Herbal immune boost? small study tests angelica root against placebo
NCT ID NCT03630328
First seen Jan 14, 2026 · Last updated May 16, 2026 · Updated 13 times
Summary
This study tested whether a dietary supplement made from Korean Angelica root (Cogni.Q) can increase certain immune cells. Fifteen healthy adults took either the supplement or a dummy pill (placebo) to see if the supplement raised levels of neutrophils (which fight bacteria) and natural killer cells (which fight viruses and cancer). The goal was to confirm that earlier immune-boosting effects were truly from the supplement, not chance.
