the Essential Role of Zheng Qi in Promoting Health: From the Perspective of Chinese Medicine and Modern Medicine

引用

Chinese Medicine 2024年第2期15卷 27-33页

作者： Kam Ming Ko hoi Yan leung Division of Life Science Hong Kong University of Science & Technology Hong Kong SAR China

the concept of Zheng Qi in traditional Chinese medicine (tCM) refers to the vital energy produced by the interaction of Yin and Yang forces in the body. Zheng Qi performs two main functions: Wei Qi (defensive Qi), which shields the body from external pathogens, and Ying Qi (nutritive Qi), which sustains the internal organs and enhances their functionality. In tCM, Chinese tonifying herbs can help restore the balance of Yin/Yang and Qi/Blood function in visceral organs (i.e., optimal physiological functions), thereby fostering the efficient production of Zheng Qi and enhancing health. to ensure the quality of Chinese herbal products, functional assays to measure Yin/Yang, Qi/Blood functions, and Zheng Qi production should be implemented. the efficacy of Yang and Qi herbs can be evaluated by their ability to increase mitochondrial AtP in cultured mouse cardiomyocytes, while Yin and Blood herbs are tested through their immunostimulatory effects on antigen-induced t/B cell proliferation in mouse splenocytes and the production of erythropoietin/nitric oxide in hepatocytes/vascular endothelial cells, respectively. Additionally, Zheng Qi’s effect can be gauged by examining natural killer cell activity and antigen-induced t/B cell proliferation in mice ex vivo. these assays act as biomarkers for assessing the quality and effectiveness of herbal health products within tCM theory.
