Bilirubin is extracted from bile of animals. It is very effective on relieving convulsion , allaying a fever , detoxifcation , decreasing blood pressure and promoting number of eosinophils in the blood . It is the basis of calculus bovis ariifactus and it also be used to make cosmetics , medicine , health products etc . Our bilirubin has past thin layer chromatography and liquid chromatography test by hubei entry & exit inspection and quarantine bureau technology centre . We can produce 40~50kg bilirubin every month , its purity is 95% -99%, and the structural stability is well, the purity doesn't reduce in more than one year .
