About
Zanha africana, commonly known as the velvet-fruited zanha in English and as mkalya or mkwanga in Swahili, is a species of plant in the family Sapindaceae that is native to Africa. It is used locally for timber and herbal medicine.
Where it grows
Zanha africana is native to Angola, Botswana, the Democratic Republic of the Congo, Kenya, Malawi, Mozambique, Namibia, Tanzania, Zambia, and Zimbabwe. It grows in open woodlands, including those on granite ridges or kopjes, and in riparian forests at altitudes of 600–1,550 m (1,970–5,090 ft).
Uses
The wood of Zanha africana is hard, durable, and somewhat resistant to attacks by wood-eating insects. Though it is not considered commercially valuable as timber, it is used locally for construction, agricultural implements, firewood, furniture, mine props, shipbuilding, turnery, and railway sleepers. The fruits are eaten by humans, reportedly tasting similar to apricots, but the seeds are believed to be poisonous and eating large quantities of the fruit may cause diarrhoea. Several parts of the plant contain saponins and may be used as substitutes for soap. The bark, leaves, and roots of Z. africana are widely used as herbal medicine for a variety of ailments, including aches and pains, convulsions, fevers, fungal infections, headaches, hypertension, intestinal parasites, nausea, respiratory problems, and sexually transmitted infections.
