From tropical and subtropical Africa, through Saudi-Arabia and the Middle East to the Indian subcontinent, Indo-China and Thailand, and introduced in drier areas of Australia, Central and South America and the Mascarene Islands. Probably also introduced or spread to South-East Asia.

In Africa and India, the latex is used as a rubefacient and to extract guinea worms. The dried root bark is used in a soup to treat colic and as a stomachic. The burnt root is made into an ointment for skin eruptions and ulcers.

A large erect shrub up to 4 m tall, stems much branched at the base; leaves oblong-obovate to broadly obovate, 9—15 cm x 5—10 cm, sessile; cymes 4—10 cm in diameter, peduncle 5—8.5 cm long, pedicel 1.5—4 cm long, calyx lobes ovate-lanceolate, 5—6 mm x 3—4 mm, corolla 2.5 cm in diameter, lobes ovate-lanceolate, 6—8 mm x 4—5 mm, cream or greenish-white at the base and purple-violet towards the tip of the lobes, corona with 5 broad scales, adnate to and equalling or longer than the staminal column, basal horn incurved, bifid, without auricles, cream coloured, glabrous; follicles often in pairs, subglobose to obliquely ovoid, inflated, 6—12.5 cm x 3—7 cm. Calotropis procera is common in semi-arid conditions on sandy soils, and a weed in cropped land.
