柯韵伯说：医经说：“身体强壮的人，气机运行通畅则病愈；身体虚弱的人，气机停滞就会成为疾病。”大概人在气交之中，依靠气而生，而生成生气总以胃气为根本。食物进入阴分，滋养阳气于阳分，昼夜循环，周流于内外。一旦气息不运转，就会产生积聚，或者胀满不想进食，或者产生痰液停留水饮，因而肌肉消瘦，气喘咳嗽呕吐呃逆，各种病症蜂拥而起，而神机化育断绝了。四君子汤是气分的总方

必须先调理其气。又说，四物汤如果不加补气药，就不能成就阳生阴长的功效。这话确实正确啊！然而我曾经说这个汤，在伤寒火邪解除之后，余热留在血分，到了夜晚轻微发热不退，或者配合柴胡，或者加入桂枝，没有不随手见效的，不能抹杀它的功劳。
Treats individuals with sallow complexion (mian se wei bai), faint voice, weakness in the four limbs, and a weak pulse. If there is internal heat, or if food is difficult to digest leading to acid regurgitation, this belongs to deficiency fire (xu huo).
It requires:
Ren Shen (Ginseng Radix), Bai Zhu (Atractylodis Rhizoma), Fu Ling (Poria), Gan Cao (Licorice Radix) (each 2 qian).
Decoct in water, add Sheng Jiang (Zingiberis Rhizoma Recens) and Da Zao (Jujubae Fructus).
Add Chen Pi (Citri Reticulatae Pericarpium), it becomes Wu Wei Yi Gong San (Five-Ingredient Decoction for Extraordinary Efficacy). Add Chen Pi (Citri Reticulatae Pericarpium) and Ban Xia (Pinelliae Rhizoma), it becomes Liu Jun Zi Tang (Six-Gentlemen Decoction).
Zhang Luyu said: For Qi deficiency, tonify with sweet flavors. Ren Shen (Ginseng Radix), Bai Zhu (Atractylodis Rhizoma), Fu Ling (Poria), Gan Cao (Licorice Radix) are sweet and warm, benefiting Stomach Qi, possessing the function of strengthening and transporting, and embodying the virtue of harmony.
Therefore, it is

Treats Qi deficiency causing swelling and fullness, accumulation of Phlegm-fluids (Tan Yin), disharmony of Spleen and Stomach, and the generation of various symptoms.
Ren Shen (Ginseng Radix) (1 qian), Bai Zhu (Atractylodis Rhizoma) (2 qian), Fu Ling (Poria) (2 qian), Gan Cao (Licorice Radix) (0.7 qian), Chen Pi (Citri Reticulatae Pericarpium) (0.8 qian), Ban Xia (Pinelliae Rhizoma) (1 qian).
Sha Ren (Amomi Fructus) (0.8 qian), Mu [Xiang] (Saussureae Radix).
Add Sheng Jiang (Zingiberis Rhizoma Recens) 2 qian, decoct in water and take orally.
Ke Yunbo said: The Classics state: "The strong recover as Qi moves; the frail become ill as Qi stagnates." Generally, humans exist within the interaction of Qi, born from Qi, and the generation of vital Qi fundamentally relies on Stomach Qi. Food enters the Yin, nourishing Yang; day and night they cycle, circulating internally and externally. If respiration/Qi movement ceases even for a breath, accumulations form, leading to distension, anorexia, or the production of Phlegm and retention of fluids. Consequently, muscles emaciate, wheezing, coughing, vomiting, and belching arise, various symptoms swarm forth, and the Spirit mechanism (Shen Ji) of transformation is severed. Liu Jun Zi Tang is the general formula for the Qi aspect.

Dang Gui (Angelicae Sinensis Radix), Shu Di Huang (Rehmanniae Radix Preparata) (each 3 qian), Chuan Xiong (Ligustici Chuanxiong Rhizoma) (1.5 qian), Bai Shao (Paeoniae Radix Alba) (2 qian, stir-fried with wine).
The above four ingredients, decoct in water and take orally.
Zhang Luyu said: Si Wu Tang is a specialized agent for diseases affecting Yin-Blood, not the precise formula for tonifying True Yin. Medical texts uniformly claim Si Wu Tang tonifies Yin, thus using it to treat Yin deficiency fever...

Must first regulate its Qi. It is also said that Si Wu Tang cannot achieve the merit of Yang generating Yin without Qi-tonifying herbs. Truly, these words are correct! However, I have often stated that this decoction, after the resolution of Fire pathogen in Shang Han (Cold Damage), where residual heat remains in the Blood aspect, causing slight fever at night that does not cease, when combined with Chai Hu (Bupleuri Radix) or added with Gui Zhi (Cinnamomi Ramulus), responds effectively immediately. Its merits should not be overlooked.
