Brazil, one of the most megadiverse countries, is home to numerous non-conventional edible plants (NCEP), whose functional applications are underexplored. This review highlighted the antimicrobial and antioxidant properties of Schinus terebinthifolius Raddi (pink pepper), Pereskia aculeata Miller (ora-pro-nóbis), and Tropaeolum majus L. (nasturtium). A literature review was conducted to identify key findings, bioactive compounds, extraction methods, gaps and challenges that affect the consistency of the results. The literature review covered studies published between 2012 and 2025, identified through keyword searches in scientific databases. Studies focusing on essential oils, undergraduate theses, dissertations, doctoral theses, and conference abstracts were excluded. After applying these criteria, a total of 45 studies were included in the final analysis. While antioxidant activity is consistently supported across various assays, antimicrobial evidence for P. aculeata and T. majus is often limited or inconclusive, despite frequent citations in the literature. There is a clear need to detailed compound profiling to establish correlations between biological activity and the specific metabolites responsible for such effects. Despite limitations, promising results support the potential of these plants for future applications in the food and pharmaceutical industries. By consolidating current findings and highlighting research limitations, this review provides a valuable resource to support and guide future investigations into the functional applications and bioactive constituents of NCEP.
