About Warburgia salutaris (Bertol.fil.) Chiov.
Warburgia salutaris, commonly called the pepper-bark tree, is a tree species belonging to the Canellaceae family. It has multiple common names across regional southern African languages: Peperbasboom in Afrikaans, Molaka in Sotho, Mulanga in Venda, and Isibaha in Zulu. This species occurs in eastern and southern Africa, with confirmed populations in Botswana, Namibia, Kenya, Tanzania, Zambia, Mozambique, South Africa, Eswatini, Malawi, and Zimbabwe. It is currently threatened by habitat loss. The tree is a popular medicinal plant, and overharvesting from wild populations is an additional factor contributing to its endangered status. It is designated as a protected tree in South Africa, and various research projects are exploring controlled propagation methods to support future outplanting into wild habitats. This is an erect evergreen tree that typically reaches a maximum height of around ten meters, though individuals may occasionally grow to 20 meters tall. It produces a thick canopy of aromatic, shiny green leaves. The leaf blades are lance-shaped, growing up to 11 centimeters long and 3 centimeters wide. Its flowers have ten yellow-green petals, each measuring just under one centimeter long. Flowers grow either singly or in small clusters of up to three blooms. The fruit is a leathery berry that turns purple or black when ripe, and can reach up to 4 centimeters wide. The leaves of this tree are used to add a peppery flavor to food and tea. The bitter taste of the tree's bark and leaves comes from naturally occurring iridoids. Its aromatic, oily, yellowish wood is used for firewood. The species is also attractive and makes a good shade tree. In traditional medicine practices, the Maasai people use this plant to treat malaria. It is prepared as snuff or smoked to address respiratory complaints including the common cold and cough. Dried bark of the tree is sold in markets in Tanzania and other regions. Dried bark is also chewed, and the juice is swallowed, as a traditional remedy for stomach-ache, constipation, coughs, fever, toothache, muscle pains, weak joints, and general body pains.
