Can Antiviral Activity of Licorice Help Fight COVID-19 Infection?

The phytotherapeutic properties of Glycyrrhiza glabra (licorice) extract are mainly attributed to glycyrrhizin (GR) and glycyrrhetinic acid (GA). Among their possible pharmacological actions, the ability to act against viruses belonging to different families, including SARS coronavirus, is particularly important. With the COVID-19 emergency and the urgent need for compounds to counteract the pandemic, the antiviral properties of GR and GA, as pure substances or as components of licorice extract, attracted attention in the last year and supported the launch of two clinical trials. In silico docking studies reported that GR and GA may directly interact with the key players in viral internalization and replication such as angiotensin-converting enzyme 2 (ACE2), spike protein, the host transmembrane serine protease 2, and 3-chymotrypsin-like cysteine protease. In vitro data indicated that GR can interfere with virus entry by directly interacting with ACE2 and spike, with a nonspecific effect on cell and viral membranes. Additional anti-inflammatory and antioxidant effects of GR cannot be excluded. These multiple activities of GR and licorice extract are critically re-assessed in this review, and their possible role against the spread of the SARS-CoV-2 and the features of COVID-19 disease is discussed.

The current CoViD-19 pandemic threatens both physical and psychological well-being. According to the bio-psycho-social model, Units of Clinical Psychology of the Hospitals in Lombardy (Italy) reacted to this risk, offering diversified interventions, described in the present contribution. The medical staff operated on the front line during the emergency: psychologists addressed their needs through individual clinical work, sessions of decompression and debriefing. At the same time, Units of Clinical Psychology supported the hospitalized positive patients by conducting psychological consultations, either on the ward or through devices. Moreover, some hospitals activated helplines to address the needs of the population and family members, who were particularly vulnerable during the relative's illness and after the mourning.
