Warburgia salutaris (Bertol.f.) Chiov. | |
Warburgia salutaris (pepper-bark tree, Afrikaans: Peperbasboom, Sotho: Molaka, Venda: Mulanga, Zulu: Isibaha)[1] is a species of tree in the Canellaceae family. It is found in Botswana, Namibia, Tanzania, Zambia, Mozambique, South Africa, Swaziland, Malawi and Zimbabwe. It is threatened by habitat loss. It is a popular medicinal plant and is overharvested in the wild, another reason for its endangerment.[2] The Pepper-bark tree is a protected tree in South Africa.[1] Various projects are investigating methods of propagation under controlled conditions with subsequent planting in the wild.[3]
This is an erect tree growing up to about ten metres in maximum height, but known to reach 20 metres at times. It has a thick canopy of aromatic, shiny green leaves. The evergreen leaf blades are lance-shaped, measuring up to 11 cm long by 3 wide. The flowers have ten yellow-green petals. They are each just under a centimeter long and are solitary or borne in small clusters of up to 3. The fruit is a berry, leathery purple or black in color when ripe, measuring up to 4 cm wide.
The leaves are used to add peppery flavoring to food and tea.[3] The bitter taste of the tree's bark and leaves is due to the presence of iridoids.[4] The herbage and fruit are fed to animals.[3] The aromatic, oily, yellowish wood is used for firewood.[3]
This plant is used medicinally by the Maasai people to treat malaria.[5] It is used as a snuff or smoked for respiratory complaints such as common cold and cough.[3] The bark can be purchased at markets in Tanzania,[6] and elsewhere.[7] A chemical compound isolated from the bark of the tree shows antimicrobial activity at high concentrations.[4]
It is attractive and makes a good shade tree.[3]
