Oregon Grape Root: What It Is and How to Use It
Oregon grape root is the dried root of Mahonia aquifolium, an evergreen shrub native to the Pacific Northwest — and despite the name, it is not related to grapes at all. The root is bright yellow inside, a sign of berberine, the bitter compound it is known for. Find it in the bulk herb section at William's Natural Foods, 12249 San Pablo Ave, Richmond, CA 94805.

Frequently Asked Questions
Why is it called Oregon grape if it is not a grape?
The shrub produces clusters of dusty-blue berries that look a bit like small grapes, which is where the common name comes from. Botanically, though, it is in the barberry family, not the grape family — and it is the root, not the berries, that herbalists traditionally use.
What does Oregon grape root taste like?
Intensely bitter. That bitterness comes from berberine and related alkaloids, the same family of compounds that gives goldenseal its bite. It is almost always brewed as a strong tea or tinctured rather than eaten straight.
What is Oregon grape root traditionally used for?
Pacific Northwest Indigenous peoples traditionally used the root for a variety of purposes, and it later entered Western herbal practice as a bitter tonic herb traditionally used to support digestion. Scientific evidence for specific effects is limited, so it is best approached as a traditional bitter herb.
How is it usually prepared?
The traditional preparation is a decoction — simmering the cut root in water rather than just steeping it — because roots need more heat and time than leaves to release their properties. It can also be tinctured. Because it is so bitter, many people blend it with milder herbs.
Did you know? The Oregon grape flower (Mahonia aquifolium) has been the state flower of Oregon since 1899 (source: Oregon state symbols). The same plant admired in gardens across the Pacific Northwest is the source of this traditional bitter root.
