.Influenza viruses cause respiratory diseases in humans and animals with high morbidity and mortality rates. Conventional anti-influenza drugs are reported to exert side-effects and newly emerging viral strains tend to develop resistance to these commonly used agents. Fritillaria thunbergii

The major biological active ingredients of Bulbus Fritillariae cirrhosae (BFC) are steroidal alkaloids, such as peimisine, imperialine-3β-D-glucoside, and peimine. The bulbus of Fritillaria unibracteata var. wabuensis (FUW) was officially recorded in the National Pharmacopoeia of China (2010

Seasonal and pandemic influenza infections are serious threats to public health and the global economy. Since antigenic drift reduces the effectiveness of conventional therapies against the virus, herbal medicine has been proposed as an alternative. Fritillaria thunbergii (FT) have been

BACKGROUND Traditional Chinese medicine (TCM) herbal formulae provide valuable therapeutic strategies. However, the active ingredients and mechanisms of action remain unclear for most of these formulae. Therefore, the identification of complex mechanisms is a major challenge in TCM
