Medicinal plants used for wound healing in Lubumbashi have yet to be discovered. Inventory or profile of their taxa has yet to be established. The present study was carried out to survey the plants used in traditional medicine in Lubumbashi to treat wounds and to define their ethnomedical characteristics. The study was conducted between March 2021 and August 2022, using semistructured interview surveys of households (n = 2730), herbalists (n = 48), and traditional practitioners: TPs (n = 128).The 2,906 interviewed (sex ratio M/F = 0.9; mean age: 56 ± 3 years; and experience: 17 ± 4 years) provided information on 166 taxa, 130 used against chronic wounds, among which Securidaca longepedunculata was the top cited. Most of these taxa are shrubs (33%), belonging to 48 botanical families dominated by the Fabaceae (16%). They are indicated in 70 other pathologies. From these 166 taxa, 198 healing recipes are obtained, 11 combining more than one plant. In all these recipes, the leaf (>36%) is the most used part, and the poultice (>36%) is the most popular form of use. Twelve taxa are cited for the first time as medicinal plants, of which Agelanthus zizyphifolius has the highest consensus and Erigeron sumatrensis has the highest usual value. For the various plants used to treat wounds, some of which are specific to the region, further studies should focus on validating this traditional use.

Wound healing is a complex process that can be improved through advanced biomedical approaches. Incorporating nanopolymers and plant extracts into wound dressings offers a favorable strategy for promoting tissue repair. Nanopolymers provide a controlled environment for sustained drug release while also protecting the wound from external contaminants. When combined with bioactive compounds from plant extracts, which possess antioxidant, anti-inflammatory, and antimicrobial properties, this hybrid approach can accelerate healing, reduce infection, and improve tissue regeneration. Hence, in this study, we have synthesized alginate/gelatin hydrogel blended with only nanosilver (Alg/gel-Ag) and with nanosilver and plant extracts like aloe vera, curcumin, plantain peel extract, and Calendula flower petal extract (Alg/gel-AgP). The synthesized hydrogels were characterized using different photophysical tools, and the cytotoxicity effect was studied using a fibroblast cell line (V79). The antibacterial effect of the hydrogels was also observed against E. coli and S. aureus, determining the MIC and MBC. The wound healing in vitro was also assessed using scratch assay which depicted a rapid wound closure for Alg/gel-AgP compared to the untreated control and Alg/gel-Ag. The combined effect between nanotechnology and natural extracts represents a novel and effective approach for enhancing the wound healing process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
