Anti-pain Point

That acupuncture would relieve postsurgical nausea and vomiting was not entirely surprising to researchers at Duke University Medical Center. After all, they were stimulating P6, an acupuncture point near the wrist that is known to control nausea. It's the reason commercial anti-seasickness wristbands work. But the scientists were surprised that the ancient Chinese therapy, applied to the same point using a small electric pulse, also eased pain — perhaps by stimulating the release of endorphins.
