Abstract
Several studies have demonstrated a link between blood viscosity and various forms of liver dysfunction. Therefore, we investigated the effect of liver protective herbal materials, Sesamin combined with extract of Schisandra chinensis berry (Schisandra) for its potential to improve blood fluidity in humans. Ten human subjects were recruited to study the effect of sesamin combined with schisandra extract (SCH) for two weeks on blood viscosity. Blood fluidity was measured as the transit time for 100mul of heparinized whole blood to pass through a micro-channel array setup at baseline, 1 week and 2 weeks. For safety assessment, blood biochemistry, hematology and urine analysis were taken at baseline, 1 week and 2 weeks after SCH administration. No safety concern and adverse effects were observed during the 2-week continuous intake period. Intake of SCH reduced blood passage time by 9.0% and 9.7% at 1 and 2 weeks, respectively. In conclusion, this pilot clinical study indicates that the combined administration of sesamin with schisandra extract could improve blood fluidity after 1 week of oral intake and this effect was sustained up to 2 weeks.
