Lavender Herb – Uses And Side Effects

Lavender Oil Uses & Benefits

Although used in small concentrations to flavor food, lavender is cultivated mainly as an ingredient in perfumes or potpourris and for decorations. Some people believe its scent has a calming effect. France is a major producer of lavender products.

Lavender comes from the flowering tops and stalks of Lavandula officinalis and other Lavandula species. Native to the Mediterranean area, lavender is cultivated widely in American gardens for its color and fragrance. Lavandin, a popular variety, is a hybrid of spike lavender and true lavender.

Lavender is a bushy, branching shrub, whose lower branches are woody, although the young stems are herbaceous. It grows to a maximum height of three feet. Stems and leaves are covered with fine grey hairs. The evergreen leaves are silvery grey, eight times as long as wide, up to two inches in length, linear, smooth edged, and opposite. The flowers are produced on terminating, wiry blunt spikes 6-8 inches long, and grow in whorls of 6-8 flowers, subtended by short pointed bracts. The calyx is purple-grey, tubular, with thirteen veins and five lobes, one of which is slightly larger than the others. The small purple-blue flowers have four stamens and a tubular corolla with two lips: the upper lip has two lobes and the lower lip three. Examination of the corolla with a hand lens shows a dense covering of stellate hairs and small shiny oil glands. It is most often identified by its fragrant, characteristic odour. Flowers June to September.
