Creeping Oregon Grape
Mahonia repens
Long before it had a Latin name, creeping Oregon grape was known to the peoples of the intermountain West as a bitter, golden-rooted helper for a sluggish stomach and a tired liver. Its root bark, startlingly yellow when cut, was simmered into decoctions for digestive complaints and used as a wash for skin troubles, much as its taller relative Mahonia aquifolium was used along the Pacific coast. Because it spreads low and thick across dry, rocky ground where little else thrives, it was also a plant people simply learned to recognize and reach for close to home. Later herbalists folded it into the same bitter-tonic tradition as barberry and goldenseal, prized for the same golden alkaloid at its core.

Traditional preparations.
A traditional bitter decoction, historically taken in small amounts before meals to encourage digestion.
Traditionally, 1 teaspoon of dried, chopped root bark is simmered gently in 250 ml of water for 10 to 15 minutes, then strained and allowed to cool slightly before drinking.
Safety.
Creeping Oregon grape contains berberine and should be avoided in pregnancy and breastfeeding and never given to infants, since it has been linked to a serious newborn jaundice-like condition. It can also interact with blood thinners, blood sugar or blood pressure medications, and liver-processed drugs, so use only small, traditional amounts.
