Odour: fragrant, aromatic; taste: aromatic, bitter, somewhat camphoraceous.

An aromatic shrub, 1–2 m high. Branches grey-brown to dark brown with long fl owering and short leafy shoots, bark longitudinally peeling. Leaves clustered on leafy shoots, widely spaced on fl owering shoots; petiole very short; blade linear-lanceolate to linear, 17 mm long, 2 mm wide on leafy shoots, 2–6 cm long, 3–6 mm wide on fl owering shoots; grey stellate tomentose, base attenuate, margin entire, revolute, apex obtuse.

Infl orescence a crowded, interrupted or nearly continuous spike, 2–8 cm long; verticillasters numerous, with 6–10 fl owers, upper ones densely crowded; peduncle about three times longer than the spike; bracts papery, rhombic-ovate, 3–8 mm long, rust coloured when dry; bracteoles absent or up to 2.5 mm long, pedicel 1.0–1.5 mm long; calyx 4–7 mm long, densely grey stellate tomentose outside, with 13 longitudinal ribs, upper lip entire, appendage obcordate, lower lip four-toothed; corolla 10–12 mm long, blue, base subglabrous, throat and limb glandular hairy, upper lips straight, lower lips spreading. Nutlets narrowly cylindrical.


Contains 1.0–3.0% essential oil, of which the major constituents are linalyl acetate (30–55%) and linalool (20–50%). Other constituents include β-ocimene, 1,8-cineole (1,8-cineol, cineol, cineole, eucalyptol), camphor and caryophyllene oxide. The structures of linalyl acetate and linalool are resented below.


Antimicrobial activity
Aqueous, chloroform, hexane and methanol extracts of Flos Lavandulae, 60.0 μg/ml, inhibited the growth of Streptococcus pneumoniae in vitro.
A methanol extract of the fl owers inhibited the growth of Helicobacter pylori (the bacterium associated with peptic ulcer disease) in vitro, minimum inhibitory concentration 100.0 μg/ml.

Antioxidant activity
A 50% ethanol extract of the fl owers had antioxidant activity in vitro, median effective dose 45.0 mg/ml.

Antiulcer activity
Intragastric administration of 400.0 mg/kg body weight (bw) of an 80% ethanol extract of the flowers to mice signifi cantly (P < 0.05) reduced ethanol-induced gastric ulcerations by 62.9%.

Uterine stimulating activity
A hot aqueous extract of the fl owers (dose not specified) stimulated uterine contractions in isolated pregnant guinea-pig uterus.

Anticonvulsant and sedative activities
Intraperitoneal administration of 2.5 g/kg bw of linalool to rodents protected against convulsions induced by pentylenetetrazole, picrotoxin and electroshock. In mice, intraperitoneal administration of 2.5 g/kg bw of linalool interfered with glutamate function and delayed N-methyld-aspartate-induced convulsions. Linalool acts as a competitive antagonist of [3H]-lutamate binding and as a non-competitive antagonist of [3H]-dizocilpine binding in mouse cortical membranes, suggesting interference of glutamatergic transmission. The effects of linalool on [3H]-glutamate uptake and release in mouse cortical synaptosomes were investigated. Linalool reduced potassium-stimulated glutamate release. These data suggest that linalool interferes with elements of the excitatory glutamatergic transmission.
