Chung KF, et al. - This randomised, assessor-blinded, waitlist-controlled trial was conducted to test the superiority of acupuncture plus auricular acupuncture (combination treatment) over acupuncture alone for insomnia. In this work, safety and mild hypnotic effects of acupuncture and combination treatment were reported, which lasted for at least 13 weeks. Limited by short-term treatment and follow-up, the attempt to augment acupuncture by auricular acupuncture was not supported.
