小郑年十五，田中中暑，头痛，困卧不起。戴人以双解散汗之，又以米醋汤投之
，未解。薄晚，又以三花神 丸大下之，遂愈。

张叟年七十一，暑月田中，因饥困伤暑，食饮不进，时时呕吐，口中常流痰水，腹胁作痛。
医者概用平胃散、理中丸、导气丸，不效；又加针灸，皆云胃冷，乃问戴人。戴人曰∶痰
属胃，胃热不收，故流痰水。以公年高，不敢上涌，乃使箸探之，不药而吐之痰涎一升；
次用黄连清心散、导饮丸、玉露散以调之。饮食加进，惟大便秘，以生姜、大枣煎调胃承气
汤一两夺之，遂愈。
故息城一男子病疟，求治于戴人。诊两手脉，皆沉伏而有力，内有积也，此是肥
气。病者曰∶左胁下有肥气，肠中作痛，积亦痛，形如覆杯，间发止，今已三年，祈禳避匿
，无所不至，终不能疗。戴人曰∶此 疟也。以三花
神丸五、七十丸，以冷水送过五、六
行。次以冷水止之，冷主收敛故也。湿水既尽一、二日，煎
白虎汤，作顿啜之，疟犹不愈，候五、六日，吐之以常山散，去冷痰涎水六、七次，若翻浆
。次以柴胡汤和之，间用妙功丸磨之，疟悉除。
襄陵马国卿，病左乳下二胁间期门穴中发痈，坚而不溃，痛不可忍。医疡者皆曰
乳痈，或曰红系漏，或曰觑心疮，使服内托散百日，又服五香连翘汤数月，皆无验。国卿伛
偻而来，求治于戴人。遇诸市，戴人见之曰∶此马刀痈也。足少阳胆经之病，出《灵枢·十
二经》以示之。其状如马刀，故曰马刀。坚而不溃。乃邀之于食肆中，使食水浸汤饼。国卿曰∶
稍觉缓。次日，先以沧盐上涌，又以凉剂涤去热势，约数十行，肿已散矣。
又
朱葛黄家外家，左胁病马刀痈，憎寒发痛，已四五日矣。戴人适避暑于寺中。来乞药，戴人
曰∶此足少阳胆经病也。少血多气，坚而不溃，不可急攻。当以苦剂涌之，以五香连翘汤托
之。既而痛止，然痈根未散。有一盗医过，见之曰∶我有妙药，可溃而为脓，不如此，何时
而愈？既 毒药，痛不可忍，外寒内热，呕吐不止，大
便黑色，食饮不下，号呼闷乱，几至于死。诸姑惶惧，夜投戴人。戴人曰∶当寻元医者，余
不能治。其主母亦来告，至于再三。戴人曰∶胁间皮薄肉浅，岂可轻用毒药！复令洗出，以凉
剂下之，痛立止，肿亦消也。
小郑，十五岁，在田里中暑，出现头痛、困倦卧床无法起身的症状。戴人用双解散让他发汗，又喂他米醋汤，但病未解除。傍晚时分，又用三花神丸进行强力泻下，于是痊愈了。
另外，张叟七十一岁，在暑月于田间劳作，因饥饿和疲劳导致伤暑，饮食不进，时常呕吐，口中经常流出痰水，腹部和胁部疼痛。医生一概使用平胃散、理中丸、导气丸治疗，没有效果；后来又加上针灸，都说是胃寒所致，于是来请教戴人。戴人说：“痰属于胃，因为胃热不能收敛，所以流出口中的是痰水。考虑到您年事已高，不敢使用催吐法，于是让您用筷子探喉催吐，不通过服药就吐出了一升痰涎；接着用黄连清心散、导饮丸、玉露散来调理。饮食逐渐增加，只是大便仍然秘结，于是用生姜、大枣煎煮调胃承气汤一两，强力攻下，于是痊愈。”
所以，息城有一个男子患疟疾（Malaria），向戴人求治。诊察两手脉象，都沉伏而有力，体内有积滞，这是肥气（Feiqi, a type of abdominal mass）。病人说：“左胁下有肥气，肠中疼痛，积块也痛，形状像倒扣的杯子，时发时止，已经三年了，祈祷、躲避、隐匿，无所不用其极，始终不能治愈。”戴人说：“这是疟疾。”用三花神丸五七十丸，用冷水送服，排出五六次大便。接着再用冷水止泻，因为冷性主收敛的缘故。湿水排尽一两天后，煎煮白虎汤（Baihu Decoction），一次性喝完，疟疾仍未愈。等到第五六天，用常山散催吐，吐出冷痰涎水六七次，如同翻浆一般。接着用柴胡汤调和它，间或用妙功丸磨积，疟疾完全消除。
襄陵的马国卿，左侧乳房下方两胁之间的期门穴（Qimen, LR14）处发生痈肿，坚硬而不溃破，疼痛难以忍受。治疗疮疡的医生都说这是乳痈（Breast Abscess），有的说是红系漏，有的说是觑心疮，让他服用内托散一百天，又服用五香连翘汤几个月，都没有验证有效。马国卿驼着背前来，向戴人求治。在路上遇到戴人，戴人看见他说：“这是马刀痈（Horseshoe Carbuncle）。”这是足少阳胆经的疾病，出示《灵枢·十二经》给他看。其形状像马刀，所以叫马刀。坚硬而不溃破。于是邀请他在饭馆吃饭，让他吃用水浸泡的面条。马国卿说：“稍微觉得缓解了一些。”第二天，先用沧盐催吐，又用凉剂涤除热势，大约腹泻几十次，肿胀已经消散了。
