The theory of five elements is an ancient philosophical thought that studies the concept, characteristics, and laws of the five elemental energies of wood, fire, earth, metal, and water. The five-element theory is used to explain the occurrence, development, change, and interrelationship of everything in the universe.
Traditional Chinese medicine (TCM) applies the theory of five elements to the medical field, and also uses it to explain the organic connection between different body parts and the whole body, the body surface and the internal organs, as well as the union of the human body and the external environment.
