Acupuncture is a collection of procedures involving penetration of the skin with needles to stimulate certain points on the body. In its classical form it is a characteristic component of traditional Chinese medicine (TCM), one of the oldest healing practices in the world.Stimulating specific acupuncture points corrects imbalances in the flow of qi through channels known as meridians.
Research suggests that traditional forms of acupuncture are more effective than placebos in the relief of certain types of pain and post-operative nausea. Recent systematic reviews found that acupuncture also seems to be a promising treatment option for anxiety, sleep disturbances, and depression.
