Jaundice mostly belongs to the Taiyin Spleen Meridian. When the Spleen fails to overcome dampness and additionally harbors heat-fire, damp-heat stagnates and generates yellowing, similar to the process of making koji: wet materials exposed to summer heat and covered up, where damp-heat contend with each other, resulting in yellow color. This corresponds to the Classic saying, "When damp-heat attack mutually, the people shall suffer from jaundice." Therefore, jaundice must first present with red urine and yellow eyes. The Classic states: "Red urine accompanied by a desire to lie down indicates jaundice." Red urine is a symptom of heat; lying down (lethargy) is a symptom of dampness. It also states: "Yellow eyes indicate jaundice." The eyes are the gathering point of numerous meridians; if damp-heat exists in various meridians, it steams upward to the eyes, causing yellowing there first. However, dampness and heat have their distinctions. Jaundice dominated by dampness has a dark and dull color; jaundice dominated by heat has a bright and lustrous color. In general treatment principles, if accompanied by exterior syndrome, the pulse is floating. Recovery can be achieved through sweating methods, using herbs such as Puerariae Radix (Gegen), Menthae Haplocalycis Herba (Bohe), Gentianae Macrophyllae Radix et Rhizoma (Qinjiao), and Fermented Soybean (Danchi). The *Jin Gui Yao Lue* states: "Diseases originating in the Yang aspect manifest with chills and fever." It further states: "If the pulse is floating, it should be resolved through sweating," which refers to this principle. If accompanied by interior syndrome with abdominal distension, relief can be achieved through purgation, using formulas such as Yinchen Hao Tang. The *Jin Gui Yao Lue* states: "In cases of jaundice with abdominal fullness, difficult urination with red urine, and spontaneous sweating, this indicates the exterior is resolved but the interior is excess; it should be treated with purgation," referring to this principle. Caused by food injury, it is called Grain Jaundice (Gu Dan). The *Jin Gui Yao Lue* states: "The disease of Grain Jaundice presents with alternating chills and fever, anorexia, dizziness after eating, mental restlessness, and eventual yellowing over time, which is Grain Jaundice." Treatment should focus on resolving food stagnation, assisted by herbs that clear heat and promote diuresis to remove dampness. Caused by alcohol injury, it is called Wine Jaundice (Jiu Dan). The *Jin Gui Yao Lue* states: "Vexation and heat in the heart, inability to eat, and frequent urge to vomit constitute Wine Jaundice." Treatment should resolve alcohol toxicity and food stagnation, assisted by agents that clear heat and promote diuresis to remove dampness. If the pulse is deep and forceful, with acute binding in the lower abdomen, free urination, hard stools that are easy to pass, and black color, this is jaundice due to blood stasis. Treatment should use formulas such as Xijiao Dihuang Tao Ren Chengqi Tang. There are also cases with a deep, fine, and slow pulse, cold body with spontaneous sweating, diarrhea, and white urine, belonging to Spleen and Kidney Deficiency-Cold, named Yin Jaundice. Treatment should follow formulas such as Yinchen Sini Tang. However, jaundice mostly belongs to damp-heat. Only Luo Qianfu stated that there are cases where excessive use of cold-cooling herbs causes Yang Jaundice to transform into Yin syndrome, which is rare, occurring once or twice in thousands of cases. As for jaundice caused by sexual exhaustion injuring the Kidney, the symptoms described in the *Jin Gui Yao Lue* are: "Black forehead, slight sweating, hot hands and feet, fever and chills starting at dusk. [This is Kidney Yin Deficiency.] Urgency of the Bladder, fullness of the lower abdomen, free urination, and stools that are necessarily black yet occasionally loose, named Woman-Labor Jaundice (Nv Lao Dan). Abdominal distension resembling water accumulation is untreatable. Jiayan [Zhang Jingyue] said: Men's blood transforms into essence; when essence moves, the blood of the whole body moves. Depleting essence through woman-labor causes subsequent damage to blood. Therefore, hematuria caused by woman-labor, where blood still flows, is relatively easy to treat; jaundice formed from woman-labor, where blood is stagnant and does not flow, is difficult to treat. Thus, urgency of the Bladder, fullness of the lower abdomen, free urination, and black, occasionally loose stools are all signs of Blood Accumulation in the Bladder. Severe cases involve long-term blood stasis leading to total abdominal distension, forming Blood Gu, indicating the failure of both Pre-heaven and Post-heaven roots. Hence, it is said that the abdomen resembles water, but it is actually not water. Observing Zhang Zhongjing's use of Nitrum (Xiaoshi) and Alum (Fan) to eliminate stasis and turbidity, taken with Barley Decoction, introduces the remedy into the intestines and stomach, allowing stasis to exit via both bowels. Without urgently removing the stasis from the Bladder and lower abdomen, there is no hope. However, Maggot (Meng) and Leech (Zhi) are not used, fearing their action is too harsh for treating woman-labor jaundice. Yu Tianmin said: For such cases with long-term Kidney Essence deficiency and extreme Qi exhaustion, one must strengthen the master of Water [nourish Kidney Yin], assist with Ginseng Radix et Rhizoma (Renshen) to cultivate the source of Qi, and add damp-heat resolving agents according to symptoms, achieving simultaneous treatment of root and branch, possibly yielding results. Generally speaking, jaundice treatment focuses on clearing heat, removing dampness, and promoting diuresis, while supporting Stomach Qi. For food injury, resolve food accumulation; for alcohol injury, resolve alcohol toxin; for blood stasis, move blood stasis. Although sweating and purging methods exist, sweating is rarely used lightly, and purging must also be applied cautiously. Thus, ancients said: Treating jaundice contraindicates heavy sweating, heavy purging, warming-tonifying dry-hot herbs, and qi-breaking or qi-stagnating agents; this must be known.

