一小儿误吞一钱，在咽中不下。诸医皆不能取，亦不能下。乃命戴人。戴人熟思
之，忽得一策∶以净白表纸，令卷实如箸，以刀纵横乱割其端，作
之状；又别取一箸，缚针钩于其端，令不可脱，先下咽中，轻提轻抑，一探之，觉钩入于钱窍；然后以纸卷纳
之咽中，与钩尖相抵，觉钩尖入纸卷之端，不碍肌肉，提之而出。
棠溪栾彦刚，病下血。医者以药下之，默默而死。其子企，见戴人而问之曰∶吾
父之死，竟无人知是何证？戴人曰∶病锉其心也。心主行血，故被锉则血不禁，若血温身
热者死。火数七，死必七日，治不当下，若下之，不满数。企曰∶四日死，何谓病锉心？
戴人曰∶智不足而强谋，力不足而强与，心安得不锉也？栾初与邢争屋不胜，遂得此病。企由是大服，拜而学医。
霍秀才之子，年十二岁，睾丸一旁肿 。
见之曰∶此因惊恐得之。惊之为病，上行则为呕血，下则肾伤而为水肿。以琥珀通经散，一泻而消散。
上渠卜家一男子，年二十八岁，病身弱，四肢无力，面色苍黄，左胁下体侧，上
下如臂状，每发则痛无时，食不减，大便如常，小便微黄，已二、三载矣。诸医计穷，求戴
人治之。视其部分，乃足厥阴肝经，兼足少阳胆经也。张曰∶甲胆乙肝故青。其黄者，脾也。
诊胆脉小，此因惊也。惊则胆受邪，腹中当有惊涎绿水。病患曰∶昔曾屯军被火，自是而疾。
戴人夜以舟车百五十丸，浚川散四、五钱，加生姜自然汁，平旦果下绿水四、五行。或问大加
生姜何也？答曰∶辛能伐木也。下后觉微痛，令再下之，比前药减三之一，又下绿水三、四行。
痛止思食，反有力。戴人谓卜曰∶汝妻亦当病。卜曰∶太医未见吾妻，何以知之？曰∶尔感
此惊几年矣？卜省曰∶当被火时，我正在草堂中熟寐，人惊唤，我睡中惊不能言，火已塞门，
我父拽出我火中，今五年矣。张曰∶汝胆伏火惊，甲乙乘脾土，是少阳相火乘脾，脾中有热
，故能食而杀谷。热虽能化谷，其精气不完，汝必无子。盖败经反损妇人，汝妻必手足热，四肢
无力，经血不时。卜曰∶吾妻实如此，亦已五年矣。他日，门人因观《内经》，言先泻所不
胜，次泻所胜之论，其法何如，以问张。张曰∶且如胆木乘胃土，此土不胜木也。不胜之气，
寻救于子，己土能生庚金。庚为大肠，味辛者为金，故大加生姜使伐木。然先不开脾，土无由
行也。遂用舟车丸，先通其闭塞之路，是先泻其所不胜；后用姜汁调浚川散大下之，次泻
其所胜也。大抵阳干克阳干，腑克腑，脏克脏。
一个小孩误吞了一枚铜钱，卡在咽喉处下不去。各位医生都无法取出，也无法使其下行。于是请戴人（张从正）诊治。戴人仔细思考后，忽然想到一个办法：用干净的白纸卷成实心的棍状，像筷子一样粗细；用刀在纸卷的一端纵横乱割，做成类似钩子的形状；又另取一根筷子，将针钩绑在筷子上端，使其不会脱落。先将筷子探入咽喉中，轻轻提拉、按压，试探寻找，感觉到钩子进入了铜钱的孔洞；然后将纸卷塞入咽喉中，与钩尖相对抵住，感觉钩尖刺入纸卷的末端，且不损伤肌肉，向上提起便将铜钱带出。
棠溪栾彦刚，患有便血症状。医生用泻下药治疗，患者沉默不语而死。他的儿子栾企，见到戴人问道：“我父亲的死，竟然没有人知道是什么病症？”戴人说：“这是病情损伤了心脏。心主司血液运行，所以被损伤后血液无法控制，如果伴有身体发热，就会死亡。火对应的数字是七，死后必定在第七天，治疗本不该用泻法，如果用泻法，不到七天就会死。”栾企说：“父亲第四天就死了，为什么说病情损伤了心脏？”戴人说：“智慧不足却强行谋划，力量不足却强行承担，心怎么能不受到损伤呢？栾彦刚开始时与邻居争夺房屋没有获胜，于是得了这个病。”栾企因此非常佩服，拜师学习医学。
霍秀才的儿子，十二岁，一侧睾丸肿胀。戴人看后说：“这是因为惊恐导致的。惊这种病，向上发展会导致呕血，向下则损伤肾脏导致水肿。”使用琥珀通经散，一次泻下后肿胀消散。
