Acupuncture is an ancient Chinese practice that involves inserting thin needles into specific points on the body. It originated in China over 2000 years ago and has since spread throughout East Asia and other parts of the world. The theory behind acupuncture is that it works by stimulating the body's meridian lines and energy flow. Needles are inserted into acupuncture points to relieve pain and treat various disorders by altering patterns in a person's energy system. Acupuncture can help treat conditions like neck pain, headaches, arthritis, infertility, and stress-related issues.
