ABSTRACT
According to the traditional Chinese medicine(TCM) theory, Qi is the essential component maintaining life. Mitochondria are the cellular organelles that generate energy. Qi exhibits abundant common characteristics in bioenergetics compared with mitochondria which control the cellular energy through fusion and fission. Studies have proven that the qi-tonifying function of Chinese medicinal plants and their components facilitates mitochondrial fusion, therefore enhancing ATP synthesis. These studies provide a framework for deciphering the pharmacological mechanisms of Qi-tonifying herbs. This article introduces the common source and function shared by Qi and mitochondria and the regulatory effects of herbal remedies on energy from mitochondria dynamics. This review aims to interpret the connotation of tonifying qi in TCM theory based on the modern biomedical theory.
