This formula uses a two-chief herb strategy to nourish yin and vent heat.
Bie Jia (salty, cold) directly enriches the yin and is able to
guide Qing Hao (bitter, cold) to directly vent heat. Together they
actively clear deficiency heat from the deepest yin aspects of the
body. The five ingredients seek to nourish, clear, and vent and treat both root and branch of this pattern.
