    Type: Herb. Linn. 691.2 (LINN).

    Distribution: Pakistan, Afghanistan, India (Punjab, Utter Pradesh, Bihar, Bengal, Peninsular India), Sri Lanka (Ceylon), Sikkim, Bhutan, Australia, tropical and north Africa.

    Common throughout Pakistan in plains and low hills in moist shady places and sandy to silty clay loam soils of barren lands and cultivated fields as a weed.

    The mucilage, obtained from the plant by macerating it in water, is used as a demulcent. The bitter seeds called Isband (Sind) and Raja Jira (Bombay) have been used by natives in fever and abdominal obstructions. The coarse fibre is employed in manufacturing cordage.
