White peony is less cold but bitter, so it can clear liver heat or heat in the blood, but its function is weaker than that of red peony. One difference is its sour taste, which results in an astringent property. Cold and sourness may generate and stabilize the yin. As it enters the liver meridian, it particularly nourishes the liver yin and blood. It is an appropriate herb when there is yin deficiency with slight empty heat in the blood. In this situation, the main symptoms are dizziness, dry and burning eyes, irritability, and hypochondriac pain and distention.
