“…14 The literature search for the current study used PubMed and CISCOM databases and identified eight randomized controlled trials using aroma alone compared to placebo. [15][16][17][18][19][20][21][22] These studies varied greatly in subject numbers (4-313) and had poorly described methods. None evaluated the blinding of the placebo/control intervention (or equipoise) in relation to odor.…”

Background: Insomnia is the most common of all sleep complaints and is under-researched. The current treatments of choice are conventional hypnotics agents, but these have potential for serious adverse reactions. Uncontrolled and anecdotal evidence suggests that lavender oil is an effective treatment for insomnia, but this has not been formally investigated.Objectives: The aims of this study were to evaluate the proposed trial methodology and the efficacy of Lavandula augustifolia (lavender) on insomnia.Interventions: Interventions consisted of Lavandula augustifolia (treatment) and sweet almond oil as placebo/control. The aroma was supplied via an Aromastream device (Tisserand Aromatherapy, Sussex, UK).Design: This was a pilot study with randomized, single-blind, cross-over design (baseline, two treatment periods, and a washout period, each of 1 week duration).Subjects and setting: Volunteers with defined insomnia treated on a domiciliary basis participated in the study.Outcome measures: Outcomes were assessed with the following: Pittsburgh Sleep Quality Index (PSQI) indicating insomnia (score Ͼ5 at entry); Borkovec and Nau (B&N) Questionnaire evaluating treatment credibility; and Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) assessing attitudes to CAM and health beliefs.Results: Ten (10) volunteers (5 male and 5 female) were entered and completed the 4 week study. Lavender created an improvement of Ϫ2.5 points in PSQI (p ϭ 0.07, 95% CI Ϫ4.95 to Ϫ0.4). Each intervention was equally credible and belief in CAM did not predict outcome. Women and younger volunteers with a milder insomnia improved more than others. No period or carry-over effect was observed. Conclusion:The methodology for this pilot study appeared to be appropriate. Outcomes favor lavender, and a larger trial is required to draw definitive conclusions.

“…Despite this fact, it has also been demonstrated that placebo can be as effective as aromatherapy in relieving postoperative nausea. 15 Thus, the beneficial effect observed in the current study can potentially be, at least in part, from the placebo effect.…”

“…18 Aromatherapy with the use of peppermint oil has been rapidly promoted as a remedy for morning sickness, dyspepsia, and other gastrointestinal complaints. 19 Inhalation of peppermint oil vapor has also been shown to be a significant and effective initial complementary therapy for the reduction of postoperative nausea. [17][18][19][20] In a randomized double-blind placebocontrolled study, Anderson and Gross 19 used peppermint-scented pads (0.2 mL of essential peppermint oil with 2 mL of isotonic saline) and IPA (1 mL of 70% IPA on 2 stacked 2 ϫ 2-inch gauze pads) with 2 mL of isotonic saline as the placebo.…”
