Potential Therapeutic and Medicinal Applications of Four Invasive Non-Native Plant Species: A PRISMA-Guided...

Invasive non-native plant species are of ecological concern globally, as they may negatively affect biodiversity, the economy, and human health. At the same time, invasive non-native plants comprise an underutilised biomass that contains valuable natural bioactive compounds, which could find various biomedical applications and potential medicinal uses. In this paper, we aimed to systematically review the published data surrounding four selected invasive non-native plant species in a medical and therapeutic context. The search was conducted using PubMed and PRISMA guidelines, and strict criteria were employed to provide a thorough framework for the study selection process. After rigorous screening of the 53 selected articles, we were able to summarise the main findings and current knowledge regarding the valorisation opportunities for the selected plants in a medical context and to identify research gaps and highlight further research opportunities. Finally, we concluded that the selected invasive non-native plant species may provide valuable services in the biomedical field if the focus of future research is concentrated on their potential applicability in clinical settings. Furthermore, the valorisation of invasive non-native plant species may prove to be a viable strategy for controlling their spread.
