Oregon Grape Berries

Berberis aquifolium

Illustration: Oregon grape (Berberis aquifolium) berry clusters

Identification: Holly-like spiny evergreen leaflets; yellow flower clusters in spring; dusty blue-black berry clusters in summer. (The medicinal root entry is in the remedies chapters — this is the food use.)

Dangerous look-alikes: No toxic look-alike with holly-like evergreen leaves + blue-black clustered berries.

Edible parts: Ripe berries.

Season and habitat: Summer. Dry woods, rocky slopes.

Preparation: Eye-wateringly tart raw — best as jelly, syrup, or wine with plenty of sugar. High in berberine-adjacent compounds; eat as food, not medicine, in normal quantities.

Notes: Cross-reference: the root's psoriasis use is in the More Remedies chapter.
