古郾一讲僧，病泄泻数年，丁香、豆蔻、干姜、附子、官桂、乌梅等燥药，燔针
、烧脐、 腕，无有阙者。一日，发昏不省，檀那赠纸者盈门。戴人
诊其两手脉，沉而有力。《脉诀》云∶下利，脉微小者生，洪浮大者无瘥。以瓜蒂散涌之，出
寒痰数升；又以无忧散，泄其虚中之积及燥粪，仅盈斗；次以白术、调中汤、五苓散、益元散，调理
数日，僧已起矣。非术精识明，谁敢负荷如此？
一讲僧显德明，初闻家遭兵革，心气不足，又为寇贼所惊，得脏腑不调。后入京
，不伏水土，又得心气，以至危笃。前后三年，八仙丸、鹿茸丸、烧肝散，皆服之，不效。
乃求药于戴人。戴人曰∶此洞泄也。以谋虑久不决而成。肝主谋虑，甚则乘脾，久思则脾湿下流
。乃上涌痰半盆，末后有血数点，肝藏血故也。又以舟车丸、浚川散，下数行，仍使澡浴
出汗。自尔日胜一日，常以胃风汤、白术散，调养之，一月而强，食复故矣。
又 李德卿妻，因产后病泄一年余，四肢瘦乏，诸医皆断为死证。当时戴人在朱葛寺，以舟载而乞治焉。戴
人曰∶两手脉皆微小，乃痢病之生脉。况洞泄属肝经，肝木克上而成。此疾亦是肠 。 者
，肠中有积水也。先以舟车丸四、五十粒，又以无忧散三、四钱，下四、五行。寺中人皆
骇之∶病羸如此，尚可过耶？众人虽疑，然亦未敢诮，且更看之。复导饮丸，又过之，渴则
调以五苓散。向晚使人伺之，已起而缉床，前后约三、四十年。以胃风汤调之，半月
而能行，一月而安健。由此阖寺服，德卿之昆仲咸大异之。
又 刘德源，病洞泄逾年，食不化，肌瘦力乏，行步欹倾，面色黧黑。举世治痢之药，皆用之
，无效。适戴人莅HT 隐阳，往问之。戴人乃出示《内经》
洞泄之说。虽已不疑，然畏其攻剂。夜焚香祷神曰∶某以病久不瘥，欲求治于戴人，戴人
以谓宜下之。欲不从，戴人，名医也；欲从之，形羸如此，恐不任药。母已老矣，无人侍养
，来日不得已须服药，神其相之。戴人先以舟车丸、无忧散，下十余行，殊不困，已颇喜食；后以槟榔丸
，磨化其滞。待数日，病已大减。戴人以为去之未尽，当以再服前药，德源亦欣然请下之。又下
五行，次后数日，更以苦剂越之。往问其家，彼云已下村中收索去也。忽一日入城，面色极
佳，语言壮健，但怪其跛足而立。问何故如此。德源曰∶足上患一疖。戴人曰∶此里邪去而
外现。病痊之后，凡病皆如是也。
古郾地有一位讲经的僧人，患泄泻病数年之久。丁香、豆蔻、干姜、附子、官桂、乌梅等燥热药物，以及燔针（烧红的针）、烧脐（在肚脐上施灸或烧灼）等疗法，没有一样没用过的。一天，他忽然昏厥不省人事，前来赠送纸钱祭奠的人挤满了门庭。戴人（张从正）诊察他的两手脉象，沉而有力。《脉诀》说：“下利（腹泻），脉象微小者生，洪浮大者无痊愈之望。”于是用瓜蒂散（Coturnia Decoction）催吐，吐出寒痰数升；又用无忧散（Wuyou Powder）攻下，排出虚中积滞及干燥粪便，仅满一斗；随后用白术（Atractylodis Macrocephalae Rhizoma）、调中汤（Tiaozhong Decoction）、五苓散（Wuling Powder）、益元散（Yiyuan Powder）调理数日，僧人已康复。若非医术精湛、见识高明，谁敢承担如此重任？
另一位讲僧显德明，起初听说家中遭遇战乱，心气不足，又被寇贼惊吓，导致脏腑功能失调。后来进入京城，不服水土，又患上心气病，病情危重。前后三年间，八仙丸（Baxian Pill）、鹿茸丸（Lurong Pill）、烧肝散（Shaogan Powder）都服用过，均无效。于是向戴人求药。戴人说：“这是洞泄（一种严重的腹泻）。因谋虑久决不定而成。肝主谋虑，甚则乘脾（肝木克伐脾土），久思则脾湿下流。”于是先涌吐痰液半盆，最后有几滴血，这是因为肝藏血的缘故。又用舟车丸（Zhouche Pill）、浚川散（Jun chuan Powder）攻下数次，仍让他洗澡出汗。从此病情一日胜过一日，常以胃风汤（Weifeng Decoction）、白术散（Baizhu Powder）调养，一个月后身体强健，饮食恢复如常。
又有李德卿的妻子，因产后患泄泻一年多，四肢消瘦乏力，众医都断定为死证。当时戴人在朱葛寺，人们用船载着她来乞求治疗。戴人说：“两手脉皆微小，这是痢病（此处指严重泄泻类疾病）尚有生机的脉象。况且洞泄属肝经，是肝木克伐脾土所致。此疾也是肠澼（Changpi，指肠道有积水的泄泻病）。肠澼者，肠中有积水也。”先用舟车丸四五十粒，又用无忧散三四十钱，攻下四五次。寺中人都对此感到惊骇：病人如此虚弱，还能承受得住吗？众人虽怀疑，但也不敢嘲笑，且继续观察。又用导饮丸（Daoyin Pill）攻下，口渴时用五苓散调和。傍晚派人去查看，她已经起身整理床铺了，前后大约三四十年（形容病程之长或痛苦之久，此处语境似指长期卧床后的首次活动，或原文“三十年”为夸张或笔误，依文意译为长期病痛后的恢复）。用胃风汤调理，半个月能行走，一个月就安健了。由此全寺的人都信服，李德卿的兄弟们都对此大为惊奇。
