Over the centuries, Traditional Chinese Medicine has mapped out subtle networks throughout the body. When these networks get blocked or depleted, disease occurs. Traditional Chinese Medicine has also identified points along these pathways that control certain actions in the body. The ancient Chinese found that stimulating these points caused a cascade of positive changes. Acupuncture is the practice of inserting fine needles in these precise locations. By doing this, we can unblock the pathways, helping energy and blood to flow smoothly again and directly affecting the body's capacity to heal. Computer imaging has shown that, during an acupuncture treatment, dynamic activity occurs in many regions and structures of the brain. This research has also demonstrated that stimulating an acupuncture point increases the production of endorphins and simultaneously activates the immune and endocrine systems.
