Abstract: Objective To explore and analysis the clinical effect of Huazhuo Xingxue Tang on the recovery stage of cerebral infarction of phlegm stasis obstruction type. Methods A total of 98 patients with phlegm stasis obstruction type cerebral infarction during the recovery period diagnosed and treated at Hedong District Traditional Chinese Medicine Hospital in Tianjin from August 2020 to February 2023 were selected as the research subjects. Accorded to a 1:1 random number table method, the 98 patients were divided into the traditional Chinese medicine group of 49 cases and the control group of 49 cases. The control group were treated with conventional Western medicine, while the traditional Chinese medicine group were treated with Huazhuo Xingxue Tang on the basis of the control group. Both groups were treated and observed for 2 months, and the scores of nerve function deficit, mental state and cognitive function, changes in middle cerebral artery blood flow velocity and quality of life were compared between the two groups before and after treatment. Results After 2 months of treatment, the neurological deficit scores of both groups of patients decreased compared to before treatment, and the degree of downregulation in the traditional Chinese medicine group was greater. Compared with the control group, the difference was statistically significant (P<0.05); After 2 months of treatment, the mental state and cognitive function scores of the two groups of patients increased compared to before treatment, and the degree of increase was greater in the traditional Chinese medicine group. Compared with the control group, the difference was statistically significant (P<0.05); The end diastolic blood flow velocity and peak systolic blood flow velocity of the middle cerebral artery in the two groups of patients treated increased compared to before treatment, and the degree of increase in the traditional Chinese medicine group was greater. Compared with the control group, the difference was statistically significant (P<0.05); The quality of life scores of the traditional Chinese medicine group after two months of treatment showed a significant increase compared to the control group, and the difference was statistically significant (P<0.05). Conclusion Huazhuo Xingxue Tang can improve patients' neurological deficits, improve their mental state and cognitive function scores, improve the blood flow velocity of the middle cerebral artery, and thus improve their quality of life in the recovery period of phlegm stasis obstruction type cerebral infarction.
