一妇年三十四岁，经水不行，寒热往来，面色痿黄，唇焦颊赤，时咳三、两声。
向者所服之药，黑神散、乌金丸、四物汤、烧肝散、鳖甲散、建中汤、宁肺散，针艾百千，病转剧。家人
意倦，不欲求治。戴人悯之，先涌痰五、六升。午前涌毕，午后食进，余证悉除。后三日，复
轻涌之，又去痰一、二升，食益进。不数日，又下通经散，泻讫一、二升。后数日，去死皮
数重，小者如肤片，大者如苇膜。不一月，经水行，神气大康矣。
一妇身冷脉微，食沸热粥饭，六月重衣，以狐帽蒙其首犹觉寒，泄注不止。常
服姜、附、硫黄燥热之剂，仅得平和，稍用寒凉，其病转增，三年不愈。戴人诊其两手脉，皆如
绳有力，一息六、七至。《脉诀》曰∶六数七极热生多。以
凉布搭心，次以新汲水淋其病处，妇乃叫杀人。不由病者，令人持之，复以冷水淋其三、四
十桶，大战汗出，昏困一、二日，而向之所恶皆除。此法华元化已曾用，世无知者。
常仲明之妻，每遇冬寒，两手热痛。戴人曰∶四肢者，诸阳之本也，当夏时散
越而不痛，及乎秋冬，收敛则痛。以三花神 丸大下之，热遂去。
柏亭王论夫，本因丧子忧抑，不思饮食。医者不察，以为胃冷，血燥之剂尽用
之。病变呕逆而瘦，求治于戴人。一视涌泄而愈。愈后忘其禁忌，病复作，大小便俱秘，脐
腹撮痛，呕吐不食一日，大小便不通十有三日，复问戴人。戴人曰∶令先食葵羹、菠菱菜、
血，以润燥开结；次与导饮丸二百余粒，大下结粪；又令恣意饮冰水数升，继搜风丸桂苓白
术散以调之；食后服导饮丸三十余粒。不数日，前后皆通，药止呕定食进。此人临别，又留
润肠丸，以防复结；又留涤肠散，大闭则用之。凡服大黄、牵牛，四十余日方瘳。论夫自叹
曰∶向使又服向日热药，已非今日人矣。一僧问戴人。云∶肠者，畅也。不畅何以？此一句
一位三十四岁的妇女，月经停止不来，寒热交替发作，面色萎黄无华，嘴唇焦枯，脸颊发红，偶尔咳嗽两三声。
此前她服用的药物有黑神散、乌金丸、四物汤（补血调经方剂）、烧肝散、鳖甲散、建中汤（温中补虚方剂）、宁肺散，并施针艾灸数百次，病情反而加重。家人感到厌倦，不想再求医治疗。张从正（字戴人）怜悯她，先用涌吐法排出痰涎五到六升。中午前涌吐完毕，下午就能进食，其余症状全部消除。三天后，再次进行轻度涌吐，又排出痰涎一到二升，食欲进一步增加。没过几天，又服用通经散，泻下了一到二升秽物。过了数日，脱去几层死皮，小的像皮肤碎片，大的像芦苇薄膜。不到一个月，月经来潮，精神元气大大恢复健康。
另一位妇女身体冰冷，脉搏微弱，只能吃滚烫的粥饭，六月天穿着厚重的衣服，用狐狸皮帽子蒙住头部仍然觉得寒冷，腹泻不止。她长期服用干姜、附子、硫黄等燥热性质的药物，仅能维持平和状态，稍微使用寒凉药物，病情就会加重，三年未能痊愈。张从正诊察她的两手脉象，都如绳索般有力，一呼一吸间跳动六七次。《脉诀》说：“六数七极，热生多。”他用凉布搭在心口，接着用新汲取的冷水淋洒患处，妇人痛得大叫杀人。不由病人自主，让人按住她，再用冷水淋洒三四十桶，大汗淋漓地剧烈战栗出汗，昏沉困倦一两天，之前所厌恶的症状全部消除。这种方法华佗（字元化）已经曾用过，世上无人知晓。
常仲明的妻子，每逢冬季寒冷，双手发热疼痛。张从正说：“四肢是诸阳经的根本，在夏季时阳气发散所以不痛，到了秋冬季节，阳气收敛反而疼痛。”用三花神丸大幅泻下，热症随即去除。
柏亭王论夫的夫人，原本因为丧子之痛忧郁压抑，不思饮食。医生没有仔细考察，认为是胃冷、血燥，用尽了养血润燥的药物。病变为呕吐逆气且消瘦，向张从正求治。一眼看出通过涌吐和泻下即可治愈。病愈后忘记了禁忌，疾病复发，大小便都闭塞不通，脐腹部拘急疼痛，呕吐不食一天，大小便不通十三天，再次询问张从正。张从正说：“让你先吃葵菜羹、菠菜、猪血，以滋润干燥、开通结滞；接着给予导饮丸二百多粒，大幅泻下积结的大便；又让你肆意喝几升冰水，随后用搜风丸、桂苓白术散（健脾利湿方剂）来调理；饭后服用导饮丸三十多粒。没过几天，前后二便都通畅了，药止住了呕吐，定下了食欲，开始进食。这个人临别时，又留下了润肠丸，以防再次结滞；又留下了涤肠散，大便秘结时使用。凡是服用大黄、牵牛子，四十多天才能痊愈。王论夫自己感叹道：‘假如当时又服用了以前的热性药物，就已经不是今天的人了。’一位僧人问张从正。说：‘肠者，畅也。’不畅为什么呢？这一句话……”
A woman, aged thirty-four, had amenorrhea (absence of menstruation), alternating chills and fever (alternating cold and heat sensations), sallow complexion with lack of luster, dry cracked lips, red cheeks, and occasional coughing two or three times.
