Korean Angelica (Angelica gigas) is a perennial from East Asia. Its roots have a long history in Korean and traditional Chinese medicine, mostly for women’s health and overall vitality. Human research is sparse. Early work looks at a compound called decursinol, but no clear benefit has been pinned down yet.
People usually take the powdered root, a standardized extract, or a tincture with meals. The plant contains coumarins that can slow blood clotting. Avoid it if you take a blood thinner such as warfarin. Due to missing safety data, pregnant and breastfeeding women should also steer clear.
