Uses

In Tanzania a cold water extract of the stem is drunk to treat abdominal pain. An extract is used as a bath to treat itches. In Kenya the Maasai people use the tuberous stem as cattle medicine. Adenia globosa is grown for ornamental purposes in South Africa and in greenhouses in the temperate regions.

Production and international trade

Adenia globosa is collected, grown and traded as an ornamental by plant amateurs.

Properties

The aerial parts of Adenia globosa contain the cyanogenic glycosides deidaclin and its stereoisomer tetraphyllin A.

Botany

Dioecious shrub or climber up to 8 m tall, with a swollen, warty globular trunk up to 2.5 m in diameter; stems erect or scandent, more or less succulent, with axillary, up to 8 cm long thorns. Leaves alternate, simple and entire to 3-lobed, soon falling; petiole 1–1.5 mm long; stipules narrowly triangular, c. 0.5 mm long, acute; blade triangular, 3–7 mm × 1.5–9 mm, base rounded, apex acute, with 1 kidney-shaped gland at base. Inflorescence an axillary cyme, 1–5-flowered; peduncle up to 1.5 mm long; bracts and bracteoles triangular. Flowers unisexual, regular, 5-merous, greenish white; pedicel up to 1(–1.5) cm long, jointed near base; calyx tube about as long as lobes; petals free, exserted, toothed; male flowers up to 2 cm long, filaments of stamens fused at base, anthers free, ovary rudimentary; female flowers up to 1 cm long, ovary superior, ovoid to ellipsoid, 3-ribbed, styles 3, fused at base, stigmas kidney-shaped, stamens rudimentary. Fruit a stalked globular to ovate-ellipsoid capsule 1–3 cm × 1–2 cm, leathery, smooth, green, many-seeded. Seeds broadly ovoid, flattened, 6–7 mm × 3–5.5 mm × 3 mm, pitted.
Adenia comprises about 95 species, with about 60 species on the African continent, 20 in Madagascar and 15 in Asia. The genus is subdivided in 6 sections. Adenia globosa, and several other species with medicinal uses belong to section Adenia. Adenia venenata Forssk. occurs from Nigeria east to Eritrea and south to Tanzania. In DR Congo Adenia venenata is cultivated near villages and is used to treat intestinal worms. In Kenya Turkana people use the leaves to treat cattle suffering from mange. In Madagascar the pounded stems of Adenia subsessilifolia Perr. are applied to wounds. The tubers are bitter and inedible.

Growth and development

Ecology

Adenia globosa occurs in scrub savanna at 100–1800 m altitude.

Propagation and planting

Genetic resources and breeding

Adenia globosa is widely distributed and hence not threatened with genetic erosion.

Prospects

Adenia globosa is only locally used, and will remain of little importance unless pharmacological research shows new possibilities. The prospects of Adenia globosa as an ornamental seem promising because of the growing interest in unusual plants by specialized amateurs.
