About

Strychnos madagascariensis, the black monkey orange, is an African tropical and sub-tropical tree belonging to the Loganiaceae family. It is a tree with characteristically large fruit but can confused with some other species of the genus.

Where it grows

It is native to KwaZulu-Natal, Mozambique, Transvaal, and further north to Zimbabwe, Botswana, Malawi, Zambia, Tanzania, Tropical Africa and the western side of Madagascar.

Uses

The tree is a close relative of Strychnos nux-vomica, the seed of which is a source of strychnine. Fishing with poisonous plants used to be a common practice in Africa, and though outlawed is still employed in remote areas. As with other species of Strychnos the seeds are pulverised and thrown into a pool or dammed sections of a stream, affected fish soon rising to the surface, while subsequent cooking breaks down the poison. Oils extracted from the inner skin of the fruit have a high oleic acid content.
