Traditional Chinese Medicine (TCM) originated in China, rooted in ancient Chinese culture and philosophy. Its development can be traced back thousands of years, deeply embedded in ancient Chinese understandings of nature, life, and the universe. The development of TCM is inseparable from ancient Chinese philosophy, especially Daoism and Confucianism. These schools of thought emphasize harmony between humans and nature, the balance of Yin and Yang, and the theory of the Five Elements, all of which form the foundational principles of TCM. Our clinic's Chinese name is "炁度" (Qì Dù). In TCM theory, "炁" (Qì) is one of the core concepts, referring to an invisible yet perceptible life energy that permeates the entire body, sustaining life activities and physiological functions. The flow and distribution of Qi directly affect a person's health. "度" (Du) in TCM refers to "assessing Yin and Yang," which involves predicting and analyzing changes in these forces. Yin and Yang describe two opposing yet interdependent forces, such as cold and heat, internal and external, deficiency and excess. Yin and Yang are fundamental in TCM theory, involving two basic energies—Yin and Yang. These two energies oppose and complement each other, working together to maintain life activities and the dynamic balance of nature. In TCM, the concept of Yin and Yang permeates all areas, including physiology, pathology, diagnosis, and treatment. Yin and Yang are the origin of life and the driving force behind all changes. The balance of Yin and Yang is the foundation for explaining physiological and pathological phenomena. Through "assessing Yin and Yang," TCM practitioners evaluate the balance of internal and external Yin and Yang, as well as the pathological changes caused by imbalances. This process is at the core of TCM diagnosis and treatment, reflecting the essence of TCM's dialectical approach.
