T1 - Trade of wild-harvested medicinal plant species in local markets of Tanzania and its implications for conservation JF - South African journal of botany : an international interdisciplinary journal for botanical sciences N2 - In Tanzania, about 10% of the reported 12,000 species of higher plants are estimated to be used as medicine for treating different human health problems. Most of the medicinal plants are collected from wild populations, but their trade and quantities are not properly recorded. Monitoring of trade in wild-harvested medicinal plants is challenging asmostmaterials are traded in various processed forms and most vendors practice informal trade. Yet, monitoring is important for conservation and sustainability. This study aims to assess the trade of wild-harvested medicinal plant species in local markets of Tanzania and its implications for conservation. Semi-structured interviews were used to record frequency, volume of trade and uses of wild-harvested medicinal plants in Arusha, Dodoma, Mbeya, Morogoro and Mwanza regions. Relative frequency of citation and informant consensus factor were calculated for each species and mentioned use category. Forty vendors were interviewed, and 400 out of 522 collected market samples were identified to 162 species from herbarium-deposited collections. Plant parts with the largest volume of trade were roots (3818 kg), bark (1163 kg) and leaves (492 kg). The most frequently traded species were Zanthoxylum chalybaeum Engl., Albizia anthelmintica Brongn., Zanha africana (Radlk.) Exell, Warburgia stuhlmannii and Vachellia nilotica (L.) P.J.H. Hurter & Mabb. The most popular medicinal plants in the markets are connected to local health problems including malaria, libido disorders or infertility. The high diversity of commercialized plants used for medicinal issues mainly relies on wild stock for local consumption and international trade, and this has significant implications for conservation concerns.

T1 - Diversity of Hypoxis species used in ethnomedicine in Tanzania JF - South African journal of botany : an international interdisciplinary journal for botanical sciences N2 - The corms of different Hypoxis species (Hypoxidaceae) are used for the treatment and management of a variety of human ailments and disorders in African traditional medicine. However, the used corms are morphologically similar and it is not known whether this has resulted in different species being harvested, prescribed and sold as the same species. Ethnomedicinal information regarding its use in Tanzania is scanty and the available ethnobotanical information about the plants is mostly from various studies done outside Tanzania. The objective of the study was to document the diverse uses of Hypoxis in Tanzania and study what species are used and whether preferences exist for specific species. Focus group discussions and in depth interviews with informants were done in 15 regions of Tanzania to document local uses of Hypoxis species and collect vouchers for identification. Traditional practitioners use Hypoxis to manage a variety of human illness in Tanzania, and appear to use different species indiscriminately for medicine, socio-cultural applications and for food. Medicinal uses include treatment of benign prostate hypertrophy, cancer, diabetes, gout, headache, HIV/AIDS, infertility, ringworms, stomachache, and urinary tract infections. In Tanzania, different Hypoxis species are used indiscriminately for a range of sociocultural and medicinal purposes. The reported medicinal uses could aid testing and evaluation of traditional herbal medicine and more research is needed to test their pharmacological effects. (C) 2018 SAAB.
