Acupuncture
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), a form of alternative medicine, and one of the oldest healing practices in the world.[1] According to traditional Chinese medicine, stimulating specific acupuncture pointscorrects imbalances in the flow of qi through channels known as meridians.[2]
