黄芩汤
黄芩（三钱） 甘草（二钱） 芍药（二钱） 大枣（三枚） 水煎服。按太少合病，少阳
经气郁而克戊土，故用甘草、大枣补其脾经，黄芩、芍药泄其相火，恐利亡脾阴，以致土燥而入阳明也。
猪苓汤
猪苓 苓茯 泽泻 滑石 阿胶（各一钱） 水二杯，煎一杯，去滓，入胶烊化，温服。
按土湿木郁，是生下热，故用二苓滑泽利水而泄湿，阿胶润木而清风也。
茵陈蒿汤
茵陈蒿（六钱） 栀子（五枚） 大黄（二钱） 水三杯，先煮茵陈至杯半，后入诸药
，煮至八分，温服，日三服，小盒饭利。按发黄乃湿热内郁，故用茵陈利水而除湿，栀子、大黄泄热而荡瘀也。

黄连清少阴之君火，黄柏、秦皮泄厥阴之湿热也。
伤寒病中，脉象滑利且出现四肢厥冷的，是里有热邪所致，用白虎汤主治。伤寒病中，脉象浮滑的，这是里有热邪、表有寒邪的表现，用白虎汤主治。三阳经合病时，出现腹部胀满、身体沉重、难以翻身转侧、口舌麻木不知五味且面色垢浊、说胡话（谵语）及小便失禁的症状。如果误用发汗法，会导致说胡话加重；如果误用泻下法，会导致额头出汗、手足逆冷；如果患者自汗出，则用白虎汤主治。伤寒病中，脉象浮、发热但无汗，且表证未解的，不可给予白虎汤；若口渴想喝水且没有表证的，用白虎加人参汤主治。伤寒病中，身体没有大热，但口燥渴、心烦、背部微微怕冷的，用白虎加人参汤主治。服用桂枝汤后，大汗出之后，出现极度烦渴不解、脉象洪大的，用白虎加人参汤主治。伤寒病经过吐法或下法治疗后，七八天病情仍未解除，热邪结聚在体内，表里都发热，时常怕风，极度口渴，舌面干燥且烦躁，想要喝几升水的，用白虎加人参汤主治。太阳经与少阳经合病，出现自发性腹泻的，用黄芩汤主治。阳明病中，若脉象浮、发热、口渴想喝水、小便不利的，用猪苓汤主治。阳明病中，出汗多且口渴的，不可用猪苓汤，因为汗多导致胃中干燥，猪苓汤会进一步利尿，从而加重津液亏损。
少阴病中，腹泻持续六七天，伴有咳嗽、呕吐、口渴、心烦无法入睡的，用猪苓汤主治。阳明病中，发热出汗的，这叫热邪向外发散，不会发生发黄病。但如果只有头部出汗，身上无汗，汗水仅到颈部即止，小便不利，口渴想喝浆水类的饮料，这是瘀热郁结在体内，身体一定会发黄，用茵陈蒿汤主治。伤寒病中，七八天后身体发黄如橘子色，小便不利、腹部轻微胀满的，用茵陈蒿汤主治。伤寒病中，身体发黄且发热的，用栀子柏皮汤主治。少阴病中，患病两三天以上，心中烦乱、无法躺卧睡眠的，用黄连阿胶汤主治。腹泻且想喝水的，是因为体内有热邪，用白头翁汤主治。热性腹泻且伴有肛门重坠感的，用白头翁汤主治。
根据以上各种证候，有的表现为大热，有的大渴，有的自汗，有的自发性腹泻，有的小便不利，有的烦躁不眠，有的瘀热发黄，有的挟热腹泻，总归都属于阳邪在体内所致，因此统称为里热证。

黄芩（三钱） 甘草（二钱） 芍药（二钱） 大枣（三枚） 用水煎服。按：太少合病（太阳与少阳合病），少阳经气郁结而克制脾胃（戊土），所以用甘草、大枣补益脾经，黄芩、芍药泄其相火，担心腹泻损伤脾阴，导致脾土干燥而转入阳明病。
猪苓汤
猪苓 茯苓 泽泻 滑石 阿胶（各一钱） 用水二杯，煎至一杯，去渣，加入阿胶使其溶化，温服。按：土湿木郁，是产生下焦湿热的原因，所以用猪苓、茯苓、滑石、泽泻利水而泄湿，阿胶润养肝木而清风热。

In Taiyang disease (Disease of the Taiyang channel), if the pulse is slippery and there is cold extremities (Jue, reversal cold), it indicates heat in the interior; Baihu Tang (White Tiger Decoction) is the primary treatment. In Taiyang disease, if the pulse is floating and slippery, this indicates heat in the interior and cold in the exterior; Baihu Tang (White Tiger Decoction) is the primary treatment. When the three Yang channels (Taiyang, Yangming, Shaoyang) are combined in disease, symptoms include abdominal fullness, heaviness of the body, difficulty in turning over, numbness of the mouth and face with a greasy appearance, delirium (Zhenyu), and urinary incontinence. If sweating methods are misused, delirium will worsen; if purgative methods are misused, sweat will appear on the forehead and cold extremities will occur; if spontaneous sweating is present, Baihu Tang (White Tiger Decoction) is the primary treatment. In Taiyang disease, if the pulse is floating, there is fever but no sweating, and the exterior syndrome is not resolved, Baihu Tang (White Tiger Decoction) should not be given; if there is thirst for water and no exterior syndrome, Baizhu Jia Renshen Tang (White Tiger Decoction plus Ginseng) is the primary treatment. In Taiyang disease, if there is no significant fever but there is dry mouth and thirst, mental restlessness, and slight aversion to cold on the back, Baizhu Jia Renshen Tang (White Tiger Decoction plus Ginseng) is the primary treatment. After taking Guizhi Tang (Cinnamon Twig Decoction), if profuse sweating occurs followed by severe, unrelenting thirst and a flooding pulse, Baizhu Jia Renshen Tang (White Tiger Decoction plus Ginseng) is the primary treatment. After emetic or purgative treatments for Taiyang disease, if the condition persists for seven to eight days with heat結 (juxtaposition) in the interior, simultaneous heat in the interior and exterior, occasional aversion to wind, extreme thirst, a dry tongue with irritability, and a desire to drink several liters of water, Baizhu Jia Renshen Tang (White Tiger Decoction plus Ginseng) is the primary treatment. When Taiyang and Shaoyang channels are combined in disease, with spontaneous diarrhea, Huangqin Tang (Scutellaria Decoction) is administered. In Yangming disease, if the pulse is floating, there is fever, thirst for water, and difficult urination, Zhuling Tang (Polyporus Decoction) is the primary treatment. In Yangming disease, if there is excessive sweating and thirst, Zhuling Tang (Polyporus Decoction) should not be used, because excessive sweating causes dryness in the stomach, and Zhuling Tang (Polyporus Decoction) promotes urination, which would further deplete fluids.