另外，朱葛黄家亲戚，左胁患马刀痈，怕冷且疼痛，已经四五天了。戴人正好在寺庙避暑。他来乞求药物，戴人说：“这是足少阳胆经的疾病。气血特点是血少气多，坚硬而不溃破，不可急于攻伐。应当用苦味药催吐，用五香连翘汤托毒外出。不久疼痛停止，但是痈根尚未消散。有一个偷医路过的人，看见后说：‘我有妙药，可以使痈溃烂化脓，不这样做，什么时候能好？’用了毒药后，疼痛难以忍受，外寒内热，呕吐不止，大便黑色，饮食不下，号呼混乱，几乎致死。各位姑姑惊慌恐惧，夜里投奔戴人。戴人说：“应当寻找原来的医生，我不能治疗。”他的主母也来告知，反复多次。戴人说：“胁间皮肤薄肌肉浅，怎么能轻易使用毒药！”又让人洗去残留药物，用凉剂泻下，疼痛立刻停止，肿胀也消除了。”
Xiao Zheng, aged fifteen, suffered from heatstroke while working in the fields. He presented with headache and was too exhausted to get out of bed. Dai Ren administered Shuangjie San (Double Liberation Powder) to induce sweating, followed by Rice Vinegar Soup, but the condition did not resolve. In the late afternoon, he administered Sanhua Shen Wan (Three-Flower Divine Pill) for strong purgation, after which the patient recovered.
Furthermore, Zhang Sao, aged seventy-one, worked in the fields during the summer months. Due to hunger and fatigue, he suffered from heat injury. He had no appetite, vomited frequently, constantly drooled phlegm-water from his mouth, and experienced pain in the abdomen and hypochondrium. Physicians generally used Pingwei San (Calm the Stomach Powder), Lizhong Wan (Regulate the Middle Pill), and Daoqi Wan (Guide Qi Pill) without effect; acupuncture was also added, all attributing the symptoms to Cold of the Stomach. He then sought advice from Dai Ren. Dai Ren said, "Phlegm belongs to the Stomach. Because of Heat in the Stomach failing to contain fluids, phlegm-water flows out. Considering your advanced age, I dare not use emesis. Instead, I will have you stimulate the throat with chopsticks to induce vomiting without medication." The patient vomited one sheng of phlegm-saliva. Subsequently, Huanglian Qingxin San (Coptis Heart-Clearing Powder), Dao Yin Wan (Guide Drink Pill), and Yulu San (Jade Dew Powder) were used to regulate the condition. Food intake increased, but constipation persisted. Therefore, Tiaowei Chengqi Tang (Regulate the Stomach and Direct Downward Decoction), prepared with fresh ginger and jujube, was administered in a dosage of one liang for strong purgation, leading to recovery.
