| Summary: | Abstract Background Studies have indicated that Plantago major L. (P. major) has therapeutic properties, such as anti-inflammatory, antioxidant, antifungal, immunostimulatory, and tissue regeneration. This plant species is assumed to provide potent tissue repair and healing in treatments of skin wound injuries, but the understanding of its effectiveness is still unclear. The systematic review proposed herein aims to assess effectiveness of P. major for wound healing in animal models. Methods We will conduct database searches in BVS, PubMed, Scopus, Web of Science, CINAHL, and CABDirect. Reviewers will independently evaluate titles, abstracts, and full-text articles retrieved from databases to identify potentially eligible studies. Relevant articles will be assessed for risk of bias and quality. The database searches will include analysis of wound healing rate through macroscopic evaluation, photo images, or calculation of the wound area retraction until the wound closure. Relevant data will be compiled for the capability and effectiveness of P. major treatments in accelerating wound healing. Random effects meta-analysis models will be employed to compare among groups based on outcome variables from studies reporting sufficient high-quality data. Discussion Results of this systematic review will be presented in a narrative synthesis form. They will provide a summary and clear understanding of the relevant current questions and evidences directly related to P. major effective tissue repair and healing. Outcomes of this systematic review will contribute with important information that could benefit future research efforts and potential applicability in humans.
