Ethno medical knowledge and traditional use of Aristolochia bracteolata Lam. for malaria among local communities in Jubek State of South Sudan: A cross-sectional survey

Abstract

Ethnopharmacological relevanceThe recognized challenges to access conventional antimalarial medicines could have contributed to the extensive use of Aristolochia bracteolata Lam. (Aristolochiaceae)to manage malaria in South Sudan traditionally. However, the use and acquired experiences are notwell documented. Aim of the studyThis study aimed to document the traditional use of A. bracteolata for malaria treatment and experiences among the local communities in Jubek State of South Sudan. MethodsWe performed a cross-sectional study in four counties in Jubek State and interviewed 396 community members, including traditional healers, using a semi-structured questionnaire. Four focused group discussions (FGDs) were also conducted using the interviewer guide. The inclusion criteria were; adults 18 years and older, men andwomen participants, at least one year residing in the study area before the study, and those with a history of medicinal plant use. Data were summarized and presented as proportions. Qualitative data were analyzed using a thematic content approach. The major themes that emerged were discussed. We applied the Pearson Chi-Square test at α = 0.05 to test the study's significant differences in responses. The statistical package for social sciences version 21 software was used for data analysis. ResultsWomen accounted for 208 (52.5%) of participants, with the majority 321 (81.1%) were between 18 and 45 years. Interestingly, most 312 (78.8%) had formal education. Moreover, about 208 (52.5%) participants collect the plant in their vicinity, where leaves were the most commonly used part 277 (46.4%), followed by the roots, seeds, and stems at 245(41.0%), 71 (11.9%), and 4 (0.7%), respectively. Furthermore, about 63 (15.9%) of the participants experienced side effects, including early abortions, heartburns, sweating, and stomach discomforts. Conversely, a total of 387 (96.0%) reported getting cured of malaria. Generally, the quantity of medicine taken per day differs concerning parts of the plant, with leaves ranging from 1 to 10 pieces, roots at 0.4–1 g, and seeds at 0.1–0.5 g. The locals used these plant parts to prepare infusion and decoction traditional dosage forms for oral use. ConclusionThe documented medicinal plant's therapeutic uses provided critical information on the traditional use of A. bracteolata by the community in Jubek state of South Sudan to treat malaria. Although most users reported getting cured of malaria, a notable proportion of them experienced side effects, including early-stage abortion and stomach discomforts. Thus, the use of A. bracteolata preparations, particularly in pregnant women, should be avoided. Finally, further studies are needed to devise a strategy to neutralize the toxic compounds and create community awareness on best practices to minimize side effects.
