NOW Foods Lavender Oil is a 100% pure essential oil steam-distilled from the flowering tops of Lavandula angustifolia — the true lavender species prized for its superior aromatic complexity and therapeutic profile over hybrid lavandin varieties. Lavender is the most researched and widely used essential oil in aromatherapy, with clinical studies demonstrating its ability to reduce anxiety, improve sleep quality, lower heart rate and blood pressure during stress, and provide mild analgesic and anti-inflammatory effects when applied topically. The primary active constituents — linalool and linalyl acetate — are responsible for both its calming aroma and its biological activity. NOW Foods verifies composition via GC/MS testing to ensure authentic Lavandula angustifolia — not the cheaper lavandin hybrid. Dilute in carrier oil for skin use. Diffuse for aromatherapy.
