Abstract: Objective　 To study the clinical effect of bloodletting at ear apex combined with foot bath with Chinese medicine for elderly patients with mild hypertension.Methods　 We enrolled 180 elderly patients with mild hypertension（stage 1 hypertension） who received free medical consultation in Chengnan Clinic，Foshan Chancheng Central Hospital from August 2015 to November 2016 and using a random number table，equally divided them into group A treated by bloodletting at ear apex，group B treated by foot bath with Chinese medicine，and group C treated by bloodletting at ear apex combined with foot bath with Chinese medicine.All of them were treated for 4 weeks（a course of treatment）．Comparisons were made between the groups in terms of the clinical response and systolic blood pressure（SBP） and diastolic blood pressure（DBP） measured at both baseline and the end of treatment.Results　After treatment，the clinical response in the groups was significantly different（P<0.05）；group C achieved better clinical response compared with group B（P<0.05）．SBP and DBP levels at baseline were similar in all groups（P>0.05），but after treatment，the two parameters differed significantly（P<0.05），both of them were lower in group C compared with other two groups（P<0.05），and DBP level was lower in group A compared with group B（P<0.05）．Both SBP and DBP levels decreased substantially in all groups after treatment（P<0.05）．Conclusion　The combination therapy was better than each of its components alone in improving the blood pressure.
