人参白虎、生脉散等方，皆中暑门中要剂，俱有人参，又何虑之有。乃殊不信，复理喻再三，乃终不信。欲辞
去，而阻于豪雨，强留午餐。因再谓曷不就此时如议进药，脱有不安，可用法立解也。于是勉从以进，犹惴惴
焉，惟恐增胀。既而殊宁静，超时神思少清，间吐一二语，始用参不疑。调治浃旬，竟得全愈。
陈子佩治一人，八月间，发热谵语，不食又不大便。诸医皆以为伤寒，始而表，继而下，俱不应。延至五
十余日，投以人参，热稍减，参少则又复热。于是益疑其虚也，峻补之，然不食不便如故。诊之，六脉平和，
绝无死状。谓伤寒无五十日不便不食而不死之理，闻病者夏月治丧，往来奔走，必是中暑无疑。误以伤寒治之，
又投以人参补剂，暑得补而愈不解，故至此耳。当以六一散以凉水调服，病者欲之，虽多不妨。服已即睡，睡
醒即便，便后思食，数日而愈。
吴桥治吴鸿胪妻，年三十，形故肥，当暑而飧如常，诘朝不起。启视之，瞑目昏愦，口舌唇吻，皆色深黑，
痰如鼓 有声，勺饮不能下咽，即千金药无所用。逆桥至，六脉浮濡，谓鸿胪曰∶是本风痰兼中暑故尔。即以
浓朴香薷饮，灌牛黄丸。辄能下，痰声必杀。更进，少顷黑色退而为黟。薄暮色如羊肝，诘朝但微紫。于是加
补剂，五日始张目能言。逾日如故。（《太函集》。）
章虚谷治周小梅室，六月中感暑邪，身热五日，始延李先生，服疏散一剂，次日病更甚。更医，闻得大便
数日不解，即用大黄数钱，鲜生地尤重用，柴胡、浓朴等服之，便下两次，病患自觉爽快。惟晡时发冷，黄昏
发热，至天明方休，彻夜不寐。章诊之，询知病由，曰∶暑为火湿合化，湿系阴邪，遏热不达。李先生用疏散，
则湿开热透，并不错误。乃反误投下剂，使邪陷入阴，故夜热而昼不热，则病势重矣。邪既入阴，欲其转阳甚
难，只可转其枢机，兼从阴厘清其邪热。乃用草果、苍术、浓朴醒脾开湿透膜原，柴胡以转少阴之枢，青蒿、
鳖甲、知母、黄柏清阴分之热。服两日，不效，其脉虚软无力，口甚渴，饮茶不绝，腹满，大小便皆不利，粒
米不进，稍饮米汤，口即作酸。此中气大伤，乃于前方去知母加参，又服两日，小便稍利，诸症不减，脉软少
神，不进谷食，已十二日矣。再延数日，胃气绝，则不可救。因其脾肾两伤，元气无权，三焦气化失职，邪反
内闭。盖肾伤无开阖之力则便阻，脾伤而转运不前则腹满。阳既委顿，则津液不生，故渴甚，非用附子、干姜，
大助其阳，则邪终不化。乃用党参、草果、苍术、浓朴、附子、干姜、生姜、乌梅、白芍，稍加黄连，服两日，
腹满减而便下溏粪如胶浆，略进稀粥。又服两日，腹满消而粥食大进，小溲亦长。惟夜热如故，冷则无矣。此
湿已化，但有热邪，乃于前方去附子、乌梅，加知母三钱，生石膏五钱，服两日，热全退，即用清补调理而安。
藜按∶此证误下之后，热去湿留，徒伤其脾胃。究竟湿中之热，亦未能尽去。脾胃既伤，值午后阳衰之
时，故发冷。热陷湿中，扰其营气，故发热，夜不成寐。湿热阻滞气机，则津液不生，故口渴。斯时宜用
渗淡之品，加芳香醒脾之药，病可立愈。乃以燥剂劫之，又增入寒凉药，益伤其脾，故不效。继乃大用辛
燥以劫之，脾气得辛燥之药而有权，湿为刚燥所劫而胥化，故仍以寒药收功。此将差就错之治，未可以为
准则也。方中乌梅、白芍尤为无谓。先生自谓从乌梅丸变化而来，亦欺人之语。
萧山何某，夏月不爽，自谓受暑，食西瓜一枚，又服凉药数帖。后无所苦，惟胃不开，每日强饮薄粥一二钟，
甚无味，尚行动自如，小便淡黄，大便干，多日不解，胸腹无胀闷，面色如常，舌光红而无苔，酷似胃阴不足。
但不喜汤饮，脉则浮中皆无，按之至骨，萦萦如蛛丝。医者犹欲进凉药。曰∶此证固非邪火，亦非胃阴不足，
