郭敬之，病留饮四日，浮肿不能食，脚肿连肾囊痛。先以苦剂涌之，后以舟车丸
、浚川散泻之，病去如拾遗。
又棠溪张凤村，一田叟姓杨，其病呕酸水十余年。本留饮，诸
医皆以燥剂燥之，中脘脐 ，以火艾燔针刺之，疮未尝
合。戴人以苦剂越之，其涎如胶，乃出二、三升，谈笑而愈。
蔡寨成家一童子，年十五岁，病疸一年，面黄如金，遍身浮肿乏力，惟食盐与焦
物。戴人以茶调散吐之，涌涎一盂；临晚，又以舟车丸七、八十粒，通经散三钱，下四、五
行；待六、七日，又以舟车丸、浚川散，下四、五行。盐与焦物见而恶之，面色变红。后再
以茶调散涌之，出痰二升，方能愈矣。
又一男子作赘，偶病疸，善食而瘦，四肢不举，面黄无力。其妇翁欲弃之，其女子不肯，曰∶
我已生二子矣，更适他乎？妇翁本农者，召婿，意欲作劳，见其病甚，每日辱诟。人教之饵
胆矾丸、三棱丸，了不关涉，针灸祈禳，百无一济。戴人见之，不诊而疗，使服涌剂，去积痰
宿水一斗；又以泄水丸、通经散，下四、五十行不止。戴人命以冰水一盂，饮之立止。次服平胃
散等，间服槟榔丸五、七日，黄退力生。盖脾疸之证，湿热与宿谷相搏故也。俗谓之金劳黄。
又朱葛周黄刘三家，各有仆，病黄胆，戴人曰∶仆役之职，饮食寒热，风暑湿寒，寻常触冒
也，恐难调摄，虚费治功。其二家留仆于戴人所，从其饮饵。其一仆，不离主人执役。三
人同服苦散以涌之，又服三花神 丸下之，五日之间，果二仆愈而一仆不愈，如其言。
律科王敏之，患水疝（一种以阴囊肿大、积水为主要表现的疾病），其病机在于寒邪侵袭形体之中。
郭敬之，患留饮（水饮停聚体内不去）四天，身体浮肿无法进食，脚部肿胀并牵连肾囊疼痛。先用苦味催吐剂涌吐痰涎，后用舟车丸、浚川散泻下逐水，病去如探囊取物般容易。
又棠溪张凤村有一位姓杨的老农，呕吐酸水十多年。这本是留饮证，各位医生都用燥湿药治疗，并在中脘穴和脐部用艾火灸刺，疮口从未愈合。戴人（张从正号）用苦味催吐剂使痰涎涌出，其痰涎像胶一样粘稠，共吐出二三升，谈笑间病愈。
蔡寨成家有一个十五岁的童子，患黄疸一年，面色黄如金子，全身浮肿乏力，只喜欢吃咸食和焦糊食物。戴人用茶调散让他催吐，涌出一盂痰涎；傍晚时，又用舟车丸七八十粒、通经散三钱，泻下四五次；等到六七天之后，再用舟车丸、浚川散，继续泻下四五次。见到咸食和焦物便厌恶，面色转红。之后再以茶调散催吐，吐出痰涎二升，病才能痊愈。
又有一男子入赘，偶然患黄疸，食欲好但消瘦，四肢无力抬举，面色发黄无神。他的岳父想抛弃他，女儿不肯，说：“我已经生了两个孩子，难道还要改嫁吗？”岳父本是农民，叫女婿干活，见病情严重，每天辱骂他。有人教他服用胆矾丸、三棱丸，完全无效，针灸祈祷也毫无效果。戴人见到他，不诊脉直接治疗，让他服用催吐剂，排出积痰宿水一斗；又用泄水丸、通经散，泻下四五十次不止。戴人命令他用一盆冰水喝下，腹泻立刻停止。随后服用平胃散等药，间断服用槟榔丸五到七天，黄色消退，体力恢复。这是因为脾疸的证候，是湿热与未消化的谷物相互搏结所致。俗称金劳黄。
又朱葛周黄刘五家，各有仆人患黄疸。戴人说：“仆役的职责，饮食冷热无常，风暑湿寒经常触犯，恐怕难以调养护理，白白浪费治疗功夫。”其中两家把仆人留在戴人处，听从他的饮食调理。另一仆人，不离主人身边服役。三人同服苦散催吐，又服三花神丸泻下，五天之间，果然两个仆人痊愈而一个没痊愈，正如他所言。
Wang Minzhi, a physician of the Law Department, suffered from Shui Han (Water Hernia, a disease characterized by scrotal swelling and fluid accumulation). The pathogenesis lay in cold pathogens invading the interior of the body.
