Body weights of mice infected with H1N1 virus and treated with FT extract and oseltamivir at different timepoints (4 h and 24 h). (A) Mice (n = 10 per group) were intranasally infected with 20MLD₅₀ of H1N1 virus strain. FT extracts (6 mg/mouse) or oseltamivir (200 μg/mouse) were administered orally to mice by gavage 4 h after virus infection and treatment continued twice daily from days 1 to 10 post-infection. (B) Infected mice were treated with FT extracts or oseltamivir 24 h after virus infection and administration continued twice daily from days 1 to 10 post-infection.
