Health represents a balance of the yin and the yang while disease is due to the disharmony between these two opposing forces. The balance of these two forces within the body is manifest in the flow of energy called chi. This represents the life force that flows through the body in precise and orderly patterns called meridians. Chinese medicine identifies fourteen meridians, twelve of which are associated in maintaining individual organ function while two are responsible for unifying various systems. If the meridian is blocked or stagnant, an imbalance of the life force is created, resulting in disease or abnormalities.
Treatment is based in bringing harmony between the yin and the yang.
These include the use of certain food, herbs, tai chi exercises, acupuncture, acupressure, application of heat, or massage. It is use to restore balance between the yin and the yang. It is used both as a diagnostic tool to detect imbalance of the life force and a way to treat diseases. The needle is inserted just below the epidermis and does not draw blood or cause discomfort. Heat is sometimes applied to the acupuncture sites, a technique called moxibustion.
