Advanced prostate cancer is in the nature of root deficiency and branch excess， mainly manifested as spleen-kidney depletion and “dampness”， “toxin”， “stasis” congealing in the lower

jiao

（焦）， respectively. HUANG Yuanyu's theory of center

qi

can be summarized as “four earth axes， one

qi

circulates around”. The main content of this theory is “the rise of wood fire on the left road， the mediation of earth

qi

in the middle

jiao

， and the convergence of gold water on the right road”. If the circulation of

qi

in the spleen and stomach and the flow of four-dimensional

qi

movement is smooth， the circulation of

qi

throughout the body will be unblocked， and theclear and the turbid will be separated and restored.

Huangya Decoction

（黄芽汤） comes from

An Elucidation of Four Sages

（《四圣心源》）. It takes “loss of transportation due to kidney cold and earth dampness” as the key， and can promote the circulation of

qi

and dissipate “dampness”， “toxin”， “stasis” through warming

yang

and supplementing fire， banking up earth and draining water， providing a new idea for the clinical treatment of prostate cancer in traditional Chinese medicine.