乃元阳大亏之症。幸小便淡黄，大便坚固，肾气坚，为有根，再服凉药必死。遂用附子理中汤去术，加当归、
桂枝以养营。数剂，毫无效验。又去桂枝，加肉桂、吴萸、黄 ，连服十余剂，依然如故。又进前药十余剂，
仍复如前。细思其小便通，大便干，则肾元未绝，何以胃总不开？令停药四五日，亦只如是。乃屏去热药，重
用鹿角胶，佐以枸杞、当归、参、 、苁蓉、广陈等，湿润养阳。十剂，肺脉稍和，饮食略加。又十剂，胃始
开，便始通，其人反软弱不能起坐。又养半月，始得下床。
一人面白体盛，夏月患暑，服凉解两帖而愈，以邪轻故也。旬日复感，自服苏合丸，覆被发汗，津液大泄，
热邪内陷，又兼少年多欲，脉空数无根。章曰∶苏合丸辛温走窜治寒尚可，温暑大忌。勉进甘凉薄味之药，养
阴和阳。四五日，脉稍转，而尺部甚空。身热不退，夜则谵语，天明则清，舌有薄苔，边淡黄，中白滑，每日
饮粥二三碗。十余日，病不增减。药稍疏利，则委顿不堪。稍补助，则邪热愈炽。一日，因换床，即大汗口开，
眼闭欲脱。用熟地一两二钱，附子四钱，浓朴二钱，合二陈汤如数，煎一大碗，黄昏时，服一半即熟寐。二更
醒后，又服一半，亦无所觉。子后仍谵语，天明则清。脉稍有神而加数，舌苔中心亦黄，（附子之故。）胸腹仍宽，
能进粥食，乃用白虎汤加细生地等。连服数日，脉渐好，粥稍加。惟身热不退，夜仍谵语，左关脉独滞且沉。
因思昼清夜昏，为热入血室。血室厥阴所主，故左关独滞。仲圣有刺期门之法，是邪结血分也，今不明刺法，
乃用归须、赤芍、新绛、青蒿、鳖甲、柴胡、黄芩、细生地之类。五六服，全然不效，此时已一月有二日矣。
因病家笃信不获辞，彻夜思之，未得其理。忽记来复丹方中，有灵脂专入厥阴。暑湿浊邪，与伤寒不同，故前
药不效。灵脂以浊攻浊，兼有硝、黄，直达至阴，助本元以祛邪，必当奏功。遂于前方去柴胡，送来复丹一钱，
夜即安睡，无谵语。连进三服，身热即退。忽解小便甚长，色深碧稠如胶浆，病家惊询。章曰∶此病根除矣。
因其少年多欲，湿之邪乘虚陷入肝肾，故与伤寒之热入血室，病同而邪不同，故药力不能胜邪则不效。此来复
丹以浊攻浊，所以神效也。后进补药而愈。
人参白虎汤、生脉散等方剂，都是治疗中暑的重要药物，其中都含有的人参，又有什么可担忧的呢？（患者）却完全不相信，（我）反复劝说了多次，他始终不信。（我）想告辞离开，却被豪雨阻挡，强行留下吃午餐。于是再次对他说：“何不就在此时按照商议好的方案服药？倘若感到不适，可以用方法立刻解除。”于是勉强听从并服下，心中仍惴惴不安，唯恐增加腹胀。不久后病情特别安宁，过了超时神思稍微清醒，偶尔说一两句活，才开始不怀疑用人参。调理治疗十天，竟然完全痊愈。
陈子佩治疗一个人，八月间，发热且胡言乱语，不吃东西也不大便。众医生都认为是伤寒，起初用解表法，接着用泻下法，都不见效。拖延到五十多天，投用人参，热势稍减，人参减量则热势又复起。于是更加怀疑他是虚证，用峻猛的补药，然而不吃不便如故。诊察他的脉象，六脉平和，完全没有死状。说伤寒没有五十天不大便、不吃东西而不死的道理，听说病人在夏天治丧，往来奔走，必定是中暑无疑。误用治疗伤寒的方法，又投以人参补剂，暑邪得到补益而更加不解，所以到了这种地步。应当用六一散用凉水调服，病人想要这样，即使多吃也无妨。服后即刻睡觉，睡醒后大便通畅，便后想吃东西，几天后痊愈。
吴桥治疗吴鸿胪的妻子，三十岁，身体向来肥胖，当暑天饮食如常，第二天早晨不起床。打开查看，闭目昏沉迷糊，口舌嘴唇颜色深黑，痰鸣如鼓声，勺子喂水不能咽下，即使是千金方里的药也无从使用。迎接吴桥来诊治，六脉浮而濡软，对吴鸿胪说：“这是本有风痰兼之中暑的缘故。”随即用浓朴香薷饮，灌服牛黄丸。药能下咽，痰声必然减弱。再进药，片刻后黑色退去变为黝黑。傍晚颜色像羊肝，第二天早晨只是微紫。于是加上补剂，五天开始睁眼能说话。过了一天恢复如常。（出自《太函集》。）
