Cochrane systematic reviews examine P6 acupuncture-point stimulation for nausea and vomiting

Reviews were found on postoperative sickness, chemotherapy-induced nausea and vomiting, and pregnancy-related nausea and vomiting. Results for postoperative nausea and vomiting show the most consistent results with showing the superiority of stimulation over sham and for both nausea and vomiting. Stimulation seemed to be superior to antiemetic medication for nausea and equivalent for vomiting. Results for chemotherapy-induced nausea and vomiting showed that electroacupuncture, but not manual acupuncture, was beneficial for first-day vomiting. Acupressure was effective for first-day nausea but not vomiting. Results for pregnancy-related nausea and vomiting were mixed.
