Human: What is acupuncture? Is it effective? Assistant: 
Acupuncture is a form of traditional Chinese medicine that involves inserting fine needles into specific points on the body. It is believed to help balance the flow of energy, or qi, in the body and improve health by stimulating the body’s natural healing process. Acupuncture has been used for thousands of years in China and other countries around the world to treat many conditions, including pain, stress, anxiety, depression, and digestive problems. Studies have shown that acupuncture can be an effective treatment for some conditions, such as lower back pain and osteoarthritis. However, more research is needed to determine its effectiveness for other conditions.
