Barberry (Berberis vulgaris) is a bush native to Europe, North Africa that now grows wild in many regions of North America. The berries of the barberry are traditionally used to make jams and jellies. But the herb also has a long history as a folk remedy for digestive disorders, including constipation, diarrhea, dyspepsia, heartburn, and loss of appetite.
It was traditionally thought to increase the flow of bile, which is why it was used for liver and gallbladder problems. It was also used topically to treat skin conditions like eczema, psoriasis, acne, and minor wounds.
