棠溪李民范，初病嗽血。戴人以调胃汤一两，加当归使服之，不动。再以舟车丸
五、六十粒，过三、四行，又呕血一碗。若庸工则必疑。不再宿，又与舟车丸百余粒，通经散三、
四钱，大下之，过十余行，已愈过半。仍以黄连解毒汤，加当归煎服之，次以草茎鼻中出血
半升。临晚，又用益肾散，利数行乃愈。
高烁巡检之子八岁，病热。医者皆为伤冷治之，以热药攻矣。欲饮水，水禁而不
与。内水涸竭，烦躁转生，前后皆闭，口鼻俱干，寒热往来，嗽咳时作，遍身无汗。又欲灸
。适遇戴人。戴人责其母曰∶重 浓被，暖炕红炉，儿
已不胜其热矣，尚可灸乎？其母谢以不明。戴人令先服人参柴胡饮子，连进数服，下烂鱼肠
之类，臭气异常。渴欲饮水，听其所欲，冰雪凉水，连进数杯。节次又下三、四十行，大热
方去。又与牛黄通膈丸，复下十余行，儿方大痊。前后约五十余行，略无所困，冰雪水饮至一斛。向灸之，当何如哉？
武阳仇天祥之子，病发寒热。诸医作骨蒸劳治之，半年病愈甚。以礼来聘戴人。
戴人往视之。诊其两手脉，尺寸皆潮于关，关脉独大。戴人曰∶痈象也。问其乳媪∶
曾有痛处否？乳媪曰∶无。戴人令儿去衣，举其两手，观其两胁下，右胁稍高。戴人
以手侧按之，儿移身乃避之，按其左胁则不避。戴人曰∶此肺部有痈也，非肺痈也。若肺
痈已吐脓矣。此不可动，止可以药托其里，以待自破。家人皆疑之，不以为然。服药三日
，右胁有三点赤色。戴人连辞云∶此儿之病，若早治者，谈笑可已，今已失之迟。然破之
后，方验其生死矣。若脓破黄赤白者生也，脓青黑者死也。遂辞而去，私告天祥之友李简之曰
必有一证也。其证乃死矣，肺死于巳。至期而头眩不举，不数日而死也。其父曰∶群医治之
，断为骨蒸证。戴人独言其肺有痈也。心终疑之。及其死，家人辈以火焚其棺。既燃，天
祥以杖破其胁下，果出青黑脓一碗。天祥仰天哭曰∶诸医误杀吾儿矣！
棠溪的李民范，起初患病咳嗽并咳血。张从正（字戴人）用调胃汤一两，加入当归让患者服用，但症状未缓解。随后又给予舟车丸五、六十粒，排便三、四次后，再次呕吐出一碗血。如果是庸医，必定会产生疑虑。但不等过一夜，又给予舟车丸一百多粒，以及通经散三、四钱，进行强力泻下，排便十多次后，病情已好转过半。接着仍用黄连解毒汤，加入当归煎服，随后用草茎刺激鼻腔出血半升。傍晚时，又使用益肾散，利下数次后才痊愈。
高烁巡检的儿子八岁，患发热病。医生们都当作伤冷来治疗，使用热性药物攻伐。孩子想喝水，却被禁止不给。导致体内津液枯竭，烦躁产生，大小便均闭塞，口鼻干燥，寒热往来，咳嗽不时发作，全身无汗。又想施灸。恰好遇到张从正。张从正责备孩子的母亲说：“裹着厚重的被子，炕上温暖如红炉，孩子已经承受不住这种热了，还可以施灸吗？”母亲道歉说自己不懂医术。张从正令先服用人参柴胡饮子，连续服用几剂后，排出像烂鱼肠一样的东西，气味异常臭秽。孩子口渴想喝水，听任其意愿，冰雪凉水，连续喝了几杯。分次又排便三、四十次，大热才退去。接着又给予牛黄通膈丸，又排便十多次，孩子才完全康复。前后约排便五十多次，身体略微没有困倦感，喝了冰雪水多达一斛。如果之前施灸，会怎么样呢？
武阳的仇天祥之子，发病出现寒热症状。众医生将其作为骨蒸劳证治疗，半年后病情加重。以礼聘请张从正。张从前往诊治。诊察他的两手脉象，寸关尺三部中，尺寸部脉象相对于关部显得微弱（潮于关），唯独关脉盛大。张从正说：“这是痈肿的脉象。”询问乳母：“孩子以前有疼痛的地方吗？”乳母说：“没有。”张从正令孩子脱去衣服，举起双手，观察两胁下，右胁稍高。张从正用手侧面按压，孩子移动身体躲避，按压左胁则不躲避。张从正说：“这是肺部有痈，但不是肺痈。如果已经是肺痈，应该已经吐出脓液了。这种情况不可妄动，只可以用药物托里，等待它自行破溃。”家人们都怀疑，不以为然。服药三天后，右胁出现三个红点。张从正连连叹息说：“这个孩子的病，如果早治，谈笑间即可痊愈，现在已经延误太迟了。然而破溃之后，才能验证生死。如果脓液呈黄赤白色者生，青黑色者死。”于是辞别离去，私下告诉仇天祥的朋友李简之说：“必然有一个征兆，那就是死亡。肺死于巳时（上午9-11点）。到了期限果然头晕目眩无法抬头，没过几天就死了。父亲说：‘众医生治疗，断定为骨蒸证。只有戴人说肺有痈。心里始终怀疑。’等到孩子死后，家人用火焚烧棺材。火点燃后，仇天祥用杖击破胁下，果然流出一碗青黑色的脓。仇天祥仰天痛哭说：‘众医生误杀了我的儿子啊！’”
Li Minfan of Tangxi initially suffered from coughing and hemoptysis. Zhang Congzheng (courtesy name Dairen) prescribed one liang of Tiaowei Decoction (Regulate the Stomach Decoction) with added Danggui (Angelica sinensis), which failed to alleviate symptoms. Subsequently, 50–60 pills of Zhouche Wan (Boat Cart Pill) were administered; after three or four bowel movements, he vomited a bowl of blood. A mediocre physician would likely have harbored doubts. Without waiting for another night, over 100 pills of Zhouche Wan and 3–4 qian of Tongjing San (Unblock Meridians Powder) were given to induce strong purgation. After more than ten bowel movements, the condition had improved by more than half. Thereafter, Huanglian Jiedu Tang (Coptis Decoction to Relieve Toxicity) with added Danggui was decocted and taken orally. Next, a grass stem was used to induce nasal bleeding of half a sheng. In the evening, Yishen San (Tonify Kidney Powder) was applied, and after several episodes of diuresis/purgation, he recovered.
