Introduction: Women become vulnerable to certain pathologies during pregnancy in rural areas and the use of traditional pharmacopoeia using medicinal plants is the solution often adopted. This article focuses on the use of medicinal plants among pregnant indigenous Batwa women living around the Kahuzi Biega National Park (KBNP). The knowledge and practices of these women have enabled us to inventory and determine the different uses of these plants.Methodology: The data used in this study was collected by means of an ethnobotanical survey conducted using a questionnaire following the semistructured interview method. The data collected, which included ethnobotanical characteristics, were processed and analyzed with appropriate ethnobotanical and statistical software in order to select a few plants for future laboratory testing.Result: Most of the traditional practitioners interviewed were women (83.88%) and a large proportion of them (35%) were over 65 years of age. The plants used were classified according to the different stages of pregnancy development. Thus, Dichrocephala integrifolia, Kalanchoe pinnata, Pennicetum purpureum, Plantago palmata, Commelina difusa , Physalis angulata , Aloe barbadensis, Rumex bequaertii, Cannabis sativa, Carapa grandiflora Myrianthus arborea and Acmella caulirhiza have a 100% fidelity. The most commonly used organs are leafy stems (3714 %) and pressing (66, 6 %) is the most cited preparation technique. Conclusion: These results illustrate the richness of these peoples and these plant resources deserve scientific interest in order to be properly valorized.
