Colorectal cancer is one of the common malignant tumors of the digestive tract

with high incidence and mortality rate in China

and the trend of colorectal cancer becoming more prevalent among younger individuals is increasingly evident. Professor Jia Yingjie

laureate of the title "National Prestigious TCM Doctor"

put forward based on decades of clinical experience and existing theories a new idea on the pathogenesis of "cancer turbidity"

and created a new rule of "dethroning turbidity and banking up the foundation" to treat cancer. He believed that when cancer occurs

turbidity should be the primary cause

which is yin in nature and therefore tends to descend

leading to the fact that patterns involving the middle and lower

jiao

are most common. Dampness turbidity pouring downwards and the result ant accumulation of toxin and blood stasis are key to the disease. The treatment should follow the principle of "banking up the middle

jiao

and dethroning the lower

jiao

"

adhere to banking up the foundation

reinforce healthy qi by fortifying the spleen

regulating qi

and activating the middle

jiao

. Turbidity should be dethroned in multiple ways

so as to eliminate evil. Modified versions of ancient prescriptions can used and the treatment should be adjusted flexibly. This has been proved to be effective in clinical practice. Differentiation of diseases and syndromes complement each other

so do syndrome differentiation based on

organs and the three

jiao

. Under the guidance of holistic treatment and careful selection of herbs

desirable clinical result have been achieved

which is demonstrated in this article

evidenced by one case record.
