Acupuncture is a form of traditional Chinese medicine that involves the insertion of fine needles into specific points on the body called acupoints. The practice is based on the belief that there are energy pathways (or meridians) that run through the body, and that blockages in these pathways can cause illness or discomfort. The insertion of needles at acupoints is thought to stimulate the flow of energy, or "qi," and restore balance to the body, thereby promoting physical and emotional well-being. Acupuncture is often used to treat a wide range of conditions, including chronic pain, headaches, anxiety, and depression, among others.
