To observe the effect of Yiqi Congming Decoction（益气聪明汤）combined with acupuncture on dizziness caused by deficiency of Qi and blood.

A total of 100 cases of vertigo with deficiency of Qi and blood in the hospital from January 2020 to January 2023 were selected as research objects. By simple random number table，they were divided into observation group and control group with 50 cases in each group. Both groups received acupuncture treatment for 4 weeks，and the observation group was treated with Yiqi Congming Decoction for 4 weeks. Maximum vertebrobasilar blood systolic flow velocity，the levels of serum total cholesterol（TC）and fibrinogen（Fib）of the two groups were compared before and after treatment，and the vertigo scores of the two groups were compared before and after treatment. At the end of treatment，the therapeutic efficacy of the two groups and the occurrence of adverse reactions during treatment were compared according to the relevant standards of the Guiding Principles for Clinical Research of New Chinese Medicine Drugs.

The clinical recovery rates of the observation group and the control group were 38.00%（19/50）and 18.00%（9/50），respectively，and the difference was statistically significant（P<0.05）. After treatment，the levels of serum TC and Fib in the two groups were lower than those before treatment，and the levels of the observation group were lower than those of the control group. The difference was statistically significant（P<0.05）. After treatment，the maximum systolic flow velocities of left vertebral artery，right vertebral artery and basilar artery in both groups were significantly higher than those before treatment，and the values in the observation group were significantly higher than those of the control group. The difference was statistically significant（P<0.05）. After treatment，the vertigo score in both groups was higher than that before treatment，and the score of the observation group was significantly higher than that of the control group. The difference was statistically significant（P<0.05）. No adverse reactions occurred in both groups during treatment.

Yiqi Congming Decoction combined with acupuncture in the treatment of vertigo with deficiency of Qi and blood has better effect than acupuncture alone. It can significantly improve the maximum systolic flow velocity of vertebra-basilar artery in patients and has high safety，which is suitable for promotion.
