Moreover, shu di huang and shao yao, which are yin and soften in nature, combine with dang gui and chuan xiong, which are acrid in taste and warm in nature, to invigorate blood without stagnating the blood. It is the characteristic of this formula. Four herbs together have the function of nourishing and regulating blood, and regulating yin and blood.
