The *Neijing* states: Those with yellow-red urine and excessive sleepiness suffer from Huangdan (Jaundice).
The *Jingui Yaolue* states: The pulse at Cun Kou (radial artery) is floating and slow. Floating indicates wind; slow indicates bi-syndrome (obstruction). This bi-syndrome is not wind-stroke, but rather discomfort in the four limbs. The color of the spleen (yellow) must appear, and stagnant heat circulates. A floating pulse at Chi position indicates kidney injury. A tight pulse at Fu Yang position indicates spleen injury. Wind and cold contend; after eating, dizziness occurs, food is not digested, the stomach suffers from turbid qi, which flows downward, causing urinary obstruction. Yin-cold invades, and heat flows into the bladder, turning the whole body yellow; this is called Gu Dan (Grain Jaundice). Blackness on the forehead, slight sweating, heat in hands and feet, onset in the evening, bladder urgency, and difficult urination constitute Nu Lao Dan (Female Labor Jaundice). Abdomen distended like water accumulation, mental restlessness and heat, inability to eat, frequent desire to vomit constitute Jiu Dan (Wine Jaundice); these are mostly incurable.
The *Mai Jing* states: Deep pulse, thirst with desire to drink, and difficult urination all lead to yellowing. For all jaundice cases, if the pulse near the palm at Cun Kou is absent, and the nose and mouth are cold, it is incurable.

Chen Wuyue stated: The ancient formulas describe five types of jaundice, but they are essentially one disease with different names. For example, Huang Han (Yellow Sweat): The stomach is the exterior of the spleen, belonging to the Yangming channel. Yangming accumulates heat, predisposing to spontaneous sweating. After sweating, entering water causes heat to stagnate, thus the sweat turns yellow. Later, the body swells, fever occurs without thirst, resembling Feng Shui (wind-water edema) syndrome. Sweat stains clothes yellow like pagoda tree juice.
Huang Dan (Jaundice): Caused by sudden heat followed by bathing in cold water, trapping heat in the stomach. Symptoms include yellowing of the body, face, and eyes like gold, and urine like boiled pagoda tree juice.
Gu Dan (Grain Jaundice): Caused by skin fever and overeating damaging stomach qi, leading to counter-flow stagnation. Symptoms include abdominal fullness and dizziness after eating, and failure to digest grain qi (see previous text).
Jiu Dan (Wine Jaundice): Caused by heavy intoxication while exposed to wind or entering water. Wine produces many variations; heat toxin flows into the clear qi pathways, causing yellow eyes and nasal carbuncles.
Nu Lao Dan (Female Labor Jaundice): Caused by sexual intercourse during extreme heat followed immediately by entering water. Water-dampness enters the spleen due to severe kidney qi deficiency. The overcoming element attacks, causing kidney qi to ascend, resulting in black forehead and yellow body.
Cases with both thirst and abdominal distension are difficult to treat. Disease originating in Yin leads to vomiting; disease originating in Yang leads to chills and slight facial heat. Although rooted in stomach qi stagnation and the upward display of earth color, if it originates in the spleen, it is internal jaundice; if in the kidney, it is black jaundice. Regarding etiology, external factors include wind, cold, summer-heat, and dampness; internal factors include joy, anger, worry, fright, wine, food, and sexual fatigue. All three categories of causes are present. Physicians strictly adhere to the *Shanghan Lun* (Treatise on Cold Damage) but neglect these aspects, which is overly broad.
Note: The above five types of jaundice differ from those listed in the earlier *Jingui Yaolue*; they should be studied concurrently. Chen’s treatment examples do not exhaust the variations. Investigating the pathology and treatment, the manifestations of the five jaundices are complete. For combined symptoms, Huang Han, Huang Dan, and Gu Dan should primarily be treated by supporting Yuan Qi (Original Qi) and Spleen-Stomach qi. If physical constitution, Zheng Qi (Upright Qi), and Gu Qi (Grain Qi) are slightly substantial, recovery is possible. In Jiu Dan, Yuan Qi and Stomach qi are severely damaged, leaving physical constitution and Zheng Qi isolated and precarious. Mixing grain intake with medication makes survival rare, requiring abstinence from rich flavors and strict adherence to medication. In Nu Lao Dan, Yin and Yang qi are exhausted, making severe cases difficult to treat. Chen stated that physicians strictly focus on Shanghan but ignore this condition; this is indeed beyond the scope of standard Shanghan methodology.
