Background: 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. Methods: 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. Results: 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. Conclusion: 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.

The main objective of the study was to document plants species of medicinal value to the community in Minjar-Shenkora District and the associated knowledge on use, management, preparation and other aspects of the indigenous knowledge of the people in Minjar-Shenkora District. Methods: A total of 80 informants (60 males and 20 females) were selected to collect information on medicinal plant use from twenty sampled kebeles. Out of these, 40 key informants were purposively selected based on recommendation from elders and local authorities. Other40 informants were selected randomly. Ethnobotanical data were collected using semi structured interview, guided field walk, group discussion, preference ranking, use diversity ranking and market survey. Results: A total of 118 plant species distributed in 105 genera and 53 families were identified for their medicinal value. Out of the collected medicinal plants, about 48 (40.67%) plant species were shrubs, 46 (38.98%) were herbs and 16 (13.55%) were trees. Among the total traditional medicinal plants, 75 species were used against human ailments and 18 species were used for treatment of cattle diseases and 25 species for the treatment of both human and veterinary diseases. Ninety (76.27%) species of the medicinal plants were collected from the wild whereas 25 (21.18%) were from cultivated areas. Oral administration (54.21%) was found to be the dominant route of remedy administration. The medicinal plant species documented from the study area have also other uses including as firewood, construction and production of charcoal. Conclusion: Thus, most of these plants are found under threats in the study area, which is one of the main reasons for the decline of the associated knowledge. Therefore, documentation of the indigenous knowledge associated with the medicinal plants and their uses before losing them forever. Verification of the medicinal values of the frequently reported species through phytochemical and pharmacological studies are urgently needed actions.

Background: People's classification, management, and use of plants represent attempt to attracting people from different academic disciplines. Many countries use traditional medicine for their primary healthcare system. Medicinal plants have been important components of healthcare systems since the time immemorial. The objective of this research was to document and analyze traditional medicinal plants used by the Sheka people and associated ethnobotanical knowledge. Methods: Data was collected by administering pre-prepared semi-structured interview items to 414 informants. Market surveys, group discussion, and guided field walk were used. Data were analyzed using descriptive and inferential statistics; determination of informant consensus factor, fidelity level, as well as ranking and scoring. Results: A total of 266 plant species belonging to 192 genera and 74 families were identified. About 204 (77%) of the medicinal plants were used to treat human health problems. Only ten (4%) were used to treat livestock health problems and 52 (19%) of them were used to treat both human and livestock health problems. Croton macrostachyus, Prunus africana, Peperomia retusa, Lobelia giberroa, and Celosia schweinfurthiana were found to be high ranking medicinal plants against gastrointestinal problems based on simple preference ranking. Conclusion: Very high number of medicinal plant species recorded from the study area indicates that vegetation of Sheka is reservoir of medicinal plants. Hence, the area needs attention for medicinal plant conservation priorities. Plant parts used as medicines also play vital role in the entire medicinal plant life cycle. Therefore, it is useful to consider harvesting impacts. Except well-experienced traditional healers, people of the study area use the medicinal plants haphazardly. There may be high risk of being victims of dosage and improper usage. High ranking medicinal plants are candidates for further phytochemical profiling, drug research, and development.

This study was conducted in four districts of Amhara Region, Ethiopia. The aim of the study was to assess medicinal plants found in Menz gera, Siyadebirna Wayu, Antsokiya gemza and Bugna districts, Amhara region, Ethiopia. The ethnobotanical surveys were carried out from September 2017 to June 2018 using a semi-structured checklist consisting of questions or issues prepared in advance. Two separate questionnaires were prepared, one for the local healers and the other for the local community. A total of 376 (94 per district) informants were selected using purposive sampling technique and asked both open and close-ended questions. The interviews and observations were based on and around this checklist and some issues were raised promptly depending on responses of an informant. All plant species found in each district were recorded, collected, pressed and identified following Flora of Ethiopia and Eritrea. From the total 376 informants 238 were males and the rest 138 were females. A total of 77 medicinal plants were reported and distributed in 28 families. Family Lamiaceae was distributed in all four districts followed by 5 families which were distributed in three districts. Leaf 47 (56.63%) was the plant part widely used followed by stem 12 (14.46%), root 8 (9.64%) and seed 7 (8.43%), while the rest include fruit 3 (3.61%), bulb 3 (3.61%), flower 1 (1.20%). Ocimum lamiifolium Hochst. and Citrus durantifolia were the plants with the highest fidelity level values, each scoring 100%, followed by Moringa stenopetala (Bak.f.) Cuf. (96%). From the present study, the highest number of medicinal plants was observed in Antsokiya Gemza District followed by Siyaderina wayu, Bugna and Menz Gera, with 29, 24, 15 and 9 number, respectively. In these four districts the highest number of plants was used to treat wound followed by abdominal disease/pain. Pounding and grinding of the plant parts to make a powder were the most frequently used methods of traditional medicine preparation. Traditional medicine is the base for the modern medicine, but nowadays, the work is not respected by most people so it needs further attention especially in changing the attitude of the community towards traditional medicine.

