Acupuncture involves the insertion of very thin, sterile, single-use needles into the body to stimulate acupoints. Acupoints are areas on and below the skin's surface where the circulation of the body's energy (Qi, or Chi) can be manipulated.  Acupoints are often located on meridians, or the channels in the body through which energy flows.  The Meridian Theory of Traditional Chinese Medicine is a holistic one - for the best therapeutic results it is important to restore circulation and balance energy not only in the local area where symptoms manifest, but also in the entire body, including the internal organs. Stimulating appropriate acupoints on the arms, legs, trunk and/or head "re-calibrates" the circulation of energy and blood throughout the entire body, resulting in an improved state of health and sense of well-being.
