（出自《肘后备急方》）治疗时行瘟疫发病一两天，出现头痛和高热。
麻黄（四两） 桂心 甘草（炙） 白芍（二两） 大黄 黄芩（三两）。麻黄能开通腠理并发汗，桂心能引导血液化为汗液，黄芩用来清泄上焦和中焦的热邪，大黄用来泻下中焦和下焦的热邪，甘草和白芍，能够缓解时行瘟疫的郁热从内向外透发的病机，这与伤寒病邪由表传里的情况不同。因此，虽然病程仅一两天，病情尚浅，但治疗方法应绝对不同于伤寒。（郁热终究以向外透解为易，大黄应当减量使用。）
治疗时气、瘴气、黄疸、疟疾、赤白痢等证候。
茵陈 栀子 鳖甲（炙） 芒硝（二两） 大黄（五两） 常山 杏仁（炒，三两） 巴豆（一两，去心）。服用一丸。若无效，则加用栀子和淡豆豉，即栀豉汤。合用常山可以涌吐，合用杏仁可以解肌。大黄和芒硝，即承气汤之意，可以荡涤热邪。
（出自张景岳）治疗风湿发黄，发热身痛，脉紧，表里同病，小便不利，中寒泄泻等证候。
柴胡（二三钱） 茯苓 猪苓 泽泻（一钱） 白术（二三钱） 肉桂（一二钱）。用水一盏半，煎服。
（出自张仲景）治疗伤寒少阴证，阳邪入里，四肢厥冷不温。（热结于体内。）或者咳嗽，（气逆挟痰。）或者心悸，（挟饮邪）或者小便不利，或者腹中痛，或者泄利伴有肛门重坠感。（皆因热结于体内所致。伤寒邪气在三阳经，则手足必然发热。到了太阴经，则手足温暖。到了少阳经，则热邪逐渐深入，四肢逆冷而不温。到了厥阴经，则手足逆冷。医经说：热邪越深，厥冷也越深；热邪越微，厥冷也越微。此汤剂用于消散传入之经的热邪。）
柴胡 芍药 枳实 甘草，等分为末。用水调服。咳嗽者加五味子，（收敛逆气。）干姜（散肺寒。）并加茯苓。
医经说：凡是四肢厥逆者不可用下法，故用枳实泄除结热，甘草调理逆气，柴胡疏散阳邪，芍药收敛元阴。以辛味和苦味……
(From *Zhouhou Beiji Fang*) Treats epidemic febrile diseases occurring one or two days after onset, characterized by headache and high fever.
Mahuang (Ephedrae Herba) (4 liang), Guixin (Cinnamomi Cortex), Zhigancao (Glycyrrhizae Radix et Rhizoma Preparata), Shaoyao (Paeoniae Radix Alba) (2 liang), Dahuang (Rhei Radix et Rhizoma), Huangqin (Scutellariae Radix). Mahuang can open the couli (pores) and induce sweating; Guixin can guide blood to transform into sweat; Huangqin clears heat in the upper and middle jiao; Dahuang purges heat in the middle and lower jiao; Zhigancao and Shaoyao can address the pathogenesis of epidemic plague where stagnant heat manifests from interior to exterior, which differs from Shanghan (Cold Damage) where pathogens transmit from exterior to interior. Therefore, although the disease duration is only one or two days and the condition is superficial, the treatment method must be absolutely different from that of Shanghan. (Stagnant heat is ultimately easier to resolve via exterior release; Dahuang should be used in reduced dosage.)
Treats conditions such as Shiqi (seasonal qi pathogens), Zhangqi (miasma qi), Huangbing (jaundice), Nuojie (malaria), and Chi Bai Li (dysentery with red and white discharge).
Yinchen (Artemisiae Scopariae Herba), Zhizi (Gardeniae Fructus), Biejia (Testudinis Carapax et Plastrum Preparated), Mangxiao (Natrii Sulfas) (2 liang), Dahuang (Rhei Radix et Rhizoma) (5 liang), Changshan ( Dichroae Radix), Xingren (Pruni Semen Preparatum) (stir-fried, 3 liang), Badou (Crotonis Fructus) (1 liang, heart removed). Take one pill. If ineffective, add Zhizi and Danshi (Gardeniae Fructus and Soyaensis Semen Preparatum), forming Zhichi Tang (Gardenia and Fermented Soybean Decoction). Combined with Changshan, it can induce vomiting; combined with Xingren, it can release the muscle layer. Dahuang and Mangxiao constitute the principle of Chengqi Tang (Harmonizing the Qi Decoction), capable of sweeping away heat pathogens.
(From Zhang Jingyue) Treats Fengshi Huangbin (wind-damp jaundice), fever and body pain, tight pulse, simultaneous involvement of exterior and interior, difficult urination, and cold-induced diarrhea.
Chaihu (Bupleuri Radix) (2-3 qian), Fuling (Poria), Zhuling (Polyporus), Zexie (Alismatis Rhizoma) (1 qian), Baizhu (Atractylodis Macrocephalae Rhizoma) (2-3 qian), Rougui (Cinnamomi Cortex) (1-2 qian). Decoct in 1.5 bowls of water and take orally.
(From Zhang Zhongjing) Treats Shaoyin syndrome of Shanghan, where yang pathogens enter the interior, causing four-ni (cold extremities) without warmth. (Heat binds in the interior.) Or cough, (qi rebellion with phlegm.) Or palpitations, (with fluid retention.) Or difficult urination, Or abdominal pain, Or diarrhea with a sensation of heaviness in the anus. (All caused by heat binding in the interior. When Shanghan pathogens are in the Taiyang, Yangming, and Shaoyang meridians, hands and feet are necessarily hot. Upon reaching the Taiyin meridian, hands and feet become warm. Upon reaching the Shaoyang meridian, heat pathogens deepen, and limbs become cold and unwarmed. Upon reaching the Jueyin meridian, hands and feet become cold. The Classics state: "The deeper the heat, the deeper the coldness; the slighter the heat, the slighter the coldness." This decoction is used to dissipate heat transmitted through the meridians.)
Chaihu (Bupleuri Radix), Shaoyao (Paeoniae Radix), Zhishi (Aurantii Fructus Immaturus), Gancao (Glycyrrhizae Radix et Rhizoma), ground equally into powder. Mix with water and drink. For cough, add Wuweizi (Schisandrae Fructus) (to restrain rebellious qi) and Ganjiang (Zingiberis Rhizoma) (to disperse lung cold), along with Fuling (Poria).
The Classics state: "For all cases of four-ni (cold extremities), purgation is contraindicated." Therefore, Zhishi is used to drain bound heat, Gancao regulates rebellious qi, Chaihu disperses yang pathogens, and Shaoyao conserves primordial yin. Using bitter and pungent flavors...
