Pergularia daemia, the trellis-vine, is a hispid, perennial vine in the family Apocynaceae, with an extensive range in the Old World tropics and subtropics.[citation needed] It has been used traditionally to treat a number of ailments.[citation needed]

Range and habitat[]

It occurs from the Malay Peninsula to Burma, India, Sri Lanka, Pakistan, Afghanistan through Arabia and Egypt to central and southern Africa.[1] It is found along roadsides, in woodland or along riparian forest fringes.[2]

Description[]

The opposite[citation needed] and broadly ovate to suborbicular leaves are very variable in size, with petioles of varying length. The leaves are almost glabrous above and velvety below.[1]

In the northern hemisphere the flowers appear from mid to late winter, and these are carried on lateral cymes. The flower corolla forms a greenish-yellow or dull white tube.[1] The fruit mature after some 13 to 14 months[citation needed] when they release ovate seeds covered with velvety hairs.[1]

Phytochemical properties[]

Terpenoids, flavonoids, sterols and cardenolides are among the chemicals that have been isolated from either the leaves, stems, shoots, roots, seeds or fruit.[citation needed] Traditionally it has been used as an anthelmintic, laxative, antipyretic and expectorant, besides treatment of infantile diarrhoea, malarial intermittent fevers, toothaches and colds.[citation needed] Studies have shown hepatoprotective, antifertility, anti-diabetic, analgesic, antipyretic and anti-inflammatory properties of substances in its aerial parts.[citation needed]

Associated species[]

The larvae of the African monarch butterfly (Danaus chrysippus aegyptius) feed on this species.
