Anti-inflammatory and Antioxidant Agents from Salvia Genus (Lamiaceae): An Assessment of the Current State of Knowledge

Background: Salvia species are known for their biological properties in many countries and might potentially provide novel therapeutic agents. This review provides an overview of the available literature on the anti-inflammatory and antioxidant effects of Salvia species. Methods: Using bibliographic databases, particularly PubMed, this review aims to add new information to the list of Salvia species, including S. ceratophylla, S. chloroleuca, S. fruticosa, S. lachostachys, S. lavandulifolia, S. miltiorrhiza, S. mirzayanii, S. officinalis, S. plebeia, S. verbenaca, and S. virgata, and their main constituents as promising antiinflammatory and antioxidant agents, highlighting their mode of action. Results: Salvia species are sources of health-promoting phytochemicals that comprise polyphenols, flavonoids, terpenes and several other constituents. Many studies have indicated that plants from the Salvia genus reduce the oxidative stress and may be able to prevent and/or to treat inflammatory diseases. These potential beneficial effects have been attributed to the presence of compounds that show antioxidant properties and that demonstrated to inhibit the molecular targets of pro-inflammatory mediators in inflammatory responses. Conclusion: Salvia species and their secondary metabolites may be potential agents to improve the quality of life in patients with inflammatory diseases.
