Diarrhea is mostly caused by damp-heat. Dongxie (profuse diarrhea with watery stools) is like water bursting from a canal, flowing away without retention, which indicates dampness combined with heat; Huoxie (fire diarrhea) involves abdominal pain and an immediate urge to defecate, or undigested food in the stool (referred to as "pathogenic fire failing to digest grains"), which indicates heat combined with dampness. It often arises from summerheat and food stagnation, or cold invading the abdomen during sleep at night, causing fire to be constrained internally. The treatment method requires clearing heat, promoting urination to leach out dampness, and aiding digestion using aromatic spleen-arousing herbs such as Huangqin (Scutellariae Radix), Hei Zhi (Gardeniae Fructus processed with bran), Jiao Baishao (Paeoniae Radix Alba processed), Fuling (Poria), Zexie (Alismatis Rhizoma), Zhuling (Polyporus), Shan Zha Rou (Crataegi Fructus), Shenqu (Massa Medicata Fermentata), Chenpi (Citri Reticulatae Pericarpium), Guya (Setariae Fructus Germinatus), Houpo (Magnoliae Officinalis Cortex), and Sharen Qiao (Amomi Fructus pericarpium), selected according to symptoms. If heat is severe and undigested food is present, Huanglian (Coptidis Rhizoma) should be used heavily; treating dampness without promoting urination is not the correct approach. However, there are cases where wind is injured in spring, leading to Sunxie (diarrhea with undigested food) in summer. This is because wind belongs to Wood, and Wood overacts on Earth (Liver Wood overacting on Spleen Earth), so it is appropriate to add wind-dispersing herbs such as Fangfeng (Saposhnikoviae Radix), Gegen (Puerariae Lobatae Radix), Qianghuo (Notopterygii Rhizoma et Radix), Chaihu (Bupleuri Radix), and Bohe (Menthae Haplocalycis Herba). Only when damp-heat has subsided but the condition persists for a long time should one tonify the Spleen and Stomach using Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder). Furthermore, diarrhea occurring at the fifth watch (early morning) is due to Kidney deficiency, treated with Sishen Wan (Four Spirits Pill).

This syndrome often results from summerheat injuring food intake, or exposure to cold and chill. When Wei Qi (Defensive Qi) responds to the Stomach, if Wei Qi fails to circulate freely, Stomach Qi also becomes obstructed, resulting in simultaneous abdominal pain, vomiting, and diarrhea. Treatment should involve releasing the exterior and harmonizing the Stomach, resolving food stagnation and promoting dampness drainage, while clearing summerheat simultaneously. Herbs include Xiangru (Elsholtziae Herba) (can be used if aversion to cold is present), Banxia (Pinelliae Tuber), Fuling (Poria), Chenpi (Citri Reticulatae Pericarpium), Gancao (Glycyrrhizae Radix et Rhizoma), Chao Baizhu (Atractylodis Macrocephalae Rhizoma stir-fried), Biandou (Dolichoris Semen), Shenqu (Massa Medicata Fermentata), Shan Zha Rou (Crataegi Fructus) (can be used for food stagnation), Houpo (Magnoliae Officinalis Cortex), Huangqin (Scutellariae Radix), Hei Zhi (Gardeniae Fructus processed with bran), and Guang Huo (Magnoliiae Officinalis Cortex / Magnolia Bark, specifically referring to Guang Huo Xiang here contextually though listed as Guang Huo, likely implying Guang Huo Xiang/Aucklandiae Radix or similar aromatic damp-resolving herb, standard translation for 广霍 usually refers to Guang Huo Xiang Petiveriae Herba or similar, but strictly 广霍 is often shorthand for 广藿香 Pogostemonis Herba in clinical notes. I will use Pogostemonis Herba (Guang Huo Xiang) for clarity as it fits the formula profile of Huo Xiang Zheng Qi San derivatives). *Correction*: The text says "Guang Huo", typically short for Guang Huo Xiang. I will translate as Pogostemonis Herba (Guang Huo Xiang). Selected according to symptoms. For those with muscle cramps (Zhuanjin), it involves wind, cold, and dampness, with the disease located in the Liver; one must distinguish the cause and add symptomatic herbs. In the early stage of Huoluan (cholera-like syndrome) with chest tightness and abdominal pain, grain food must be strictly avoided; ignorance of this can lead to death. Therefore, if one feels slightly unwell, it is better to remain fasting; after stability, consume a little thin porridge and gradually increase intake, which is also a method of health preservation.

In ancient times, there were five types of Jaundice (Dan), distinguished into Yin Jaundice and Yang Jaundice. What I have observed includes yellowing of the whites of the eyes, yellow skin, and urine staining white trousers like cypress juice, accompanied by chest tightness, abdominal distension, limb weakness, and lethargy. The etiology is steaming of constrained fire and dampness, primarily treated in the Liver and Stomach meridians, traditionally called Jaundice formed by damp-heat. Damp-heat in the Stomach causes fullness, poor appetite, and abdominal distension; limb weakness (as the Stomach governs the four limbs); and lethargy due to impaired Spleen Qi transportation (as the Spleen and Stomach are interior-exterior paired organs), with constrained fire preventing the free flow of Liver Wood. The treatment method should use wind herbs to overcome dampness, bitter herbs to drain heat, assisted by herbs that open depression and promote drainage, such as Chaihu (Bupleuri Radix), Bohe (Menthae Haplocalycis Herba), Fangfeng (Saposhnikoviae Radix), Gegen (Puerariae Lobatae Radix), Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Xiakucao (Prunellae Spica), Shanzhi (Gardeniae Fructus), Yujin (Curcumae Longae Radix), Chenpi (Citri Reticulatae Pericarpium), Cangzhu (Atractylodis Rhizoma), Yinchen (Artemisiae Scopariae Herba), Fuling (Poria), Yiren (Coicis Semen), Mutong (Akebiae Caulis), Xiangfu (Cyperi Rhizoma), Tongcao (Tetrapanacis Medulla), Shan Zha Rou (Crataegi Fructus), Shenqu (Massa Medicata Fermentata), and Zhike (Aurantii Fructus Immaturus), selected according to symptoms. The five Dan syndromes affect the five Zang organs respectively, but generally do not exceed the methods of dispersing with wind,渗ing (percolating/diuresing) with bland taste, draining with bitter taste, and opening with aromatic taste. Yin Jaundice is described as having a yellow skin color that is dull and stagnant; Yang Jaundice is bright and lustrous. Yang Jaundice can be cured in a few doses, whereas Yin Jaundice cannot be resolved immediately. Individuals who drink alcohol and become angry are most prone to developing this syndrome.
