This paper reports an ethnobotanical study that focused on the traditional medicinal plants used by local communities to treat human and livestock ailments. A cross-sectional study was undertaken from September 2009 to June 2010 in Wayu Tuka District of Oromia Region, Ethiopia. The aim of the study is to document medicinal plants used by local people of the study area and the threats currently affecting medicinal plants.
Ethnobotanical data were collected using semi-structured interviews, field observations and group discussion in which 63 (41 men & 22 women) randomly selected informants participated. Of which, 11 (10 male and 1 female) were local healers. Paired comparison method, direct matrix ranking and Informant consensus factors (ICF) were used to analyze the importance of some plant species.
A total of 126 medicinal plant species, distributed in 108 genera and 56 families, were collected together with their medicinal uses. Of the 126 species of medicinal plants collected from the study area, eighty six (68%) were obtained from the wild whereas thirty three (26%) were from homegardens. The Fabaceae came out as a leading family with 15 medicinal species while the Solanaceae followed with eight species. Seventy eight (62%) of the medicinal plants were reported as being used for treating human ailments, 23 (18.2%) for the treatment of livestock ailments and 25 (20%) for both. The most frequently used plant parts were leaves (43%), followed by roots (18.5%) while crushing, which accounted for (29%) and powdering (28%) were the widely used methods of preparation of traditional herbal medicines.
The number of reported medicinal plants and their uses by the local people of the District indicate the depth of the local indigenous knowledge on medicinal plants and their application. The documented medicinal plants can serve as a basis for future investigation of modern drug.

    ABSTRACT: .Background: Medicine is one of the four basic needs of human being fulfilled by the plant up to a large extent. Herbal remedies have been an integrated part of healing and are considered to be the oldest form of healthcare known to mankind on this earth. Materials and methods: An ethno botanical survey has been conducted using semi structured interview schedule with the villagers, in agro forestry system to identify the traditionally used plants. Results: A total of 60 medicinal plants belonging to the 33 families were found to be used for the treatment of diseases. Out of 33 families, Cucurbitaceae contributed maximum 06 genera followed by Poaceae, Brassicaceae, Solanaceae and Apiaceae. The documented plants were listed as 32 herbs, 06 shrubs, 15 trees and 07climbers. Different parts of investigated plants such as leaves (34%), fruits (19%), bark (only 2%) etc. were useful to cure the 10 different categories of ailments. In this study, about 70% of the medicines were prepared by fresh plant parts. The mode of application of herbal medicines was oral (53.33%), dermal (10%) and rest (36.66%) taken both by oral and dermal. Conclusions: Indigenous people still believe in traditional system of medicine and prefer it in search of primary health care. Such plants may be used in the formulation of new drugs. The agroforestry system supports the ethno-botanical values in a very extensive way. It is one of the best known traditional practices to cure and prevent the diseases from the very beginning of civilization, other than to full fill the daily requirement of food, fodder and timber production. The remedies obtained from the agroforestry and home gardens system are comparatively cheaper, pure, have no side effects and easily available. Therefore, it deals with those communities whom have the limited access to mainstream medicine. Agroforestry provides the alternative source of remedies and growing space for medicinal plant. Hence, there is a great a need to cultivate and conserve such plants and atthe same time, there is an immediate need of indigenous practices, knowledge of such plant resources, and documentation.

    ABSTRACT: Traditional medicines have been used for nearly 90% of livestock populations in Ethiopia where complimentary remedies are required to the modern health care system. All plants with pharmacological activity complimentarily prescribed as best choice against livestock diseases. A community based cross - sectional survey was conducted to investigate ethno-veterinary knowledge and practices of study area by purposive sampling techniques. The data from respondents were collected through face-to face interview using pre-tested semi-structured questionnaires, which was further accompanied by field observations of the medicinal plants. The vast majority of the statistics were analyzed descriptively by SPSS 16 Windows version to extrapolate our findings in ethno-botanical knowledge. In the study, a total of 74 species of ethnoveterinary medicinal plant species from 31 families have been identified for treating 22 different livestock ailments. The three families: Asteraceae, Cucurbitaceae and Solanaceae make up larger proportion of reported medicinal plants which accounted for 10.41%, 8.33% and 6.25%, respectively. Of reported medicinal plants, 16.7% informant consensus was recorded for the species Croton macrostachyus Del., 10.7% for Nicotiana tabacum L. and 9.5% for Olea capensis L.Subsp. macrocarpa (C.H. Wright) I.Verd. in treatment of one or more veterinary ailments. The greater varieties of medicinal plant species that accounted for 28.2% were used against management of blackleg which was common livestock diseases in the study area. The findings showed, trees accounted for 43.24%, followed by shrubs (33.78%) and herbs (14.86%). Eighty one percent of medicinal plants reported by respondents were collected from wild habitats, and leaves reported to be used by 68% of the informants for ethnoveterinary medicines preparations. The preparations were applied through different routes of administration; oral administration accounted for (76.2%), followed by application of topical (9.53%) and nasal (5.19%). Ethnoveterinary practices significantly suggested to play greater roles in livestock health care as an alternative or integral part of modern veterinary practices. The traditional knowledge in treatment of livestock diseases of Jimma Zone needs further scientific evaluations by phytochemical and antimicrobial experimentation to determine safety, efficacy, mode of delivery, drug development and dosage in pharmacological laboratory.

    ABSTRACT: Traditional medicines remained as the most affordable and easily accessible source of treatment in the primary health care system among diverse communities in Ethiopia. The Oromo community living in the prehistoric Harla and Dengego valleys has long history of ethnomedicinal know-how and practice against human and livestock ailments. However, this rich ethnomedicinal knowledge had been remained unexplored hitherto. This study focus on the comprehensive ethnomedicinal investigation in an attempt to safeguard the deteriorating ethnomedicinal knowledge that can be used as a steppingstone for phytochemical and pharmacological analysis. Fifty five (44 male and 11 female) systematically selected informants including ten traditional herbalists (key informants) were participated in the study. Semi-structured interviews, discussions and guided field walk constituted the data collection methods. Factor of informant consensus (Fic), frequency of citation (F%), and binomial test were employed in data analysis. Medicinal plant specimens were collected, identified and kept at Haramaya University Herbarium (HHU). A total of 83 traditional medicinal plant species against human ailments in 70 genera and 40 Families were recorded. Twelve medicinal plants were marketable in open market places of the nearby towns. Formulations recorded added to 140 remedies for 81 human ailments. Concoction accounts 50.7% of the total preparations followed by fluids extraction (10.7%) and infusion (6.4%). Fifteen different plant parts were used for remedies preparation wherein leaves accounted 46.4%, stem 9.2%, fruits and roots each 7.8%. Most of the remedies (90.7%) were prepared from single plant species like, aphrodisiac fresh rhizome of Kleinia abyssinica (A. Rich.) A. Berger chewed and swallowed few hours before sexual performance for a man having problem of erectile dysfunction. The Fic value ranges between 1.0 (gastritis and heartburn/pyrosis) and 0.77 (swollen body part). Aloe harlana Reynolds was reported to be used for the highest number of ailments treating swollen body part locally called GOFLA, colon cleaner, snake bite, liver swelling, spleen swelling/splenomegaly, fungal infections and inflammation of skin. Such documentation of comprehensive ethnomedicinal knowledge is very valuable and needs to be scaled-up so that it could be followed up with phytochemical and pharmacological analyses in order to give scientific ground to the ethnomedicinal knowledge.
