Black elderberries show antiviral activity.
Antibacterial activity of the extract was demonstrated in liquid-cultured strains of pathogenic bacteria often found in association with upper respiratory tract infections. Depending on the concentration, the extract inhibited their growth by 70% to more than 99%.
Studies on the antiviral activity of the extract were conducted and results showed that a low concentration of extract that would be safe to normal cells significantly inhibited the growth of a highly contagious avian type A influenza virus and slower mutating type B influenza virus. Further tests showed cells pre-exposed to the extract had diminished levels of virus production of about 30% and 25% for type A and B influenza virus, respectively. These results suggest that the extract inhibits cell factors, which allow the viruses to propagate. For further information: www.artemis-international.com
