Treats conditions caused by Qi deficiency leading to fluid retention (Phlegm-Fluid), vomiting, epigastric fullness and oppression, disharmony of the Spleen and Stomach, and the subsequent emergence of various syndromes.
Ren Shen (Ginseng Radix) 1 qian, Bai Zhu (Atractylodis Macrocephalae Rhizoma) 2 qian, Fu Ling (Poria) 2 qian, Gan Cao (Licorice Radix et Rhizoma) 7 fen, Chen Pi (Citri Reticulatae Pericarpium) 8 fen, Ban Xia (Pinelliae Tuber) 1 qian.
Sha Ren (Amomi Fructus Rotundus) 8 fen, Mu Xiang (Aucklandiae Radix) 7 fen. Add Sheng Jiang (Zingiberis Rhizoma Recens) 2 qian to the above herbs, decoct in water, and take orally.

[Collected Annotations] Ke Qin stated: The *Classic of Difficult Issues* (Nan Jing) says: "Those who are robust recover when Qi moves freely; those who are frail develop disease due to Qi stagnation." Generally, humans exist within the intersection of Heaven and Earth Qi, born from Qi, and the root of generating Qi lies in Stomach Qi. If the Spleen and Stomach remain in disharmony, Qi will stagnate, resulting in epigastric fullness and oppression, hiccups, or vomiting, or the generation of Phlegm and retention of Fluids; consequently, there is a loss of appetite, emaciation, and various syndromes arise, leading to physical wasting and weak respiration. Si Jun Zi Tang (Four Gentlemen Decoction) is the general formula for tonifying Qi. Ren Shen induces harmonious Qi, Bai Zhu cultivates the Middle Jiao (Spleen/Stomach), Fu Ling clears the regulatory organs (Lung), and Gan Cao harmonizes the Five Zang Organs. Once Stomach Qi is regulated, where would disease come from? However, to restore order, one cannot govern through non-action; it is necessary to employ potent Qi-moving agents to assist, so that tonifying substances do not become cloying and stagnant. Therefore, Chen Pi is added to diffuse rebellious Qi of the Lung Metal, and Ban Xia to disperse dampness of the Spleen Earth, thereby eliminating Phlegm and Fluids; Mu Xiang is added to move stagnant Qi of the San Jiao (Triple Burner), and Sha Ren to unblock Yuan Qi of the Spleen and Kidney, thereby opening chest diaphragmatic depression. When the Sovereign herb receives assistance from the four ministers, its efficacy is doubled; when the four ministers serve the Sovereign, Yuan Qi is greatly invigorated, mutually enhancing each other's prominence.

Treats men and women with Blood deficiency presenting similarly to Bai Hu Tang Syndrome (White Tiger Decoction Syndrome), characterized by hot skin, flushed face, irritability, thirst with excessive drinking, a pulse that is flooding yet empty (Hollow), and faint upon heavy pressure.
Dang Gui (Angelicae Sinensis Radix) 2 qian, Huang Qi (Astragali Radix) 1 liang. Decoct in water and take orally.

[Collected Annotations] Wu Kun stated: When Blood is substantial, the body feels cool; when Blood is deficient, the body feels hot. Some individuals suffer Yin-Blood deficiency due to hunger, fatigue, labor, or overexertion, causing Yang to dominate exclusively, thus giving rise to various syndromes. This syndrome presents purely like Bai Hu Tang Syndrome, but the distinction lies in the pulse being large and empty rather than large and excess. As stated in the *Inner Canon* (Nei Jing), an empty pulse indicates Blood deficiency. Among the Five Flavors, only Sweet can tonify. Dang Gui is sweet and thick in flavor; thickness tonifies Blood. Huang Qi is sweet and thin in flavor; thinness tonifies Qi. Although the dosage of Huang Qi is many times greater than that of Dang Gui, this formula is called a Blood-tonifying formula because tangible Blood cannot generate itself; it is generated from intangible Qi. The classics state: "Yang generates, Yin grows"; this is what is meant.
