Botanical name

(True) Lavender - Lavandula angustifolia Mill.


Labiatae (Lamiaceae)

Useful information about the plant

The heat-loving lavender is native to the Mediterranean where it is cultivated in large scale. The name "Lavandula - Lavender" is derived from its earlier widespread use as a fragrant addition to bath water (lavare lat = to wash). The epithet angustifolia (lat = narrow-leaved) refers to its narrow leaves.
The pleasant aromatic and fragrant lavender is a 30 to 60cm high shrub with narrow, blue-green leaves about 5cm long. The lower leaves have small white hairs, its edge is more or less rolled. The flowers are in dense whorls at the end of a long stem and form a pseudo-spike. The blue-violet corolla consists of a bilobed upper lip and a slightly smaller three-lobed lower lip. That is how they look out of the tube-shaped, oval, blue-gray cup. When dried, the corolla falls off easily or shrinks a lot so that only the cups can be seen. The lavender fields are in bloom in late July to August.

Medicinally used plant parts (drug)

The flowers with their pleasant sweet fragrance that are stripped from the stems are used. It is created by an essential oil, which is in the glandular scales on the surface of the flowers. If these glands are opened rubbed, they release the essential oil.
The commercially available drug comes from France, Spain and Eastern Europe.
