Retrospective study was made on the correlation between the intensity of blood - activation stasis -removal drugs in Yiqi Shengxue Recipe and the metastasis of qi - blood deficiency type of stomach carcinoma

with a positive result

demonstrating that the rat’s of its metastasis increased with the intensity of the drugs. It is suggested that this might be due to the decrease of platelet count and its aggregation

low plama fibrinogen . and increase of fibrinolysis in these patients. Moreover

medern pharmacology shows that most drug and recipes of blood - activation stasis -removal inhibit the platelet aggregation

blood coagulation

and increase fibrinolysis. It is suggested that

in such patients

when the pletelet count and their aggregation are markedly decreased

prolonged blood coagulation time with high FDP. the intensity of the drugs should be lowered so as to avoid metastasis.
