“…10 However, results of previous research are mixed for the effectiveness of inhalation via a diffuser in reducing anxiety. Half of available studies found a significant effect on anxiety, 3,4 and the other half 5,9 found no difference. Other factors such as underpowered samples or lack of psychometrically sound tools may also come into play when explaining these insignificant findings.…”

“…Further, the author stated that alpha frequency shows large inter-individual differences which are related to age and memory performances. Motomura et al [15] suggested that the exposure of lavender oil increased the level of theta 1 waves and decreased the level of beta waves.…”

The aim of this work was to determine the chemical composition of essential oil from aerial partsof Mentha arvensis L. f. piperascens (MAO) and to evaluate the effect of its fragrant chemicals on electroencephalographic (EEG) activity of human brain. The MAO was obtained by supercritical CO2 extraction. The maximum yield was 2.38% at conditions of 70ºC and 200 bar. There were 32 volatile chemicals with 6 alcohols (67.11%), 13 hydrocarbons (17.05%), 9 esters (11.50%), 2 ketones (7.16%), 1 oxide (2.77%), and 1 aldehyde (0.56%). The major components were (Z,Z,Z)-9,12,15-octadecatrien-1-ol (50.06%), 2-hydroxy-4-methoxyacetophenone (7.50%), and 3,4-dihydro-8-hydroxy-3-methyl-1H-2-benzopyran-1-one (6.60%). Results of the EEG study showed that inhalation of MAO significantly changed the EEG power spectrum values of relative gamma, relative fast alpha, and spectral edge frequency 90%. During the inhalation of MAO, the value of relative fast alpha was significantly increased (p<0.05). On the other hand, the values of gamma and the spectral edge frequency 90% were significantly decreased (p<0.05). The present study suggests that fragrant chemicals of essential oil of M. arvensis reduce the level of mental stress and that they could be used in the treatment of psychophysiological disorders.

“…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.
