Ethnomedicinal plants used for malaria treatment in Rukungiri District, Western Uganda

Abstract

Background Malaria remains a major global health challenge and a serious cause of morbidity and mortality in sub-Saharan Africa. In Uganda, limited access to medical facilities has perpetuated the reliance of indigenous communities on herbal medicine for the prevention and management of malaria. This study was undertaken to document ethnobotanical knowledge on medicinal plants prescribed for managing malaria in Rukungiri District, a meso-endemic malaria region of Western Uganda. Methods An ethnobotanical survey was carried out between May 2022 and December 2022 in Bwambara Sub-County, Rukungiri District, Western Uganda using semi-structured questionnaire. A total of 125 respondents (81 females and 44 males) were randomly selected and seven (7) key informants were engaged in open interviews. In all cases, awareness of herbalists on malaria, treatment-seeking behaviour and herbal treatment practices were obtained. The ethnobotanical data were analyzed using descriptive statistics, informant consensus factor and preference ranking. Results The study identified 48 medicinal plants belonging to 47 genera and 23 families used in the treatment of malaria and its symptoms in the study area. The most frequently cited species were Vernoniaamygdalina, Aloevera and Azadirachtaindica. Leaves (74%) was the most used plant organ, mostly for preparation of decoctions (41.8%) and infusions (23.6%) which are administered orally (89.6%) or used for bathing (10.4%). Conclusions Indigenous knowledge of medicinal plants used as prophylaxis and for treatment of malaria still exist among the local communities of Bwambara Sub-County. However, there is a need to investigate the antimalarial efficacy, phytochemical composition and safety of species (such as Digitariaabyssinica and Berkheyabarbata) with high percentage use values to validate their use.

“…In contrast, infusions are consumed within a day, while decoctions are stored in tightly sealed containers for at least 1 week at room temperature. However, this finding contrasts with other research conducted in Uganda and the broader East African and African regions, where decoction is frequently identified as the dominant method of herbal preparation ( Alebie et al, 2017 ; Gumisiriza et al, 2023 ). Decoctions may be preferred when the part of the plant used is available all year round such as leaves and bark.…”