又有刘德源，患洞泄一年多，食物不消化，肌肉消瘦，体力匮乏，走路倾斜不稳，面色黧黑。世间治疗痢疾的药物都用过了，无效。恰逢戴人到隐阳任职，前去询问。戴人便出示《内经》中关于洞泄的说法。虽然已不再怀疑，但仍畏惧攻下剂。夜里焚香祷告神灵说：“我因病久不愈，想求治于戴人，戴人说宜用攻下法。想不服从，戴人是名医；想服从，身体如此羸弱，恐怕不能耐受药物。母亲已老，无人侍养，明天不得已必须服药，希望神灵保佑。”戴人先用舟车丸、无忧散，攻下十多次，病人并不困倦，反而颇喜进食；后用槟榔丸（Binglang Pill）磨化其积滞。等待数日，病情已大减。戴人认为邪气未除尽，应当再服前药，德源也欣然请求攻下。又攻下五次，此后数日，再用苦剂催吐以越之。去他家询问，家人说他已经下到村里收索去了（意指病情好转，自行外出）。忽然有一天进城，面色极佳，语言壮健，只是奇怪他跛足站立。问为何如此。德源说：“脚上长了一个疖子。”戴人说：“这是里邪（体内病邪）去除而在外显现。病痊愈之后，凡病都是这样的。”
In the ancient place of Yanyan, a monk who lectured on scriptures suffered from diarrhea for several years. He had used all sorts of drying and warming herbs such as Dingxiang (Caryophylli Flos), Doukou (Amomi Fructus Rotundus), Ganjiang (Zingiberis Rhizoma), Fuzi (Aconiti Lateralis Radix Praeparata), Guigui (Cinnamomi Ramulus), and Wumei (Mume Fructus), as well as treatments like burning needles (Fanzhen) and cauterizing the navel (Shaoqi). None were omitted. One day, he suddenly fell into a coma and lost consciousness. The number of lay donors (Tan na) bringing paper money to offer sacrifices filled the courtyard. Dairen (Zhang Congzheng) examined his pulses at both wrists; they were deep and forceful. The *Maijue* (Pulse Classic) states: "In diarrhea, if the pulse is minute and small, there is hope for life; if it is surging, floating, and large, there is no prospect of recovery." Dairen administered Guiti San (Coturnia Powder) to induce vomiting, expelling several sheng (a unit of volume) of cold phlegm. He then used Wuyou San (Wuyou Powder) to purge the accumulation in the deficiency center and dry feces, which amounted to nearly one dou (a unit of volume). Subsequently, he regulated the patient's condition over several days using Baizhu (Atractylodis Macrocephalae Rhizoma), Tiaozhong Tang (Regulating the Middle Decoction), Wuling San (Five-Ingredient Powder with Poria), and Yiyuan San (Benefiting Origin Powder). The monk recovered. Without exquisite skill and clear insight, who would dare to undertake such a case?