This study recorded medicinal plants used by ethnic people of Gechi District, Buno Bedele zone of South West Oromia region, Ethiopia. Data were collected from 386 informants through semistructured interviews, guided field observations, and focus group discussions. Descriptive statistics and quantitative ethnobotanical indices were used to analyze the data. Moreover, an independent t-test and one-way ANOVA were employed to investigate the effect of Sociodemographic traits on traditional medicinal knowledge. The study documented 70 medicinal plant species belonging to 61 genera and 36 families. Most plants (83.7%) were used to treat human ailments. Asteraceae (7 species) mainly represented the family. Most of the plants collected were shrubs (32.9 %), followed by herbs (25.7%). Leaves (42.3%) represented the highest part for remedy preparation. The dominant route of administration of remedies was oral (56%). Jaccard's similarity index (JI) showed a high degree of similarities (JI = 0.75-0.91) among three kebeles namely, Imboro, Koba, and Dike. The highest Informant consensus factor (ICF) value (0.73) was detected for the sensory organs category illnesses. Juniperus procera Hochst. Ex. Endl. was observed with the highest fidelity level (FL) index value (0.97) for the wound. The highest preference ranking (PR) was adjudged to be Ruta chalepensis L. for stomach ache. Syzygium guineense (Willd.) DC. was top-ranked as a multipurpose plant in direct matrix ranking (DR). It was observed that the Traditional Knowledge (TK) of medicinal plants was significantly (P<0.05) influenced by the gender, age, and educational level of the people. Therefore, our documentation of TK on medicinal plants possessed by the people of the studied area could help preserve their knowledge for extensive use.

In Ethiopia, traditional knowledge associated with medicinal plants are being seriously depleted due to deforestation, environmental degradation and acculturation that have been taking place. The present study documented traditional knowledge associated with medicinal plants in Decha (Keffa) and Sheybench (BenchMaji) districts of Southern Nations, Nationalities and. The objective of the study was to identify and record traditional knowledge and practices associated with the medicinal plants with special emphasis on plants with potential for bio-prospecting. The study method was interviewing selected herbal practitioners and elderly people by means of a semi-structured questionnaire and focus group discussion. Out of 146 species of medicinal plants collected from the study area, herbs (41.4%) and shrubs (35.5%) constituted the highest proportion, followed by trees (16.2%) and climbers (6.9%). Out of the total of 146 medicinal plants collected 95(64.7%) were used against human disease, 32(21.9%) of medicinal plants were used against animal disease and the remaining 18% were used for the treatment of both human and animal diseases. The results showed relatively a higher proportions of plant species were found to be used for the treatments of respiratory diseases (32.8%), followed by for the treatment of miscellaneous disease conditions such as swellings/tumors, toothache, headache, etc. (20.9%), and gastrointestinal related complaints (18.4%). The most frequent methods (95.7%) of preparation of plant medicines in the studied communities were squashing/grinding of plant parts and extracting juicy ingredients. Although there is wealth of medicinal plants and traditional knowledge that has been applied in the treatment of human and lifestalk health problems, the sustainability of these heritages has been challenged increasingly by human and environmental factors. According to some respondents the traditional medicinal practices has been discouraged by modern health care system due to fear of inappropriate dosage and safety issue. Therefore in addition to documenting traditional medicinal plants and the associated knowledge, it is important to test the scientific validity of the herbal preparations to establish appropriate dosages and conduct clinical studies to ensure the safety of the traditional medicines if we are to benefit sustainably from these heritages.

