This formula is also known as Fumai Tang (Pulse Restoring Decoction). It is indicated for Jiedai Mai (intermittent and irregular pulse) and Xindongji (palpitations with a sensation of heart movement). This decoction employs moistening and yin-nourishing herbs to rescue dryness and depletion, thereby restoring the jiedai pulse to a state of harmony; hence it is named Fumai Tang.

If after taking Guizhi Tang (Cinnamon Twig Decoction) there is profuse sweating and a surging pulse, administer Guizhi Tang again. If the condition resembles malaria, occurring twice daily, resolution will follow sweating. If the pulse remains surging after sweating, the pathogen persists. In cases resembling malaria with two daily episodes, the pathogen resides between Ying (Nutritive) and Wei (Defensive) levels; administer Guizhi Er Mahuang Yi Tang (Two Parts Cinnamon Twig to One Part Ephedra Decoction) to disperse pathogens in Ying and Wei. The dosage of Guizhi Tang ingredients is double that of Mahuang Tang (Ephedra Decoction) because the injury to Wei is greater than to Ying. The previously mentioned Guizhi Mahuang Ban Tang (Half Cinnamon Twig and Half Ephedra Decoction) was used due to the absence of sweating; now that profuse sweating has occurred, Guizhi is doubled relative to Mahuang.

In Yangming Disease (disease of the Yangming channel/organ system), presenting with Chaore (tidal fever) and Chenyu (delirious speech), abdominal fullness, panting, and Ji ran han chu (continuous sweating on hands and feet), indicating hardened stool, this formula is indicated: Da Chengqi Tang (Major Order the Qi Decoction). Chaore indicates Yangming Neishi (interior excess in Yangming); Chenyu, panting, and fullness indicate heat accumulation in the Stomach; hand and foot sweating confirms hardened stool, which requires Da Chengqi Tang. "Cheng" means to follow or smooth. The Stomach is the sea of water and grain; when pathogens enter, causing Qi stagnation and fecal impaction, purgation is necessary to restore the smooth flow of Zhengqi (Upright Qi), hence the name "Chengqi". Wang Bing stated: Purgation requires bitter herbs. Zhishi (Aurantium Fructus), bitter and neutral, serves as Jun (Chief) herb to break hardness and resolve accumulation. Houpo (Magnolia Bark), bitter and warm, serves as Chen (Deputy) herb to move Qi and relieve fullness. For heat rampant internally, salty-cold herbs are used; Mangxiao (Natrii Sulfas) serves as Zuo (Assistant) herb to clear heat and soften hardness. For dryness prevailing, bitter herbs are used to purge; Dahuang (Rhei Radix et Rhizoma) serves as Shi (Envoy) herb to purge and moisten dryness. Wang Haicang said: Houpo removes obstruction, Zhishi relieves fullness, Mangxiao softens hardness, and Dahuang purges excess. Only when all four symptoms—Pi (obstruction), Man (fullness), Zao (dryness), and Shi (excess)—are present should this formula be used. Misusing purgation when inappropriate leads to countless complications. Note: There are three types of Chengqi formulas; selection must be precise. Da Chengqi Tang is for true severe heat and excess; Xiao Chengqi Tang (Minor Order the Qi Decoction) for mild heat and excess; Tiaowei Chengqi Tang (Regulate the Stomach Order the Qi Decoction) for heat binding without fullness or hardness. This is the appropriate method. Using Xiao Chengqi Tang for severe disease fails to subdue pathogens; using Da Chengqi Tang for mild disease injures Zhengqi. Zhang Zhongjing stated: Before administering Da Chengqi Tang, first give Xiao Chengqi Tang. If Zhuan shiqi (passing gas) occurs, dry feces are present, and Da Chengqi Tang may be given. If no Zhuan shiqi occurs, do not purge, as it will cause fullness and difficult treatment. Furthermore, once purgation occurs with Chengqi formulas, do not administer again. How earnest and cautious is this advice.
