Abstract
The present invention relates to an antiviral composition containing an Aleurites fordii or Daphne kiusiana extract or a fraction thereof as an active ingredient. In detail, extracts of Aleurites fordii or Daphne kiusiana or fractions thereof can induce the secretion of an immune-related cytokine, interferon-γ (IFN-γ) in natural killer (NK) cells, and thus exhibit potent antiviral activity and superior effects for viral diseases, and therefore can be effectively used in an antiviral composition.
