Lavender oil is an essential oil obtained by distillation from the flower spikes of certain species of lavender. Two forms are distinguished, lavender flower oil, a colorless oil, insoluble in water, having a density of 0.885 g/mL; and lavender spike oil, a distillate from the herb Lavandula latifolia, having density 0.905 g/mL. Like all essential oils, it is not a pure compound; it is a complex mixture of naturally occurring phytochemicals, including linalool and linalyl acetate. Kashmir Lavender oil is famous for being produced from lavender at the foothills of the Himalayas. As of 2011, the biggest lavender oil producer in the world is Bulgaria.
Uses
Lavender oil has long been used in the production of perfume.
It is used in aromatherapy but there is little evidence that it does anything.
Oil of spike lavender was used as a solvent in oil painting, mainly before the use of distilled turpentine became common.
Research
Small clinical studies of Silexan, an oral preparation of lavender oil, have been found it may be useful for alleviating low-level anxiety and sleep disorders.
Lavender oil has been implicated in prepubertal gynecomastia, the abnormal development of breasts in pre-adolescent boys.
Composition
The primary components of lavender oil are linalool (51%) and linalyl acetate (35%). Other components include α-pinene, limonene, 1,8-cineole, cis- and trans-ocimene, 3-octanone, camphor, caryophyllene, terpinen-4-ol and lavendulyl acetate.