章虚谷治疗周小梅的妻子，六月间感受暑邪，身热五天，才请李先生，服用疏散药一剂，第二天病更重。换医生，听说大便几天不解，即用大黄数钱，鲜生地重用，柴胡、浓朴等药服用，大便下了两次，病患自觉爽快。只有下午发冷，黄昏发热，到天亮才停止，整夜不睡觉。章虚谷诊察，询问得知病因，说：“暑是火与湿化合而成，湿属于阴邪，遏制热邪使其不能透达。李先生用疏散法，则湿气开泄热邪透出，并不错误。反而误用泻下剂，使邪气陷入阴分，所以夜间发热而白天不发热，那么病势就重了。邪气既入阴分，想要它转回阳分很难，只能转动枢机，同时从阴分清解其邪热。”于是用草果、苍术、浓朴醒脾开湿透膜原，柴胡以转动少阴之枢机，青蒿、鳖甲、知母、黄柏清阴分之热。服用两天，无效，脉象虚软无力，口很渴，不断喝茶，腹部胀满，大小便都不利，一粒米不进，稍微喝点米汤，口即作酸。这是中气大伤，于是在前方去掉知母加入人参，又服两天，小便稍利，诸症不减，脉软少神，不进谷食，已经十二天了。再拖几天，胃气绝，就不可救了。因为脾肾两伤，元气无权，三焦气化失职，邪气反而内闭。大概肾伤没有开阖之力则大便阻滞，脾伤而转运不前则腹部胀满。阳气既已委顿，则津液不生，所以口渴严重，不用附子、干姜，大助其阳气，则邪终不能化解。于是用党参、草果、苍术、浓朴、附子、干姜、生姜、乌梅、白芍，稍加黄连，服用两天，腹部胀满减而大便下溏粪如胶浆，略进稀粥。又服两天，腹满消而粥食大增，小便也长。只有夜间发热如故，发冷就没有了。这湿气已化，但有热邪，于是在前方去掉附子、乌梅，加知母三钱，生石膏五钱，服用两天，热全退，即用清补调理而安。
藜按：此证误用泻下之后，热去湿留，徒然损伤脾胃。究竟湿中之热，也未能尽去。脾胃既伤，正值午后阳气衰弱之时，所以发冷。热陷湿中，扰乱营气，所以发热，夜间不能入睡。湿热阻滞气机，则津液不生，所以口渴。此时宜用渗淡之品，加芳香醒脾之药，病可立愈。却用燥剂劫夺，又增入寒凉药，更加损伤其脾，所以无效。继而乃大用辛燥之药以劫夺，脾气得辛燥之药而有权，湿为刚燥所劫而全部化解，所以仍以寒药收功。这是将差就错的治疗，不可以作为准则。方中乌梅、白芍尤为无谓。先生自称是从乌梅丸变化而来，也是欺人之语。
萧山何某，夏月身体不适，自认为受暑，吃西瓜一枚，又服凉药数帖。后来无其他痛苦，只有胃口不开，每天强饮薄粥一二钟，甚无味，尚行动自如，小便淡黄，大便干，多日不解，胸腹无胀闷，面色如常，舌光红而无苔，酷似胃阴不足。但不喜欢汤饮，脉象浮取中取皆无，按之至骨，萦萦如蛛丝。医者还想进凉药。（何某）说：“此证固然不是邪火，也不是胃阴不足，乃是元阳大亏之症。幸好小便淡黄，大便坚固，肾气坚，为有根，再服凉药必死。”遂用附子理中汤去白术，加当归、桂枝以养营血。数剂，毫无效验。又去桂枝，加肉桂、吴茱萸、黄芪，连服十余剂，依然如故。又进前药十余剂，仍复如前。细思其小便通，大便干，则肾元未绝，何以胃总不开？令停药四五日，也只如是。于是屏去热药，重用鹿角胶，佐以枸杞、当归、人参、黄芪、肉苁蓉、广陈皮等，湿润养阳。十剂，肺脉稍和，饮食略加。又十剂，胃始开，便始通，其人反软弱不能起坐。又养半月，始得下床。
