A Chinese herb known as y? zh? c?o (Commelina communis) was recently shown to reduce the H1N1 death rate by more than 50% in mice when administered after infection. If the herb was taken prophylactically (for prevention), the H1N1 virus was inhibited by up to 90%. Thus, ya zhi cao is yet another Chinese herb we can add to the arsenal against H1N1.