In Shaoyin disease, if diarrhea lasts for six to seven days accompanied by cough, vomiting, thirst, mental restlessness, and inability to sleep, Zhuling Tang (Polyporus Decoction) is the primary treatment. In Yangming disease, if there is fever and sweating, this is called "heat venting" (Re Yue), meaning heat is dispersing outward, so jaundice will not develop. However, if there is only sweating on the head, no sweating on the body, stopping at the neck, difficult urination, and thirst for liquid food, this indicates stagnant heat in the interior, and jaundice will certainly develop; Yinchen Hao Tang (Artemisiae Scopariae Decoction) is the primary treatment. In Taiyang disease, if after seven to eight days the body turns yellow like an orange peel, with difficult urination and mild abdominal fullness, Yinchen Hao Tang (Artemisiae Scopariae Decoction) is the primary treatment. In Taiyang disease, if there is jaundice with fever, Zhizi Bopi Tang (Gardeniae and Phellodendron Bark Decoction) is the primary treatment. In Shaoyin disease, if two to three days have passed since onset, with mental restlessness and inability to lie down and sleep, Huanglian Ejiao Tang (Coptis and Donkey-Hide Gelatin Decoction) is the primary treatment. If there is diarrhea with a desire to drink water, it is due to internal heat; Baitouweng Tang (Pulsatilla Decoction) is the primary treatment. For hot diarrhea with a sensation of rectal tenesmus (Zhongzhong), Baitouweng Tang (Pulsatilla Decoction) is the primary treatment.
According to the above syndromes, whether presenting as high fever, extreme thirst, spontaneous sweating, spontaneous diarrhea, difficult urination, irritability and insomnia, stagnant heat causing jaundice, or heat-complicated diarrhea, they all belong to pathogenic Yang factors residing in the interior; thus, they are collectively categorized as Interior Heat Syndromes.
Baihu Tang (White Tiger Decoction)
Zhimu (Anemarrhenae Rhizoma, 3 qian) Shigao (Gypsum Fibrosum, 8 qian) Gancao (Glycyrrhizae Radix et Rhizoma, 1 qian, honey-fried) Jingmi (Oryza Sativa, 4 qian). Use two cups of water, boil until the rice is cooked and the decoction is ready, yielding approximately one cup. Take warm. Commentary: The Baihu syndrome is caused by internal stagnation of dry-heat. Therefore, Shigao (Gypsum Fibrosum) clears Lung Metal to reduce fever, Zhimu (Anemarrhenae Rhizoma) moistens dryness and drains fire, while Gancao (Glycyrrhizae Radix et Rhizoma) and Jingmi (Oryza Sativa) tonify the Middle Jiao, transform Qi, generate fluids, and relieve thirst.
Baizhu Jia Renshen Tang (White Tiger Decoction plus Ginseng)
Zhimu (Anemarrhenae Rhizoma, 3 qian) Shigao (Gypsum Fibrosum, 8 qian) Gancao (Glycyrrhizae Radix et Rhizoma, 1 qian, honey-fried) Jingmi (Oryza Sativa, 4 qian) Renshen (Panacis Ginseng Radix, 1.5 qian). Decoct in water and take. Commentary: Adding Renshen (Panacis Ginseng Radix) to Baihu Tang clears Lung Metal, benefits Qi, generates fluids, and transforms water; it is a miraculous formula for relieving thirst after sweating.
