A study published in 2014 found that women who self treated with neroli oil aromatherapy experienced significant improvement in menopause symptoms, increased libido and reduced blood pressure. The women self-treated for 10 sessions twice daily for five consecutive days. Each participant poured 1 mL of 0.1% or 0.5% neroli oil or an almond oil control onto a fragrance pad while sitting, with the pad 30 cm away from the nose for five minutes.
