Human: I've heard that a certain kind of acupuncture can help cure headaches. How does it work? Assistant: 
Acupuncture is a form of traditional Chinese medicine. It involves inserting thin needles into the skin at specific points on the body. These points are believed to correspond to different organs and systems in the body, including the head and neck. The theory behind acupuncture is that by stimulating these points, the energy flow throughout the body can be improved, which may help reduce pain and other symptoms associated with headaches.
