BackgroundAn ethnobotanical study of medicinal plants was carried out in 14 villages adjacent to Mabira Central Forest Reserve (CFR) in Central Uganda between August 2013 and March 2014.MethodsInformation was obtained through interviews using semi- structured questionnaires. Field excursions with traditional healers and herbal medicine collectors were carried out. Descriptive statistics were used to present the data. Fidelity ratios and Informant consensus agreements were calculated.ResultsA total of 190 plant species in 61 families and 152 genera were reported in the treatment of various health conditions. Family Fabaceae was dominant representing 14 % of the plant species documented. Vernonia amygdalina was the preferred species for treating malaria. Leaves (68 %) were the most frequently used parts in preparing herbal remedies. Decoctions (29 %) and oral route (53 %) of administration were commonly used method of herbal medicine preparation and administration respectively. Fifty-eight health conditions grouped in 25 categories were treated using medicinal plants. Informant consensus agreement was highest for blood system disorders (0.9) that included anaemia, hypertension and blood cleansing indicating homogeneity of informant’s knowledge about remedies used. Vernonia amygdalina and Erythrina abyssinica had 100 % fidelity level for treatment of malaria and vomiting respectively.ConclusionThe diversity of medicinal plant species used and the associated indigenous knowledge are of great value to the local community and their conservation and preservation is paramount. The therapeutic uses of the documented plants provides basic data for further research focused on pharmacological studies and conservation of the most important species.

BackgroundPlants have been used as a primary source of medicine since ancient times and about 80% of the world’s population use herbal medicine to treat different ailments. Plant use knowledge differs in space and time and thus requires documentation to avoid its loss from one generation to another.MethodsIn order to accomplish the survey, semi-structured questionnaires were used. The data collected included names of plant species, parts used, ailments treated, growth habit, methods of preparation and mode of administration of the herbal remedies. Descriptive statistics were used to present the data in form of tables and a graph.ResultsResults showed that 50 plant species belonging to 26 families were utilized in the treatment of paediatric diseases of which Asteraceae and Lamiaceae were the most common. Leaves (80%) were the most commonly used and decoctions were the main method of preparation. Twenty nine health conditions were treated out of which digestive disorders, malaria and respiratory tract infections were predominant. Herbs and shrubs were equally dominant.ConclusionHerbal remedies are an important source of treatment for paediatric diseases in Buhunga Parish. However, there is need for collaboration between herbal medicine users and scientific institutions to help in the discovery of new drugs based on indigenous knowledge. Scientists ought to explore suitable methods of preparation and dosage formulations in order to achieve the best benefits from herbal remedies.

Background The global consumption of herbal medicine is increasing steadily, posing an extinction risk to medicinal plants. Uganda is among the top ten countries with a high threat of herbal medicine extinction, and Traditional Medicinal Knowledge (TMK) erosion. This might be attributed to the inadequate documentation, plus many more unclear hindrances. In this study, plant species used to treat human diseases in Butaleja district in Eastern Uganda and their associated TMK were documented. The conservation methods for medicinal plants were also evaluated. The rationale was to support the preservation of ethnopharmacological knowledge. Methods Data were collected from 80 herbalists using semi-structured questionnaires, from July 2020 to March 2021. Additionally, guided field walks and observations were conducted. Quantitative indices such as, use categories and informant consensus factor (ICF) were evaluated to elucidate the importance of the medicinal plants. Data were analyzed using STATA version-15.0 software. Results In total, 133 species, belonging to 34 families and 125 genera were identified. Fabaceae (65%), and Solanaceae (29%) were the dominant families. Leaves (80%), and roots (15%), were the commonest parts used in medicinal preparations; mostly administered orally as decoctions (34.6%) and infusions (16%). The commonest illnesses treated were cough (7.74%), gastric ulcers (7.42%), and malaria (4.52%). The informant consensus factor was high for all disease categories (≥ 0.8), indicating homogeneity of knowledge about remedies used. Only 73% of the respondents made efforts to conserve medicinal plants. The commonest conservation strategy was preservation of forests with spiritually valued species (100%), while compliance with government regulations was the rarest (4.5%). Overall, efforts to stop the extinction of medicinal plants and TMK were inadequate. Conclusion and recommendations There was enormous dependency on a rich diversity of medicinal plant species and TMK for healthcare and income generation. The potential for medicinal plant biodiversity loss was evident due to habitat destruction. Inclusion of traditional cultural norms in conservation strategies, and laboratory-based efficacy tests for the species identified are necessary, to promote the conservative and utilization of validated herbal medicines and TMK in rural settings.

Resource user surveys were conducted in 14 villages of Mabira central forest reserve. The study was intended to assess factors that encourage dependency on non-timber forest products (NTFPs). Understanding NTFP dependence is instrumental in guiding plans of forest use. The study was based on the hypothesis that forest income is more important to poor than wealthier households. Stratified random sampling was used to select NTFP users in different use categories per village. Information on household income of NTFP users was obtained using semi structured questionnaires and relative NTFP income was calculated. Binary logistic regression was used to analyse factors that influence NTFP dependence. 277 respondents used and sold a variety of products including; charcoal, firewood, fodder, construction materials, secondary products of NTFPs, medicinal and wild edible plants. Relative NTFP income was highest (53%) for poor households. 56% of households surveyed were dependent on NTFPs. Age, other income, household head, wealth quintile and distance from the forest significantly affected NTFP dependence. The high dependence on NTFPs is critical in development of management strategies that enhance conservation of the forest by focusing on women and the poor to avoid negative impact on their wellbeing.

Background: The use of medicinal plants in primary healthcare is central among rural communities in Uganda due to the expensive and often inaccessible conventional healthcare. Skin diseases pose a serious health risk given the challenge of HIV-AIDS whose opportunist infections manifest themselves as skin complications. The study investigated, identified and documented plant species used to manage skin infections, the plant parts used, methods of preparation and administration of herbal remedies.Methods: An ethnobotanical survey of medicinal plant species used to treat skin diseases was conducted in Katabi Sub-County, Wakiso District in Uganda using semi structured interviews. A questionnaire, checklist, and personal observation were the research instruments used. Descriptive statistics were used to present the data.Results: A total of 60 respondents were interviewed from 20 villages during this study. 50 plant species belonging to 29 families were documented. The highest proportion of species (25%) was used against fungal infections. Other proportions of plant species against their respective diseases were; 24%, 20%, 16% and 16% for allergies, wounds, skin rash and warts respectively and were inclusive of each other. Other mentioned diseases were treated by low proportions of plant species. The most frequently used plants were Psorospermum febrifugum (33%), Albizia coriaria (32%), Hoslundia opposita (37%), Justicia betonica (30%), and Euphorbia tirucalli (25%) Herbs (55%) were the main growth habit of medicinal plant species followed by trees (25%), shrubs (17%) and vines (2%) and grasses (1) Leaves (64%) were the most commonly used plant parts, followed by bark and roots (14% each), fruits (10%), flowers (8%), sap (5%) and pseudostem (2%). Fungal infections had the highest informant consensus factor (0.9) and Justicia betonica had the highest fidelity level (89%) for treatment of fungal infections. Topical administration to affected parts was the major method of administration at 54%. Other methods were oral, bathing, compresses, poultices and inhalation.
