Liquorice and Immunity Boosting Properties
Glycyrrhizin (GA) and primary metabolite 18beta-glycyrrhetinic acid (GRA) are pharmacologically active components of the medicinal liquorice root. Both these components have previously been shown to have antiviral and immuno-modulatory properties.
These properties are well established, however the mechanisms of action are not completely understood.
In this study by Hardy et al, GA and GRA were tested for their ability to inhibit rotavirus replication in cell culture. The long term goal of this is to discover natural compounds that may complement existing vaccines.
Results & Conclusions:
GRA treatment reduced rotavirus yields by 99% when added to infected cultures
