The Acacia (Vachellia nilotica (L.) P.J.H. Hurter & Mabb.): Traditional Uses and Recent Advances on Its...

For thousands of years, Vachellia nilotica has been widely used as an herbal medicine to treat some diseases and symptoms, including respiratory, gastrointestinal and urogenital ailments. The present study was adapted to document and assemble existing information about V. nilotica and its evidence-based ethnopharmacological activities, with brief reviews on the description, geographical distribution, ecology, medical uses and phytochemistry. A literature review and information up to 2024 was performed in various scientific databases, including PubMed, Science Direct and Google Scholar. The keywords were "Acacia nilotica", "Botany", "ecology", "Traditional uses", "Phytochemistry", "Polyphenols", "Molecular docking", "Ethnopharmacological activities" and "toxicity", among others. V. nilotica has a wide range of uses, with low toxicity, reported in different countries. It can be infused into oils or tea or incorporated into paste, poultice and biscuits, used as an emollient, antidiarrheal, astringent and as an antidote for bite poisons. Glucose and lipid-lowering, anti-inflammatory, analgesic, antipyretic, antioxidant, antihypertensive, antibacterial, antifungal, antiviral and anthelmintic activities are the most prominent. Over 150 chemical components have been identified from V. nilotica that could be associated with its potential actions. Quercetin, rutin, kaempferol, naringenin, catechin, epicatechin, gallic acid, ellagic acid, lupeol and niloticane are its main active constituents. From the research data, and despite the fact that human clinical trials and detailed methodological studies are scarce, V. nilotica has shown wide-ranging activities, though the most robust evidence is related to the treatment of microbial infections, diarrhea, wound and ulcer healing and for topical application. More pharmacological and toxicological studies are required to further elucidate the mechanisms of action, potential side effects, and optimal dosages for these treatments. Additionally, more clinical trials are needed to validate these traditional uses in human populations and to ensure the safety and efficacy of V. nilotica for these applications. This article offers an overview of therapeutic applications by utilizing traditional uses and recent findings on phytochemical studies, and clinical and pharmacological research.
