The aim of the present systematic review was to evaluate and summarize the available clinical evidence on the anxiolytic effects of aromatherapy during the first stage of labor. Methods: Electronic databases including: Cochrane Library, MEDLINE/ PubMed, Scopus, CINAHL, SID, Iran Doc, ProQuest, and Google Scholar were searched up to Sep10, 2017 with the keywords of 'aroma*', 'aromatherapy', 'essential oil', 'anxiety', and ' labor '. The risk of bias in the included studies was assessed using the Cochrane Collaboration's 'Risk of bias' tool. The results were reported qualitatively. Results: A total of 14 published papers and 2 unpublished papers were retrieved which met the inclusion criteria. The studies were conducted in Iran, Egypt, Korea, and Italy. Essential oils had been used were lavender in 5 articles, rose, clary sage, geranium and frankincense in 3 articles, chamomile, bitter orange, sweet orange and peppermint in 2 articles, mandarin orange, jasmine and clove in 1 article. A majority of the studies suggested a positive effect of aromatherapy in reducing women's anxiety during the first stage of labor. Conclusion: It is recommended that aromatherapy could be applied as a complementary therapy for reducing anxiety during the first stage of labor, but methodologically rigorous studies should be conducted in this area.
