    Background The genus Pennisetum contains remarkable natural bioactive components, and its 140 species are widely distributed in tropical and subtropical countries, where they are frequently used for therapeutic purposes such as the treatment of dysentery, fever, diabetes, and abdominal pain by indigenous people. However, the available information for this genus has not been thoroughly researched in terms of their bioactive principles and extracts. Aim of the review The current review provides a profound perception, enhanced understanding, and comprehensive information on the traditional uses, phytochemical compounds, and biological activities of the genus Pennisetum, as well as toxicological perspectives. Furthermore, the significance of ethnopharmacological uses, application, and the beneficial potential of Pennisetum species for the management of a variety of diseases were thoroughly discussed. Materials and methods The significant data of Pennisetum species was obtained through a thorough review of scientific articles published in a variety of databases, including Elsevier, Wiley, Web of Science, Springer, PubMed, Taylor and Francis, and Google Scholar. Furthermore, PhD and MSc theses were used in compiling and evaluating data obtained. Results The ethnopharmacological applications of Pennisetum genus plants in various countries were established through detailed analysis of the aforementioned databases and thesis. So far, only a few species' chemical compositions and a total of 35 metabolites (excluding amino acids and fatty acid constituents) have been studied, including saponins, tannins, flavonoids, alkaloids, steroids, anthocyanin phenols, terpenoids, and others. The crude extracts were found to have antioxidant, antimicrobial, anti-cytotoxic, anti-hypertensive, and anti-inflammatory properties. Furthermore, the significance of ethnopharmacological applications, application, and the positive potential of Pennisetum species for the management of a variety of disorders was thoroughly examined. Conclusions Although there are significant gaps in comprehending the traditional applications in the current available data, Pennisetum spp. are known to be rich in flavonoids, phenols, fatty acids, and amino acids with favorable medicinal characteristics. However, more research into the chemical makeup of innovative plant-derived medications is still needed. Furthermore, high-quality preclinical studies using a unique strategy are needed to assess the efficacy, safety, and mechanism of these plants.
