Formula Rationale

Spirityin (Liu Wei Di Huang Wan) consists of three tonic and three sedative herbs. Both sedative and tonifying actions are carried out simultaneously, with more emphasis on the tonifying action though.

Di Huang is the chief herb with its action in tonifying Kidney yin and jing (essence), and replenishes the marrow. Shan Zhu Yu nourishes the Liver and Kidney and condenses jing. Shan Yao tonifies the Spleen and Kidney and consolidates jing. Altogether these three herbs address the deficiencies in the Kidney, Liver, and Spleen.

Ze Xie calms the Kidney, descends the turbidity, and checks the stagnating effect of Di Huang. Mu Dan Pi sedates yin-deficiency fire of the Liver and balances the astringent property of Shan Zhu Yu. Fu Ling tonifies the Spleen to resolve dampness and harmonizes Shao Yao.
