The National Institutes of Health (NIH) has concluded that acupuncture starts the flow of pain-relieving endorphins and immune system cells to specific sites in the body that are injured or vulnerable to disease. Both the World Health Organization (WHO) and the NIH acknowledge the benefits of acupuncture for treating and eliminating pain due to a wide range of causes. Stress-related disorders, pain management, and chronic disease are three of acupuncture medicine’s specialties.
