，接着用舟车丸、浚川散泻下，再用益肾散泻下，然后用分阴阳、利水道的药剂再次泻下，水排尽后病愈。
涿郡周敬之，从京城回到鹿邑，途中口渴，饮水过多，逐渐形成肿胀满闷。有人用三花神丸，他害怕药性太猛烈；有人用五苓散，分利水道，又觉得药性太缓慢。拖延了几十天，始终没有效果。这大概是庸医的技术，只能到此为止了！后来手足和肾脏都肿，大小便都闭塞不通。常仲明向张戴人求治。张戴人让常仲明送药，等到药送到时，周敬之已经去世了。张戴人说：“患水肿病的人，病势就像长河泛滥，想用杯勺舀干它，太难了！必须用大禹治水决堤的方法，才能痊愈！”
A woman from Caizhai suffered from jaundice (Huang Bing), with generalized edema, a golden-yellow complexion, fatigue and weakness, loss of appetite, and a craving for raw mud or coal. Initially, a bitter emetic was formed into pills using steamed bread to induce vomiting, expelling one bowl of phlegm; subsequently, Zhouche Wan (Zhouche Pill) and Tongjing San (Tongjing Powder) were administered, resulting in five to seven bowel movements resembling ink; further treatment involved Daoyin Wan (Daoyin Pill) and Moshisan (Moshi Powder) to move qi and resolve stagnation. Within a few days, her muscles returned to normal.
Zhao Junyu from Anxi, while serving as a clerk in the Department of State Affairs, developed generalized yellowing of the skin. He consulted a physician who stated, "You have Yangming syndrome." The physician noted that Zhao and Ma Zhiji were both disciples of Zhang Dairen (Zhang Congzheng) and typically agreed on using Rhubarb (Dahuang), making it difficult to discuss his condition. Displeased, Zhao returned home. Suspecting no other illness, he took eighty pills of Sanhua Shenwan (Sanhua Divine Pill), but there was no effect. Realizing his damp-heat was excessive, he switched to Zhouche Wan (Zhouche Pill) and Junchuan San (Junchuan Powder), taking a large dose at once, which resulted in more than one dou of stool being expelled. Those with hardened feces cleared overnight, and the yellowing subsided. From this, Zhao further trusted Zhang Dairen's words.
The mother of Zhang Ziming from Nanxiang was extremely obese and accidentally developed edema, rendering her limbs immobile. Zhang Dairen instructed her to undergo upper-body emesis and sweating, followed by purgation to drain water, removing three or four hu of fluid. When the medication first acted, she lay supine with her feet elevated on a cloth bag stuffed with grass. As the medicine worked, she felt water flowing downward from above the waist and upward from the feet. The movement of water resembled a snake crawling through a tunnel or being pulled by a thread; her limbs felt intensely cold until the fluid converged below the navel and exited. Within ten days, the illness significantly improved, though residual pathogens remained. Zhang Dairen wished to continue treatment, but she ultimately did not follow his advice.
Li Qilao suffered from Yongshui syndrome (Gushing Water Syndrome), characterized by a sallow complexion, wheezing, bilateral foot edema where depression rebounded quickly upon pressure, audible splashing sounds when walking, frequent thirst, and inability to lie down and sleep. Zhang Dairen ordered him to first induce emesis to remove phlegm and induce sweating, then purge using Zhouche Wan (Zhouche Pill) and Junchuan San (Junchuan Powder), followed by Yishen San (Yishen Powder) for further purgation, and finally administer agents that separate yin and yang and promote urination to purge again. Once all water was eliminated, he recovered.
Zhou Jingzhi from Zhuojun returned from the capital to Luyi and became thirsty during the journey, drinking excessive amounts of water, which gradually led to swelling and fullness. Some prescribed Sanhua Shenwan (Sanhua Divine Pill), but he feared its potency was too harsh; others used Wuling San (Wuling Powder) to promote diuresis, but he found it too slow. After weeks of delay with no effect, it became evident that the skills of mediocre physicians were limited. Later, his hands, feet, and kidneys swelled, and both urination and defecation became obstructed. Chang Zhongming sought treatment from Zhang Dairen. Zhang Dairen instructed Chang to deliver the prescription, but by the time it arrived, Zhou had already died. Zhang Dairen remarked, "For patients with water retention, the pathogenic force is like a overflowing river; trying to remove it with cups and spoons is difficult! One must use the method of Yu the Great to divert the waters to achieve a cure!"