上渠卜家的一名男子，二十八岁，身体虚弱，四肢无力，面色苍黄，左侧胁下体侧，上下呈现如手臂状的肿块，每次发作时疼痛无定时，饮食未减少，大便正常，小便微黄，已经两三年了。各位医生计策用尽，请求戴人治疗。观察其病变部位，属于足厥阴肝经，兼及足少阳胆经。张从正说：“甲胆乙肝，故颜色发青。发黄的是脾脏。”诊察胆脉细小，这是由于惊恐所致。惊恐会使胆受邪，腹中应当有因惊产生的涎水和绿水。病人说：“以前曾在军队驻扎时遭遇火灾，从此之后患病。”戴人在夜间给予舟车丸一百五十粒，浚川散四到五钱，加入生姜自然汁，清晨果然排出绿水四五行。有人问为什么大量加入生姜？回答说：“辛味能克制肝木。”泻下后感觉轻微疼痛，让再次服用泻药，比前次药量减少三分之一，又排出绿水三四行。疼痛停止，想吃东西，体力反而恢复。戴人对卜某说：“你的妻子也应当有病。”卜某说：“太医还没见过我的妻子，怎么知道？”戴人说：“你感受这种惊恐几年了？”卜某醒悟道：“当时被火烧时，我正在草堂中熟睡，被人惊醒呼喊，我在睡梦中惊恐得说不出话，火已堵塞门口，我父亲把我从火中拽出来，到现在五年了。”张从正说：“你的胆中有潜伏的火和惊恐，甲乙木气侵犯脾土，这是少阳相火侵犯脾土，脾中有热，所以能吃且消化谷物。热虽然能消化谷物，但精气不完备，你一定没有子嗣。因为败坏的经气会反损妇人，你的妻子一定手足发热，四肢无力，月经不调。”卜某说：“我的妻子确实如此，也已经五年了。”有一天，门人因为研读《内经》，提到“先泻所不胜，次泻所胜”的理论，询问这种方法如何应用，以此问张从正。张从正说：“比如胆木侵犯胃土，这是土不能胜木。不胜的气，向子行求救，己土能生庚金。庚对应大肠，味辛的属金，所以大量加入生姜以克制肝木。然而如果不先疏通脾土，土气就无法运行。”于是先用舟车丸，先打通闭塞的道路，这是先泻其所不胜；后用姜汁调服浚川散大力泻下，这是次泻其所胜。大体上，阳干克阳干，腑克腑，脏克脏。
A child accidentally swallowed a coin, which became lodged in the throat and could not pass down. All physicians were unable to retrieve it or induce its passage. Therefore, Dai Ren (Zhang Congzheng) was summoned. Dai Ren pondered deeply and suddenly devised a strategy: he took clean white paper, rolled it tightly like a chopstick, and cut the end crosswise with a knife to create a hook-like shape; additionally, he took another chopstick, bound a needle hook to its end to prevent detachment, and first inserted it into the throat, gently lifting and pressing to probe. Upon feeling the hook enter the hole of the coin, he then inserted the paper roll into the throat against the hook tip. Feeling the hook tip penetrate the end of the paper roll without injuring the mucosa, he lifted it out, retrieving the coin.