Huangqin Tang (Scutellaria Decoction)
Huangqin (Scutellariae Radix, 3 qian) Gancao (Glycyrrhizae Radix et Rhizoma, 2 qian) Shaoyao (Paeoniae Radix Alba, 2 qian) Dazao (Jujubae Fructus, 3 pieces). Decoct in water and take. Commentary: In the combination of Taiyang and Shaoyang diseases, the Qi of the Shaoyang channel stagnates and attacks the Spleen/Stomach (Wu Earth). Therefore, Gancao (Glycyrrhizae Radix et Rhizoma) and Dazao (Jujubae Fructus) are used to tonify the Spleen channel, while Huangqin (Scutellariae Radix) and Shaoyao (Paeoniae Radix Alba) drain Ministerial Fire. This prevents the loss of Spleen Yin due to diarrhea, which could lead to dryness of Earth and transmission to the Yangming channel.
Zhuling Tang (Polyporus Decoction)
Zhuling (Polypori Sclerotium, 1 qian) Fuling (Poria, 1 qian) Zexie (Alismatis Rhizoma, 1 qian) Huashi (Talcum, 1 qian) Ejiao (Asini Corii Colla, 1 qian). Use two cups of water, decoct to one cup, strain, add Ejiao (Asini Corii Colla) and melt it. Take warm. Commentary: Dampness in Earth and stagnation of Wood generate lower-heat. Therefore, Zhuling (Polypori Sclerotium), Fuling (Poria), Huashi (Talcum), and Zexie (Alismatis Rhizoma) are used to promote urination and drain dampness, while Ejiao (Asini Corii Colla) nourishes Liver Wood and clears wind-heat.
Yinchen Hao Tang (Artemisiae Scopariae Decoction)
Yinchen Hao (Artemisiae Scopariae Herba, 6 qian) Zhizi (Gardeniae Fructus, 5 pieces) Dahuang (Rhei Radix et Rhizoma, 2 qian). Use three cups of water, first decoct Yinchen Hao (Artemisiae Scopariae Herba) until half a cup remains, then add other herbs, decoct to 0.8 cup. Take warm, three times a day. Cure when urine flows freely. Commentary: Jaundice is caused by internal stagnation of damp-heat. Therefore, Yinchen Hao (Artemisiae Scopariae Herba) promotes urination to remove dampness, while Zhizi (Gardeniae Fructus) and Dahuang (Rhei Radix et Rhizoma) drain heat and purge stagnant heat.
Zhizi Bopi Tang (Gardeniae and Phellodendron Bark Decoction)
Zhizi (Gardeniae Fructus, 6-7 pieces) Huangbapi (Phellodendri Cortex, 2 qian) Gancao (Glycyrrhizae Radix et Rhizoma, 1 qian). Decoct in water and take. Commentary: Body jaundice with fever is originally caused by stagnant heat. Therefore, Gancao (Glycyrrhizae Radix et Rhizoma) is used to cultivate Earth and tonify the Middle, while Zhizi (Gardeniae Fructus) and Huangbapi (Phellodendri Cortex) drain dampness and clear stagnant heat.
Huanglian Ejiao Tang (Coptis and Donkey-Hide Gelatin Decoction)
Huanglian (Coptidis Rhizoma, 2 qian) Huangqin (Scutellariae Radix, 0.5 qian) Shaoyao (Paeoniae Radix Alba, 1 qian) Ejiao (Asini Corii Colla, 1.5 qian) Jizihuang (Galli Ovum Vitellus, 1 piece). Use one and a half cups of water, decoct to 0.8 cup, strain, add Ejiao (Asini Corii Colla) completely, cool slightly, add Jizihuang (Galli Ovum Vitellus), mix well, and take warm. Commentary: Dry Earth conquers Water and scorches Heart fluids. Fluid depletion and Water exhaustion cause Essence to fail to store Spirit. Therefore, Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), and Shaoyao (Paeoniae Radix Alba) are used to clear Sovereign Fire and relieve irritability and heat, while Ejiao (Asini Corii Colla) and Jizihuang (Galli Ovum Vitellus) tonify Spleen Essence and nourish Dry Earth.
Baitouweng Tang (Pulsatilla Decoction)
Baitouweng (Pulsatillae Radix, 1 qian) Huanglian (Coptidis Rhizoma, 1.5 qian) Huangbai (Phellodendri Cortex, 1.5 qian) Qinpi (Fraxini Cortex, 1.5 qian). Decoct in water and take. If not cured, prepare another dose. Commentary: In Jueyin disease, the recovery of Yang generates internal heat. Therefore, Baitouweng (Pulsatillae Radix) clears Ministerial Fire of Shaoyang, Huanglian (Coptidis Rhizoma) clears Sovereign Fire of Shaoyin, and Huangbai (Phellodendri Cortex) and Qinpi (Fraxini Cortex) drain damp-heat of Jueyin.
