Can Renshen Jianpi Pills treat yin deficiency?

Ren Shen Jian Pi Wan generally cannot treat yin deficiency. Ren Shen Jian Pi Wan is warm and hot in nature, and is mainly used to treat conditions caused by spleen-stomach weakness and deficiency of qi and blood with cold symptoms. Yin deficiency with hyperactivity of fire results from internal deficiency heat; taking Ren Shen Jian Pi Wan may exacerbate the condition, so it is not recommended. For yin deficiency with fire hyperactivity, medications such as Zhi Bai Di Huang Wan or Liu Wei Di Huang Wan—which nourish the kidneys, enrich yin, and reduce internal heat—can be used for regulation.
