Description
Yin Chen Hao Tang (Artemisia Decoction) is the classical formula for Yang jaundice — bright yellow jaundice from damp-heat. By draining heat and damp through the urine and stool, it addresses the accumulation of damp-heat in the Liver and Gallbladder channels that causes jaundice. It is the foundation of modern TCM hepatology and one of the most studied formulas for hepatobiliary conditions.
