Background and purpose: Vasomotor symptoms (VMS) are very common in menopausal populations and cancer patients and can cause physical and mental discomfort. We aim to summarize the findings of systematic reviews and meta-analyses (SRs/MAs) that assessed the effectiveness of complementary and alternative medicines (CAMs)on VMS to provide solid evidence for future practice. Methods: PubMed, Embase, the Cochrane Library, and Web of Science were searched from inception to May 2019 to identify relevant SRs/MAs. The methodological quality of SRs/MAs and evidence levels of the outcomes were assessed. Results: A total of 29 SRs/MAs were reviewed. Evidence has shown that acupuncture, hypnosis, paced respiration, cognitive behavioural therapy, genistein, soy isoflavones, S-equol, combined preparations of black cohosh, and omega-3 supplements could significantly reduce VMS. The methodological quality of the SRs/MAs was moderate or high. Conclusion: CAMs might be beneficial for reducing VMS, but the evidence levels were not high. Several priorities for future practice were identified.
