To treat a patient who suddenly experiences chills without gradual onset, skin yellowing resembling "qu chen" (fine dust-like discoloration), scanty and painful red urine, intermittent constipation, normal breath, and unimpaired diet. When various decoctions fail to resolve the condition, this formula is prescribed for chronic jaundice.
*Shenkang* (Radix Sophorae Flavescentis), *Huanglian* (Rhizoma Coptidis), *Gua Di* (Fructus Momordicae), *Huangbai* (Cortex Phellodendri, peeled), *Dahuang* (Rhubarb Rhizome, steamed, each 1 fen), *Tingli* (Semen Lepidii/Descurainiae, stir-fried, 0.5 liang).
Grind the above ingredients into a fine powder. Take one large qian per dose, mixed with water. Vomiting and purging are expected outcomes. Adjust dosage according to the patient's condition.

To treat jaundice where urine color is not significantly altered, the patient desires spontaneous defecation, presents with abdominal fullness and wheezing. Heat-clearing methods should be avoided; if heat is removed, hiccups will inevitably occur.
*Xia Ban* (Rhizoma Pinelliae, washed seven times in hot water).
Grind the above ingredient into a coarse powder. Take three qian per dose, with two zhan of water and ten slices of ginger. Decoct until approximately 0.7 zhan remains, strain, and take at any time.

*Yangrong Tang* (Nourishing Prosperity Decoction): Treats five types of jaundice accompanied by lower limb weakness, palpitations, bland taste in the mouth, tinnitus with slight aversion to wind/cold, fever with rapid breathing, and turbid white urine. It should be treated as consumptive disease (Xu Lao). (See Formula Section on Deficiency Damage)

The *Neijing* (Inner Canon) records "Gu Zhang" (Drum Distension), referred to as "Gu Zhang" (Grain Distension) in the *Tai Su*. Although treatment methods are detailed, the etiology is not discussed. Investigating the origin of abdominal distension, it stems from the relationship between the Stomach and Large Intestine (Yangming meridians) and the Spleen and Lungs (Taiyin meridians), which are exterior-interior pairs. Generally, Yin acts as the master, while Yang provides correction. Imbalance of organ qi, involving overcoming (Ke) or insulting (Cheng) relationships, leads to mutual influence and disorder of Yin and Yang, resulting in this syndrome. For instance, anger injures the Liver; Liver wood overcomes Spleen earth. If Spleen qi becomes abnormal, distension occurs in the Stomach, termed "Sheng Ke" (Overcoming); or anger attacks the Lung; if Lung qi fails to transmit, distension occurs in the Large Intestine, termed "Cheng Ke" (Insulting). Grief and worry cause accumulation and stagnation of the affected organ's qi, whether excess or deficiency. Analyzing the involvement clarifies the interior-exterior dynamics, all falling under internal causes. Alternatively, exposure to cold, heat, wind, or dampness transmits via meridians to the Yangming, causing distension, which belongs to external causes. Irregular eating habits, consumption of raw, cold, sweet, or greasy foods leading to accumulation, formation of masses, bloating, and fullness belong to neither-internal-nor-external causes. One must understand that distension involves the Three Causes theory. Differentiate internal and external causes by comparing the Renying and Qikou pulses; assess warmth or purgation needs based on pulse excess or deficiency; regulate carefully without missing key points. Otherwise, it becomes an intractable abdominal or cardiac disease, leading to helplessness and death. Caution is essential.
