An assessment of wild medicinal plants utilized by people bordering Uvinza Miombo Forests, in Kigoma region, Tanzania was conducted in 2015. Structured interviews, descriptive statistics and informant consensus were used to collect, compile and analyze the data. Four hundred informants were selected for interview. One hundred medicinal plant species were recorded most of them (63%) are largely used to treat human diseases, and less were used to treat Livestock diseases and storage pests of maize and beans. Roots (49.6%), leaves (20.9%), and barks (17.1%) formed the major plant parts used for medicines. Harvesting roots is much more destructive than bark and leaves and thus has an implication to sustainable harvesting and consequently diversity conservation.
ABSTRACT An assessment of the diversity of wild edible and medicinal plants utilized by the people in Uvinza Miombo Forests, Tanzania was done. Atotal of 400 informants (age ≥18 years) were selected to collect information on use of wild edible and medicinal plants from four sampled villages. Of these, 54 key informants were selected purposeful based on the recommendations from village leaders and elders. The rest were selected randomly. Forty circular plots were surveyed during transect line in selected four forest reserves to evaluate plant species diversity and disturbances. Sixty three wild edible and one hundred medicinal plant species were recorded to treat human, livestock and control of storage insect pests. Fabaceae, Euphorbiaceae, Rubiaceae, Verbenaceae, Anacardiaceae and Apocynaceae were the major families recorded. Forest reserves and farm lands formed the major sources of edible and medicinal plants. Fruits 82.5% constituted the largest plant part collected for food. Roots 49.6%, leaves 20.9%, and barks 17.1% formed the major plant parts used for medicines. Anisophyllea bohemii, Crossopteryx febrifuga, and Aloe species, had highest informant consensus. Vitex domiana, Pericopsis angolensis, Vitex payos, Anisophyllea boehmii and Carissa edulis were recorded as multipurpose trees. The transect walks recorded 82 plant species. Average Shannon-Wiener diversity index (H’) was valued at 2.5580, while evenness (EH) had value of 0.06512. The local community in the study area possesses indigenous knowledge on various uses of wild plants including wild edible and medicinal plants, and the forest are facing increasing disturbances. Efforts are needed to create awareness and sensitize the communities on sound utilization and participatory management of the miombo ecosystem of particular importance the biodiversity approach.

A study to document medicinal plants parts and practices in relation to sustainable use was performed in communities around the Miombo woodland of Urumwa in Tanzania. Data collection was based on semi-structured interviews and discussion with key stakeholders. G-tests were used to ascertain differences in medicinal plants practices between women and men. Roots were the commonly used parts for medicine followed by barks. In practice, boiling and grinding were the preferred methods for preparing remedies. Remedies are admistered orally in decoctions form with lack of standardized dosages. Medicinal plants are collected from the reserve using both root digging and bark stripping methods. Local communities need sensitization through trainings on various aspects of medicinal plants practices especially issues of sustainable harvesting methods, simple processing, domestication and the importance of standardized dosages so as to improve work performance, ensure resource sustainability and ...
The study was conducted with the main objective to determine the utilization and conservation of indigenous medicinal plants in Koipirir, Ilchurai and Ikumae in Baringo County. The specific objectives were to assess the composition and abundance of the common Indigenous Medicinal Plants in the study areas, to find out the diversity and evenness of Indigenous Medicinal Plants (IMPs) in the study areas, to determine the modes of utilization and harvesting of Indigenous Medicinal Plants among the rural communities in the study area and to find out the conservation measures in place to conserve Indigenous Medicinal Plants among the rural communities in Baringo County. Balanites aegyptiaca (26.26%), Acacia nilotica (17.68%) and Balanites aegyptiaca (15.80%) were abundant in Koipirir, Ilchurai and Ikumae respectively. Ikumae had high species diversity (H"2.698) and evenness (0.849), as compared to Koipirir (H"2.447) and (E 0.769) and Ilchurai (H"2.511) and (E 0.7901). Introduction; Increasing demand for medicinal plants internationally has resulted in the overexploitation and indiscriminate over-harvesting of medicinal plants [I]. The degree of vulnerability of medicinal plants to overexploitation and disturbance largely depends on the part used be it bark, leaves, twigs, roots or stem and the life form [2] species and partly because of their scarcity [3]. The harvesting technique employed in the prevailing area is important in the conservation of medicinal plants as some of the practices may be destructive. In view of these threats to medicinal plants there is need for sustainable management, cultivation and conservation of medicinal plants [4]. According to[3], an important tool for local and international drug development and use to conserve the indigenous African medicinal plants. It is documented that 95% of drug needs in Africa come from medicinal plants, and as many as 5000 plant species in Africa are used for medicinal purposes [5; 1]. According to [6], one of the major concerns of our times is the loss of the Earth"s biological diversity. The absence of ecological knowledge implies hindrance to the conservation, management and sustainable use of medicinal plant species, especially in due to overexploitation and land use changes. Along with overexploitation, land use changes threaten many medicinal plant species in Africa [7]; [8]. Research has shown that medicinal plants with ruderal life history characteristics tend to be more tolerant of habitat disturbance and degradation [3].

Plants are used across the world for medical treatment, particularly in Africa. This study investigates and documents indigenous knowledge and use of medicinal plants among the Kuria communities in the Tarime and Serengeti districts of Mara Region, Tanzania. Ethnobotanical data were collected in collaboration with 20 Traditional healers (THs) aged between 30 and 85 years. The methods used were jungle-walk-and-identify, local field guides and observation, semi structured interviewers, focus group discussion with traditional healers, folk taxonomy, and scientific identification of plants. Kuria medicinal plant healers reported 100 medicinal plants belonging to 34 different families. Asteraceae family (15%) prevails, followed by Fabaceae (13%), and Lamiaceae (12%). Erect herbs constitute the largest fraction (41%), followed by shrubs (27%), trees (24%), grasses (4%), climbers (4%) and ferns (1%). Vines are not used as a medicinal plant despite their wide availability. Leaves are the most used parts of medicinal plants. Healers list about 53 different diseases treated with plants, the most common being abdominal pain (12.1% of plants) and urinary tract infections (10% of plants). Kuria medicinal plant healers have rich expert botanical and medicinal knowledge. An analysis of bioactive components in these medicinal plants is important for selection of medicinal plants to be used for drug development.

Indigenous knowledge on the use and conservation of medicinal plants by the Hehe ethnic group in the Udzungwa Mountains, Tanzania was documented through literature review, ethnobotanical survey, open-ended interviews, semi-structured questionnaires, village meetings and field observations. Twelve villages and 42 traditional healers were involved. At each village eight field transects were established. Eighty three medicinal plant species in 50 families were recorded. Medicines were extracted from one species or a mixture of several. Bark, roots, leaves, flowers, fruits and whole plants were used to prepare medicines. Traditional methods of conserving medicinal plants include social control of access (sacred groves), domestication, sustainable collecting and storage. Eastern Arc Mountains endemics are rarely used. Compared to other studies in the Eastern Arc Mountains, the number of overlapping medicinal plant species in different mountain blocks is less than 25% and those that do overlap are used for different purposes by various ethnic groups.
