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;

In order to evaluate the effects of &lt;em&gt;Melissa officinalis&lt;/em&gt; essential oil on state and trait anxiety, this study was conducted. &lt;strong&gt;Methods: &lt;/strong&gt;The essential oil was extracted by steam distillation and the chemical composition was investigated by Gas chromatographymass spectrometry (GC–MS). In addition, a Quasi experimental study with measures at pretest-posttest was conducted, where 58 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;Melissa officinalis&lt;/em&gt; 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 β-cubebene (26.3%), β-caryophyllene (25.4%) and geranial (12.5%) were de main components. Both state and trait anxiety levels decreased in the experimental group during the posttest phase; however, only state anxiety demonstrated statistically significant differences (p&amp;lt;0.05). A moderate size effect was found for state anxiety (d = 0.799; g= 0.797) with 1-β=0.803; but none for trait anxiety. &lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;Melissa officinalis&lt;/em&gt; essential oil was moderately effective on state anxiety but has no effect on trait anxiety.&lt;/p&gt;
