常仲明病寒热往来，时咳一、二声，面黄无力，懒思饮食，夜多寝汗，日渐瘦削

断之曰∶上实也。先以涌剂吐痰二、三升，次以柴胡饮子，降火益水，不月余复旧。此证名何
？乃《内经》中曰二阳病也。二阳之病发心脾，不得隐曲。心受之，则血不流，故女子不月
；脾受之，则味不化，故男子少精，此二证名异而实合。仲明之病，味不化也。

鹿邑县一个世家大族，有一个二十三岁的儿子，患膏淋病已经三年了。当地的医生无法治愈。他前往京城四处求医，多数医生将其诊断为虚损证，采用温燥药物进行补益，并用针和艾条进行灸治，病情没有丝毫减轻。听说戴人（张从正的号）侨居在汴梁，便去拜见戴人。戴人说：“这是蛊惑之疾，也称为白淫。实际上是由于小腹冤热所致，并非虚证。可以用涌吐法来泄除邪气。”当时正值暑天，患者畏惧该疗法猛烈，犹豫了三天没有决定。一位僧人说：“我患有暑病，最近感觉头痛。”戴人说：“也可以用涌吐法。希望你与我一同接受此法，不要害怕。”于是通过涌吐排出痰液三升，颜色像黑矾汁，里面含有死血以及黄绿色的水。随后又腹泻排出积滞秽物数次，不久便觉得病愈。在他刚来时，面色苍白无血色，治疗结束后，第二天面色红润如醉酒一般。戴人担心他在暑月路途遥远，又开了几个方子，让他回去自行备药服用。
常仲明患寒热往来，偶尔咳嗽一两声，面色发黄，身体无力，懒得思考饮食，夜间多汗，日渐消瘦。各位医生都按虚损证治疗，使用二十四味烧肝散、鹿茸、牛膝等药物，补养了两年，导致口中痰多，下部更加虚弱。戴人诊断说：“这是上焦实证。”先用涌剂催吐，吐出痰液二到三升，接着用柴胡饮子，以降火益水，不到一个多月就恢复了健康。这个病症叫什么名字呢？《内经》中称为“二阳病”。二阳的病发于心脾，因有难以言说的隐曲之事。心受病，则血液不流通，所以女子闭经；脾受病，则食物不能运化，所以男子精少，这两个病症名称不同但实质相同。仲明的病，属于食物不能运化这一类。
黄家的孩子，面部赤红肿胀，双眼无法睁开。戴人用针刺轻刺放血的方法，除了两眼尖角外，乱刺数十针，出血三次后才痊愈。这种方法很多人不肯听从，一定要治病，就不能过于谨慎保护。
丹霞山的僧人，患头痛，常常住在暗室里，不敢见光亮。他的头部热痛，用布环围在头上，中间放置冰块，每天更换数次，热气仍不能消除。各位医生都不认识这个病症。他去求见戴人。戴人说：“这是三阳经蓄积热邪的缘故。”于是在温暖的房间里放置炭火，通过出汗、涌吐，三种方法并行，七天才痊愈。僧人对随从说：“这是神仙的手笔啊。”
In the county of Luyi, a young man from a prominent family, aged twenty-three, had suffered from *gaolin* (Gao Lin, creamy urine) for three years. Local physicians were unable to cure him. He traveled to the capital and sought treatment everywhere, but most doctors diagnosed it as *xusun* (Xu Sun, deficiency consumption) and treated him with warming and drying tonics, as well as acupuncture and moxibustion, without any reduction in symptoms. Hearing that Dairen (Zhang Congzheng's pseudonym) was residing in Bianliang, he went to see him. Dairen said, "This is a disease caused by bewitchment or confusion, also known as *baiyin* (Bai Yin, white turbidity). It is actually due to 'yuanre' (Yuan Re, unjustified heat) in the lower abdomen, not a deficiency. It can be treated by inducing vomiting to drain the pathogen." At that time, it was summer, and the patient feared the harshness of this method, hesitating for three days before making a decision. A Buddhist monk said, "I suffer from a summerheat disease and recently felt headache." Dairen said, "Vomiting can also be used for you. I wish for you to undergo it with me; do not be afraid." Consequently, three sheng (a traditional unit of volume) of phlegm were vomited out, dark like iron sulfate juice, containing dead blood and yellow-green fluid. Subsequently, several bowel movements of accumulated filth were discharged, and soon after, he felt cured. When he first arrived, his face lacked color; after treatment, the next day his face looked flushed as if drunk. Dairen, fearing the long journey during the hot season, prescribed several formulas for him to take home for self-preparation.
Chang Zhongming suffered from alternating chills and fever, occasional coughing (one or two times), sallow complexion, weakness, aversion to food and drink, night sweats, and progressive emaciation. Various physicians treated him as a deficiency consumption case, using Ershisiwei Shaogan San (Twenty-Four-Ingredient Roasted Liver Powder), Lu Rong (Cervus Nippon Antler), and Niu Xi (Achyranthes Bidentata Root), tonifying him for two years. This resulted in excessive phlegm in the mouth and further deficiency in the lower body. Dairen diagnosed it as: "Excess in the upper jiao." First, he used an emetic agent to expel two to three sheng of phlegm. Then, he administered Chaihu Yinzi (Bupleurum Decoction) to descend fire and benefit water. Within a little over a month, he recovered. What is this syndrome named? In the *Neijing* (Classic of Internal Medicine), it is called "Eryang Bing" (Disease of the Two Yangs). Diseases of the Eryang originate from the heart and spleen, often associated with unspoken distress. If the heart is affected, blood flow stagnates, leading to amenorrhea in women; if the spleen is affected, food transformation fails, leading to scanty essence in men. These two syndromes have different names but share the same essence. Zhongming's illness belongs to the category of failed food transformation.
The child of the Huang family had a red and swollen face with eyes unable to open. Dairen used light needle pricking and bloodletting. Except for the corners of the eyes, dozens of needles were inserted randomly, and after bleeding three times, he was cured. Many people are unwilling to follow this method; if one insists on curing the disease, one cannot be overly cautious or protective.
A monk from Danxia Mountain suffered from headache and usually stayed in a dark room, afraid to see light. His head was hot and painful; he wrapped cloth around his head and placed ice inside, changing it several times a day, yet the heat could not be alleviated. Physicians did not recognize the syndrome. He sought an audience with Dairen. Dairen said, "This is due to accumulated heat in the Three Yang meridians." Therefore, charcoal fires were placed in a warm room, and sweating, vomiting, and purging methods were applied simultaneously. After seven days, he was cured. The monk said to his attendant, "This is the work of immortals."
