Acupuncture may be viewed as an ancient art of skin diagnosis and therapy. It is based on the assumption that internal disorders are reflected in changes in certain points of the skin. About a thousand of such points have been mapped through the centuries, each 1 or 2 mm in diameter. These acupuncture points are considered to form groups, each group being arranged along a line, a so-called meridian, which is associated with an internal organ. Each of the 12 basic meridians runs along a major part of the body and terminates at a fingertip or a toe. Meridians, organs, and diseases are distinguished in two groups: Yang and Yin [1].
