Lavender is primarily known for its essential oil, which is obtained from the flowers of the plant. The essential oil of lavender contains various active compounds, including several different classes of chemicals such as esters, alcohols, ketones, and terpenes. The main active components responsible for the characteristic aroma and potential therapeutic effects of lavender oil are linalool and linalyl acetate. Linalool is a monoterpene alcohol that contributes to the floral scent of lavender. It possesses calming and relaxing properties and is believed to have potential anti-anxiety and sedative effects. Linalyl acetate is an ester found in lavender oil and is responsible for its sweet, fruity aroma. It is also thought to have calming effects on the nervous system.
