(From *Jingui Yaolue*)
Treats Wind-Water disease, characterized by aversion to wind, generalized edema, a floating pulse without thirst, continuous spontaneous sweating, and absence of significant heat on the body surface. (The classics state: When the Kidney and Liver pulses are both deep, it is Stone Water; when both are floating, it is Wind-Water. Water residing in the skin causes the floating pulse; absence of internal heat causes lack of thirst; the root cause being Wind leads to sweating and aversion to wind; "absence of significant heat" means the pathogenic heat has not fully subsided.)

Ephedrae Herba (Mahuang, 麻黄) [6 liang], Gypsum Fibrosum (Shigao, 石膏) [8 liang], Zingiberis Rhizoma Recens (Shengjiang, 生姜) [3 liang], Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) [2 liang], Jujubae Fructus (Dazao, 大枣) [12 pieces]. If aversion to wind is prominent, add Aconiti Lateralis Radix Praeparata (Fuzi, 附子).
This formula acts on the Foot-Taiyang Bladder Meridian. Wind-Water pathogens reside between the skin and muscles; Ephedrae Herba's pungent and hot nature drains Lung Qi, while Gypsum Fibrosum's sweet and cold nature clears Stomach Heat (the Lung governs the unimpeded flow of water passages, and the Stomach distinguishes food and fluids). Glycyrrhizae Radix et Rhizoma serves as an assistant, enabling the Wind-Water pathogens to exit through the pores. Ginger and Jujube act as envoys to harmonize Ying and Wei (Nutritive and Defensive Qi), preventing excessive dispersion that would consume body fluids (The Stomach is the master of the twelve meridians; the Spleen processes food and fluids like a humble servant; the classics state: The Spleen transmits fluids for the Stomach. This formula is named Yuebi...)

(From *Jingui Yaolue*)
Treats Wind-Water disease with a floating pulse, heaviness of the body, sweating, and aversion to wind (symptoms explained previously); as well as numbness and body pain caused by various Wind and Dampness pathogens. (Note: Li Dongyuan stated that numbness is caused by Wind, a fact known even to children. However, upon close examination, distinctions exist: prolonged sitting causes numbness, and those bound by ropes also experience numbness; this is not due to Wind pathogens but rather stagnation of Qi, requiring supplementation of Lung Qi...)

Stephaniae Tetrandrae Radix (Fangji, 防己) and Astragali Radix (Huangqi, 黄芪) [each 1 liang], Atractylodis Macrocephalae Rhizoma (Baizhu, 白术) [7.5 qian], Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) [5 qian, honey-fried]. Take 5 qian per dose. Decoct with Ginger and Jujube.
If abdominal pain occurs, add...
If the pulse is vigorous, add Poria (Fuling, 茯苓) and Atractylodis Rhizoma (Cangzhu, 苍术)...
This formula acts on the Foot-Taiyang Bladder Meridian and Foot-Taiyin Spleen Meridian. Stephaniae Tetrandrae Radix is greatly bitter and acrid in flavor and cold in nature, circulating through the twelve meridians, opening orifices and draining Dampness; it is the primary herb for treating Wind-Edema and Water-Edema. Astragali Radix, used raw, reaches the exterior, treats pain from Wind stagnation in the skin, warms the muscle layer, and consolidates the interstices. Atractylodis Macrocephalae Rhizoma strengthens the Spleen and dries Dampness; combined with Astragali Radix, it can stop sweating, serving as the Deputy herb. Stephaniae Tetrandrae Radix's nature...

Removing Atractylodis Macrocephalae Rhizoma, Ginger, and Jujube from this formula, adding Poria as the Sovereign herb, and adding Cinnamomi Ramulus (Guizhi, 桂枝), it is named Fangji Fuling Tang (from *Jingui Yaolue*); it treats Water in the skin, where the four limbs tremble slightly, termed Pi-Shui (Skin Water). (Stephaniae Tetrandrae Radix circulates the collaterals, Poria facilitates seepage and excretion, Astragali Radix reaches the skin, and Cinnamomi Ramulus travels to the joints. Note: Among the five types of Water diseases, if the pulse is floating with aversion to wind and joint pain, it is Feng-Shui (Wind-Water); if the pulse shows swelling, depression upon pressure remains, the abdomen is drum-like, there is no aversion to wind or thirst, it is Pi-Shui (Skin Water), which requires inducing sweating. It is also said: Aversion to cold without thirst indicates Feng-Shui; no aversion to cold but with thirst indicates Pi-Shui; even if Pi-Shui presents without thirst, sweating should still be induced. A deep and slow pulse with spontaneous asthma indicates Zheng-Shui (Correct Water); a deep pulse with abdominal fullness but no asthma, with water accumulating in the bladder/uterus, hard and full like stone, indicates Shi-Shui (Stone Water); a deep and slow pulse with fever, chest fullness, generalized edema, and sweat resembling paulownia juice indicates Huang-Zhi (Yellow Sweat).) Adding Ginseng Radix (Renshen, 人参) [1 liang] and Zingiberis Rhizoma Recens (Shengjiang, 生姜) [2 liang], and tripling the dosage of Stephaniae Tetrandrae Radix and Atractylodis Macrocephalae Rhizoma, it is named Fangji Tang (from *Ren Shu*); it treats Wind-Warmth disease with a floating pulse, profuse sweating, and body heaviness (The pulse of Wind-Stroke is floating and slippery at the Yang position, and soft and weak at the Yin position; when Wind attacks with Heat, it transforms into Wind-Warmth, for which sweating methods are contraindicated; if sweating was mistakenly induced, this formula is used to rescue the patient).
