OBJECTIVES The objective of this study was to evaluate the potential anxiolytic effect of sweet orange (Citrus sinensis) aroma in healthy volunteers submitted to an anxiogenic situation. DESIGN Forty (40) male volunteers were allocated to five different groups for the inhalation of sweet orange essential oil (test aroma: 2.5, 5, or 10 drops), tea tree essential oil (control aroma: 2.5 drops), or water (nonaromatic control: 2.5 drops). Immediately after inhalation, each volunteer was submitted…

This review will explore the anxiolytic and sedative properties of aromas found in common beverages, such as coffee, tea, and whisky as well aroma found in food, spices, volatile organic compounds, and popular botanicals and their constituents to provide greater insight into viable anxiety treatment options.

A Systematic Review of the Anxiolytic-Like Effects of Essential Oils in Animal Models

A systematic review of essential oils, their bioactive constituents, and anxiolytic-like activity is conducted, finding that Lavendula angustifolia is the essential oil with the best profile, which has already been tested in controlled clinical trials with positive results.

Effects of essential oil inhalation on objective and subjective sleep quality in healthy university students

Although no obvious effect was observed in good sleepers, the inhalation of lavender oil could be effective for helping poor sleepers improve objective sleep quality, and sweet orange seemed more effective than lavender in the subjective sleep measures.

Anxiolytic-like effect of sweet orange aroma in Wistar rats

A simple simulated public speaking test for evaluating anxiolytic drugs.

SPS using an audiocassette recorder is sensitive to a prototypical anxiolytic and may thus be a useful test for evaluating putative anxIOlytic drugs, and the present negative result may be explained by clinical data indicating that patients may experience a longer lag period before the onset of the anxioytic effect of buspirone.

Why aromatherapy works.

The systematic review of aromatherapy identified only small, poor quality studies and concluded that existing work is sufficiently flawed to prevent firm conclusions from being drawn, but despite these reservations, five of the six studies included in this review reported positive effects of arom Heatherapy, albeit short-term, in reducing anxiety and increasing well-being.
