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.

Preparation

Decoct Yin Chen Hao first for 20 minutes, then add Da Huang and Zhi Zi for final 10 minutes. Strain and take cool.

Dosage

Decoction: 1–2 doses/day for acute conditions. Take cool or at room temperature. Reduce frequency once jaundice improves.
