Background: Plants have been traditionally used for centuries to treat wounds and, over time, have been tested for their healing properties. There is a constant search for new natural resources that could be used to develop various topical wound care products. Methods: A comprehensive search of the literature was conducted in PubMed/MEDLINE, Scopus, and Web of Science databases (2022-2026) in accordance with the PRISMA 2020 guidelines. Included studies focused on current in vitro and in vivo research on hydrogels containing plant extracts from the Asteraceae and Lamiaceae families and their potential application in wound healing and skin regeneration. Results: An analysis of 24 included studies confirms that both families include interesting and valuable plants with antioxidant, antimicrobial and anti-inflammatory properties; these plants also influence collagen deposition, fibroblast proliferation, and epithelialization, and reduce the risk of infection, thereby contributing to faster wound healing. The most frequently tested phytoextract in this respect was Calendula officinalis (Asteraceae) incorporated into a hydrogel. A variety of materials, including natural, semi-synthetic, and synthetic polymers, as well as hybrid matrix, but also diverse formulation strategies, from simple solutions to more advanced and modern methods, have been used to produce hydrogels. Conclusions: This systematic review summarizes the current evidence, highlights directions and possibilities for the use of phytoextract-based hydrogels, and discusses limitations and future perspectives in the development of effective externally applied formulations to support wound healing.