一人面白体盛，夏月患暑，服凉解药两帖而愈，因为邪气轻的缘故。旬日后再次感邪，自服苏合丸，盖被发汗，津液大泄，热邪内陷，又兼少年多欲，脉空数无根。章虚谷说：“苏合丸辛温走窜，治寒尚可，治暑大忌。”勉强进甘凉薄味之药，养阴和阳。四五日，脉稍转，而尺部甚空。身热不退，夜间则胡言乱语，天明则清醒，舌有薄苔，边淡黄，中白滑，每日饮粥二三碗。十余日，病不增减。药稍疏利，则委顿不堪。稍补助，则邪热愈炽。一日，因换床，即大汗口开，眼闭欲脱。用熟地一两二钱，附子四钱，浓朴二钱，合二陈汤如数，煎一大碗，黄昏时，服一半即熟睡。二更醒后，又服一半，也无感觉。子时后仍胡言乱语，天明则清醒。脉稍有神而加数，舌苔中心亦黄，（这是附子的缘故。）胸腹仍宽，能进粥食，于是用白虎汤加细生地等。连服数日，脉渐好，粥稍加。惟身热不退，夜间仍胡言乱语，左关脉独滞且沉。因思昼清夜昏，为热入血室。血室由厥阴所主，故左关独滞。仲景有刺期门之法，是邪结血分也，现在不明刺法，于是用归须、赤芍、新绛、青蒿、鳖甲、柴胡、黄芩、细生地之类。五六服，全然无效，此时已一月有二日矣。因病家笃信不获辞，彻夜思之，未得其理。忽记来复丹方中，有灵脂专入厥阴。暑湿浊邪，与伤寒不同，故前药不效。灵脂以浊攻浊，兼有硝、黄，直达至阴，助本元以祛邪，必当奏功。遂于前方去柴胡，送来复丹一钱，夜间即安睡，无胡言乱语。连进三服，身热即退。忽解小便甚长，色深碧稠如胶浆，病家惊询。章虚谷说：“此病根除矣。”因其少年多欲，湿之邪乘虚陷入肝肾，故与伤寒之热入血室，病同而邪不同，故药力不能胜邪则不效。此来复丹以浊攻浊，所以神效也。后进补药而愈。
Ren Shen Bai Hu Tang (Ginseng White Tiger Decoction) and Sheng Mai San (Generate the Pulse Powder) are essential formulas in the category of heatstroke treatment, both containing Ren Shen (Panax Ginseng Radix et Rhizoma). What is there to worry about? The patient did not believe this at all. Despite repeated explanations, he remained unconvinced. I wished to leave but was detained by heavy rain and forced to stay for lunch. I then said again, "Why not take the medicine as discussed now? If you feel uncomfortable, methods can be used to resolve it immediately." He reluctantly agreed and took the medicine, still anxious, fearing increased abdominal distension. Soon after, his condition became remarkably calm; after a long time, his mental clarity improved slightly, and he occasionally spoke one or two sentences. Only then did he stop doubting the use of Ren Shen. After ten days of regulation and treatment, he completely recovered.
