This is the Da Cheng Qi Tang (Great Order the Yang Decoction) with Mang Xiao (Natrii Sulfas) removed and Tao Ren (Prunus Persica Seed) added. This formula removes Zhi Shi (Aurantii Fructus Immaturus) and Hou Po (Magnoliae Officinalis Cortex), adds Gui Zhi (Cinnamomi Ramulus) and Tao Ren, and treats Taiyang disease (Taiyang syndrome) where heat-toxin has entered the meridians and condensed in the five zang organs, causing hematemesis (vomiting blood) and hematochezia (bleeding from the anus). It also treats heat condensation in the Bladder, presenting with mental restlessness resembling madness, resolution of exterior symptoms, but urgency and pain in the lower abdomen. Additionally, it addresses bloody dysentery, robust constitution, trauma injuries resulting in blood stasis and pain, and other such conditions.

This is the Da Cheng Qi Tang with Gan Cao (Glycyrrhizae Radix et Rhizoma) added. It treats abdominal fullness and solid pain characteristic of the Da Cheng Qi Tang syndrome; it also treats internal heat and constipation characteristic of the Xiao Cheng Qi Tang (Minor Order the Yang Decoction) syndrome; and it treats delirium and diarrhea characteristic of the Tiao Wei Cheng Qi Tang (Regulate the Stomach and Order the Yang Decoction) syndrome. This decoction combines these three indications into one, hence the name San Yi Cheng Qi Tang (Three-in-One Order the Yang Decoction).

This is the Da Cheng Qi Tang with Gan Cao, Huang Qin (Scutellariae Radix), Shao Yao (Paeoniae Radix Alba), and Chai Hu (Bupleuri Radix) added, intended to replace Da Cheng Qi Tang, Xiao Cheng Qi Tang, Tiao Wei Cheng Qi Tang, San Yi Cheng Qi Tang, and Da Xian Xiong Tang (Major Chest-Draining Decoction). Hence it is named Liu Yi Shun Qi Tang (Six-in-One Smooth Qi Decoction). "Shun" (Smooth/Compliant) implies "Cheng" (Order/Receive).

This is the Da Cheng Qi Tang with Gan Cao, Ren Shen (Ginseng Radix), and Dang Gui (Angelicae Sinensis Radix) added. It treats hardness and pain in the epigastrium, purgation of pure clear water, delirium, thirst, and fever. Quack doctors mistakenly identify this as a leakage syndrome and use hot herbs to stop the diarrhea, which is an error. This condition arises because heat pathogen has transmitted inward, creating dry feces in the stomach, termed "heat-binding diarrhea," commonly known as "paradoxical diarrhea."

This is the Da Cheng Qi Tang with Mang Xiao removed and Qiang Huo (Notopterygii Rhizoma et Radix) added. It treats wind-stroke presenting with obstruction of urination and defecation and internal excess of pathogenic factors. Upper jiao (Upper Burner) fullness is treated with Hou Po; middle jiao fullness is broken down by Zhi Shi; lower jiao excess is evacuated by Da Huang (Rhei Radix et Rhizoma). Qiang Huo is included because the treatment must address the wind pathogen. After administration, urination and defecation slightly flow, restoring qi transformation in the three jiao; thus it is called "San Hua" (Three Transformations).

This is the Da Cheng Qi Tang with Mang Xiao removed, adding Ma Ren (Semen Cannabis), Shao Yao, and Xing Ren (Armeniacae Semen Amarum), processed into honey pills. Also known as Pi Yue Wan (Spleen-Restriction Pill) or Run Chang Wan (Intestine-Moistening Pill). It treats conditions where the Stomach is strong but the Spleen is weak, unable to transport and distribute body fluids to moisten the Large Intestine, resulting in dry, hard stools. It also treats cases where the Yuyang pulse (pulse at the dorsalis pedis artery) is floating and choppy, with frequent urination and difficult defecation, classified as Spleen-Restriction syndrome.

This is the Da Cheng Qi Tang with Hou Po and Zhi Ke (Aurantii Fructus) removed, adding Gan Cao, Niu Bang Zi (Arctii Fructus), and Dang Gui. It treats epidemic febrile diseases manifesting as sores and ulcers, throat closure, malaria, and head wind syndromes.

This is the Da Cheng Qi Tang with Sheng Jiang (Zingiberis Rhizoma Recens), Da Zao (Jujubae Fructus), Gui Zhi, and Gan Cao added. It treats abdominal pain and distension/fullness.

This is the Tiao Wei Cheng Qi Tang with Tao Ren, Gui Zhi, Mu Tong (Akebiae Caulis), and Da Fu Pi (Arecae Pericarpium) added. It treats Yang Du Shang Han (Yang Toxicity Cold Damage) that has not yet resolved, with heat condensing internally, presenting with mental confusion and a state resembling madness.

In Taiyang disease, if there is deep inner vexation (Ao Nao), and yang qi sinks inward causing hardness in the epigastrium, this forms Jie Xiong (Chest Binding). In cold damage after six or seven days, if chest binding presents as a heat-excess syndrome with a sinking and tight pulse, pain in the epigastrium...
Da Huang (6 liang, peeled, bitter-cold)
Mang Xiao (1 sheng, salty-cold)
Gan Sui (1 qian bi, bitter-cold)
Take the above three ingredients, boil in 6 sheng of water. First decoct Da Huang until 2 sheng remain, remove the dregs, add Mang Xiao, boil for one or two boils, then add Gan Sui powder. Take 1 sheng warm. If rapid purgation occurs, stop taking the remainder.
Cheng Wuji stated: Da Huang is called the General because its bitterness sweeps away stagnation; Mang Xiao, also known as Xiao Shi, softens hardness due to its salinity; Gan Sui is added in between to unblock fluid retention. Gan Sui acts like clearing a passage through a room, its qi reaching directly to penetrate the condensation and drain the chest. The combination of these three agents is appropriate. Among purgative medicines, this is a drastic agent. Severe cold damage complications involving chest binding are extreme; without this decoction, they cannot be unblocked. If not taken for long...
