Botanical name

Rosemary - Rosmarinus officinalis L.


Labiatae (Lamiaceae)

Useful information about the plant

Rosemary is native throughout the Mediterranean up to Portugal. The name comes from the Latin "ros marinus", which means "dew of the sea," although it is not clear how it arrives at this description. The epithet officinalis suggests that it is an ancient medicinal plant, the "officina" is the sales room of a pharmacy. The fragrant shrub of rosemary grows up to 1 metre high. The hard, narrow-lineal leaves that look like needles with white-tomentose hairs underneath are very characteristic. When rubbed they smell pleasantly of the essential oil. It is in the glandular scales on the leaf surface and as they are broken the essential oil is released. There are pale blue to mauve lip flowers in the leaf axils. Flowering time is May to June.

Medicinally used plant parts (drug)

The dried leaves are used with their typical scent of rosemary, which is clearly perceived when rubbed. The commercially available drug comes from imports from Spain, Morocco, Tunisia and South Eastern Europe.

Ingredients of the drug

Rosemary leaves contain essential oil ("rosemary oil"), with its aromatic scent made of 1.8-cineole, camphor, pinene and other monoterpenes plus bitter terpenphenolics and Lamiaceae tannins (mainly rosmarinic acid).
