A total of 93 participants were divided into a control group (CG) and an experimental group (EG), with 47 participants in the EG receiving MPEO aromatherapy and 46 in the CG. Anxiety levels were measured using the State-Trait Anxiety Inventory (STAI) at pretest and posttest phases. Results: GC-MS analysis showed that menthol had the highest concentration (42.56%), followed by menthone (19.24%) and linalool (11.68%). Mixed model analysis revealed that group assignment (EG vs. CG) was a significant predictor of posttest state anxiety (F=16.508, p=0.001) and trait anxiety (F=9.091, p=0.003), independent of pretest scores, supporting the intervention’s effect on reducing anxiety. Posttest results showed a significant reduction in state anxiety in the EG compared to the CG (p=0.001) with a large effect size (r=0.508), while trait anxiety showed a moderate reduction (p=0.001, r=0.342).&lt;strong&gt; Conclusion: &lt;/strong&gt;These findings suggest that &lt;em&gt;Mentha piperita&lt;/em&gt; essential oil may effectively reduce state and trait anxiety, with a more pronounced impact on state anxiety.&lt;/p&gt;

Certain essential oils are recognized for their potential to alleviate anxiety symptoms. This research was conducted to evaluate the effects of &lt;em&gt;Cymbopogon citratus &lt;/em&gt;essential oil on anxiety. &lt;strong&gt;Methods: &lt;/strong&gt;The chemical composition of the extracted essential oil was analyzed using Gas chromatography with flame-ionization detection (GC-FID) and Gas chromatography-mass spectrometry (GC–MS). In addition, an experimental study with measures at pretest-posttest was conducted, where 128 participants were divided into two groups, a waiting-list (WL) control group, and an experimental group (EG)treated with aromatherapy based on &lt;em&gt;Cymbopogon citratus&lt;/em&gt; essential oil. The anxiety index was evaluated by Zung Self- Rating Anxiety Scale (SAS).&lt;strong&gt; Results: &lt;/strong&gt;The chemical analysis identified geranial (52,1%) and neral (35,2%) as the principal constituents. Anxiety levels decreased in the experimental group during the posttest phase (p&amp;lt;0.05). Besides a large effect size was found for anxiety (d = 0.962; Δ= 0.988) with 1-β=0.999 a percentage of change of -10.99%. &lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;Cymbopogon citratus&lt;/em&gt; essential oil inhalation showed to be effective in decreasing scores anxiety. Therefore, it has the potential to serve as a supplementary treatment for anxiety.&lt;/p&gt;

Furthermore, a quasi-experimental study was conducted, where 81 participants were divided into two groups, comprising a waiting list control group and an experimental group treated with essential oils. Anxiety and depression indexes were evaluated using the Zung Self-Rating Anxiety Scale (SAS) and the Zung Self-Rating Depression Scale (SDS), and sleep quality was measured with the Pittsburgh Sleep Quality Inventory (PSQI). &lt;strong&gt;Results:&lt;/strong&gt; Chemical analysis showed that 1,8 cineole (37.6%), α-pinene (19.9%), and linalool (15.8%) were the main components. Anxiety, depression, and sleep quality scores showed a decrease in the post-test study phase compared to the pre-test in the experimental group (p&amp;lt;0.05). A large size effect was found in the case of anxiety (d = 1.491; g= 1.490) with 1-β=0.996, while medium size effects were observed for depression (d = 0.581; g= 0.582) with 1-β=0.585; and sleep quality (d = 0.586; g = 0.588) with 1-β=0.638. &lt;strong&gt;Conclusion: &lt;/strong&gt;Essential oils extracted from &lt;em&gt;Rosmarinus officinalis&lt;/em&gt; are more effective in calming anxiety and show moderate changes in depression and sleep quality.&lt;/p&gt;

In this sense this study was conducted to examine the anxiolytic-like effect of Luma chequen essential oil. &lt;strong&gt;Methods: &lt;/strong&gt;The essential oil was extracted by steam distillation and the chemical composition was investigated by Gas chromatography with flame-ionization detection (GC-FID) and Gas chromatography-mass spectrometry (GC–MS). Moreover, a randomized, double blind, placebo-controlled trial was conducted, where 48 participants were divided into two groups, comprising a control group (CG) treated with placebo, and an experimental group (EG) treated with aromatherapy based on Luma chequen essential oil. The anxiety index was evaluated by State-Trait Anxiety Inventory (STAI). Measures were taken at two times: pretest and posttest.&lt;strong&gt; Results:&lt;/strong&gt; The chemical analysis showed that α-pinene was the main component (56.5%). State and Trait anxiety scores showed a decrease in posttest study phase in comparison with pretest in experimental group compared to placebo (p&amp;lt;0.005 for state anxiety and p&amp;lt;0.05 for trait anxiety). Cohen`s d score was 0.84 in State anxiety, while it was 0.52 for Trait anxiety. Percentages of change showed reductions of anxiety variable ranging between 14.94% for State anxiety and 13.60% for Trait anxiety. &lt;strong&gt;Conclusions: &lt;/strong&gt;These results suggest that aromatherapy based on essential oil of Luma chequen was moderately effective in improving anxiety.&lt;/p&gt;
