To observe the impact of Buyang Huanwu Tang on cell immunity and immune complex clearance in order to confirm its effect on immunological functions. Methods:The model of qi deficiency and blood stagnancy was established on mice. The treatment group received Buyang Huanwu Tang, and was controlled by a normal group and a model group. We determined the content of circulating immune complex (CIC), calculated E-rosette forming rates, and phagocytic rates. Results:Of the abovementioned parameters, the treatment group was significantly different with the model group (P<0.05), and statistically the same with the normal group (P>0.05). Conclusion: Buyang Huanwu Tang can stimulate erythrocyte receptor activity and phagocytic function, and reduce CIC content.
