Résumé :

Ethnopharmacological relevance: The main objective of the present study was to collect and gatherinformation on herbal remedies traditionally used for the treatment of malaria in Bukavu and Uvira, twotowns of the South Kivu province in DRC.Material and methods: Direct interview with field enquiries allowed collecting ethnobotanical data; foreach plant, a specimen was harvested in the presence of the interviewed traditional healers (THs). Therecorded information included vernacular names, morphological parts of plants, methods of preparationand administration of remedies, dosage and treatment duration. Plants were identified with the help ofbotanists in the herbaria of INERA/KIPOPO (DRC) and the Botanic Garden of Meise (Belgium), wherevoucher specimens have been deposited. The results were analysed and discussed in the context ofprevious published data.Results: Interviewees cited 45 plant species belonging to 41 genera and 21 families used for the treatmentof malaria. These plants are used in the preparation of 52 recipes, including 25 multi-herbal recipes and27 mono-herbal recipes. Apart of Artemisia annua L. (Asteraceae; % Citation frequency = 34 %) andCarica papaya L. (Caricaceae; % Citation frequency = 34 %), the study has highlighted that the mostrepresented families are Asteraceae with 12 species (26 %), followed by Fabaceae with 7 species (16 %)and Rubiaceae with 4 species (9 %). For a majority of plants, herbal medicines are prepared from theleaves in the form of decoction and administered by oral route.Conclusion: Literature data indicate that part of cited species are already known (38 %) and/or studied (30%) for antimalarial properties, which gives credit to the experience of Bukavu and Uvira interviewees andsome level of confidence on collected information. The highly cited plants should be investigated indetails for the isolation and identification of active ingredients, a contribution to the discovery of newpossibly effective antimalarials.
