Acupuncture is an ancient Chinese healing technique that involves inserting thin needles into specific points on the body. It is based on the belief that vital energy called qi flows through meridians or energy pathways in the body, and inserting needles can restore balance when qi is disrupted. The document traces the history of acupuncture from ancient China to its introduction in Europe and the United States. It also describes related techniques like electroacupuncture, moxibustion, cupping, and acupressure. While research is still being done on how acupuncture works, supporters believe it can help reduce pain and relieve nausea. Potential risks include bleeding or organ damage if done improperly.
