Brief Summary

This study was conducted to investigate the effects of daily supplementation of Angelica Gigas Nakai and Allium Cepa L.Extract Mixtures on the Improvement of Blood Flow.

Detailed Description

This study was a 12-week, randomized, double-blind, placebo-controlled human trial. 80 subjects were randomly divided into Angelica Gigas Nakai and Allium Cepa L.Extract Mixtures group and a placebo group. It is to evaluate the changes in the displayed evaluation items when taking Angelica Gigas Nakai and Allium Cepa L.Extract Mixtures once a day, in comparison with taking a placebo.