Chen Ziping treated a patient who, in August, suffered from fever and delirium, with no appetite and constipation. All physicians considered it Shang Han (Cold Damage Disease). Initially, they used exterior-releasing methods, followed by purgative methods, but neither was effective. After more than fifty days, Ren Shen was administered, which slightly reduced the fever; however, when the dosage of Ren Shen was reduced, the fever returned. This led them to suspect deficiency even more strongly, so they used potent tonifying herbs, yet the lack of appetite and constipation persisted. Upon examination, the six pulses were harmonious, showing absolutely no signs of impending death. Chen stated that it is impossible for a Shang Han case to survive fifty days without eating or having a bowel movement. Knowing that the patient had been running around attending a funeral during the summer, he concluded that this was undoubtedly Zhong Shu (Heatstroke). The error lay in treating it as Shang Han and administering Ren Shen tonics; the heat pathogen, aided by the tonic, became entrenched, leading to this state. He prescribed Liu Yi San (Six-to-One Powder) mixed with cool water. The patient desired this, and taking more was not harmful. After ingestion, he slept immediately. Upon waking, he had a bowel movement, regained his appetite, and recovered within a few days.
Wu Qiao treated the wife of Wu Honglu, aged thirty. She was naturally obese and had eaten normally during the summer heat but failed to rise the next morning. Upon inspection, her eyes were closed, she was comatose, and her lips, tongue, and mouth were dark black. Phlegm rattled loudly like drumbeats, preventing even a spoonful of liquid from being swallowed; even medicines from the Qian Jin Fang (Prescriptions Worth a Thousand Gold) could not be administered. Wu Qiao was summoned. His six pulses were floating and soggy. He told Wu Honglu, "This is due to pre-existing wind-phlegm combined with heatstroke." He immediately administered Nong Po Xiang Ru Yin (Aucklandia and Mosla Decoction) and ground Niuhuang Wan (Calculus Bovis Pill) for instillation. The medicine went down, and the phlegm sound decreased. Further doses caused the black color to fade to dark brown. By dusk, her complexion resembled that of sheep liver; by the next morning, it was only slightly purple. Tonifying agents were then added. After five days, she opened her eyes and could speak. By the following day, she had largely recovered. (From *Tai Han Ji*.)
Zhang Xugu treated the wife of Zhou Xiaomei, who contracted summer-heat pathogen in June. She had a fever for five days before seeing Mr. Li. After one dose of dispersing herbs, her condition worsened the next day. A new physician, hearing of several days of constipation, prescribed Da Huang (Rhei Radix et Rhizoma) in large quantities, along with heavy doses of Xian Sheng Di Huang (Rehmanniae Radix Recens), Chai Hu (Bupleuri Radix), and Nong Po (Magnoliae Officinalis Cortex). Two bowel movements occurred, and the patient felt relieved. However, she experienced chills in the late afternoon, fever at dusk, which subsided at dawn, and insomnia throughout the night. Zhang examined her and asked about the cause. He explained: "Summer-heat is a combination of fire and dampness. Dampness is a yin pathogen that obstructs heat, preventing its release. Mr. Li’s use of dispersing herbs allowed the dampness to open and the heat to penetrate, which was not incorrect. However, the subsequent misuse of purgatives caused the pathogen to sink into the yin level, resulting in night fever without daytime fever, indicating a severe progression. Once the pathogen enters yin, returning it to yang is difficult. We must rotate the pivot mechanism and clear the heat from the yin level simultaneously." He used Cao Guo (Tsaoko Fructus), Cang Zhu (Atractylodis Rhizoma), and Nong Po to awaken the spleen, resolve dampness, and penetrate the membranous origin; Chai Hu to rotate the Shaoyin pivot; Qing Hao (Artemisiae Annuae Herba), Bie Jia (Testudinis Carapax et Plastrum), Zhi Mu (Anemarrhenae Rhizoma), and Huang Bo (Phellodendri Cortex) to clear heat from the yin level. After two days, there was no effect. The pulse was deficient and soft, thirst was intense with continuous tea drinking, abdominal fullness was present, and both urination and defecation were obstructed. She could not eat anything; even rice soup made her mouth sour. This indicated severe damage to the Middle Qi. Therefore, Zhi Mu was removed from the previous formula and Ren Shen was added. After another two days, urination improved slightly, but other symptoms persisted. The pulse remained soft and lacked spirit, and she continued to refuse food. It had been twelve days. Zhang warned that if this continued, the