The purpose of this study was to investigate how herb extracts may improve blood circulation. Twenty-six extracts from nine different herbs (marjoram, lavender, dill, rosemary, hyssop, rose, lemon balm, pineapple sage, and echinacea) were evaluated for their anti-hypertensive effects via angiotensin I converting enzyme (ACE) inhibition. Their cholesterol-lowering effects via hydroxy-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibition and their fibrinolytic activity via fibrin-plate method were also evaluated. Both water extraction of rose flowers and 70% EtOH extraction of pineapple sage leaves effectively reduced the ACE activity with inhibition rates of 133.8% and 91.2%, respectively. Similarly, both water and 70% EtOH extracts of rose flowers strongly inhibited the enzymatic activity of HMG-CoA reductase by 48.9% and 80.5%, respectively. Water and 70% EtOH extracts of rose flowers also showed relatively high fibrinolytic activity. Based on these observations, rose flower extracts can be developed as a functional tool for use in the improvement of blood circulation.
