Detailed Description:
The antiviral agent, oseltamivir, is recommended by the World Health Organization (WHO) to treat recent outbreak novel influenza A (H1N1) virus infection around world. But limited stock and resistant strain emergence raised increasing concerns. Chinese medicinal herbs, are derived from plants and usually incorporate one or more herbs as the basic drug(s) to treat the disease. The investigators performed RCT to indicate that a combination treatment of Chinese medicinal herbs and oseltamivir is more effective than single oseltamivir in treating novel influenza A (H1N1) pneumonia.