The eight-year-old son of Gao Shuo, an inspection officer, suffered from fever. Physicians treated it as cold injury, using hot-natured drugs to attack the pathogen. When the child desired water, it was forbidden and not provided. Consequently, internal fluids dried up, irritability arose, both urination and defecation were blocked, mouth and nose were dry, chills and fever alternated, coughs occurred intermittently, and there was no sweat on the entire body. Moxibustion was also planned. Fortunately, Zhang Congzheng encountered them. Zhang reprimanded the mother, saying, "Wrapped in heavy quilts, with a warm kang and red stove, the child can already no longer bear the heat; how can moxibustion be considered?" The mother apologized for her ignorance. Zhang ordered the administration of Renshen Chaihu Yinzi (Ginseng and Bupleurum Drink). After several doses, foul-smelling discharge resembling rotten fish intestines was passed. Thirsty and desiring water, the child was allowed to drink freely, consuming cups of ice-cold water repeatedly. Through successive stages, thirty to forty bowel movements occurred, and only then did the high fever subside. Niuhuang Tongge Wan (Calculus Bovis Clearing the Diaphragm Pill) was then given, resulting in another ten-plus bowel movements, after which the child fully recovered. In total, about fifty bowel movements occurred, leaving the child slightly fatigued but otherwise untroubled, having consumed up to one hu of ice water. What would have happened if moxibustion had been performed?
The son of Qiu Tianxiang of Wuyang developed chills and fever. Various physicians treated him as bone-steaming consumption (Gu Zheng Lao), causing the illness to worsen over half a year. He was invited with courtesy to see Zhang Congzheng. Upon examination, Zhang palpated the pulses at both wrists: the Cun and Chi positions appeared weak relative to the Guan position, while the Guan pulse alone was large. Zhang stated, "This is the pulse image of an abscess." He asked the wet nurse, "Did the child previously have any painful areas?" The nurse replied, "No." Zhang instructed the child to remove his clothes and raise both hands to observe the hypochondriac regions; the right side was slightly higher. Pressing laterally with his hand, Zhang noted that the child shifted away when the right hypochondrium was pressed but did not avoid pressure on the left. Zhang said, "There is an abscess in the lung region, but it is not Lung Abscess (Fei Yong). If it were Lung Abscess, pus would already have been expectorated. This condition should not be disturbed aggressively; rather, herbs should be used to support the interior, awaiting spontaneous rupture." The family doubted this assessment. After three days of medication, three red spots appeared on the right hypochondrium. Zhang sighed repeatedly, saying, "If this child's illness had been treated early, it could have been cured with ease; now it is too late. However, life or death will be verified only after rupture. If the pus is yellow, red, or white, the patient lives; if green or black, the patient dies." He then took his leave and privately told Li Jianzhi, a friend of Tianxiang, "There must be a sign; the child will die. The Lung Qi fails at Si hour (9–11 AM)." At the appointed time, the child suffered dizziness and could not lift his head, dying a few days later. The father said, "The group of physicians diagnosed bone-steaming syndrome. Only Dairen claimed there was a lung abscess. I remained skeptical." After death, the family burned the coffin. Once ignited, Tianxiang struck the hypochondrium with a staff, and indeed, a bowl of green-black pus flowed out. Tianxiang cried to heaven, "The physicians mistakenly killed my son!"
