Introduction: This study aimed to evaluate the anxiolytic effect of Mentha piperita essential oil on state and trait anxiety. Methods: The essential oil was extracted by hydrodistillation, and its chemical composition was analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). 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{\textquoteright}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). Conclusion: These findings suggest that Mentha piperita essential oil may effectively reduce state and trait anxiety, with a more pronounced impact on state anxiety.

Introduction: The aim of this research was to evaluate the effects of Satureja brevicalyx essential oil inhalation on premenstrual syndrome. Methods: The oils were extracted by hydro-distillation using a modified Clevenger-type apparatus and chemical composition was performed by Gas chromatography-mass spectrometry (GC{\textendash}MS). Furthermore, a quasi-experimental study was conducted, where 61 participants were divided in two groups, comprising an experimental with essential oils and a control group with no treatment. Main psychological symptoms were assessed with the used of Zung Self-Rating Anxiety Scale (SAS) and Zung Self-Rating Depression Scale (SDS) as well as total score of premenstrual syndrome was evaluated with Premenstrual Syndrome Scale (PMSS). Results: chemical analysis showed that linalool (17.6\%) was the main component. All variables showed a decrease in posttest study phase in comparison with pretest in experimental group (p\<0.05). A large size effect was observed for anxiety (d = 1.25; Δ = 1.35). Besides, moderate changes were found for depression (d = 0.79; Δ= 0.81) and premenstrual syndrome total score (d = 0.62; Δ = 0.56). Conclusion: The essential oil of Satureja brevicalyx exerts a potencial use, especially for the treatment of psychological symptoms of premenstrual syndrome.
