阳明病，脉象迟缓，虽然出汗但不怕冷，身体必定沉重，呼吸短促，腹部胀满且气喘，伴有定时发热（潮热），这说明表证即将解除，可以攻逐里实。如果手足濈然汗出，说明大便已经坚硬，应当用大承气汤主治。如果出汗多，仅有轻微发热和怕冷，说明表证尚未解除；如果发热没有定时（不潮），不可给予承气汤。如果腹部显著胀满且不通畅，可以给予小承气汤，轻微调和胃气，不要导致剧烈泻下。
阳明病出现脉迟，是湿气旺盛的征象。虽然出汗但不怕冷，说明表证已解，但因为体内土湿阻滞，里热尚未完全形成。因此身体感到沉重、浑浊濡滞。等到胃中热气盛大，燥热夺取了湿气，导致脏腑壅塞遏阻，出现呼吸短促、腹部胀满且气喘，伴有定时发热（潮热），这说明外证欲解，可以攻逐里实。再验证其手足濈然汗出，这是胃热盛实、大便已经坚硬的标志，适宜用大承气汤泄热通便。因为四肢的气血禀受于胃，胃寒则四肢厥冷，胃热则四肢气蒸而汗泄，所以手足汗出是胃热极大、大便坚硬的指征。如果出汗虽多，但仍轻微发热且怕冷，说明表邪未解，不可攻逐里实。即使表证已解，但如果发热没有定时，尚非可下的时机，不可给予承气汤。如果腹部显著胀满不通，病情紧急不能等待，可以给予小承气汤，轻微调和胃气，通导显著胀满即可停止，不要导致剧烈泻下。
大黄（四两），浓朴（二两），枳实（二枚，煮）。以上三味药，用水四升，煮取一升二合，去渣，分三次温服。初次服药后，如果大便通畅（更衣），就停止服用剩下的药；如果没有排便，则喝完剩余的汤药；如果排了便，就不要再服用。
太阳病，如果用吐法、下法或发汗法治疗后，出现轻微心烦，小便频数，大便因此变硬，应给予小承气汤调和，即可痊愈。吐、下、发汗损伤了津液，微微感觉心烦，小便次数增多，大便因此变硬，这是将来可能发展为的大承气汤证，宜尽早用小承气汤调和，即可痊愈。
阳明病，未经过吐法或下法治疗，却出现心烦，可以给予调胃承气汤。不因吐下而心烦，是因为胃阳原本旺盛，称为“正阳阳明”。燥热的脾土耗伤津液则产生烦闷，心烦即是谵语（胡言乱语）的根源，严重时会出现谵语，这也是大承气汤证的初期表现。
Yangming disease, with a slow pulse, sweating without aversion to cold, necessarily presents with heaviness of the body, shortness of breath, abdominal fullness and wheezing. If there is tidal fever (Chao Re), it indicates that the exterior syndrome is about to resolve and interior excess can be purged. If there is continuous sweating on the hands and feet (Shou Zu Ji Ran Han Chu), this signifies that the feces have become hard; Da Cheng Qi Tang (Great Order the Qi Decoction) should be primarily administered. If there is profuse sweating with only slight fever and aversion to cold, the exterior has not yet resolved. If the fever is not tidal, Cheng Qi Tang should not be given. If there is significant abdominal fullness and obstruction, Xiao Cheng Qi Tang (Minor Order the Qi Decoction) may be given to slightly harmonize the Stomach Qi, avoiding severe purgation.
In Yangming disease, a slow pulse indicates abundant dampness. Although sweating occurs without aversion to cold, indicating the resolution of the exterior syndrome, the interior heat has not fully formed due to Earth-dampness stagnation. Consequently, the body feels heavy and turbidly stagnant. Only when Stomach heat becomes excessive, with dryness overcoming dampness and causing congestion and obstruction in the Zang-Fu organs, does one observe shortness of breath, abdominal fullness, wheezing, and tidal fever. This indicates that the exterior symptoms are resolving and interior excess can be purged. Verifying continuous sweating on the hands and feet confirms that Stomach heat is exuberant and real, and the feces are hard; thus, Da Cheng Qi Tang (Great Order the Qi Decoction) is suitable for draining heat and unblocking bowels. The limbs derive their Qi from the Stomach; Stomach cold causes cold extremities, while Stomach heat causes Qi evaporation and sweating. Therefore, sweating on the hands and feet is a sign of extreme Stomach heat and hard feces. If sweating is profuse but accompanied by slight fever and aversion to cold, the exterior remains unresolved, and interior purging is contraindicated. Even if the exterior has resolved, if the fever is not tidal, it is not yet time for purgation, and Cheng Qi Tang should not be given. If there is significant abdominal fullness and obstruction, the condition is urgent and cannot wait; Xiao Cheng Qi Tang (Minor Order the Qi Decoction) may be given to slightly harmonize Stomach Qi and relieve significant fullness, stopping before severe purgation occurs.
Da Huang (Rhubarb Root and Rhizome, 4 liang), Hou Po (Magnolia Bark, 2 liang), Zhi Shi (Immature Bitter Orange, 2 pieces, boiled). These three ingredients are decocted in 4 sheng of water until 1.2 sheng remains. The dregs are removed, and the liquid is divided into three warm doses. After the first dose, if bowel movement occurs (Geng Yi), stop taking the remaining medicine. If no bowel movement occurs, consume the entire dose. If bowel movement occurs after consuming the full dose, do not take further medicine.
In Taiyang disease, if vomiting, purgation, or sweating therapy results in slight irritability, frequent urination, and consequently hard feces, Xiao Cheng Qi Tang (Minor Order the Qi Decoction) should be given to harmonize, leading to recovery. Vomiting, purgation, and sweating damage Body Fluids, causing slight irritability and increased urinary frequency, which leads to hard feces. This represents a potential future Cheng Qi Tang pattern; early administration of Xiao Cheng Qi Tang (Minor Order the Qi Decoction) to harmonize will lead to recovery.
In Yangming disease, if irritability occurs without prior vomiting or purgation, Tiao Wei Cheng Qi Tang (Regulate the Stomach Order the Qi Decoction) may be given. Irritability not caused by vomiting or purgation indicates originally vigorous Stomach Yang, known as "Zheng Yang Yangming" (True Yang Yangming). Dry-heat in the Spleen/Earth consumes Body Fluids, causing irritability. Irritability is the root of delirium (Zhan Yu); in severe cases, delirium ensues. This is also an initial stage of the Da Cheng Qi Tang pattern.
