The meridian theory is the study of the physiological function and pathological change on the meridians, the their related zangfu organs. The essential functions of the meridian system are to "transport qi and blood," "to maintain conductivity" and "to resist invasion of exogenous pathogenic factors." The meridian system distributes to all parts of the body. The endless circulation of qi and blood in the meridians is responsible for the maintenance of life and the variety of functions which support it. The meridian theory has been the guiding principle for the clinical practice in the realms of TCM, particularly in those of acupuncture, massage and qigong. By combining the meridian theory with the theories of the zangfu organs and the etiology of TCM, one can thoroughly explain both the physiological activities and pathological change which take place in the body. In this manner, a theoretical basis for the principle of treatment in accordance with the differentiation of symptoms and sighs was established.
