The ancient Chinese believed that there is a universal life energy called Chi or Qi present in every living creature. This energy circulates throughout the body along pathways called meridians. When this energy flows freely, health is maintained, but when the flow of energy is blocked, the system is disrupted and pain and illness occur. Acupuncture works to restore normal function by inserting needles into pre-determined acu-points on the meridians in order to unblock the Qi.
