The five elements are wood, fire, earth, metal, and water. This theory has been used in Chinese medicine diagnosis as early as the "Warring States Period (476-221 BC)" in ancient China.
In order to explain the integrity and complexity of the human body, Chinese medical scientists and physicians use the Five Elements Theory to classify the body's endogenous effects on organs, physiological activities, pathological reactions, and environmental or exogenous effects. Each element is associated with a different network of organs, colors, emotions, tastes, and sensory organs. This provides a multi-dimensional view of your internal organs and helps doctors identify imbalances.
