Acupuncture involves using fine needle insertion and manipulation to stimulate certain points in carefully chosen Meridians.  The philosophical theory defines health in TCM based on holistically, that is, whole person is a balance system, balance between physical emotional, and spiritual. Furthermore, humans and natural environment are also considered into a system, and disharmony among these systems might cause illness and semi-health (that cannot be defined by using conventional medical examination and laboratory tests). Acupuncture treatment helps strengthening the body’s own defenses and restoring all system’s balances.
