Description of the Plant

A tall, much-branched annual, highly aromatic herb. Leaves 3.8-8, oblong-lanceolate, obtuse or acute, sinuate-dentate, the upper leaves almost entire. Flowers minute, clustered, forming slender, axillary and terminal simple or paniculate leafy spikes.

Using Information

An infusion of the herb is considered stomachic, carminative, diaphoretic, anthelmintic and emmenagogue. The plant is used in Europe in pectoral complaints, and in nervous affections, particularly cholera. Juice of the plant is used in gangrenous ulcers, pyemia, gastralgia and nervous affections. Infusion made from leaves and seed are used chiefly for ascaris, ascarides and ankylostoma. Volatile oil having ascaridol is effective against hookworms, roundworms, intestinal amoeba and skin fungi.

Essential oil from leaves possesses antimicrobial activity and strong antifungal against human pathogenic fungi (Asolkar et al., 1992).

Chemical Constituents

The chief constituent of the plant is an essential oil present in its fruits. Oil contains high content of ascaridol, along with xylene isomers, p-cymene, an alcohol and four carboxylic acids, (-)pinocarveol and (+)a-pinene. Active principles of the oil are ascaridol (C10 H16O2), up to 90%, its isomers and their derivatives. Ascaridol is a powerful worm expellent. It also contains various hydorcarbons and lower fatty acids.


Leaves contain the flavonol glycoside, kaempferol-7-rhamnoside and ambroside and oxalic and malic acids. Triterpenoids saponins, vitamin C and magnesium phosphate have also been reported form the roots. Kaempferol, iso-rhamnetin and quercetin and the flavonol glycoside, kaempfeol-3-rhamnosied-4-xyloside and kaempferol-3-rhamnoside-7-xyloside have been identified in the fruits (Ghani, 2003; Rastogi & Mehrotra, 1993).
