Ethnobotanical study of medicinal plants in Sekela District, northwestern Ethiopia

Abstract

BackgroundPeople in Sekela District, like others in Ethiopia, have a long tradition of using medicinal plants to treat human and livestock ailments. However, medicinal plants and their associated indigenous knowledge are currently under threat. Thus, the study was carried out to compile ethnobotanical knowledge about medicinal plants in the district. MethodsA total of 352 informants from six study sub-districts (328 general and 24 key informants) were selected randomly and purposefully. Individual interviews, focus group discussions, guided field walks, and market surveys were used to acquire ethnobotanical data using semi structured interview questions. The informant consensus factor (ICF), fidelity level, preference ranking, direct matrix ranking, medicinal use, and Analysis of Variance were used. ResultsA total of 121 medicinal plants belonging to 106 genera and 55 families were documented. The Asteraceae family had the most species with 11 (9 %), followed by Lamiaceae with 8 (6.6 %), while leaves were the most utilized part with 56 (37 %). The majority of the remedies were made as a concoction (32, 17 %) and delivered orally (98, 57 %). There was a statistically significant difference in indigenous knowledge on medicinal plants among genders, ages, marital status, educational levels, and occupations (p ˂ 0.05). The dermatological disease categories had the highest ICF (0.92) in human ailments. ConclusionThe study revealed that Sekela District is rich in medicinal plants for treating human and livestock ailments, and has indigenous knowledge to utilize these resources effectively. However, overgrazing, agricultural expansion, and improper harvesting techniques threaten medicinal plants. This signals the need to make significant efforts to raise public awareness about their conservation and sustainable use.
