Acupuncture involves the insertion of extremely thin needles through your skin, to various depths at strategic points on your body. Acupuncture originated in China thousands of years ago. The traditional Chinese theory behind acupuncture as medical treatment is very different from that of Western medicine. In traditional Chinese medicine, health results form a harmonious balance between the complementary extremes (yin and yang) of the life force known as qi or chi. In contrast, the Western explanation of acupuncture incorporates modern concepts of neuroscience. Many practitioners view the acupuncture points as places to stimulate nerves, muscles and connective tissue. This stimulation appears to boost the activity of your body’s natural painkillers and increase blood flow.
