Corosolic Acid lowers blood sugar significantly

Researchers from the Department of Diabetes and Clinical Nutrition at Kyoto University gave 31 people either 10mg Corosolic Acid or inactive placebo a number of times, 5 minutes before an oral glucose tolerance test consisting of drinking 75-g of sugar in water in a cross-over design. The test subjects had diabetes, or impaired glucose tolerance, impaired fasting glucose, and 4 had normal sugar activity. The Corosolic Acid lowered blood glucose within 60 minutes and reached statistical significance by 90 minutes. The study is published in the August 2006 issue of the Irish medical journal Diabetes Research and Clinical Practice
