Detailed Description:

The purpose of this study is to evaluate an acute effect of Plantago asiatica L. extract consumption on antioxidative biomarkers in subjects with mild hyperlipidemia. Subjects will intake Plantago asiatica L. extract with a high fat meal for oxidative stress loading. Antioxidative biomarkers will be measured after single-dose administration of Plantago asiatica L. extract.
