Figure 5. Ginseng polysaccharide effects on influenza infection.

Mixtures of virus (A/California/2009, 3 LD₅₀) and different amounts of ginseng polysaccharide (2.5 mg/kg, 25 mg/kg) were used to infect mice intranasally (n = 6). The body weight changes (A) and survival rates (B) were monitored daily for 14 days. Mock: naïve mice infected with virus in PBS, GP 2.5 mg: naïve mice infected with a mixture of virus and 2.5 mg/kg of ginseng polysaccharide, GP 25 mg: naïve mice infected with a mixture of virus and 25 mg/kg of ginseng polysaccharide.
