Acupuncture is practiced based on an energetic model rather than the biochemical model of Western medicine. The ancient Asian recognized a vital energy Qi(pronounced chee). In developing an understanding of the prevention and cure of disease, these healing practitioners discovered that this energy flows along specific pathways called “meridians”. Each pathway is associated with a particular physiological system and internal organ. Disease is considered to arise due to a deficiency or imbalance of energy in the meridians and their associated physiological systems. Acupuncture points are specific locations along the meridians. Each point has a predictable effect upon the vital energy passing through it. Modern science has been able to measure the electrical charge at these points, thus corroborating the locations of the meridians mapped by the ancients.
