显庆寺僧应公，有沉积数年，虽不卧床枕，每于四更后，心头闷硬，不能安卧，
须起行寺中，习以为常，人莫知为何病，以药请于戴人。戴人令涌出胶涎一、二升，如黑
矾水，继出黄绿水，又下脓血数升。自尔胸中如失巨山，饮饵无算，安眠至晓。
一缁侣，好茶成癖，积在左胁。戴人曰∶此与肥气颇同。然
疟不作，便非肥气。虽病十年，不劳一日。况两手脉沉细，有积故然。吾治无针灸之苦，但小恼一饷，可享寿
尽期。先以茶调散，吐出宿茶水数升；再以木如意
又涌数升，皆作茶色；次以三花神 丸九十余粒，是夜泻二十余行，脓水相兼，燥粪瘀血，
杂然而下；明日以除湿之剂，服十余日，诸苦悉蠲，神清色莹。
蹙 张承应，年几五十，腹如孕妇，面黄食减，欲作水气。或令
服黄 建中汤及温补之剂，小溲涸闭，从戴人疗焉。戴人曰∶建中汤，攻表之药也。古方用之攻里，已
误也，今更以此取积，两重误也。先以涌剂吐之，置火于其旁，大汗之；次与猪肾散四钱
，以舟车丸引之，下六缶，殊不困；续下两次，约三十余行，腹平软，健啖如昔。常仲明曰
∶向闻人言，泻五、六缶，人岂能任？及闻张承应，渠云诚然。乃知养生与攻 ，本自不同。今人以补
剂疗病，宜乎不效。
显庆寺的僧人应公，体内有积滞沉积了数年，虽然不需要卧床休息，但每到凌晨四更之后，心头感到闷胀坚硬，无法安稳躺卧，必须起身在寺中行走，这已成为常态，人们不知道这是什么病，便向戴人（张从正）求药治疗。戴人让他使用涌吐法，吐出了胶状涎液一、二升，颜色像黑矾水一样，接着又吐出黄绿色的液体，随后又排出了几升脓血。从此以后，他感觉胸中好像失去了巨大的山峦般沉重，饮食无数，能够安睡到天亮。
另一位僧侣，喜爱喝茶成癖，积滞停留在左胁部。戴人说：“这与肥气（一种积聚病证）颇为相似。然而如果不发作疟疾症状，就不是肥气。虽然患病十年，却并不劳累一天。况且两手脉象沉细，是因为有积滞的缘故。我治疗没有针灸的痛苦，只是稍微让人烦恼一会儿，就可以享尽天年。”先用茶调散，吐出了宿存的茶水几升；再用木如意（一种催吐工具）继续涌吐数升，都呈现茶色；接着服用三花神丸九十余粒，当晚腹泻二十多次，脓水和粪便混杂而下，燥屎和瘀血也杂乱地排出；第二天服用祛湿的药剂，服用了十几天，所有的痛苦都消除了，精神清爽，面色晶莹。
蹙张承应，年龄接近五十岁，腹部大得像孕妇一样，面色发黄，食欲减退，想要当作水气病（水肿类疾病）治疗。有人让他服用黄芪建中汤及温补的药剂，导致小便干涸闭塞，于是来找戴人治疗。戴人说：“建中汤，是用于解表的药物。古方用它来攻里，已经是错误的，现在更用此药来消除积滞，是双重错误。”先用涌吐剂让他呕吐，并在旁边放置火盆，使其大汗出；接着给予猪肾散四钱，以舟车丸作为引导，排泄了六缶（古代量器，此处指大量粪便），身体一点也不困倦；随后又排泄了两次，大约三十多次，腹部变得平坦柔软，饮食健旺如从前。常仲明说：“以前听人说，泻下五、六缶，人怎么能承受得住？等到听到张承应的情况，他说确实如此。才知道养生与攻邪，本来就有不同。现在的人用补剂来治病，当然不效验。”
The monk Ying Gong of Xingqing Temple had suffered from internal accumulation for several years. Although he did not need to stay in bed, every night after the fourth watch (around 1-3 AM), he felt stuffiness and hardness in his chest, making it impossible to sleep peacefully. He had to get up and walk around the temple, a habit that became routine. People did not know what disease this was, so they sought medicine from Dairen (Zhang Congzheng). Dairen instructed him to undergo emesis (induced vomiting), which expelled one or two sheng (ancient unit of volume) of gelatinous phlegm, resembling black alum water, followed by yellow-green fluid, and then several sheng of pus and blood. From then on, he felt as if a huge mountain had been removed from his chest; he could eat and drink without limit and slept soundly until dawn.
Another monk had developed an addiction to tea, with the accumulation lodged in his left hypochondrium. Dairen said, "This is quite similar to Feiqi (a type of abdominal mass/accumulation). However, since malaria-like symptoms do not occur, it is not Feiqi. Although he has been ill for ten years, he does not feel fatigued for even a day. Moreover, his pulses in both hands are deep and fine, which is due to the presence of accumulation. My treatment involves no pain from acupuncture or moxibustion; it only causes slight discomfort for a moment, allowing him to live out his natural lifespan." First, Cha Tiao San (Tea Regulating Powder) was used to induce vomiting, expelling several sheng of old tea residue; then, using a wooden emetic tool (Mu Ruyi), further emesis was induced, expelling several more sheng of liquid that appeared tea-colored; next, over ninety pills of Sanhua Shen Wan (Three-Flower Divine Pill) were administered. That night, he experienced diarrhea more than twenty times, with pus and water mixed together, along with dry feces and stagnant blood being discharged chaotically. The following day, dampness-resolving formulas were taken for over ten days, eliminating all suffering, leaving him with clear spirit and lustrous complexion.
Zhang Chengying, aged nearly fifty, had an abdomen distended like that of a pregnant woman, with sallow complexion and reduced appetite. It was suspected to be Shuiqi (water qi/edema). Some advised taking Huangqi Jianzhong Tang (Astragalus Middle-Jian Decoction) and other warming and tonifying agents, which resulted in scanty and obstructed urination. He then sought treatment from Dairen. Dairen said, "Jianzhong Tang is a formula for releasing the exterior. Using it internally to attack interior pathogens in ancient prescriptions was already a mistake; using it now to eliminate accumulation is a double error." First, an emetic agent was used to induce vomiting, with fire placed beside him to induce profuse sweating; then, Zhu Shen San (Pig Kidney Powder) four qian was given, guided by Zhouche Wan (Boat Cart Pill), resulting in the discharge of six fan (ancient vessel/unit) of stool, without any feeling of fatigue; subsequently, two more episodes of purgation occurred, totaling about thirty times, leading to a flat and soft abdomen and a return to normal hearty appetite. Chang Zhongming said, "I had heard people say that purging five or six fan of stool would be unbearable for a person. Upon hearing Zhang Chengying's case, he confirmed it was true. Thus, I realized that nourishing life (tonification) and attacking pathogenic factors (purging) are fundamentally different. Nowadays, people use tonifying agents to treat diseases, which explains why they are often ineffective."
