Ethnomedicinal Knowledge of Plants Used in Nonconventional Medicine in the Management of Diabetes Mellitus in Kinshasa (Democratic Republic of the Congo).

Background: People with diabetes, herbalists, and traditional medicine practitioners (TMPs) from Kinshasa use plants to treat diabetes, but no study has inventoried the plants used by these populations. The present study was conducted to identify the plants used in Kinshasa to treat diabetes mellitus. Methods: The survey conducted in the form of a semistructured interview between March 2005 and August 2006 made it possible to collect ethnobotanical information from people with diabetes (n = 126), herbalists (n = 80), and TMPs (n = 120). Results: The 326 subjects consulted (sex ratio M/F = 0.6, age 51 ± 7 years, and experience: 17 ± 5 years) provided information on 71 plants, most of which are trees (35%), belonging to 38 families dominated by Fabaceae (19.7%) and indicated in 51 other cases of consultation dominated by malaria (12%). From these 71 plants derived, 86 antidiabetic recipes were administered orally, where the leaf is the most used part (>50%) and the decoction (>46%) is the most common mode of preparation. This study reports for the first time the antidiabetic use of 11 species, among which Tephrosia vogeliiX (0.08), Chromolaena corymbosaX (0.06), and Baphia capparidifoliaX (0.06) present the highest consensus indexes (CI) and Marsdenia latifoliaW (UVp = 0.08) and Rauvolfia manniiX (UVp = 0.06) present the highest UVs. Conclusion: The results show that Kinshasa people treat diabetes using several plants. Some are specific to the ecological environment; others are used in other regions. Pharmacological studies are underway to assess the therapeutic efficacy of these plants.

[Evaluation of self-medication practices and their characteristics among Uvira in Democratic Republic of Congo students]. / Evaluation des pratiques de l'automédication et leurs caractéristiques auprès des étudiants d'Uvira en République Démocratique du Congo.

Introduction: self-medication poses a threat to public health. The purpose of this study was to evaluate self-medication practices among Uvira students in the Democratic Republic of the Congo (DRC). Methods: we conducted a cross-sectional descriptive study based on an indirect interview of 700 students, using a self-administered survey questionnaire. Data were processed using XLSTAT. Results: according to the survey conducted on these 700 students, the prevalence of self-medication was 99.3% (n=695), of which 42.3% (n=294) started during adolescence. Of the total respondents, 57.4% (n=399) said they resorted to self-medication every time they fell ill and were short of money (n=471, 67.7%) for a consultation. The most commonly cited pathology encountered during this practice was malaria (n=212, 30.5%). Of all drugs used, paracetamol was in the first place (n=106, 15.3%) while the tablet was the form most used by these students (n=598, 86%). In terms of the drug combination, Fansidar-Coartem (n=106, 17.2%) was the most common; the dosage was age-dependent in 65.6% (n=456) of cases. This study also showed that 37.4% (n=695) of the students interviewed used phytotherapy, mainly to treat malaria (n=124, 47.3%). Conclusion: among Uvira students, self-medication is extremely used, especially against malaria. Efforts must be made by healthcare personnel in collaboration with policymakers to raise awareness about the rational use of medications, in order to better control and potentially eradicate this practice that is harmful to health.
