Jaundice should not be treated with excessive use of cold and bitter drugs. One must examine the deficiency, excess, cold, and heat patterns, and treat according to the specific pathogenesis. All diseases are related to the Spleen and Stomach, and jaundice is particularly a disease of the Spleen and Stomach; it must not be neglected.
Symptoms include yellowing of the body, yellowing of the eyes, and dark yellow urine. Use Huangbai (Phellodendri Cortex), Renshen (Ginseng Radix et Rhizoma), Gange (Puerariae Radix), Shenqu (Massa Medicata Fermentata), and Gancao (Licorice Root) decocted in water for oral administration.
In cases of jaundice accompanied by thirst and a desire to drink tea, the heat is located in the Upper Jiao (Upper Burner); Qingxin Lianzi Yin (Clear the Heart Lotus Seed Decoction) is indicated. If there is epigastric discomfort (gastric clank), the heat is in the Middle Jiao (Middle Burner), and warming the middle is appropriate. If there is no thirst, but symptoms of Lower Jiao Kidney Jaundice occur—such as yellowing of the eyes, whole-body yellowing, and yellow urine—use Qianghuo (Notopterygii Rhizoma et Radix), Fangfeng (Saposhnikoviae Radix), Ben Cao (Ligustici Chuanxiong Rhizoma), Duhuo (Angelicae Pubescentis Radix), and Chaihu (Bupleuri Radix), each 5 fen, and Shengma (Cimicifugae Rhizoma) 2 fen. If urination is obstructed, take 1 qian of Ercha (Karela Gum/Arabic Gum) mixed with a diuretic decoction.
For jaundice caused by summerheat affecting the body and eyes, use Fuling (Poria), Zexie (Alisma Rhizoma), Zhuling (Polyporus), Baizhu (Atractylodis Macrocephalae Rhizoma), each 5 fen; Cangzhu (Atractylodis Rhizoma) 1 qian; and Shenqu (Massa Medicata Fermentata) 2 qian, decocted in water.
Thirst indicates Stomach Fire. Dry mouth without thirst, especially at night, results from Mingmen Ministerial Fire and Pericardium Fire steaming the Lung, depleting Lung fluids. Use Huangqi (Astragali Radix) 3 qian and Danggui Shen (Angelicae Sinensis Radix) 3 qian to moisten; continuous use will lead to recovery. The use of Baihu Tang (White Tiger Decoction) would be fatal. If dry mouth is accompanied by fever, indicating severe Lung dryness, use raw Huangqi 8 qian and Danggui Shen 4 qian to moisten. For internal injury causing fever, dry mouth, and thirst, add Paojiang (Prepared Ginger) 2 qian to Yiqi Tang (Qi-Boosting Decoction).
Excessive thirst with copious drinking characterizes Xiao Ke (Wasting-Thirst Disease). Use Huangqi 9 qian and Gancao 3 qian, decocted and taken orally.
In Shang Xiao (Upper Wasting-Thirst), drinking hundreds of cups does not quench thirst; clearing the Lung is indicated. Use Maidong (Ophiopogonis Tuber), Wuweizi (Schisandrae Fructus), and Huanglian (Coptidis Rhizoma) decocted. Alternatively, make pills using Tiaohuang Qin (Scutellariae Radix), Xingren (Armeniacae Semen Amarum), Gualou (Trichosanthis Fructus), Zhizi (Gardeniae Fructus), Yuanshen (Scrophulariae Radix), and Ganjiang (Zingiberis Rhizoma), each 3 qian; Hezi (Terminalia Chebulae Fructus) and Renshen 5 qian. To specifically tonify insufficient Spleen Yin, use Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) made into pills with rice paste.
In Zhong Xiao (Middle Wasting-Thirst), frequent eating does not satisfy hunger, or excretion contains purulent turbid matter resembling bean dregs (red and white); this condition is difficult to cure. This occurs because although food intake is high, satiety is not reached, and despite high fluid intake, thirst persists, due to insufficient Spleen Yin. Use Shanyao (Dioscoreae Rhizoma), Danggui Shen, Fuling, Chenpi (Citri Reticulatae Pericarpium), Gancao, and Yiren (Coicis Semen). Alternatively, clear Spleen Fire using Dahuang (Rhei Radix et Rhizoma), Zhizi, Shigao (Gypsum Fibrosum), Kuqin (Scutellariae Radix), Lianqiao (Forsythiae Fructus), and Wumei (Mume Fructus), each 2 qian; Hezi and Renshen 5 qian. Or, cook 5 fen of Huanglian inside a pig’s stomach and eat it. Or, make pills with equal parts of Chuanlian (Coptidis Rhizoma) and Baizhu.
In Xia Xiao (Lower Wasting-Thirst), caused by sexual excess leading to persistent erection (Yu Jing Bu Wei), clearing the Kidney is indicated. Use Huangbai and Zhimu (Anemarrhenae Rhizoma); or Huangbai, Zhimu, Zexie, Zhizi, Shengdi (Rehmanniae Radix), and Wuweizi, each 2 qian; Hezi and Renshen 5 qian.
Case Record:
One patient suffered from excessive mental exertion, drank dozens of cups of tea daily, felt spiritually exhausted, and preferred lying down. This was Heart Fire invading the Spleen, causing Stomach dryness and failure of Kidney Water to rescue; it was named Shen Xiao (Kidney Wasting-Thirst). Use Huangqi, Wuweizi, and Shengdi, each 5 fen; Renshen, Maidong, and Danggui Shen, each 1 qian, decocted in water.
Another patient, who usually loved tea and suffered from excessive mental exertion, had even more severe thirst accompanied by nausea. The pulse was deficient on superficial palpation, short and rapid at the Guan positions on deep palpation, and weak at the Chi positions on deep palpation. This resulted from excessive thinking, causing Water to fail to ascend and Fire to fail to descend. The rapid pulse indicated excess Stomach Qi. Tonifying Yang within Yin was appropriate. Use Renshen, Baishao (Paeoniae Radix Alba), and Danggui Shen, each 1 liang; Shanyao, Fuling, Shudi (Rehmanniae Radix Preparata), and Gouqizi (Lycii Fructus), each 2 liang; Gancao and Wuweizi, each 5 qian; and Suanzaoren (Ziziphi Spinosae Semen) 1.5 liang, made into pills.
