Purpose: The purpose of this study is to report the effect of traditional Korean medical treatment on hypertension. Methods: In this study, we reviewed the medical records of 22 hypertension patients who visited a traditional Korean medical clinic at least twice a week for a week from 21th May 2012 to 14th July 2012. We investigated the changes of blood pressure in every week and the quality of life in 4 weeks. Results: All patients got acupuncture, herbal treatment, moxibustion. We divided 22 subjects into two groups to analyze; one groupwas the patientswho started treatment during the study(A, n=13), and the other group was the patients who enrolled this study on the course of treatment(B, n=9). In A group, we found the decrease trend of systolic blood pressure. It decreased in 11 out of 13 patients in the first observation week, 8 out of 10 in the second week, 3 out of 6 in the third week. 3 patients of B group maintained normal blood pressure (Systolic/Diastolic blood pressure<140/90 mmHg) during observation period without anti-hypertensive drugs. Patients who finished to check the quality of life(EQ5D) were 10. Quality of life was improved in 5 out of 10 patients. Conclusion: The effect of traditional Korean medical treatment on hypertension was unclear because the subjects were small in number. However we could observe some blood pressure improved cases. Further clinical study like well-designed randomized controlled trial should be conducted to determine the effect of the treatment. Contact: Young Eun Kim, jade2010@kiom.re.kr