Stomach Qi would fail, and recovery would be impossible. Since both Spleen and Kidney were damaged, Yuan Qi (Original Qi) was powerless, and the San Jiao (Triple Burner) lost its qi transformation function, causing the pathogen to close inward. Kidney damage impaired opening and closing, leading to constipation; Spleen damage impaired transportation, leading to abdominal fullness. With Yang depleted, body fluids were not generated, causing severe thirst. Without Fu Zi (Aconiti Lateralis Radix Praeparata) and Gan Jiang (Zingiberis Rhizoma) to greatly assist Yang, the pathogen could not transform. Thus, Dang Shen (Codonopsis Radix), Cao Guo, Cang Zhu, Nong Po, Fu Zi, Gan Jiang, Sheng Jiang (Zingiberis Rhizoma Recens), Wu Mei (Mume Fructus), and Bai Shao (Paeoniae Radix Alba) were used, with a small amount of Huang Lian (Coptidis Rhizoma). After two days, abdominal fullness decreased, and loose stool like glue was passed. She began to consume thin porridge. After another two days, abdominal fullness resolved, porridge intake increased significantly, and urine volume increased. Nightly fever persisted, but chills ceased. This indicated the dampness had transformed, leaving only heat. Therefore, Fu Zi and Wu Mei were removed from the previous formula, and Zhi Mu (3 qian) and Sheng Shi Gao (Gypsum Fibrosum, 5 qian) were added. After two days, the fever completely subsided, and she recovered with clearing and tonifying regulation.
Li commented: After erroneous purgation in this case, heat left while dampness remained, merely injuring the Spleen and Stomach. Ultimately, the heat within the dampness was not fully eliminated. With Spleen and Stomach injured, and during the afternoon when Yang Qi declines, chills occurred. Heat trapped in dampness disturbed Ying Qi (Nutritive Qi), causing fever and insomnia. Damp-heat obstructed Qi mechanism, preventing fluid generation, causing thirst. At this stage, diuretic and bland herbs combined with aromatic spleen-awakening drugs should have been used for immediate cure. Instead, drying agents were used to forcibly drain, and cold herbs were added, further damaging the Spleen, hence ineffectiveness. Subsequently, strong acrid-dry herbs were used to forcibly drain; the Spleen Qi gained power from these herbs, and the dampness was entirely transformed by the rigid dryness. Thus, cold herbs were used to conclude the treatment. This was a series of errors masquerading as success and cannot serve as a standard. The inclusion of Wu Mei and Bai Shao in the formula was particularly meaningless. The physician claimed it was derived from Wumei Wan (Mume Pill), which is deceptive.
He from Xiaoshan felt unwell in summer, believing he had heatstroke. He ate one watermelon and took several doses of cooling herbs. Later, he had no other discomfort, only poor appetite. He forced himself to drink one or two bowls of thin porridge daily, finding it tasteless, yet he moved freely. Urine was pale yellow, stool was dry and infrequent, chest and abdomen were not distended, complexion was normal, and the tongue was bright red without coating, resembling Stomach Yin Deficiency. However, he disliked soups/liquids. The pulse was imperceptible at superficial and middle depths, but at the deep level (to the bone), it was thread-like and faint. Physicians still wanted to administer cooling herbs. He said: "This condition is neither evil fire nor Stomach Yin Deficiency, but severe depletion of Yuan Yang (Original Yang). Fortunately, urine is pale yellow and stool is firm, indicating solid Kidney Qi and root presence. Taking more cooling herbs will surely cause death." He used Fuzi Lizhong Tang (Aconite and Licorice Decoction for Regulating the Middle) minus Bai Zhu, plus Dang Gui (Angelicae Sinensis Radix) and Gui Zhi (Cinnamomi Ramulus) to nourish Ying. Several doses yielded no effect. Gui Zhi was removed, and Rou Gui (Cinnamomi Cortex), Wu Zhu Yu (Evodiae Fructus), and Huang Qi (Astragali Radix) were added. Over ten doses, there was no change. Another ten doses of the same formula also failed. Analyzing carefully: since urination was patent and stool was dry, Kidney Essence was not exhausted. Why did the Stomach remain closed? After stopping medication for four to five days, the situation remained the same. Thus, hot herbs were discarded. Heavy doses of Lu Jiao Jiao (Colla Cornus Cervi) were used, assisted by Gou Qi Zi (Lycii Fructus), Dang Gui, Ren Shen, Huang Qi, Rong Rui (Cynomorii Herba), and Guang Chen Pi (Citri Reticulatae Pericarpium) to moisten and nourish Yang. After ten doses, Lung pulse harmonized slightly, and diet increased marginally. After another ten doses, Stomach function opened, bowels moved, but the patient became weak and unable to sit up. After half a month of nourishment, he could get out of bed.
