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 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 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. Traditionally it has been used as an elmintic, laxative, antipyretic and expectorant, besides treatment of infantile diarrhoea, malarial intermittent fevers, toothaches and colds. Studies have shown hepatoprotective, antifertility, anti-diabetic, analgesic, antipyretic and anti-inflammatory properties of substances in its aerial parts.

Associated species

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

gollark: if it does, of course.
gollark: You probably want to revert that when the program *exits*.
gollark: > Which is exactly what they wanted here!Not necessarily, this actually does sound like a case where they might want each task to run in its own coroutines (or would, if their pathfinding did yields).
gollark: I mean, it's great for very simple situations where you want to run two things at once in the simplest case, but often projects want to run a listener "thread" and temporarily spawn tasks to handle them or something and this ends up being constantly reinvented.
