痰之为病最烈，痰之为病亦最多。积湿与郁火二者为生痰之大源。其余或因风，或因寒，
或因气，或因食，变怪百出，随感而生，难可枚举。治痰大法，湿则宜燥，火则宜清，风则
宜散，寒则宜温，气则宜顺，食则宜消。二陈汤为治痰之主药，以其有化痰理气、运脾和胃
之功也。学人随症加减，因病而施，则用之不穷矣。

Phlegm pathogens cause the most severe diseases, and phlegm disorders are also numerous. The accumulation of dampness and stagnant fire are the two major sources for generating phlegm. Others may arise due to wind, cold, qi stagnation, or food retention, manifesting in myriad bizarre ways, arising with different pathogenic factors, making it difficult to enumerate them all. The general principles for treating phlegm are: for dampness, drying is appropriate; for fire, clearing is appropriate; for wind, dispersing is appropriate; for cold, warming is appropriate; for qi stagnation, smoothing is appropriate; for food retention, resolving is appropriate. Erchen Tang (Two-Cured Decoction) is the primary formula for treating phlegm because it has the functions of resolving phlegm, regulating qi, strengthening the spleen, and harmonizing the stomach. Students should modify the prescription according to symptoms and apply treatment based on the disease, so that its application will be inexhaustible.
