Chinese meridian theory

(chy-NEEZ meh-RIH-dee-un THEER-ee)
In traditional Chinese medicine, meridians are channels that form a network in the body, through which qi (vital energy) flows. Blocked qi causes pain or illness. The flow of qi is restored by using pressure, needles, suction, or heat at hundreds of specific points along the meridians.
