The hospitals' records of using the drug during the epidemic have been recognized by the World Health Organization.

　　The Chinese medicine has shown effectiveness in treating flu symptoms including fever, nasal congestion, cough and muscle soreness in clinical tests.

　　As one of the top-selling anti-influenza drugs in China, the capsule is available in 120,00 pharmacies around China and is also available in Hungary, Canada and Indonesia.

　　The company based in Shijiazhuang, capital of north China's Hebei Province, said getting an FDA certificate would further enhance the herbal medicine's standing in the international market.
