Efficacy and Safety of Chunghyul-dan (Qingwie-dan) in Patients with Hypercholesterolemia

Chunghyul-dan has inhibitory effects on HMG-CoA reductase and pancreatic lipase. We investigated whether Chunghyul-dan has therapeutic effects on humans with hypercholesterolemia. This study was a case-control, open-labeled clinical study. Subjects were treated with Chunghyul-dan (600 mg/day) or Atorvastatin (10 mg/day) for 8 weeks. Serum lipids were checked at baseline after 4 and 8 weeks of medication. While, Chunghyul-dan showed significant lipid-lowering effects, it was less effective than Atorvastatin. In comparison with the histological controls, Chunghyul-dan's effects were superior to placebo. On safety assessment, there was no adverse effect with the use of Chunghyul-dan in hepatic or renal toxicity. In conclusion, we suggest that Chunghyul-dan is a useful herbal medicine for hypercholesterolemia.
