Wintergreen Barberry
Berberis julianae
Wintergreen barberry is, first and foremost, a garden workhorse: gardeners across the world have prized its dense, glossy, spine-edged foliage for hedging that nothing dares push through, and its cheerful yellow spring flowers give way to blue-black berries that carry it into autumn. Like its many barberry cousins, its inner bark and roots carry the bright yellow alkaloid berberine, and across cultures the genus Berberis has long been steeped as a bitter tonic to rouse a tired appetite and ease a heavy stomach. Wintergreen barberry itself is used less often in this way than its better documented relatives, European barberry and tree turmeric, so most of what is known about it traditionally speaks to its garden virtues rather than its medicine chest ones.

Traditional preparations.
A short-term bitter decoction traditionally used the way other berberine-rich barberries have long been used in folk herbalism, to stir a sluggish appetite and support digestion after a heavy meal.
Traditionally, a scant 1/2 teaspoon of dried bark is simmered gently in 1 cup of water for 10 to 15 minutes, then strained and sipped slowly. Used only occasionally and never as a daily habit.
Safety.
Berberine in the bark should not be used during pregnancy or breastfeeding and must never be given to infants, since it has been linked to a serious jaundice complication called kernicterus. It can also interact with blood thinners, blood sugar medication, and liver-processed drugs, and the plant's spines can cause painful puncture wounds.