Yinchen Zhidan Decoction [Self-made]. The *Jin Gui Yao Lue* states: "Jaundice arises from dampness. [Dampness mixed with heat-fire leads to stagnation and yellowing.]" It also states: "For all jaundice patients, simply promote urination." This formula is modified based on this.
Yin Chen Hao (Artemisiae Scopariae Herba), Huang Qin (Scutellariae Radix) [Clear heat and remove dampness], Hei Shan Zhi (Gardeniae Fructus), Hua Shi (Talcum), Fu Ling (Poria), Che Qian Cao (Plantaginis Herba) [Promoting urination removes dampness naturally. Using only one herb, crushed with roots and drunk, yields miraculous effects], Ju Hong (Citri Reticulatae Pericarpium Rubrum) [Qi transformation allows dampness to move naturally]. Reference Mugen Gen (Imperatae Rhizoma); add Huang Lian (Coptidis Rhizoma) for severe heat; add Maidong (Ophiopogonis Radix) and Huafen (Trichosanthis Radix) for thirst; add Shanzha (Crataegi Fructus) and Maiya (Hordei Fructus Germinatus) for food injury; add Wei Gegen (Puerariae Radix Preparata) and Ganshe Jiang (Sacchari Sinarum Liquamen) for alcohol injury.
This formula clears heat, removes dampness, transforms Qi, and promotes diuresis, following Zhongchun's method for treating jaundice.

Experience Zhidan Decoction
Sheng Di Huang (Rehmanniae Radix) [3 qian. Nourishes Yin and moistens blood dryness], Dang Gui (Angelicae Sinensis Radix) [Moistens blood dryness], Hong Hua (Carthami Flos) [Moves blood stasis], Ju Hong (Citri Reticulatae Pericarpium Rubrum), Zhi Ke (Aurantii Fructus) [1 qian each], Hou Po (Magnoliae Officinalis Cortex) [Resolves stagnation, 8 fen], Huang Qin (Scutellariae Radix) [2 qian], Huang Lian (Coptidis Rhizoma) [Clears damp-heat, 5 fen, increase dosage if heat is severe], Che Qian Zi (Plantaginis Semen) [Promotes urination, 2 qian], E Mao Jun Chen (Artemisiae Scopariae Herba variant), Yao Ling Yin Chen (Artemisiae Scopariae Herba variant) [5 qian each]. Decoct in water [1 bowl] and Baijiu [1 bowl]. Add Chao Sha Ren (Amomi Fructus Rotundus Preparatus) [4 fen], take with decoction.
This formula nourishes Yin, invigorates blood, clears heat, and removes dampness. After several doses, the yellowing will gradually recede.

*Jin Gui Yao Lue* Pig Fat and Hair Decoction treats all types of jaundice generally. [Jaundice arises from damp-heat stagnation; over time, Yin and Blood are consumed. Regardless of Qi or Blood level, nourishing Yin is appropriate.] It also treats Woman-Labor Jaundice and Yellow Sweat Disease. [Sweat like paulownia sap juice, caused by entering water while sweating, allowing water to enter through pores.]
Zhu Gao (Pinguinis Porci) [Opens both bowels, eliminates five types of jaundice], Luan Fa (Capillis Humanis) [Eliminates blood stasis, promotes urination, washed clean, 4 liang each]. [Simmer hair with fat until hair dissolves and medicine forms; divide into two doses; pathogen exits via urination.] For Woman-Labor Jaundice, add Sheng Di Huang (Rehmanniae Radix), Niu Xi (Achyranthis Bidentatae Radix), Bie Jia (Testudinis et Testae Carapacis et Plastrum) [Tonify Yin and eliminate stasis], Fen Liang (Trichosanthis Radix) [Clears heat and treats jaundice], Nu Ren Jing Yi Hui (Ash of Menstrual Cloth) [Similarity attracts similarity, Qi resonates, guides out pathogenic heat]. These are applicable ingredients.
This is a formula for moistening dryness, eliminating stasis, and promoting diuresis, used here to treat damp-heat. Pig Fat borrows the power of Hair to enter the Blood level and moisten blood dryness, and uses its power to open Bladder stasis and promote urination to remove damp-heat.

For jaundice with damp-heat, a surging and rapid pulse is favorable; a floating and large pulse is acceptable, but a minute and choppy pulse is difficult to treat.
Jaundice without thirst is treatable; jaundice with thirst is difficult to treat. Absence of pulse at the Cun position near the palm, with cold mouth and nose, indicates death. Jaundice toxin entering the abdomen with wheezing and fullness indicates death.
