Acupuncture treats and prevents disease by manipulating the flow of Qi and blood through body channels, known as meridians. These meridians are likened to an invisible aqueduct system that transports life maintaining substances throughout the internal organs, skeletal system, and all other tissues. There are 12 main and 2 extra meridians that irrigate the human body, and along these pathways, close to the skin’s surface, lay the acupoints which act as valves in the system. The acupoints are manipulated to open and clear blockages, or to close and prevent unnecessary draining of substances. In this way, balance is restored and maintained.
