Lavender is a shrub of the mint family, famously grown in England and France. The essential oil is obtained by steam distillation or solvent extraction of the inflorescence. Its scent is a rough herbal note, but among the many herbal scents, it has the strongest floral elegance. This is because linalool and linalyl acetate, which are contained in floral notes, are the main components. Lavender is divided into various grades depending on the place of origin and the variety, but the higher the linalyl acetate content, the more expensive it is. Lavender has been used to scent laundry and baths since ancient Rome, and its etymology is thought to be derived from the Italian word laver, which means "to wash." When used in perfume, it gives a classical and clean impression, and is an essential ingredient in citrus colognes and fougere accords.
