There’s mixed evidence on the efficacy of acupuncture for major depressive disorder, and very little research on the efficacy and safety of acupuncture for PPD. Safety is a somewhat greater concern for acupuncture than for other non-pharmacological therapies, because some acupuncture points reportedly hasten labor. In three studies of acupuncture for PPD, two studies found greater efficacy than control (sham) acupuncture, but the third did not.[1]
