Diet enters the stomach; if the Spleen and Stomach function normally, there is no regurgitation. If Damp-Heat steams and fumes mutually, it forms an Acid Syndrome. Vomiting acidic water is called "Vomiting Acid" (Tu Suan); if vomiting persists with a sensation of rectal prolapse/heaviness, it is recognized as "Swallowing Acid" (Tun Suan). If this condition is not treated, it will gradually worsen into nausea, progressing day by day to Fan Wei (Regurgitation) and Ye Ge (Dysphagia). Vomiting acid occurs because body fluids rise with Qi; after long-term stagnation and accumulation, Damp-Heat becomes severe. It then transforms via Fire (Wood generating Fire), thus becoming sour. This disease belongs clearly to Heat patterns. Swallowing acid results from accumulated heat stored in the internal organs; acidic water is formed and fixed by external Cold binding. External Cold constrains the exterior, making it difficult for pathogens to diffuse outward, causing severe acidity between the Heart and Stomach. Er Chen Tang (Two-Aged Decoction) and Yue Ju Wan (Pill Relieving Depression) are the primary treatments: use Wu Zhu Yu (Evodia Fruit) for Cold patterns, and Lian Lian (Coptis Rhizome, implying Huang Lian) continuously for Heat patterns. Furthermore, avoid anger to calm the Liver; when flavors are light, the Stomach remains pure and clear.
Edema originates from Water, while Distension arises from Qi. Water is divided into Yin and Yang types. Exogenous causes resulting in excess conditions are Yang Edema (Yang Shui). Alternatively, after a major illness, weakness of the Spleen and Lung fails to regulate the Water passages. Or, Heart Fire overacts on Metal (Lung), preventing the Lung from generating Kidney Water, leading to difficult urination. Or, Yin deficiency of the Kidney channel allows Deficient Fire to scorch Lung Metal, reducing urine output. Misuse of Qi-moving and diuretic agents leads to panting, profuse phlegm, and scanty urine, brewing into Edema. These internally originated cases represent deficiency and are Yin Edema (Yin Shui). Human life relies on Water and Grain; the Spleen governs Grain, and the Kidney governs Water. When Water is excessive and Earth (Spleen) is weak, failing to control Water, Water Qi overflows, causing edematous flesh. Shi Pi Yin (Realize the Spleen Decoction) is suitable for Yin Edema (characterized by free bowel movements, no thirst, and swelling); Zhou Che Wan (Boat and Cart Pill) can be recorded for Yang Edema (use with caution). Thirst, red face, Qi obstruction, constipation, and swelling indicate Yang Edema. For upper Wind Edema, Ma Huang (Ephedrae Herba) and Fang Feng (Saposhnikoviae Radix) are essential. For lower Damp Edema, Yi Yi Ren (Coicis Semen) and Fang Ji (Stephaniae Tetrandrae Radix) are sufficient. There are also deficiency patterns distinguishing Qi and Blood: Si Wu Tang (Four Substances Decoction) combined with Si Jun Zi Tang (Four Gentlemen Decoction). Morning ease and evening urgency indicate Blood Deficiency; evening ease and morning urgency indicate Qi Deficiency. Distension preceding panting uses Cang Zhu (Atractylodis Rhizoma) and Bai Zhu (Atractylodis Macrocephalae Rhizoma); panting preceding distension adds Mai Dong (Ophiopogonis Radix) and Fu Ling (Poria). Water swelling generally stems from Damp-Heat accumulation; blockage of the seepage pathways leads to occlusion. Pathogenic Water follows Qi into the collaterals, even reaching lip swelling and umbilical protrusion (lip swelling and umbilical protrusion are death signs). Although it is said that Dampness excess implies Spleen deficiency, the general principle holds that tonifying the Middle Jiao is most beneficial.