Previously, she had taken medications including Heishen San (Black Divine Powder), Wujin Wan (Black Gold Pill), Siwu Tang (Four Substances Decoction [a blood-nourishing formula]), Shaogan San, Biejia San, Jianzhong Tang (Middle-Jiao Building Decoction [a warming and tonifying formula]), and Ningfei San, and underwent hundreds of acupuncture and moxibustion sessions, yet her condition worsened. Her family grew weary and lost the desire to seek further treatment. Zhang Congzheng (courtesy name Dairen) pitied her and first induced vomiting to expel five to six sheng of phlegm. By noon, after the emesis was completed, she could eat by afternoon, and all other symptoms disappeared. Three days later, a mild emetic therapy was repeated, expelling another one to two sheng of phlegm, and her appetite improved further. Within a few days, she took Tongjing San (Menstruation-Promoting Powder), resulting in the purgation of one to two sheng of foul matter. After several days, several layers of dead skin peeled off; small pieces resembled skin flakes, while large ones resembled reed membranes. Within less than a month, her menstruation resumed, and her spirit and vital energy recovered significantly.
Another woman presented with a cold body and a faint pulse. She could only consume boiling hot porridge and rice, wore heavy clothing in June, and still felt cold even with a fox-skin hat covering her head. She suffered from incessant diarrhea. She had long taken drying and heating agents such as Shengjiang (Dried Ginger Rhizome), Fuzi (Prepared Aconite Root), and Liuhuang (Sulfur), achieving only a stable state; any slight use of cooling herbs exacerbated her illness, which persisted for three years without cure. Zhang Congzheng palpated both wrists and found the pulses firm like ropes, beating six or seven times per breath cycle. The *Maijue* states: "Six is rapid, seven is extreme, indicating excessive heat." He placed a cool cloth on her heart area, then splashed fresh well water onto the affected areas. The woman screamed in pain. Restraint was necessary as she was not in control; forty buckets of cold water were poured over her. She experienced profuse sweating accompanied by severe shivering, followed by drowsiness and fatigue for one or two days, after which all previously disliked symptoms vanished. This method had been used by Hua Tuo (courtesy name Yuanhua), but it was unknown to the world.
The wife of Chang Zhongming suffered from heat and pain in both hands whenever winter cold arrived. Zhang Congzheng said, "The four limbs are the root of all Yang meridians. In summer, when Yang Qi disperses outward, there is no pain; but in autumn and winter, when Yang Qi converges inward, pain occurs." He administered Sanhua Shenwan (Three-Flower Divine Pill) for strong purgation, and the heat syndrome subsequently resolved.
The wife of Wang Lunfu from Baiting originally suffered from loss of appetite due to grief and depression following the death of her son. Physicians failed to investigate properly, diagnosing stomach cold and blood dryness, and employed various blood-nourishing and moistening agents indiscriminately. Her condition deteriorated into vomiting, regurgitation, and emaciation, leading her to seek treatment from Zhang Congzheng. A single observation indicated that emesis and purgation would cure her. After recovery, forgetting dietary restrictions, her illness relapsed with constipation of both stool and urine, cramping abdominal pain, vomiting and refusal to eat for one day, and total obstruction of bowel and bladder movements for thirteen days. She consulted Zhang Congzheng again. Zhang Congzheng instructed: "First, consume okra soup, spinach, and pig blood to moisten dryness and resolve stagnation; next, take over two hundred pills of Dao Yin Wan (Guide Drink Pill) to vigorously purge accumulated feces; then, drink several sheng of ice water freely, followed by regulation using Sofeng Wan (Wind-Searching Pill) and Guiling Baizhu San (Cinnamon Twig, Poria, and Atractylodes Macrocephala Powder); finally, take more than thirty pills of Dao Yin Wan after meals. Within a few days, both anterior and posterior passages became unobstructed, vomiting ceased, appetite returned, and food intake resumed. Upon departure, he left behind Runchang Wan (Intestine-Moistening Pill) to prevent recurrence, and Dichang San (Intestine-Cleansing Powder) for severe constipation. It took more than forty days of consuming Dahuang (Rhubarb Rhizome and Stem) and Qianniu (Pharbitis Seed) for full convalescence. Wang Lunfu sighed, 'Had I continued taking those previous heating medicines, I would no longer be alive today.' A monk asked Zhang Congzheng, saying, 'The intestine (Chang) implies smooth flow (Chang). If it is not smooth, why?'"
