Oregon Grape derives its name from its use as a medicine and food along the Oregon Trail. Traditional uses of these three components differ only slightly, and Oregon grape root seems to have been used for various skin conditions (psoriasis, acne, etc) and in general detoxification protocols more often than the other two.
Oregon grape shrubs can grow up to 6 feet in height. This bush has gray branches with 1-inch long leaves that appear gray underneath. They turn a golden color during fall.

Be careful if you harvest Oregon grape leaves, as they are very spiny.
Oregon grape grows in thickets and in pastures all along the Pacific Coast of North America. It also grows in rough, mountainous terrain eastward, including the Rocky Mountains.
Oregon grape root was once a valuable commodity because of its high berberine content. Berberine is one of the active ingredients found in goldenseal that helps bloodshot eyes and sore throats. Its popularity in trade led to its near extinction around cities near the beginning of this century.

In modern times, Oregon grape is known as a good liver cleanser. This is due to the fact that it increases bile production. This action also aids digestion and purifies the blood.
