A comparative study on the antipyretic effect and underlying mechanisms of different bile-fermented Arisaemas

Cattle bile Arisaema (CBA) and Pig bile Arisaema (PBA) are both processed products fermented from Arisaema erubescens (Wall.) Schott and animal bile, which are recorded in China Pharmacopoeia. Traditionally, bile Arisaema was often used for clearing heat and eliminating phlegm, calming wind and calming panic. Modern pharmacological researches suggest that both two drugs exert an antipyretic effect, while there is lack of the systematical and comparative evidence on underlying mechanism.
