-"Perennial, shortly rhizomatous. Culms tufted, robust, up to 2 m tall, ca. 4 mm in diam., farinose below nodes. Leaf sheaths glabrous, greenish inside; leaf blades glaucous, 30-90 × 0.5-2 cm, both surfaces scabrid, base gradually narrowed, apex long acuminate;  ... This species (Lemon Grass), known only from cultivation, is grown on a large scale in parts of tropical Asia and South America for the lemon-scented oil extracted from its leaves. The oil is used for both medicinal and culinary purposes. Flowers are seldom produced." \\ +"Perennial, shortly rhizomatous.

 Cymbopogon citratus and [[cymbopogon_flexuosus_nees_ex_steud._j.f._watson|Cympogon flexuosus]] are the source of lemongrass oil, which is valued for its citral content, with fresh, strongly citrusy, lemon-like and pungent odor. Lemongrass oil from various origins contained mainly geranial (10-62%) and neral (3-38%), together with geraniol (0.1-40%), and myrcene (0.1-21%). \\ Cymbopogon citratus and [[cymbopogon_flexuosus_nees_ex_steud._j.f._watson|Cympogon flexuosus]] are the source of lemongrass oil, which is valued for its citral content, with fresh, strongly citrusy, lemon-like and pungent odor.

The major components of the essential oil, as determined by hydrodistillation followed by gas chromatography and mass-spectrometry were citral (41% geranial and 30% neral), myrcene (15%), geraniol (5%), and lower levels of nerol and other volatiles (0.5%)." \\ "The leaves contain up to 1.5% (d.wt) essential oils with a typical lemon-like aroma, ...

 Citral and the leaf extract of C. citratus significantly reduced the spontaneous, ACh- and KCl-induced contractions of isolated rabbit ileum. Citral almost abolished the effect of increasing strength of contraction of added CaCl2, while the leaf extract shifted the calcium concentration-response curve to the right, suggesting a calcium antagonistic effect. \\ Citral and the leaf extract of C. citratus significantly reduced the spontaneous, ACh- and KCl-induced contractions of isolated rabbit ileum.
