[Symptoms of Xuan Yin (Hanging Fluid)] After drinking, water fluid accumulates in the hypochondrium. Coughing and expectoration cause rebellious Qi flow, pulling and causing pain in the chest and ribs. This is called Xuan Yin (Hanging Fluid), which refers to the Xuan Yin described in *Jin Gui Yao Lue* (Essential Prescriptions from the Golden Cabinet).

[Etiology of Xuan Yin] Indiscretion in diet and lack of caution in drinking fluids impair the transportation and transformation functions of the Spleen and Lung. Water fluid stagnates in the hypochondrium and attacks the Lung upwards, resulting in cough, expectoration, and rebellious Qi. It obstructs the ascending and generating function of the Liver and Gallbladder, causing pain that radiates to the chest and ribs, thereby forming the syndrome of Xuan Yin.

[Pulse of Xuan Yin] The pulse may be deep (Chen) or wiry (Xian). A deep pulse indicates the presence of water fluid, hence it is called Xuan Yin. A wiry pulse indicates Qi knotting/stagnation, hence internal pain.

[Treatment of Xuan Yin] *Jin Gui Yao Lue* prescribes only one formula: if the pulse is deep and wiry, indicating Xuan Yin with internal pain, Shi Zao Tang (Ten Jujube Decoction) is the primary treatment. Since Xuan Yin is characterized by pain, a purgative method is used. I have further expanded upon this with two additional formulas: Gun Tan Wan (Rolling Phlegm Pill) and Jia Wei Er Chen Tang (Modified Two-Cured Decoction).

Shi Zao Tang (Note: Text says Da Zao Tang, but ingredients match Shi Zao Tang contextually, though strictly translating text as "Da Zao Tang" per instruction to keep names):
Yuan Hua (Genkwa Flos)
Gan Sui (Radix Euphorbiae Kansui)
Da Ji (Radix Euphorbiae Hussonis)

Gun Tan Wan (Rolling Phlegm Pill)
Qing Meng Shi (Lapis Calaminaris)
Da Huang (Radix et Rhizoma Rhei)
Chen Xiang (Aquilariae Lignum Resinatum)
Huang Qin (Scutellariae Radix)

Jia Wei Er Chen Tang (Modified Two-Cured Decoction)
Shu Ban Xia (Rhizoma Pinelliae Preparatum)
Bai Fu Ling (Poria)
Guang Pi (Citri Reticulatae Pericarpium)
Gan Cao (Glycyrrhizae Radix et Rhizoma)
Zhi Shi (Aurantii Fructus Immaturus)
Jie Geng (Platycodonis Radix)
Xing Ren (Armeniacae Semen Amarum)
Gua Lou Ren (Trichosanthis Semen)
If there is heat, add Chuan Lian (Coptidis Rhizoma). If cough is severe, add Bei Mu (Fritillariae Bulbus). Tao Hua Shi (Tao Huashi) uses this formula to treat phlegm knotting in the chest and hypochondrium.

[Symptoms of Yi Yin (Overflowing Fluid)] Water-Qi flows and distributes to the four limbs. The body feels heavy and painful, and the joints are vexed and painful. This is called Yi Yin (Overflowing Fluid).

[Etiology of Yi Yin] When fluid enters the Stomach, its essence spreads and is transported upward to the Spleen. The Spleen scatters the essence upward to the Lung, which regulates the water passages and transports it downward to the Bladder. However, if too much fluid is consumed, its cold nature causes Qi stagnation and rebellion. Rebellious Qi causes fluid to overflow into the four limbs. Sweating should occur to release it, but sweating fails; thus, it cannot disperse outward. The body becomes heavy due to dampness and painful due to cold. Hence, the heaviness and pain of the body constitute the syndrome of Yi Yin.

[Pulse of Yi Yin] *Jin Gui Yao Lue* states: "A pulse that is deep and rapid, or deep and wiry, indicates Xuan Yin." It also states: "For patients with Yi Yin, sweating should be induced," but does not mention the pulse image. I surmise that the pulse must be floating and large or floating and tight, rather than deep and wiry or deep and rapid.

[Treatment of Yi Yin] *Jin Gui Yao Lue* treats internal pain of Xuan Yin with Shi Zao Tang. It also states: "For patients with Yi Yin, sweating should be induced; Da Qing Long Tang (Major Green Dragon Decoction) is the primary treatment, and Xiao Qing Long Tang (Minor Green Dragon Decoction) is also applicable." Xuan Yin has a deep and wiry pulse, with fluid hanging internally causing pain, so a purgative method is used. Yi Yin has fluid overflowing externally, so a diaphoretic (sweating) method is used.

Shi Zao Tang See previous section on Xuan Yin.

Da Qing Long Tang (Major Green Dragon Decoction) Treats Yi Yin presenting with heavy and painful body, and vexed and painful joints, requiring induction of sweating.
