How does acupuncture work?

According to ancient Chinese medical philosophy, disease is the result of an imbalance or blockage of energy or energy flow (Qi, pronounced “chee”) in the body. Acupuncture is believed to balance this energy or enhance its flow and thereby assist the body to heal disease. In Western terms, acupuncture can assist the body to heal itself by affecting certain physiological changes. For example, acupuncture can stimulate nerves, increase blood circulation, relieve muscle spasm, and cause the release of hormones, such as endorphins (one of the body’s pain control chemicals) and cortisol (a natural steroid).
