Ethnobotanical study of medicinal plants of lake Abaya basin, southern Ethiopia

Abstract

IntroductionEthnobotanical study was conducted in lake Abaya basin, southern Ethiopia. The study aimed at documenting indigenous and local knowledge and use of traditional medicinal plants for treating human and livestock ailments. MethodsA survey was conducted among purposively selected traditional healers and randomly selected herbal medicine practitioners of the local communities. Guided field observations, semi-structured interview, group discussions and market survey were used for ethnobotanical data collection. Preference and direct matrix rankings including descriptive and inferential statistics were used to analyse the data. ResultsSeventy-one medicinal plant species belonging to 64 genera and 36 families were used as remedies for human and livestock ailments. Among these, 51 were reported for human, 13 for livestock ailment treatments and seven for both. Most of them were collected from the wild. The most frequently used plant parts were leaves followed by roots. The largest numbers of remedies were used to treat abdominal disorders. The major routes of administration include oral, dermal and nasal. Leucas abyssinica ranked first and most effective to cure abdominal disorder followed by Lepidium sativum and Stephania abyssinica. Moringa stenopetala was most preferred multipurpose plant by local people. Agricultural expansion was the major threatening factor followed by firewood consumption. ConclusionsTraditional healers apply diversified traditional medicinal plants for healthcare of the community and domestic animals. However, traditional medicinal plants and the associated indigenous knowledge of local community were under threat. Thus, public awareness and community-based management need to be encouraged to maintain indigenous ethnomedicinal knowledge of the study area.
