침 (Needle) is a slender, pointed tool used for sewing or stitching fabrics together. Needles come in various sizes and types, each designed for specific materials and purposes. They are typically made of metal or plastic and have a small hole, called an eye, through which thread is passed. In traditional medicine, particularly in 한의학 (Korean medicine), 침 (acupuncture needles) are used to stimulate specific points on the body. This practice aims to promote healing and balance within the body. Acupuncture is a key component of 한방 (traditional Korean medicine) and is believed to help alleviate pain and improve overall health.
