Abstract: Membrane-source (pleurodiaphragmatic interspace) is an important location for the onset of epidemic disease in the body, and Dayuan Yin (Membrane-source Decoction, DYY) a typical formula indicated for the disease. However, the clinical application of the formula is limited by its acrid-warm and drying nature. Based on original texts from Wenyi Lun (Treatise on Warm-Heat Pestilence) published in the Ming Dynasty, as well as understanding by physicians in later generations, this article discusses the essence of membrane-source and proposes that DYY is indicated for critical condition caused by pattern of dampness trapping hidden deep-lying heat in the middle energizer. As epidemic disease is highly infectious with sudden onset and high mortality rate, first priority in its treatment should be dispelling pathogens hidden inside the human body. Owing to its acrid-warm and drying property, DYY can soothe and drain the membrane-source and transform the dampness-heat pattern into pure heat pattern, which corresponds to the idea of defeating the pathogen by transmitting and changing it proposed by Wu Youke, a famous Chinese epidemiologist and the author of Wenyi Lun. Such practice is still in line with the therapeutic principle of dispersing and purging pathogens through different channels separately in the treatment of dampness-heat pattern. Meanwhile, it is also proposed that the treatment of warm epidemic disease should always center on the pathogens. Besides, the indications of DDY are summarized. Finally, the theoretical significance of membrane-source and DDY is discussed in the current fight against the novel coronavirus pneumonia, also known as the coronavirus disease 2019 (COVID-19).
