To investigate the curative effect of regulating Du meridian and harmonizing stomach acupuncture combined with warm needle moxibustion at Zusanli（ST36）in the treatment of wind-cold type of peripheral facial paralysis and its influence on H-B grading.

A total of 132 patients with wind-cold type of peripheral facial paralysis admitted to the hospital from July 2020 to October 2022 were randomly divided into two groups with 66 cases in each group.

After treatment，H-B grading，FDIPscore，FDISscore and Portmann score were significantly improved in two groups（P<0.05），and the improvement was more significant in the observation group（P<0.05）. The scores of incomplete eyelid closure，frontal striae disappearance，mouth angle skew and shallow nasolabial groove were significantly decreased in two groups（P<0.05），and were more significantly decreased in the observation group（P<0.05）. In the control group，there were 2 cases of headache and nausea，1 case of drowsiness，1 case of local congestion and swelling，and 1 case of acupuncture dizziness. The total incidence of adverse reactions was 7.58%（5/66）. In the treatment group，headache and nausea in 1 case，drowsiness in 2 cases，local congestion and swelling in 2 cases，and acupuncture dizziness in 1 case. The total incidence of adverse reactions was 9.09%（6/66）. There was no significant difference between the two groups（P>0.05）.
