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.
