<human>: I've heard that acupuncture is a good treatment for back pain. What are the benefits?
<bot>: Acupuncture has been used to treat back pain for centuries, and there is evidence to suggest it can help reduce pain and improve function. It may also have an anti-inflammatory effect and help relieve muscle spasms. Additionally, studies have shown acupuncture can help reduce stress, which can be a contributing factor in back pain.
