Treats middle jiao fullness, cold distension, cold hernia, obstruction of both urination and defecation, cold limbs (Jue Ni), regurgitation after eating, cold in the abdomen, epigastric stuffiness (Xin Xia Pi), deficiency at the lower origin with yin restlessness, and rushing qi that cannot be restrained. (The original text states: This occurs in those who consume excessive cold and cool substances or have long-standing spleen and stomach deficiency. Cold in the stomach leads to distension; cold in the zang organs leads to fullness diseases. This decoction is indicated.)
Chuanwu (Radix Aconiti Lateralis Preparata), Ganjiang (Rhizoma Zingiberis), Bichengqie (Fructus Tetradii), Shengjiang (Rhizoma Zingiberis Recens), Huanglian (Rhizoma Coptidis), Renshen (Radix Ginseng), Danggui (Radix Angelicae Sinensis), Zexie (Rhizoma Alismatis), Qingpi (Pericarpium Citri Reticulatae Viride), Mahuang (Herba Ephedrae), Chaihu (Radix Bupleuri) (each 2 qian); Wuzhuyu (Fructus Evodiae), Cao Kou Ren (Semen Karyae Arecae Condimentum), Houpo (Cortex Magnoliae Officinalis), Huangqi (Radix Astragali), Huangbai (Cortex Phellodendri) (each 5 fen); Yizhiren (Semen Alpiniae Oxyphyllae), Muxiang (Radix Aucklandiae), Banxia (Rhizoma Pinelliae), Fuling (Poria), Shengma (Rhizoma Cimicifugae) (3 fen). Take warm.
These are herbs for the Foot-Yangming and Foot-Taiyin meridians. Chuanwu, the two types of ginger (Ganjiang, Shengjiang), Wuzhuyu, Bichengqie, Yizhiren, and Cao Kou Ren dispel dampness and open stagnation, warm the stomach and kidney to eliminate cold within. The heat contained within is treated by "using heat for cold" methods. (Li Dongyuan said: The treatment for middle jiao fullness should involve opening the ghost gate (Kai Gui Men) and purifying the bladder house (Jie Jing Fu). Opening the ghost gate refers to inducing sweating; purifying the bladder house refers to promoting urination. For middle jiao fullness, one must drain from within, meaning when the spleen and stomach are diseased, dampness should be dispersed from above and below. The lower jiao is like a ditch, allowing qi and blood to differentiate naturally.)

Treats internal attack by damp-heat, abdominal distension and fullness, difficult urination, loose diarrhea; as well as edema and other syndromes (urine mixes into the large intestine, hence difficult urination and loose diarrhea).
Huashi (Talcum), Gancao (Radix Glycyrrhizae) (1 qian), Chi Fuling (Poria cum Rhizomo Polypori), Zhuling (Polyporus), Zexie (Rhizoma Alismatis), Baizhu (Rhizoma Atractylodis Macrocephalae, stir-fried with soil), Guizhi (Ramulus Cinnamomi) (5 fen), Chenpi (Pericarpium Citri Reticulatae) (1.5 qian), Muxiang (Radix Aucklandiae), Binglang (Semen Arecae) (3 fen). Decoct with fresh ginger. Each dose is 5 qian.
These are herbs for the Foot-Taiyang meridian. Chi Fuling, Zhuling, and Zexie drain fire and move water; Baizhu tonifies the spleen; Rougui (Cortex Cinnamomi) transforms qi. This constitutes Wu Ling San (Five-Ingredient Powder with Poria); Huashi is a heat-clearing agent.

(Zhang Zhongjing)
Treats Yangming disease of Shang Han (Cold Damage), characterized by sweat only on the head, abdominal fullness, thirst, obstruction of urination and defecation, jaundice due to damp-heat, and a deep, solid pulse. (The classics state: In Yangming disease with fever, there must be sweating, but if only the head sweats...)
Yinchen (Herba Artemisiae Scopariae) (6 liang), Dahuang (Radix et Rhizoma Rhei, soaked in wine) (2 liang), Zhizi (Fructus Gardeniae) (14 pieces, stir-fried).
These are herbs for the Foot-Yangming meridian. Cheng Wuji said: Mild heat is harmonized with cool herbs; severe heat is thoroughly cleared with cold herbs. Jaundice indicates severe damp-heat, which cannot be cleared without potent cold herbs; thus, Yinchen is used as the Sovereign herb (Yinchen induces sweating and promotes urination to drain damp-heat from the Taiyin and Yangming, making it the primary herb for treating jaundice); Zhizi is the Minister herb; Dahuang is the Assistant herb. By draining through the anterior and posterior orifices respectively, the abdomen benefits and the disease resolves. Yinchen and Zhizi guide damp-heat out via urination; Dahuang guides damp-heat out via defecation.
If Dahuang in this formula is replaced by Huanglian, it is named Yinchen Sanwu Tang (Three-Ingredient Decoction with Yinchen): indications are the same. If Houpo, Zhishi, Huangqin, and Gancao are added to this formula, along with fresh ginger and Dengcao (Lampwick), it is named Yinchen Jiangjun Tang (Yinchen General Decoction) (Jie'an said): indications are the same. If Zhizi and Dahuang are removed from this formula and Fuzi (Radix Aconiti Lateralis Preparata) and Ganjiang are added, it treats cold-damp Yin Jaundice (The previous syndrome is Yang Jaundice; if the body is yellow and the color is dull, it is Yin Jaundice, for which this decoction is suitable. Generally, treatment focuses on Yinchen, adjusting herbs according to cold or heat. For all types of jaundice, yellow and turbid urine with difficulty indicates interior excess, suitable for promoting urination or purgation; absence of sweating indicates exterior excess, suitable for diaphoresis or emesis; if urine is clear, there is no heat. Zhang Zhongjing stated: For jaundice with spontaneous free urination, Xiao Jianzhong Tang from the Deficiency Consumption chapter should be given; for spontaneous diarrhea with abdominal fullness and wheezing, heat-clearing is contraindicated, as it will cause hiccups; Xiao Banxia Tang is indicated. Wang Haicang said: Internal contraction of Shang Han, physical exhaustion, irregular diet leading to cold transformation in the middle jiao causes jaundice; not acquired from external pathogens, only...)
