Chai Hu Shu Gan San

柴胡疏肝散 Bupleurum Powder to Spread the Liver

Pure qi moving for a stuck Liver when pain is the main complaint. Tightness and pain under the ribs or across the chest, belching, sighing, a bloated stomach, and a short temper, in a person who is not tired or pale. Where Xiao Yao San supports and soothes, this one simply opens.

Seven herbs that all move in the same direction. No tonic, no moistener. It is a crowbar for a jammed door, which is why it works fast and should not be used for long.
