Ancient herb put to the test: can angelica root supercharge immunity?
NCT ID NCT03630328
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a dietary supplement made from Korean Angelica root (Cogni.Q) can increase the number of key immune cells in the blood. Fifteen healthy adults took either the supplement or a placebo to see if the herb truly boosts neutrophils (which fight bacteria) and natural killer cells (which fight viruses and cancer). The goal was to confirm earlier findings that a single dose could raise these cell counts within 24 hours.
