Objective To discuss the effect of modified Guizhi Fuling Tang（桂枝茯苓汤

GFT） combined with conventional treatment in senile essential hypertension with blood stasis syndrome. Methods Sixty-eight elderly essential hypertension patients with blood stasis syndrome were randomized into a treatment group and a control group

with 34 cases in each. Both groups were treated with conventional western medicine perindopril tablets and hydrochlorothiazide tablets. Additionally

the treatment group was added with oral modified GFT

one dose a day

for 12 weeks. Before and after treatment

Chinese medicine symptom scores were measured to determine the efficacy of improving Chinese medicine syndromes; ambulatory blood pressure were tested

including 24 h mean systolic blood pressure（24-SBP）

24 h mean diastolic blood pressure（24-DBP）

nighttime mean systolic blood pressure（N-SBP）

nighttime mean diastolic blood pressure（N-DBP）

daytime mean systolic blood pressure（D-SBP） and daytime mean diastolic pressure（D-DBP）

to calculate the pulse pressure; and hematocrit was calculated. Results After treatment in the treatment group

20 cases were markedly effective

12 cases effective

2 cases ineffective

and 0 cases aggravated. The total effective rate was 95. 59%. In the control group

17 cases were markedly effective

10 effective

6 ineffective and 1 case aggravated. The total effective rate was 79. 41%. Effect of improving Chinese medicine syndrome in the treatment group was better than that in the control group（P < 0. 05）. The 24-SBP

24-DBP

NSBP

D-SBP and D-DBP in the treatment group after treatment were significantly lower than those before treatment

and also significantly lower than those in the control group after treatment（P < 0. 05 or P < 0. 01）. The pulse pressure and hematocrit after treatment were lower than those before treatment in each group

and the decrease in the treatment group was more obvious than that in the control group（P < 0. 05）. Conclusion Modified GFT combined with conventional western medicine can reduce the pulse pressure and improve the hematocrit in elderly patients with essential hypertension with blood stasis syndrome

and its curative effect seems superior to that of conventional treatment alone.
