Five element theory is one of the major systems of thought within Chinese medicine. From a historical perspective it is an important underpinning of medical theory and serves as one of the major diagnostic and treatment protocols. In modern clinical practice the five element theory is used in varying degrees depending on the practitioner and style of acupuncture that they practice.
For practitioners or Traditional Chinese Medicine (TCM), the theory may be used to help form a diagnosis when there is conflicting signs and symptoms. Additionally, elements of the theory are useful for assisting patients with nutritional balancing and/or working through emotional issues.
