The curative action of the extract was studied by its injection to the infected animals for 7 days and its prophylactic action--by introducing it 24 hours and, repeatedly, 1 hour before infection. The study revealed the increase of such characteristics as survival rate, mean survival time, body weight dynamics, as well as decreased level of virus accumulation in the brain, liver and heart tissues of the animalsunder experiment.
