Meridian therapy is to treat the symptoms and syndromes of meridians by the points on the meridians involved, and the selection of treatment points is based upon the distribution and inter-relationships of meridians. Syndromes of meridians form the major contents of meridian therapy, among which are the syndromes of twelve master meridians, the eight meridian syndromes, and the linking meridian syndromes. When the symptom of a meridian involes only one meridian, the points on that meridian may be selected for treatment. When the symptom involves two or more meridians, the points on those meridians may be selected for treatment. When the points on two or more different meridians are to be selected for treatment, the points on the deep-superficial meridians, the points on the hand-foot meridians, and the points on the connecting meridians may be selected. When the symptom under treatment involves two or more internal organs, it may be treated by the meeting-points of meridians. There are close to 100 meeting-points of meridians, some of them are meeting-points of two meridians while others of them are meeting-points of three or four meridians.
