Angelica Gigas Dietary Supplements and Human Immune Cells

This human study will test the impact of dietary supplement vegicaps containing Korean Angelica root extract on 2 types of human immune cells: neutrophils that kill bacteria and other germs and natural killer (NK) cells that kill virus-infected cells and cancers. The investigators had done an earlier study with Korean Angelica supplement and discovered even a single dose of it increased blood neutrophils and NK cells within 24 h. In the new study, Korean Angelica capsules (Cogni.Q) will be compared head-to-head with dummy (placebo) capsules. This is to make sure the immune boosting actions are really from the Korean Angelica supplement.
