The formula of Gui Fu Di Huang Wan is "based on the formula of Six-flavored Di Huang Wan plus cinnamon and epimedium". Because the Six-flavored Dihuang Pill nourishes the yin of the liver and kidneys, it is combined with cinnamon and fenzi to warm and tonify the yang in the kidneys to achieve the purpose of "benefiting the source of fire and eliminating the cataracts of the yin and the kidney". The combination of all the drugs, both tonic kidney yin, and tonic kidney yang, yin and yang, yin and yang, yin and yang, as Zhang Jingyue said, "good yang tonic, must be in the yin and seek yang, yang get yin to help and biochemistry infinite". Therefore, it is said that "Gui Su Di Huang Wan is the same complementary yin and yang".
