Acupuncture has been used for over 3,000 years. There are many theories as to how the effects of acupuncture arise. The traditional (Chinese) view is that energy flows freely when the body is in a healthy state. If there is a problem, energy stagnates which leads to pain. The stimulation of appropriate acupuncture points by insertion of a fine needle frees this energy. When stimulating an acupuncture point the brain is stimulated to produce natural pain relieving chemicals called endorphins. These assist the body to heal itself and gain pain relief.
