Oregon Grape Overview
Oregon grape (Mahonia aquifolium) is a perennial shrub that is native to the Pacific Northwest region of the United States, including Oregon and Washington. It is also found in parts of Canada. The plant is a member of the barberry family (Berberidaceae) and is closely related to the holly plant.
Oregon grape is often grown as an ornamental plant due to its attractive foliage and colorful berries. It is also used medicinally and is believed to have astringent, tonic, and anti-inflammatory properties. The root of the plant is used to make a herbal extract that is used to treat a variety of ailments, including skin conditions, digestive problems, and respiratory conditions. Most of the positive evidence for a medicinal effect is with topical applications as some research has shown topical preparations may modestly decrease the severity of psoriasis. It is important to note that the berries of the plant can be somewhat bitter and may contain toxins, so they should be eaten in moderation.
