NCT01699074

Brief Summary

The study is a Phase-I like double blind randomized placebo controlled crossover design trial. The objective is to assess the dose response relationship on glycemic and vascular effects of an acutely administered Korean White Ginseng (KWG)(Panax C.A. Meyer) in individuals with metabolic syndrome or type 2 diabetes . Twenty seven subjects with Type 2 Diabetes (Key inclusion criteria: HbA1c ≤8.5%)or metabolic syndrome (Key inclusion criteria: as defined by The US National Cholesterol Education Program Adult Treatment Panel III)will be recruited for the study.
