According to qi-blood theory

colorectal cancer is a chronic disease with intermingled deficiency and excess

based on the disharmony of qi and blood and with qi stagnation

blood stasis

and water dampness as important pathological factors. The treatment needs both reinforcement and elimination. Therefore

for patients with disharmony of qi and blood

the treatment should be tonifying deficiency

and for patients with qi stagnation

blood stasis

and water dampness

they should be treated with eliminating pathogen. Specifically

patients with deficiency of qi and blood

stagnation of qi

blood stasis

and water dampness should be treated with tonifying qi and blood

promoting qi circulation to remove stagnation

dispersing stasis and resolving masses and eliminating dampness and absorbing clots.The representative prescriptions were Bazhen Decoction（ 八珍汤）

Sini Powder（ 四逆散） and Houpo Sanwu Decoction（ 厚朴三物汤）

Dahuang Mudan Decoction（ 大黄牡丹汤） and Wenjing Decoction（ 温经汤）

and modified Yiyi Fuzi Baijiang Powder（ 薏苡附子败酱散）. Combined with the theory of strengthening healthy qi and eliminating pathogens

the combination of disease differentiation and syndrome differentiation

and the specificity of carcinogenesis caused by cancer toxin

the compatibility of anti-tumor Chinese medicine was used to enhance the anti-cancer effect

and improve the clinical curative effect of TCM treatment of colorectal cancer.