Another lecturing monk, Xian Deming, initially heard that his family had suffered from war, leading to insufficiency of Heart Qi. He was further frightened by bandits, resulting in disharmony of the Zang-Fu organs. Later, upon entering the capital, he failed to adapt to the local water and soil, developing Heart Qi disease until his condition became critical. Over three years, he took Baxian Wan (Eight Immortals Pill), Lurong Wan (Deer Antler Pill), and Shaogan San (Burned Liver Powder), but none were effective. He then sought treatment from Dairen. Dairen said, "This is Dongxie (Cavity Diarrhea). It arises from prolonged deliberation without resolution. The Liver governs deliberation; when excessive, it overacts on the Spleen. Prolonged thinking causes Spleen dampness to flow downward." Dairen first induced vomiting, expelling half a basin of phlegm, with a few drops of blood appearing at the end, which is because the Liver stores blood. He then used Zhouche Wan (Boat and Cart Pill) and Junchuan San (River-Dredging Powder) to purge him several times, and still made him take a bath to sweat. From that day on, his condition improved daily. He was regularly nourished with Weifeng Tang (Stomach Wind Decoction) and Baizhu San (Atractylodes Powder). Within one month, his strength returned, and his appetite recovered to normal.
There was also the wife of Li Deqing, who suffered from diarrhea for over a year postpartum. Her limbs were emaciated and weak, and all physicians diagnosed it as a fatal syndrome. At that time, Dairen was at Zhuge Temple. She was transported by boat to beg for treatment. Dairen said, "The pulses at both wrists are minute and small, which is a vital pulse for dysentery-like diseases. Moreover, Dongxie belongs to the Liver Meridian, caused by Liver Wood overacting on Earth. This illness is also Changpi (Intestinal Dysentery/Water Accumulation in Intestines). Changpi refers to water accumulation in the intestines." He first administered 40-50 pills of Zhouche Wan, followed by 3-4 qian of Wuyou San, causing four or five purgations. The temple people were horrified: "With the patient so debilitated, can she withstand this?" Although the crowd doubted, they dared not mock and decided to wait and see. He then used Daoyin Wan (Guiding Drink Pill) to purge her again. When she was thirsty, he regulated her with Wuling San. In the evening, someone was sent to check, and she had already risen and tidied her bed. [Note: The text mentions 'three or forty years', likely referring to the duration of suffering or a textual anomaly, interpreted here as long-term affliction]. With Weifeng Tang for regulation, she could walk after half a month and was healthy after one month. Consequently, the entire temple accepted his treatment, and Li Deqing's brothers were greatly amazed.
Furthermore, Liu Deyuan suffered from Dongxie for over a year. Food was not digested, muscles were emaciated, strength was lacking, gait was unsteady and tilted, and complexion was dark. All medicines in the world for treating dysentery had been used without effect. Coincidentally, Dairen arrived at Yinyang for official duties, and Liu went to consult him. Dairen showed him the explanation of Dongxie in the *Neijing* (Inner Canon). Although Liu no longer doubted, he feared the purgative agents. That night, he burned incense and prayed to the gods: "My illness has persisted for a long time without cure. I wish to seek treatment from Dairen, who says purgation is appropriate. If I do not comply, Dairen is a famous doctor; if I do comply, my body is so frail that I fear I cannot tolerate the medicine. My mother is old, and there is no one to care for her. Tomorrow, I will have no choice but to take the medicine. Please, Spirit, protect me." Dairen first used Zhouche Wan and Wuyou San, causing more than ten purgations. The patient was not exhausted and actually began to enjoy eating. Afterwards, Binglang Wan (Areca Seed Pill) was used to dissolve stagnation. After a few days, the illness decreased significantly. Dairen believed the pathogenic factors were not completely eliminated and should take the previous medicines again. Deyuan happily agreed to be purged. He was purged five more times. In the following days, a bitter agent was used to induce vomiting. Dairen visited his home to inquire, and the family said he had gone down to the village to collect things. Suddenly, one day he entered the city. His complexion was excellent, and his speech was robust, but he stood with a limp. When asked why, Deyuan said, "I have a boil on my foot." Dairen said, "This is the internal pathogen leaving the interior and manifesting externally. After recovery from any illness, this is how it happens."