Thus, a man from Xicheng suffered from malaria (Nüe Ji) and sought treatment from Dai Ren. Palpation of both wrists revealed pulse positions that were deep, hidden, yet forceful, indicating internal accumulation. This is Feiqi (Abdominal Mass). The patient stated, "There is an Feiqi under the left hypochondrium causing pain in the intestines and the mass itself. It resembles an inverted cup, comes and goes intermittently, and has persisted for three years. I have prayed, avoided, and hidden myself in every possible way, yet it remains incurable." Dai Ren said, "This is malaria." He prescribed fifty to seventy pills of Sanhua Shen Wan, taken with cold water, resulting in five or six bowel movements. Then, cold water was used to stop diarrhea, as cold nature promotes contraction. After the damp-fluids were cleared for one or two days, Baihu Tang (White Tiger Decoction) was decocted and consumed in one dose, but the malaria did not resolve. Waiting until the fifth or sixth day, Dai Ren induced vomiting using Changshan San (Dichroa Powder), expelling cold phlegm-saliva six or seven times, resembling churning sludge. Subsequently, Chaihu Tang (Bupleurum Decoction) was used to harmonize the condition, interspersed with Miaogong Wan (Wonderful Merit Pill) to dissipate accumulations, completely eliminating the malaria.
Ma Guoqing from Xiangling developed a carbuncle (Yong) between the left breast and the hypochondrium, specifically at the Qimen acupoint (LR14). It was hard and did not suppurate, with unbearable pain. Physicians treating sores diagnosed it as Ru Yong (Breast Abscess), Hongxi Lou (Red Channel Fistula), or Xu Xin Chuang (Heart-Piercing Sore). They prescribed Neituo San (Internal Support Powder) for one hundred days and Wuxiang Lianqiao Tang (Five-Aromatic Forsythia Decoction) for several months, all without efficacy. Ma Guoqing came with a stooped back seeking Dai Ren's treatment. Dai Ren met him in the market and said, "This is Madao Yong (Horseshoe Carbuncle)." It is a disease of the Foot-Shaoyang Gallbladder Meridian, referencing *Lingshu: Twelve Meridians*. Its shape resembles a horseshoe, hence the name. It is hard and does not suppurate. Dai Ren invited him to a restaurant and had him eat noodles soaked in water. Ma Guoqing said, "I feel slightly relieved." The next day, Dai Ren first induced emesis using Cangyan (Sea Salt), then used cooling agents to purge heat, resulting in dozens of bowel movements, after which the swelling dissipated.
Furthermore, a relative of the Zhu Ge Huang family developed a Madao Yong on the left hypochondrium, accompanied by aversion to cold and pain, persisting for four or five days. Dai Ren happened to be避暑 (seeking coolness) in a temple. The patient came begging for medicine. Dai Ren said, "This is a disease of the Foot-Shaoyang Gallbladder Meridian. The constitution features little blood and much qi; it is hard and does not suppurate, so aggressive attack should not be rushed. One should use bitter agents to induce emesis and Wuxiang Lianqiao Tang to support the expulsion of toxins." Soon the pain stopped, but the root of the carbuncle had not dissipated. A thief-doctor passed by, saw the condition, and said, "I have a miraculous drug that can cause suppuration. Without this, when will it heal?" After using toxic drugs, the pain became unbearable, presenting with external cold and internal heat, incessant vomiting, black stools, inability to eat or drink, wailing and confusion, nearly reaching death. The various aunts were terrified and sought Dai Ren at night. Dai Ren said, "You should seek the original doctor; I cannot treat this." The mistress also came to report, repeatedly. Dai Ren said, "The skin is thin and muscles shallow in the hypochondrium; how can toxic drugs be used lightly!" He ordered the residue to be washed out and used cooling agents to purge downward. The pain stopped immediately, and the swelling subsided.
