Warburgia Salutaris | Plantz Africa About:Reader?Url= Warburgia salutaris | Plantz Africa about:reader?url=http://pza.sanbi.org/warburgia-salutaris pza.sanbi.org Warburgia salutaris | Plantz Africa Introduction This tree is a priority species for conservation and cultivation in gardens, as it is over-harvested in the wild for medicinal use and is a very popular item for sale at street markets. Description Description This is an evergreen, slender tree that grows from 5 to 10 m tall. The dark green, glossy leaves are paler green below with entire margins. They are simple, alternately arranged, elliptic to lanceolate. The midrib is slightly off-centre with a tapering apex and base. The leaves have a bitter, burning, aromatic taste. It has white to greenish flowers of up to 7 mm in diameter. The flowers are solitary, axillary, or in tight, few-flowered heads, borne on short, robust stalks in the axils of the leaves. These flowers develop into round, oval berries, narrowing towards the base. They are dark green, turning purple when ripe, leathery in texture and covered with glands. The stem is covered by a rich brown bark that is also bitter and peppery. Conservation Status 1 of 3 2016/12/15 01:48 PM Warburgia salutaris | Plantz Africa about:reader?url=http://pza.sanbi.org/warburgia-salutaris Status Due to its wide range of medicinal uses, this tree is over-harvested and should be a candidate for conservation. Distribution and habitat Distribution description This is a tropical forest tree which extends southwards as far as KwaZulu-Natal, eastern and northern Gauteng and across Swaziland. It also occurs in Malawi. Its growth habitat is forests and kloofs. Derivation of name and historical aspects History The genus Warburgia was named after Dr Otto Warburg, 1859-1938, who was born in Hamburg. He lectured in botany at the University of Berlin, Germany, and was also the author of numerous botanical papers. The specific epithet salutaris is Latin meaning healthful. The English common name, pepper-bark, relates to the pungent inner bark. Isibaha is an old name in the history of Africa, and is thought to be based on an Arabian word which dates back to the days when the Arabs traded with Africa. Uses Use Medicinally, the pepper-like, bitter stems and root bark are used to cure many ailments. As an expectorant or smoked, they are a widely used remedy for common colds. Dried and ground, they make a snuff used to clear the sinuses. Taken orally they are believed to cure spots in the lungs. Both stems and root bark are a remedy for malaria. Powdered and mixed with water, they are believed to cure sores in the mouth. The wood is not well known for timber in South Africa probably because of its rarity. According to Palmer & Pitman (1973), in Kenya the leaves of the pepper-bark are sometimes added to curries, and the wood is sometimes used in building. Growing Warburgia salutaris Grow Warburgia salutaris can be cultivated from seed as well as vegetatively from cuttings. Cuttings should be taken in spring. The tree grows in well-drained soil, with good aeration. Soil should be rich in organic matter in the form of well-rotted compost. The pepper-bark is an attractive evergreen tree for both small gardens and big estates. It is also a suitable plant for hedge as it responds well to pruning. 2 of 3 2016/12/15 01:48 PM Warburgia salutaris | Plantz Africa about:reader?url=http://pza.sanbi.org/warburgia-salutaris The pepper-bark is sensitive to frost and should be protected when young.

  • The Endangered Wildlife Trust Embarks on New Project to Save Nature’S Life-Givers
    29 November 2019 The Endangered Wildlife Trust embarks on new project to save nature’s life-givers Start In another first for the Endangered Wildlife Trust (EWT), we are proud to announce that we are embarking on a new project to save nature’s life-givers – trees. The Pepper Bark Tree (Warburgia salutaris) is listed as Endangered, both globally and nationally, on the IUCN Red List. This is largely due to illegal and unsustainable harvesting of these trees for their bark, which is commonly used in traditional medicine, including many remedies that are used to treat influenza, diarrhoea, burns, and other ailments. The EWT is excited to be embarking on an ambitious project that could change the fate of these trees. The project will initially focus on the western Soutpansberg, a region where the EWT is already engaged in critical conservation work through our Soutpansberg Protected Area, and a known priority area for the species. The plan to save the Pepper Barks is threefold. The team will conduct strategic research to understand the geographic priorities, conservation needs and mitigation options for the conservation of the species; implement targeted habitat protection and restoration work in the Soutpansberg, including clearing of invasive species and the proclamation of 22,803 hectares of privately-owned land into Privately Protected Areas; and work with Traditional Health Practitioners (THPs) to conserve wild Pepper Barks. Traditional medicine remains a critical health care modality throughout southern Africa due to its cultural significance as well as limited access to western medical care in many parts of the sub-region.

Stem-bark and leaves are used as remedies for malaria, stomachache, coughs and several skin diseases. Consequently, the plant is endangered because of uncontrolled harvest from the wild and lack of domestication. There is therefore fear of poor quality commercialized products due to lack of quality control mechanisms. The objective of this study was to investigate features of diagnostic value that could be used to confirm its authenticity and purity. Samples in the study were obtained from six different geographical locations in Kenya by random purposive sampling. Macroscopic and microscopic studies of the leaf and stem-bark were done based on a modified method from the American herbal pharmacopoeia. The study revealed over five macroscopic and organoleptic characteristics for W.

Warburgia salutaris, the pepper-bark tree, is one of the most highly valued medicinal plant species in southern Africa. Due to its popularity in folk medicine, it is overexploited in many regions and is deemed threatened throughout its range. We identified cultural and social drivers of use, compared knowledge distribution, determined management practices, and explored local ecological knowledge related to the species in the Lebombo Mountains, Tembe River, and Futi Corridor areas in southern Mozambique. Stratified random, semistructured interviews were con- ducted (182), complemented by 17 focus group discussions in the three study areas. W. salutaris was used medicinally to treat 12 health concerns, with the bark being the most commonly used part. Knowledge of the species varied between the three areas, but not with respondent gender or age. Harvesting was mostly through vertical bark stripping (71% of informants).

This review focused on the phytochemical contents, medicinal uses and antimicrobial activities of W. ugandensis based on published peer reviewed articles. This review established that the high therapeutic value of W. ugandensis is attributed to the abundance of drimane sesquiterpenes in its stem bark and leaves.
