An aromatherapy remedy with a sweet and spicy aroma, neroli essential oil is sometimes used to ease anxiety. Proponents claim that breathing in the scent of this essential oil (sourced from the flowers of the bitter orange tree) can help promote calm and stop excessive worrying.
Although research on the health effects of neroli essential oil is fairly limited, there's some evidence that neroli may aid in the treatment of anxiety. In a 2013 study published in Evidence-Based Complementary and Alternative Medicine, for example, an aromatherapy blend containing neroli essential oil was found to reduce anxiety and alleviate sleep problems in a group of coronary angioplasty patients.
