Anti-virus effect of traditional Chinese medicine Yi-Fu-Qing granule on acute respiratory tract infections.
Yi-Fu-Qing granule is a traditional Chinese medicine for the treatment of acute respiratory tract infections. The present study sought to investigate the anti-virus effects of Yi-Fu-Qing granule on acute respiratory infections with respiratory syncytial virus (RSV) and human adenoviruses type 3 (Ad3). The cytotoxicity of Yi-Fu-Qing granule was evaluated by the neutral red assay on HeLa cells. The antiviral effect of Yi-Fu-Qing granule was tested by observing the cytopathogenic effect (CPE) with a compound mixture of Isatis leaf as the positive control drug. The results indicated that the highest non-toxicity concentration of Yi-Fu-Qing granule on Hela cells was 1:100. The CPE reduction assay showed that Yi-Fu-Qing granule inhibited RSV and Ad3 replication at a concentration of 1:100. Thus, Yi-Fu-Qing granule may have a significant antivirus effect on acute respiratory tract infections with RSV and Ad3 infections and this could prove useful for further antivirus research on acute respiratory tract infections.
