Abstract: Through compiling and studying the related literature of Jinshui Liujun Decoction, we find that this formula is created based on Erchen Decoction and Zhenyuan Yin. Especially in drying dampness and dissolving phlegm aspects, rehmanniae radix praeparata and angelicae sinensis radix are added into it to warm and supplement genuine yin for treating deficiency-cold, highlighting the formulation idea of tonifying original qi, as well as warming the spleen and strengthening the kidney. In addition, this formula was used by Zhang Jingyue for treating 19 kinds of diseases and syndromes, and it was also widely used by later generations of physicians with flexible modifications. Therefore, the study on the medicine compatibility characteristics and the formulation idea of Jinshui Liujun Decoction is of great practical value and guidance for the later generations to understand Zhang Jingyue's harmonization treatment method, to study his academic idea of warming and supplementing genuine yin, and to broaden the clinical ideas of treating phlegm along with panting syndrome.
