From: Anti-viral properties and mode of action of standardized Echinacea purpurea extract against highly pathogenic avian Influenza virus (H5N1, H7N7) and swine-origin H1N1 (S-OIV)

Figure 3

Pre-treatment of IV with EF is most effective. H5N1 HPAIV (MOI = 1) and MDCK cells were treated with EF (50 μg/ml) as indicated. Infected cells were then incubated in medium with or without EF for 8 and 24 hours and the infectious titer was determined (FFU/ml). The experiment was performed in triplicate, and titrations in duplicate.
