Background: Traditional knowledge on the use of medicinal plants is in danger of extinction because of different changes taking place all over the world including Ethiopia and thus there is a need for its immediate documentation for the purpose of conservation, sustainable utilization and development. Thus, an ethnobotanical study was conducted in Ambo District, Oromia Regional State of Ethiopia to document and analyze local knowledge on medicinal plants used for the treatment of animal diseases.Methods: Data were collected between November, 2017 and April, 2018 mainly through semi-interviews conducted with purposively selected informants. Data collected mainly included demographic information of respondents, local names of medicinal plants, plant parts used, preparation methods, mode of applications, diseases treated, and habit and habitat of the reported plants. Based on data obtained through interviews, Informant Consensus Factor (ICF) values were computed.Results: A total of 55 medicinal plants used to manage livestock ailment were reported by informants in the Ambo District. Herbs were commonly used in the preparation of remedies. Leaf was the most frequently utilized plant part accounting for 49.1% of the total reported medicinal plants. The majority (69.0%) of the medicinal plants used in the study District were uncultivated ones mainly harvested from edges of forests and bushlands, roadsides, river banks and grasslands. High ICF values were obtained for ophthalmological (0.82), dermatological (0.79), febrile (0.77) and gastro-intestinal ailments (0.77).Conclusion: The current study shows that there is still rich traditional knowledge on the use of plants to control various animal diseases in study District. However, such claim needs to be scientifically verified with priority given to medicinal plants used in the treatment of ailment categories with high ICF values as such plants are considered to be good candidates for further pharmacological evaluation.

“…Forests of Uíge Province in northern Angola are full of high value NWFPs, including Dracaena camerooniana Baker, a wild vegetable appreciated by the local population, and an additional source of financial income for subsistence farmers and hunter-gatherers. Furthermore, they constitute a reservoir of firewood for heating [8], handicrafts [8,9], building materials and furniture [8], instruments of music folkloric and religious [8]; edible [8,9], medicinal plants [8,9], rituals [9] and wild animals [8].…”

Aims: The aim of this research was to contribute to the survey of ethnobotanical knowledge on the use of Dracaena camerooniana by the local communities’ bordering the tropical forests of Uíge province. Study Design: The data collections were carried out using the semi-structured interview method. The approch methods are an ethnobotanical and socio-economics surveys populations of the study area. Place and Duration of Study: The study was undertaken in the province of Uíge, Republic of Angola, from April 2016 to March 2018, period that covers the dry and rainy season. Methodology: The surveys consisted in drafting a questionnaire beforehand to apprehend the knowledge and multiples uses of D. camerooniana among the surrounding population. The interview were conducted in Kikongo language and in Portuguese according to the mastered by the people surveyed. Results: The findings show that tropical forest zones of Congolese guinea/Zambian located in Uíge Province, is full of high value non-wood forest products (NWFPs) including D. camerooniana Baker (locally called Nzala bakala or Nsala bakala). This plant species is a wild green vegetable essence appreciated by the local population and is an additional source of financial income for subsistence farmers and Hunter-gatherers. Knowledge of D. camerooniana consumption was transmitted from generation to generation by oral tradition. The study also shows that D. camerooniana is well known and used by the local communities of Uíge. Finally, the consumption and commercialization of NWFPs, such as the leaves of D. camerooniana contribute in strengthening nutrition, health, food diversity, income and livelihoods. Conclusion: Despite its importance in food security and socioeconomic terms in both rural and urban areas, few scientific researchers have been fully interested in its valorization. In addition, the phytochemical studies should be carried out to discover the nutritional, toxic, and medicinal properties of this plant.

“…These values are low when compared to e.g. the ICF-value (0.71) reported by Ngbolua et al [58] to treat sexual weakness in Kinshasa or by Lautenschläger et al [17] for treatment of intestinal parasitosis (ICF: 0.48), rheumatism (ICF: 0.47) and otitis (ICF: 0.4) in northern Angola in Uíge Province. Low ICF-values could be probably due to the tendency of phytotherapists to keep their knowledge secret from others [59,60].…”

“…They are to be prioritized for both cultivation and conservation to prevent their disappearance. Heinrich et al [16] and Lautenschläger et al [17] suggested that informant consensus factor (ICF) is a good indicator for selecting plant species best adapted to pharmacological needs and to be subjected to phytochemical analysis.…”

Background: The phytotherapeutic knowledge of the Kongo people in the terroirs of Kisantu and Mbanza-Ngungu in Kongo-Central Province (DR Congo) is rapidly eroding. To document the remaining knowledge, we conducted an ethnobotanical survey on the most important medicinal plant species and diseases treated with them, as well as plants with therapeutic potential. We also verified how medicinal knowledge differs between different social groups.Method: From June 2017 until February 2018 and from February until April 2019, we conducted a survey with 188 phytotherapists, selected using the snowball method and surveyed using semi-structured interviews. Voucher specimens were taken for identification. Ethnobotanical database was analyzed using medicinal Use Value (UVs), Informant Agreement Ratio (IARs), Informant Consensus Factor (ICF) and Species Therapeutic Potential (STP). Medicinal knowledge between different social groups was analyze using non parametric tests and the Poisson regression. Results: A total of 231 plants (i.e. 227 botanical species, representing 192 genera and 79 families) were reportedly used to treat 103 diseases. Most abundant taxa were reported for the Fabaceae family (11.9 %) and genus Solanum (1.8%). Most harvested species (45,0%) were from anthropized areas. Most frequent plant part, botanical form, preparation and administration method were leaves (39.4%), herbs (37.1%), decoction (41.7%) and oral ingestion (72%) respectively. Four of all inventoried species showed high UV S (> 0.05), whereas 8 had an IAR of 1. According to respondent consensus on plant use, 31 diseases were mentioned. Highest ICF (≥ 0,4) were observed for hemorrhoids (0.44), amoebiasis (0.43) and itchy rash (0.42). Fifty-four plant species were identified likely to have interesting therapeutic potential. Analysis of medicinal knowledge showed that the mean number of reported species and diseases vary considerably depending on gender, type and location of therapists (P < 0.05). Conclusion: Results prove that the Kongo phytopharmacopoeia makes use of interesting medicinal plant species that could be further studied for conservation and pharmacological applications.
