This formula comes from Dong Xi-yuan's Qing dynasty Yi Ji Bao Jian (Precious Mirror of the Records of Medicine) published in 1777 CE.
Within this formula, Gou Qi Zi, Ju Hua, and Shu Di are the sovereign ingredients. Gou Qi Zi enriches kidney yin and nourishes liver blood, boost the essence and brightens the eyes. Ju Hua is sweet, bitter, and slightly cold. It dispels wind and clears heat, clear the liver and brightens the eyes. Shu Di enriches kidney yin, boosts the essence, and fills the marrow. Shan Zhu Yu assists in warming and enriching the kidneys and boosting the liver. Shan Yao enriches the kidneys and supplements the spleen. Ze Xie and Fu Ling help drain any exuberance of kidney fire by leading it into the yin (i.e., urinary) tract. Dan Pi drains liver fire. It also quickens the blood and transforms stasis.