Luan Yingang from Tangxi suffered from hematochezia (blood in stool). A physician administered purgatives, after which the patient died in silence. His son, Luan Qi, saw Dai Ren and asked, "My father's death, no one knows what syndrome it was?" Dai Ren said, "The disease damaged the Heart. The Heart governs blood circulation; thus, when damaged, blood cannot be controlled. If accompanied by warm body heat, death ensues. Fire corresponds to the number seven; death must occur on the seventh day. Treatment should not involve purging. If purged, death would occur before reaching that number." Luan Qi said, "He died on the fourth day. Why do you say the disease damaged the Heart?" Dai Ren said, "Wisdom was insufficient yet forced planning occurred; strength was lacking yet forced action taken. How could the Heart not be damaged? Initially, Luan Yingang competed with Xing over a house and lost, thus contracting this illness." Luan Qi was greatly convinced and bowed to study medicine.
The son of Scholar Huo, aged twelve, had swelling in one testicle. Dai Ren observed and said, "This resulted from fright. Fright as a pathology, if ascending, leads to hematemesis (vomiting blood); if descending, it damages the Kidney leading to edema." He prescribed Hupo Tongjing San (Amber Meridian-Unblocking Powder), which resolved the swelling after a single purgative discharge.
A man from the Bu family in Shangqu, aged twenty-eight, suffered from physical weakness, powerless limbs, and a sallow complexion. On the left hypochondrium/lateral aspect, there was a mass resembling an arm in vertical extent. Pain occurred intermittently without fixed timing. Food intake remained unchanged, stools were normal, and urine was slightly yellow. This had persisted for two or three years. Physicians exhausted their strategies and sought Dai Ren's treatment. Observing the affected region, Dai Ren identified it as involving the Foot Jueyin Liver Channel and the Foot Shaoyang Gallbladder Channel. Zhang said, "Jia Gallbladder and Yi Liver correspond to green. Sallow color indicates the Spleen." Palpating the Gallbladder pulse as small, he attributed this to fright. Fright causes the Gallbladder to receive pathogenic factors, resulting in fright-induced phlegm-fluids and green water in the abdomen. The patient stated, "Previously, during military encampment, I experienced fire. Since then, I have been ill." At night, Dai Ren administered Zhouche Wan (Boat and Cart Pill) 150 pills, Junchuan San (River-Dredging Powder) 4-5 qian, mixed with fresh ginger juice. In the early morning, the patient indeed discharged four to five movements of green water. Someone asked why so much ginger was added. The answer was, "Pungent flavor can subdue Wood." After purging, mild pain was felt, so a second purge was ordered with dosage reduced by one-third compared to the previous. Another three to four movements of green water were discharged. Pain ceased, appetite returned, and strength recovered. Dai Ren told Bu, "Your wife must also be ill." Bu asked, "The Imperial Physician has not seen my wife; how do you know?" Dai Ren said, "How many years have you been afflicted by this fright?" Bu realized, "When the fire occurred, I was sleeping soundly in the thatched hall. Woken by shouts, I was too frightened to speak in my sleep. Fire blocked the door; my father pulled me from the fire. It has been five years." Zhang said, "Your Gallbladder harbors latent fire and fright. Jia-Yi Wood invades Spleen-Earth. This is Shaoyang Ministerial Fire invading Spleen-Earth. Heat in the Spleen allows consumption of food and digestion of grains. Although heat digests grain, essence and qi are incomplete; you will likely have no offspring. Defective meridians harm women. Your wife must have hot hands and feet, powerless limbs, and irregular menstruation." Bu replied, "My wife is indeed so, for five years." Later, disciples studying the *Neijing* asked about the principle of "first purge the unsuppressed, then purge the suppressed" and how to apply it. Zhang said, "For example, Gallbladder-Wood invades Stomach-Earth; Earth fails to control Wood. The failing Qi seeks rescue from its Son; Ji Earth generates Geng Metal. Geng corresponds to Large Intestine; pungent flavors belong to Metal. Thus, large amounts of ginger are used to subdue Wood. However, if Spleen-Earth is not opened first, Earth Qi cannot move." Therefore, Zhouche Wan was used first to clear blockages, representing "purging the unsuppressed"; subsequently, Junchuan San mixed with ginger juice was used for heavy purging, representing "purging the suppressed." Generally, Yang stems overcome Yang stems; Fu organs overcome Fu organs; Zang organs overcome Zang organs.
