Abstract: ABSTRACT An ethnobotanical study of medicinal plants was conducted between September 2009 and March 2010 in Ada’a Wereda, Eastern Shewa Zone of Oromiya Regional State of Ethiopia. The objective of the study was to identify and document medicinal plants and associated indigenous knowledge. The usual ethnobotanical methodologies were applied during the course of the study. A total of 105 informants were chosen from 15 study kebeles (7 informants per kebele) yielding a total of 292 plant species. These were distributed across 202 genera and 72 families. Of these species 131 (44.30%) were reported to have medicinal value. These medicinal plants were distributed along 109 genera and 54 families. Most of these plants were collected from the wild. The leading plant families to encamps large medicinal species were the Lamiaceae (10.69%) followed by Asteraceae (9.16%) and Solanaceae (5.34%). About 77 different kinds of disease that were perceived by the local people were identified. Among the identified plants most of them (64%) were used to treat human ailments, and about 21% used to treat both human and livestock’s’ ailments whereas only few (15%) were reported for treating livestocks ailments alone. The most frequent lifeforms of the medicinal species were shrubs (38.93%) followed by herbs (36.64%) and trees (16.79%). The most utilized plant parts for traditional drug preparation were reported to be roots (38.34%) followed by leaves (33.68%) and fruit (6.22%). Most of the preparations used fresh parts (57%) more than the dried forms (41%). The most common route of application was oral (50.27%) followed by dermal (37.43%). Most of the diseases known in the Wereda were the results of poor sanitation. The local conditions of remedy preparation do not favour hygienic measures, leaving much to be desired. Diagnosis involves simple inspection of the patients, and prescribed doses lack standardizations. Medicinal plants were claimed to be getting lost from time to time. Inappropriate methods of harvesting roots and barks (uprooting and debarking) and over use were among the common experiences for remedy preparation, which perhaps result in the death of the mother plants. This study shows that most medicinal plants were obtained from riverine and wet areas which prompt a need for real conservation of such ecological units. Negative attitudes prevail among people about the traditional practices. On top of this, many practitioners are less willing to share their knowledge and skills. Therefore, special attention towards conservation of medicinal plants and the associated indigenous knowledge shall be an immediate task of any concerned body.
