Effect of Rosmarinus Officinalis Essential Oil On Anxiety, Depression, And Sleep Quality

Introduction: The objective of this investigation was to evaluate the effect of Rosmarinus officinalis essential oil on anxiety, depression, and sleep quality. Methods: The essential oils were extracted by hydro-distillation using a modified Clevenger-type apparatus and the chemical composition was performed by Gas chromatography with flame ionization detection (GC-FID) and Gas chromatography mass spectrometry (GC–MS). 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). Results: 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<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. Conclusion: Essential oils extracted from Rosmarinus officinalis are more effective in calming anxiety and show moderate changes in depression and sleep quality

Índice de oxidabilidad del aceite de Helianthus annuus L. “Girasol” expuesto a calentamiento discontinuo en frituras de carne fresca y desecada

La presente investigación tuvo como objetivo determinar el Índice de oxidabilidad del aceite de Helianthus annuus L. “Girasol” expuesto a calentamiento discontinuo en frituras de carne de bovino fresca y desecada en un recipiente de acero inoxidable. Se utilizó 10,0 litros de aceite de girasol y 25 kg de carne en porciones de 500 g, 12,5 kg de carne fresca y 12,5 kg desecada. El proceso de fritura de cada muestra se realizó cada 8 horas hasta obtener un total de 25 muestras. Antes de la primera fritura (muestra basal) y después de cada fritura se tomaron 50 mL de aceite para análisis del Índice de oxidabilidad y porcentaje de acidez. El aceite calentado en forma discontinua para freír carne fresca y desecada incremento el Índice de oxidabilidad respecto a la muestra basal. El mayor porcentaje de humedad de la carne fresca incremento en mayor grado el Índice de oxidabilidad, en ambos casos se afectó la vida útil del aceite, llegando a no ser apto para el consumo a partir del segundo día por la mañana.

Anxiolytic-like Effect of Luma chequen Essential Oil: A Pilot Study

Introduction: Essential oils are complex substances used widely extended in the form of aromatherapy or phytotherapy, some of them as agents to relieve anxiety and stress. In this sense this study was conducted to examine the anxiolytic-like effect of Luma chequen essential oil. Methods: 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. Results: 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<0.005 for state anxiety and p<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. Conclusions: These results suggest that aromatherapy based on essential oil of Luma chequen was moderately effective in improving anxiety
