To investigate the clinical effect of Jianpi Shugan Tongru Prescription（健脾疏肝通乳方）combined with low frequency pulse electrical stimulation in patients with postpartum lactation deficiency（syndrome of weakness of Qi and blood）.

A total of 96 patients with postpartum lactation deficiency（syndrome of weakness of Qi and blood）admitted from January 2022 to December 2023 were included in this grouping study. The grouping method was random number table method，and they were divided into control group and observation group according to different treatment methods. The patients in the control group（48 cases）were given low-frequency pulse electrical stimulation treatment. Those in the observation group（48 cases）were given low-frequency pulse electrical stimulation and Jianpi Shugan Tongru Prescription，and the data of patients in each group was compared，including the clinical efficacy，the changes in TCM symptom scores，the levels of estradiol（E2）and prolactin（PRL）before and after treatment，the changes in breast filling degree，lactation volume and milk quality score，breastfeeding status，treatment adverse reactions and treatment satisfaction rate.

Compared with those in the control group，the total effective rate and satisfaction rate were higher in the observation group（P<0.05）. The rate of exclusive breastfeeding in the observation group was higher than that in the control group（P<0.05）. There was 1 case of bitter mouth in the observation group and no adverse reaction in the control group（P>0.05）. The scores of TCM syndrome，the levels of E2 and PRL，breast filling degree，lactation volume and milk quality scores of both groups were not significant before treatment（P>0.05）. After treatment，all indexes of both groups were improved，and all indexes of the observation group were better than those of the control group（P<0.05）.

The combination treatment of Jianpi Shugan Tonglu Prescription and low-frequency pulse electrical stimulation for patients with postpartum lactation deficiency（syndrome of weakness of Qi and blood）has a more significant effect. After treatment，the symptoms of patients are improved. They can better secrete milk，improve the rate of exclusive breastfeeding，meet the needs of newborns and have fewer adverse reactions and higher safety，and the patients are more satisfied and recognized.