Background: Plant-derived products have an imperative biological role against certain pathogenic organisms and were considered to be a major source of modern drugs. Rural people residing in developing countries are relying on traditional herbal medical system due to their strong believe and minimum access to allopathic medicines. Hence, ethnomedicinal knowledge is useful for the maintenance of community's based approaches under this medical system. Present study was carried out in an unexplored remote tribal area of Pakistan to investigate and document the existing ethnomedicinal knowledge on local flora. Methods: Data was collected through semi-structured questionnaires from the community members and local herbalists. Use reports (URs) were counted for each species and analyzed through Linear Regression between the number of URs per family and number of plant species per family. Results: A total of 64 medicinal plant species were recorded belonging to 60 genera and 41 families. Most frequently used plant families in ethnomedicines were Lamiaceae (8 species) and Asteraceae (7 species). Highest URs were recorded for Caralluma tuberculata N.E. Br. (49 URs) being followed by Thymus serphyllum L. (49 URs), Fagonia cretica L. (47 URs), Plantago lanceolata L. (45 URs), Periploca aphylla Decne. (44 URs), Citrullus colocynthis (L.) Schrad. (44 URs), and Sideroxylon mascatense (A.DC.) T.D.Penn. (44 URs). New ethnomedicinal uses were reported for Boerhaavia elongata Brandegee and Fumaria officinalis L. with confidential level of URs from the study area. Nineteen groups of health conditions were recorded during the course of study being treated with medicinal plants. Maximum number of 30 plant species was used to treat digestive problems. Most widely practiced mode of drugs' preparation and administration was powder. Leaves (30% plants) were the most frequently used plant parts in the preparation of ethnomedicinal recipes. Conclusions: Current study is an important addition to the field of ethnomedicines. The study reports important medicinal plants from an area, which has not been investigated previously. Traditional knowledge is restricted to health practitioners and elder community members. This knowledge is at the verge of extinction because younger generation is not taking interest in its learning and preservation process. Hence, there is a dire need to phytochemically and pharmacologically test the investigated taxa for the validation of traditional knowledge.

Background: Assosa District is home to variety of medicinal plants and associated indigenous knowledge where there was no previous study on medicinal plants. The study was aimed at documenting the medicinal plants and associated knowledge emphasizing structure and relationships among plants and humans. Methods: About 58 regular and 18 healers were selected from nine sites based on availability of vegetation, healers and accessibility. Ethnobotanical techniques and indices were used for data collection and analysis supplemented by statistical tests, models and ordination methods. To display the structure of relationships among plants and humans, R Statistical Software was used. Results: About 54 medicinal plants belonging to 49 genera and 33 families were identified. Family Solanaceae was with the highest number of species. Most of the medicinal plants were shrubs, followed by trees. Leaves were the most frequently used parts. About 64% of the remedies were prepared fresh. The highest fidelity level (100%) was recorded for hemorrhoids and gastric ulcers. The highest informant consensus factor values (0.96) were linked to diseases of the eye and adnexa. Deforestation and urbanization were among the major threats to conservation. Significant associations among medicinal plant knowledge and sociodemographic factors observed. Conclusion: There is rich medicinal plant diversity and associated indigenous knowledge demanding ex-situ and in-situ conservation. Phytochemical profiling of high-ranking medicinal plants for cupping therapy and other health problems is needed. Ordination methods are good representations of the structure of relationships among plants and humans.

This study was conducted in Menz Gera Midir (Ethiopia) to document medicinal plants and related indigenous knowledge of local people. Data were collected from 72 (12 of them key) informants using semi-structured interview, group discussion and guided field walk. Priority ranking, paired comparison and direct matrix ranking were used in data analysis. A total of 155 medicinal plant species, 104 (67.1%) from natural vegetation and 51 (32.9%) from home gardens were collected. From the total species, 115 were reported to cure only human diseases, 10 species for livestock ailments and 30 for both. Asteraceae contributed 16 species and ranked first followed by Lamiaceae with 12 species. Frequently used plant parts were leaves (43.9%) and roots (31%). The recurrent mode of preparation was pounding (27.9%) followed by powdering (16%) and mostly administrated through oral drinking (33%) and dermal cream (15.7%). Paired comparison revealed that Cucurbita pepo was the most preferred species to treat headache. However, Olea europaea subsp. cuspidata was reported as the most multipurpose plant species. Priority ranking indicated that Lupinus albus was the rarest medicinal plant in the study area. The medicinal plant resources of the area were threatened by agricultural expansion, charcoal making, firewood collection and overgrazing.
