Acupuncture is an ancient technique in which a skilled practitioner inserts hair-thin needles into specific points on the body to prevent or treat illness. Practiced for over 2,500 years in China, where it originated, acupuncture is part of the holistic system of traditional Chinese medicine (TCM), which views health as a constantly changing flow of energy, or qi (pronounced “chee”). In TCM, imbalances in this natural flow of energy are thought to result in disease. Acupuncture aims to restore health by improving the flow of qi.
