Acupuncture works by using needles to access the Qi (pronounced "chee") or vital energy at acupoints, and manipulating that energy in specific ways. One can either supplement, drain, or move the Qi in order to restore the proper flow of energy
through the meridians (pathways for Qi) in the body. Meridians are similar to rivers or little energy highways in the body. They are all interconnected and correspond to specific organ systems and flow in designated directions.
Whenever Qi is stuck in a specific area, something happens like a logjam in a river or a traffic jam on a highway, and that part of the body will react, becoming painful or manifesting signs of pathology in an area associated with its correspondent
organ system. Similarly, when there is not enough Qi flowing in a certain meridian, symptoms such as weakness and fatigue may occur, signaling that not enough nourishment is being circulated to all or part of the body. Or if the energy goes
the wrong way in a meridian, like an errant car traveling the wrong way down a one way street, other types of imbalance will arise.
