Abstract

Objectives: The present study was examined the effects of dietary supplement containing Kurozu concentrate on Blood Pressure, QOL and Traditional Chinese Medicine (TCM) Constitution. Methods: Forty subjects with slightly high blood pressure were assigned randomly to 2 groups (active group and placebo group). Kurozu-containing foods or the placebo was administered to the subjects daily for 12 weeks. At week 0, 6 and 12, blood samples were collected, physical measurements were taken, and the quality of life (SF-36v2) and TCM constitution were examined. Results: Significant differences on blood pressure and TCM constitution between the groups were observed at week 12. The change of QOL between the groups was observed significantly at week 6. Conclusion: These findings suggest that foods containing Kurozu have hypotensive action and improve effects on constitutional problems. In addition, it was confirmed that foods containing Kurozu are safe to ingest.
