阳明病，未经过催吐或泻下治疗，却出现心烦症状的：
大黄（四两，去皮，用清酒浸泡，味苦性寒） 甘草（二两，蜜炙，味甘性平） 芒硝（半升，味咸性大寒）
以上三味药，切碎，用水三升，煎煮至剩余一升，滤去药渣，加入芒硝，再次置于火上微火煮沸，少量多次温服。
成无己说：热邪弥漫于体内，应用咸寒之品治疗，辅以苦甘之品。芒硝味咸性寒以清除热邪，大黄味苦性寒以荡涤实邪，甘草味甘性平，辅助这两味药推陈出新。
阳明病，脉象迟缓，出汗，不恶寒，身体沉重，呼吸短促，腹部胀满，定时发热，大便干硬的：
大黄（四两，酒洗，味苦性寒） 厚朴（半斤，炙制，去皮，味苦性温） 枳实（五枚，炙制，味苦性寒） 芒硝（三合，味咸性寒）
以上四味药，用水一斗，先煮厚朴和枳实，取汁五升，滤去药渣，加入大黄，再煎煮至剩余二升，滤去药渣，加入芒硝，再次置于微火上煮一两沸，分两次温服。
成无己说：《内经》说：燥邪胜复，应用苦味攻下之法。大黄、枳实的苦味可以润燥除热。又说：燥邪内侵，应用苦温之法。厚朴的苦味……
这就是大承气汤去掉芒硝，减少厚朴（六两）、枳实（二枚）。大热结实者给予大承气汤；小热微结者给予承气汤。因为热势不是特别严重，所以去掉芒硝；又因为结滞不至于坚硬，所以减少厚朴和枳实。又名顺气汤，又名三物厚朴汤。成无己说：承，意为顺承。伤寒传入胃中，胃气郁滞，糟粕秘结，壅塞而成实证，这是正气不能舒顺。此汤能荡涤实邪，使正气得以顺承，故名为承气汤。他又说：承气汤属于下药，使用尤其应当审慎。确知有大实、大满、坚且有燥屎时，才可投用。如果虽有寒热但病邪未除，况且没有满实症状而妄加投用，就会产生结胸、痞气等疾病。所以说，伤寒有使用承气汤的禁忌。
据海藏（张元素）云：调胃承气汤治疗实证而无胀满，即正阳阳明证；大承气汤治疗大满大实，即太阳阳明证；小承气汤……药物则……损伤……承气……
Yangming disease, where there is mental restlessness (Xin Fan) without prior emesis or purgation:
Rhubarb Radix et Rhizoma (Da Huang, 4 liang, peeled, soaked in clear wine, bitter and cold) Licorice Root (Gan Cao, 2 liang, honey-fried, sweet and neutral) Mirabilite (Mang Xiao, half sheng, salty and very cold)
Take the above three herbs, cut into pieces, decoct with three sheng of water to obtain one sheng, strain off the dregs, add Mang Xiao, heat again over a mild fire until boiling, and take warm in small amounts frequently.
Cheng Wuji stated: When heat pervades internally, treat with salty-cold substances, assisted by bitter-sweet ones. Mang Xiao is salty and cold to eliminate heat; Da Huang is bitter and cold to purge accumulation; Gan Cao is sweet and neutral, assisting these two substances to push out the old and bring forth the new.
Yangming disease characterized by a slow pulse, sweating, aversion to cold absent, heavy body, shortness of breath, abdominal fullness, tidal fever, and hard stool:
Rhubarb Radix et Rhizoma (Da Huang, 4 liang, washed with wine, bitter and cold) Magnolia Bark (Hou Po, half jin, fried, peeled, bitter and warm) Immature Bitter Orange (Zhi Shi, five pieces, fried, bitter and cold) Mirabilite (Mang Xiao, three he, salty and cold)
Take the above four herbs, decoct with one dou of water. First decoct Hou Po and Zhi Shi to obtain five sheng, strain off the dregs, add Da Huang, decoct further to obtain two sheng, strain off the dregs, add Mang Xiao, heat briefly over a mild fire for one or two boils, and divide into two doses to be taken warm.
Cheng Wuji stated: The *Neijing* says: When dryness prevails, use bitter purgatives. The bitterness of Da Huang and Zhi Shi moistens dryness and eliminates heat. It also states: When dryness invades internally, treat with bitter-warm methods. The bitterness of Hou Po...
This refers to Da Cheng Qi Tang minus Mang Xiao, with reduced Hou Po (6 liang) and Zhi Shi (two pieces). For cases of severe heat and solid accumulation, administer Da Cheng Qi Tang; for cases of slight heat and minor accumulation, administer Cheng Qi Tang. Because the heat is not extreme, Mang Xiao is omitted; because the accumulation is not hard, Hou Po and Zhi Shi are reduced. Also known as Shun Qi Tang or San Wu Hou Po Tang. Cheng Wuji stated: "Cheng" means to follow or accommodate. When Shaoyang pathogen enters the stomach, stomach qi becomes stagnant, waste products become constipated, obstructing and forming excess syndrome, preventing the healthy qi from flowing smoothly. This decoction purges excess pathogens, allowing the healthy qi to flow smoothly, hence named Cheng Qi Tang. He further stated: Cheng Qi Tang belongs to purgative formulas; their use requires particular caution. Only when there is confirmed great excess, great fullness, hardness, and dry feces should they be administered. If one administers them recklessly in cases where chills and fever persist but there is no fullness or excess, conditions such as Jie Xiong (Chest Binding) and Pi Qi (Pi Syndrome) may arise. Thus, it is said that there are warnings regarding the use of Cheng Qi Tang in Shaoyang diseases.
According to Haicang (Zhang Yuansu): Tiao Wei Cheng Qi Tang treats excess without fullness, corresponding to Zheng Yang Yangming syndrome; Da Cheng Qi Tang treats great fullness and great excess, corresponding to Tai Yang Yangming syndrome; Xiao Cheng Qi Tang... regarding the herbs... damage...
