I recently watched this 1 hour BBC documentary called "Acupuncture, The Evidence." The narrator is a scientist and travels to China to see what acupuncture is all about. There's really cool footage of an open heart surgery using acupuncture as part of the anesthesia! The patient is conscious the whole time. If that's not your cup of tea, then you can fast forward to part where acupuncture is researched by Western scientists using MRI's. Enjoy!
