For patient has obstructive jaundice, or hepatocellular jaundice situation, may appropriate application Yin gardenia yellow medicine. Yin gardenia yellow drug for patient’s jaundice subside have positive effect, but for jaundice patient, need to judge patient cause jaundice cause, is due to bile duct’s obstruction pressure, or is due to hepatocyte necrosis after and cause jaundice. If the liver function test shows that the total bilirubin and direct bilirubin are elevated, combined with the elevation of alkaline phosphatase and GGT, then it is considered that the patient has biliary obstruction or the possibility of jaundice caused by tumor compression. Further ultrasound of the upper abdomen and magnetic resonance imaging of the upper abdomen are needed to investigate the nature and location of the biliary obstruction. In addition, if the patient’s total bilirubin and indirect bilirubin are elevated, it is most likely that the patient has hepatocellular necrosis. In this case, the patient needs to actively search for the cause of hepatocellular necrosis, most commonly caused by viral hepatitis. The most common cause is viral hepatitis. In this case, the patient needs to further investigate hepatitis B DNA or hepatitis C RNA to see if the virus has replicated. If the virus is replicating, and there is a combination of alanine aminotransferase and aliquot aminotransferase elevation, then we need to actively consider the liver protection treatment, and active antiviral treatment at the same time.
