My training was in classical 5-element acupuncture, which is based on the theory of the 5-elements: Fire, Earth, Metal, Water and Wood. This theory views all of the world, including plants, animals and humans, as well as inanimate objects like rocks, as manifestations of one of the five-elements. Illness is viewed as an imbalance in one or more of the elements. By recognizing the specific signs that relate to each of the elements, the practitioner can identify which element is most in need of attention. Treating this element addresses the root of the problem. Because the functioning of all of the elements is so closely interrelated, treating one element will result in changes to all of them.
