- Used S. nigra from Hungary
- The researchers extracted flavinoids from elderberries, and they bound to H1N1 virus (flu) and blocked infection in vitro (experiment done “in a dish”)
- They observed dose-dependent inhibition (higher concentration, greater inhibition of infection). Elderberry concentrations of 100, 250, 500, and 1000 µg/ml (micrograms per milliliter) were evaluated. 50% viral inhibition was observed at 250 µg/ml, and 100% inhibition was observed for 1000 µg/ml concentrations of elderberry.
- The anti-viral blocking action similar to that seen for Tamiflu
