Citrus & Pinellia Formula (Er Chen Tang). This classical formula is the basis for nearly any formula that is used when phlegm-damp is the underlying pattern. It is used when phlegm-damp from the spleen blocks the flow of qi and interferes with the normal functions of the spleen and stomach. It can be used for clear or white, sticky phlegm in the lungs, as well as many problems of the stomach and spleen caused by phlegm-damp. Its primary action is to rectify the qi so that the qi can transform fluids properly.
