Zhi Bai Di Huang Wan, Tabs

This formula comes from Qin Jing-ming's Qing dynasty Zheng Yin Mai Zhi(Patterns, causes, Pulses & Treatments)published in 1702 CE. Within this formula, Shu Di is the sovereign ingredient. It 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 lead yang down into the yin tract (i.e., into the urinary tract), thus leading ministerial fire back down to its lower source. Dan Pi drains liver fire and cools the blood. In addition, it quickens the blood and transforms stasis. Zhi Mu supplements yin and drains fire, while Huang Bai clears heat and eliminates dampness. Some Chinese authors also say that the combination of these two medicinals also leads ministerial fire back down to its lower source.
