Treats continuous spontaneous sweating, Qi deficiency with weak exterior resistance, and susceptibility to wind-cold (Yang has the function of guarding the exterior and maintaining consolidation; when Yang is deficient and cannot guard the exterior, body fluids are not consolidated).

Huangqi (Honey-fried, 4 liang) Fangfeng (1 liang) Baizhu (Stir-fried, 2 liang). Grind into fine powder. Take 3 qian per dose.

This prescription acts on the Foot-Taiyang Bladder Meridian, Hand-Taiyin Lung Meridian, and Foot-Taiyin Spleen Meridian. Huangqi tonifies Qi and specifically consolidates the muscular exterior, thus serving as the Sovereign herb; Baizhu benefits the Spleen, and the Spleen governs the muscles, thus serving as the Minister herb; Fangfeng dispels wind and acts as a vanguard among wind-dispelling herbs, yet Huangqi fears it (referring to their mutual restraint and promotion), thus serving as the Envoy herb. Because it benefits Wei-Qi and consolidates the exterior, it is named Yupingfeng San (Li Dongyuan stated: "When Huangqi is combined with Fangfeng, its efficacy is greatly enhanced, taking advantage of their mutual fear and mutual assistance." *Zhunsheng* stated: "In cases of stroke with hemiplegia, there is none that does not arise from the failure of True Qi to circulate freely. Therefore, Huangqi is an indispensable Sovereign herb, and Fangfeng is an indispensable Minister herb. Huangqi assists True Qi, while Fangfeng carries the Qi assisted by Huangqi to circulate throughout the body, also possessing the function of treating wind pathogens." Xu Yinzong treated Empress Dowager Wang's stroke with locked jaw by fumigating her with a decoction of these two herbs, curing her; how much more so if taken internally?)

If the aforementioned herbs are decocted in equal proportions, it is named Huangqi Tang: Jiegao used this formula to substitute Guizhi Tang for treating fever with sweating, weak pulse, aversion to wind and cold during spring and summer. If aversion to wind is severe, add Guizhi. Also, using Chuanxiong, Cangzhu, and Qianghuo in equal proportions, it is named Chuanxiong Tang; used to substitute Mahuang Tang for treating fever without sweating, aversion to wind and cold during autumn and winter.

Treats all conditions of Yang deficiency and weak Qi, Spleen decline and Lung damage, lack of appetite, emaciation with sallow complexion, dry skin and falling hair, and a fine, soft pulse (The Spleen is the mother of all things, the Lung is the mother of Qi; once the Spleen and Stomach are deficient, Lung Qi fails first. The Spleen fails to transport and transform, hence lack of appetite; reduced food intake means Ying-Wei [Nutritive and Defensive Qi] have no source...).

Renshen (Ginseng Radix et Rhizoma) Baizhu (Earth-stir-fried) Fuling (2 qian) Gancao (Licorice Root, 1 qian). Decoct with 3 slices of Shengjiang (Fresh Ginger) and 2 Zao (Jujube fruits).

This prescription acts on the Hand-Taiyin Lung Meridian, Foot-Taiyin Spleen Meridian, and Foot-Yangming Stomach Meridian. Renshen is sweet and warm, greatly tonifying Yuan Qi, serving as the Sovereign herb; Baizhu is bitter and warm, drying dampness and tonifying Spleen Qi, serving as the Minister herb; Fuling... receives its influence... therefore...

Adding Chenpi (Citrus Peel) to this base formula creates Yigong San (created by Qian Yi): regulates the Spleen and Stomach.

Liushen San (created by Chen Wuyue): treats children who develop fever again after the release of exterior heat (Secular physicians at this stage often fail to understand, either administering cooling medicines again, attempting to release the exterior again, or declaring it untreatable. This is because both interior and exterior are deficient, and Qi fails to return to its origin... Decoct to harmonize Stomach Qi, thereby converging Yang to return inward, and the body will cool.)
