In order to study on the theory of " phlegm and blood stasis having same source" and effects of drugs for resolving phlegm on blood rheology

effects of Ban Xia

Gua Lou

Zhe Bei Mu and Shi Chang Pu on whole blood viscosity

erythrocyte deformation index and plasma fibrinogen content in normal rats. Results indicated that the drugs.for resolving phlegm had functions of decreasing whole blood viscosity

inhibiting hemoagglutination （except Gua Lou） and increasing capability of erythrocyte deformation; at high shearing rate

Shi Chang Pu and Zhe Bei Mu could slightly increase whole blood viscosity: Shi Chang Pu increased slightly plasma fibrinogen content. It is suggested that resolving phlegm also can removing blood stasis

and the mechanism of the drug for resolving phlegm in decreasing blood viscosity is related with decrease of blood lipids and anti - peroxidation of lipids.