A man with a white face and robust build contracted heatstroke in summer. He recovered after two doses of cooling-resolving herbs because the pathogen was light. Ten days later, he was re-infected. He self-administered Su He Wan (Liquid Amber Pill), covered himself to induce sweating, causing massive loss of body fluids. Heat pathogen sank inward. Additionally, being young and prone to sexual excess, his pulse was empty, rapid, and rootless. Zhang said: "Su He Wan is acrid-warm and penetrating; it is suitable for cold but strictly contraindicated for summer-heat." Reluctantly, sweet-cool and bland herbs were given to nourish Yin and harmonize Yang. After four to five days, the pulse improved slightly, but the Chi position (Kidney area) was very empty. Fever persisted, with delirium at night and clarity at dawn. Tongue had a thin coating, pale yellow on edges, white and slippery in center. He drank two to three bowls of porridge daily. For over ten days, the condition did not improve or worsen. If herbs were too draining, he became exhausted; if tonified, heat intensified. One day, upon changing beds, he sweated profusely, mouth opened, and eyes seemed ready to protrude. Shu Di Huang (Rehmanniae Radix Preparata, 1 liang 2 qian), Fu Zi (4 qian), and Nong Po (2 qian) were combined with Er Chen Tang (Two-Cured Decoction) in appropriate amounts, decocted in a large bowl. Half was taken at dusk, leading to deep sleep. After waking at second watch, the remaining half was taken, with no adverse sensation. After midnight, delirium recurred, clearing at dawn. Pulse showed slight spirit but became faster. Tongue center coating turned yellow (due to Fu Zi). Chest and abdomen were comfortable, and he could eat porridge. Then, Bai Hu Tang (White Tiger Decoction) plus Xi Sheng Di Huang was used. After several days, pulse improved, and porridge intake increased. However, fever persisted, and night delirium continued. The Left Guan position (Liver/Gallbladder area) was specifically stagnant and deep. Zhang reasoned: Clarity by day and confusion by night indicates Heat Entering Blood Chamber (Xue Shi). The Blood Chamber is governed by Jueyin (Liver/Pericardium), hence the stagnation at Left Guan. Zhang Zhongjing prescribed puncturing Qimen (LR14) for such cases where pathogen binds in blood. Lacking acupuncture knowledge, Zhang used Gui Xu (Asari Radix et Rhizoma), Chi Shao (Paeoniae Radix Rubra), Xin Jiang (Safflower), Qing Hao, Bie Jia, Chai Hu, Huang Qin (Scutellariae Radix), and Xi Sheng Di Huang. Five to six doses were completely ineffective. It had been over a month. Due to the family's insistence, Zhang pondered overnight without solution. Suddenly remembering Laifu Dan (Reviving Life Pill) contains Ling Zhi (Pini Semen), which specifically enters Jueyin. Summer-damp turbid pathogen differs from Shang Han, explaining previous failure. Ling Zhi attacks turbidity with turbidity, combined with Xiao Ming Fen (Mirabilitum) and Da Huang, reaching the deepest Yin, assisting Original Qi to expel pathogen, promising efficacy. Thus, Chai Hu was removed from the previous formula, and 1 qian of Laifu Dan was sent. That night, he slept peacefully without delirium. After three consecutive doses, fever subsided. Suddenly, he passed a large volume of deep green, thick, glue-like urine. The family was alarmed. Zhang said: "The root of the disease is eradicated." Because of his youth and sexual excess, damp pathogen entered Liver and Kidney through deficiency. Thus, although the presentation resembled Shang Han's Heat Entering Blood Chamber, the pathogen was different, rendering previous drugs ineffective. Laifu Dan’s method of attacking turbidity with turbidity proved miraculous. He subsequently recovered with tonifying herbs.
