Abstract： Gastrointestinal tumors are prone to bleeding. According to traditional Chinese medicine， the blood formed by the middle energizer，is chronically consumed because of chronic disease，and this results in poor spleen yang and failure to control the blood， which makes the blood not transmit along channels and generates the out- of- channels blood. The core pathogenesis of gastrointestinal tumor bleeding is spleen deficiency and failure to control the blood，and therefore，the Spleen- Reinforcing and Blood- Containing Method should be adopted. In the treatment， formulas like Huangtu Decoction which plays the role of stopping bleeding by reinforcing the spleen can achieve a good clinical effect.
