Anti-influenza virus activity of two extracts of the Blackcurrant from New Zealand and Poland


  • New Zealand blackcurrant extract showed anti-viral effects against all four strains of influenza virus (IFV) tested
  • Anthocyanins from NZ blackcurrant extract inhibit influenza virus adsorption to cells and virus release from infected cells
  • Blackcurrant had an anti-septic effect against multiple strains of IFV as a prevention against infection
  • New Zealand blackcurrant showed ‘definite’ potential for use as a disinfectant and antiseptic agent to prevent IFV infection
