We thank Freedman et al1 for their letter in regard to our randomized trial comparing nausea relief with aromatherapy versus oral ondansetron. We found that patients allocated to arms receiving aromatherapy reported greater nausea reduction at 30 minutes.2 This finding adds to the growing literature demonstrating that aromatherapy has efficacy in treating nausea in the emergency department (ED) setting.3 That said, Freedman et al1 highlight several important study limitations.
