Antiviral activity of medicinal plant-derived products against SARS-CoV-2.

This review presents information from several studies that have demonstrated the antiviral activity of extracts (, , , , , , , , and ) and phytocompounds derived from medicinal plants (artemisinins, glycyrrhizin, and phenolic compounds) against SARS-CoV-2. A brief background of the plant products studied, the methodology used to evaluate the antiviral activity, the main findings from the research, and the possible mechanisms of action are presented. These plant products have been shown to impede the adsorption of SARS-CoV-2 to the host cell, and prevent multiplication of the virus post its entry into the host cell.
