    The plant species Schkuhria Pinnata, 'Canchalagua,' is traditionally used for its antioxidant and antimicrobial activities. The objective was to evaluate the efficacy of the antimicrobial and antioxidant activity of Schkuhria Pinnata, 'Canchalagua,' in inhibiting bacterial growth and reducing free radicals. A systematic intervention review study was conducted. Eligibility criteria were initially established, followed by a search in the Renati, Alicia (Concytec), Scielo, PubMed, Elsevier, Lilacs, Virtual Health Library (VHL), and Google Scholar databases. Studies were selected using the PRISMA method. A total of 103 articles were obtained, from which 11 studies were selected for data extraction and bias assessment, described by the Joanna Briggs Institute (2014). Metabolites were identified and quantified in different parts of the plant using precipitation, coloration, foaming, Folin-Ciocalteu, and aluminum chloride colorimetric methods. For the evaluation of antioxidant activity, the DPPH and ABTS methods were used, and the extracts showed reduction of free radicals. For antimicrobial activity, agar diffusion and dilution methods were employed. The extracts presented inhibition against Propionibacterium acnes, Pseudomonas aeruginosa, Escherichia coli, Enterococcus faecalis, Staphylococcus aureus, Mycobacterium smegmatis, Malephora lutea, and Staphylococcus epidermidis. Metabolites responsible for the antioxidant and antimicrobial activity were identified, and Schkuhria Pinnata, 'Canchalagua,' demonstrated efficacy in reducing free radicals and inhibiting bacteria.
