Western medicine cannot yet completely explain how acupuncture works. But more and more research is being conducted that confirms the effectiveness of the action of the points. In some studies, magnetic imaging has shown changes in the brain when certain points are stimulated. We do know that acupuncture improves circulation, reduces inflammation and can boost the immune system. Acupuncture has a powerful effect on both the sympathetic and parasympathetic nervous systems, and hence can regulate the whole body.
