Can You Take Korean Danggi (Angelica) and Quercetin Together?

Use extra care with this pair

The short answer

Korean Danggi (Angelica) contains coumarins with anticoagulant properties, while Quercetin has antiplatelet or blood-thinning properties. Taking both may amplify blood-thinning effects through different mechanisms.

How to arrange timing

Both Korean Danggi (Angelica) and Quercetin may affect blood clotting through different pathways. Consider monitoring for signs of increased bleeding (easy bruising, prolonged cuts) when taking both supplements together.
