Neroli is steam-distilled from the blossoms of bitter orange (Citrus aurantium var. amara) and is among the most prized aromatics in perfumery, distinguished by a rich floral-citrus character built on linalool (25-35%), linalyl acetate, and the uniquely floral indole. Its anxiolytic effects are among the most clinically documented of any essential oil: a double-blind placebo-controlled trial in 140 patients with acute coronary syndrome found that inhaled neroli significantly reduced anxiety scores compared to placebo.^[1] A randomised controlled trial in labouring women confirmed that neroli inhalation produced significantly lower perceived anxiety at all measured stages of labour.^[2]
