Taiyang disease (Disease of the Taiyang/Bladder channel) after sweating therapy, resulting in continuous leakage of sweat, aversion to wind (fear of wind), difficulty in urination, slight stiffness of the four limbs making flexion and extension difficult, this formula is indicated.
Guizhi Tang (Cinnamon Twig Decoction) with one Fuzi (Prepared Aconite Lateral Root) (processed, skin removed, broken into eight pieces). The decoction and administration method are the same as before; there is no need to drink warm porridge to assist sweating.

[Collected Annotations] Ke Qin stated: Excessive sweating causes Yang Qi to have no place to rest, leading to unceasing sweat leakage. Profuse sweating leads to loss of Yang Qi, failure of Yuanfu (pores/sweat orifices) to close, allowing Wind to enter due to deficiency, hence the recurrence of aversion to wind; fluids leak outward and cannot moisten downward, hence difficulty in urination. The four limbs are the root of all Yang channels; Yang Qi softens and nourishes the sinews. When opening and closing functions fail, Wind-Cold enters following it, causing sinew stiffness and inability to flex or extend. This formula adds Fuzi to Guizhi Tang to greatly tonify Exterior Yang. When Exterior Yang is secure, leaking sweat stops naturally, and aversion to wind subsides. When sweat stops and fluids return, urination becomes smooth, and the limbs become supple. Continuous sweat leakage is similar to profuse sweating, but the pathological transformation differs. After taking Guizhi Tang or Mahuang Tang, if profuse sweating occurs accompanied by great irritability and thirst, it indicates Yang sinking into the Interior, requiring urgent preservation of Yin, thus Baihu Jia Renshen Tang (White Tiger Decoction plus Ginseng) is used. After taking Guizhi Tang or Mahuang Tang, if profuse sweating occurs followed immediately by continuous leakage, it indicates Yang escaping to the Exterior, requiring urgent rescue of Yang, thus Guizhi Jia Fuzi Tang (Cinnamon Twig Decoction plus Prepared Aconite) is used. It must be known that when using diaphoretic agents, improper use of Guizhi often leads to Yang sinking into the Interior; improper use of Mahuang often leads to Yang escaping to the Exterior. Because Guizhi Tang contains Shaoyao (Peony Root) but lacks Mahuang, even if sweating is profuse, the Yuanfu can still close itself, so it rarely leads to loss of Yang on the Exterior.

After sweating, the disease resolves, yet aversion to cold persists; this is due to deficiency, and this formula is indicated.
Shaoyao (Peony Root) 3 liang, Gancao (Honey-fried Licorice Root) 2 liang, Fuzi (Prepared Aconite Lateral Root) 1 piece (processed, skin removed, broken into eight pieces). These three ingredients are boiled in five sheng of water until one sheng and five he remain. Strain the dregs and administer warm in divided doses.

[Collected Annotations] Ke Qin stated: After sweating, the disease resolves but aversion to cold worsens compared to before sweating, indicating Yang deficiency. Taiyang (Bladder) and Shaoyin (Kidney) are interior-exterior pairs. Diseases of Taiyang originate from Shaoyin deficiency, which fails to store essence to guard Yang. Now, aversion to cold appears after the resolution of the disease via sweating, indicating that the Cold pathogen has been resolved through sweat, but Taiyang Yang is deficient and cannot defend the exterior against Yin, signaling the onset of Yang collapse. If one were to continue attacking the exterior with Guizhi Tang, it would not support Yang but rather deplete it. Therefore, Shaoyao is used to gather the essence and Qi of Shaoyin, Gancao to slow the upward movement of Yin pathogens, and Fuzi to tonify the Lesser Fire of Kan Palace (Kidney). As long as the Primordial Yang in the Kidney assumes its proper position, the aversion to cold caused by deficient Yang on the exterior will resolve spontaneously.