Guo Jingzhi suffered from Liu Yin (Retention of Fluids, retention of pathological fluids within the body) for four days. He presented with edema, inability to eat, and swelling of the feet extending to the scrotum with pain. Initially, he was treated with a bitter emetic to induce vomiting (Yong Fa), followed by treatment with Zhou Che Wan (Boat Cart Pill) and Jun Chuan San (River Clearing Powder) to purge water. The disease was eliminated as easily as picking up a lost item.
Additionally, an old farmer surnamed Yang from Zhang Fengcun, Tangxi, had been vomiting sour fluid for over ten years. This was originally a case of Liu Yin. Various physicians treated him with drying agents, applying moxibustion and acupuncture at Zhongwan (CV12) and the umbilicus, yet the sores never healed. Dai Ren (Zhang Congzheng's courtesy name) used a bitter emetic to induce vomiting. His phlegm came out like glue, totaling two to three sheng (a unit of volume). He recovered while chatting and laughing.
A fifteen-year-old boy from Chengjia Village, Caizhai, suffered from Dan Huang (Jaundice) for one year. His face was yellow like gold, his whole body was swollen and weak, and he only desired salty foods and charred items. Dai Ren administered Cha Tiao San (Tea Regulation Powder) to induce vomiting, expelling a bowlful of phlegm. In the evening, he administered seventy to eighty pills of Zhou Che Wan and three qian of Tong Jing San (Meridian Unblocking Powder), resulting in four or five bowel movements. After six or seven days, he again used Zhou Che Wan and Jun Chuan San, causing another four or five bowel movements. Upon seeing salty and charred foods, he felt disgust, and his complexion turned red. Subsequently, Dai Ren induced vomiting again with Cha Tiao San, expelling two sheng of phlegm, after which the patient recovered.
Another man, who had entered his wife's family as a live-in son-in-law, accidentally contracted Dan Huang. He had a good appetite but became emaciated, his limbs were unable to move, and his face was yellow and devoid of strength. His father-in-law wished to discard him, but his daughter refused, saying, "I have already borne two children; shall I remarry?" The father-in-law was originally a farmer and called his son-in-law to perform labor. Seeing the severity of the illness, he insulted him daily. Someone advised him to take Dan Fan Wan (Alum Pill) and San Leng Wan (Burreed Rhizome Pill), but these had no effect. Acupuncture, prayer, and exorcism also failed. Dai Ren saw him and treated him without taking the pulse. He prescribed an emetic, which expelled one dou (a unit of volume) of accumulated phlegm and retained water. He then used Xie Shui Wan (Water Purging Pill) and Tong Jing San, resulting in more than forty or fifty bowel movements. Dai Ren ordered him to drink a bowlful of ice water, which immediately stopped the diarrhea. Subsequently, he took Ping Wei San (Regulate the Stomach Powder) and intermittently took Bing Lang Wan (Areca Seed Pill) for five to seven days. The jaundice subsided, and strength returned. This is because the syndrome of Pi Dan (Spleen Jaundice) results from damp-heat clashing with undigested food. It is commonly known as Jin Lao Huang (Metal Exhaustion Jaundice).
Furthermore, the families of Zhu, Ge, Zhou, Huang, and Liu each had servants suffering from Dan Huang. Dai Ren said, "The duties of servants involve irregular diet temperature and frequent exposure to wind, summer heat, dampness, and cold. It is difficult to regulate their lifestyle, and it would be a waste of therapeutic effort." Two of the families kept their servants at Dai Ren's residence, following his dietary instructions. One servant remained with his master to perform duties. All three took Ku San (Bitter Powder) to induce vomiting and San Hua Shen Wan (Three Flowers Divine Pill) to purge. Within five days, indeed, two servants recovered while one did not, exactly as Dai Ren predicted.
