According to traditional Chinese medicine, acupuncture is a method for regulating the flow of chi or qi (chee), which is thought to pass along meridian pathways in your body. Acupuncturists believe that by placing needles into particular locations along these meridians, your energy flow will be restored to equilibrium.
Many Western practitioners, in contrast, see the acupuncture points as locations to activate muscles, connective tissue, and nerves. According to some, this stimulation increases your body’s natural painkillers.
