History/Folklore: The constituent berberine has had considerable attention paid to it and been the source of many studies. It is this bitter chemical that puts Oregon grape at the top of the list for many herbalists. Berberine is famous for decreasing bacterial resistance to antibiotics and aiding longevity. It is known for reducing blood glucose levels, stopping infections and moderating inflammation. Berberine alkaloids act on the DNA of cells to prevent amoebas from taking hold in the body. Berberine is what gives Oregon grape roots their yellowish color. Berberine is found in every part of the plant from the flowers to the roots. In Traditional Chinese Medicine, plants with berberine are often used to treat what are called Damp-Heat conditions.

Another constituent in Oregon grape is berbamine which helps strengthen bone marrow and aids the recovery from chemotherapy and radiation treatments. It is a calcium channel blocker that inhibits the growth of cancer cells. Traditional Chinese Medicine has made use of plants with this constituent for centuries to treat conditions caused by inflammation, including rheumatoid arthritis.

Oregon grape is a classic bitter herb.  Bitter herbs are known for their ability to detox and for supporting the secretion of bile from the liver and gallbladder which helps to aid digestion, especially the digestion of fats.

Native Americans used a decoction of the root to treat loss of appetite and debility. They also used it to treat tuberculosis, rheumatism and jaundice. They also used the root to make a yellow dye for baskets and clothing. The berries were also used to make jelly.

In the Southwest, Spanish colonials used the species M. fremontii calling it “Palo Amarillo” or “Fremont’s barberry.” They used it to treat fevers, hepatitis and malaria.

Oregon grape is excellent for treating wounds as it will help keep the area free from infection and swelling. The plant’s antimicrobial properties also make it a wonderful herb for treating lung and sinus infections.

The herb was used as a cure against syphilis. Many physicians felt it worked best if the condition had become chronic.

Traditionally the herb is prepared by either using the roots to make teas or tinctures. Used externally, oregon grape helps fight psoriasis.

In China, the herb coptis is often substituted for oregon grape. Seventeen different varieties of Berberis are used, all containing the constituent berberine. They are primarily used to treat intestinal infections and to stimulate the uterus.

The herb Barberry (Berberis vulgaris), also known as Berberry, Pipperidge, Jaundice Berry or Sow Berry, is a member of the same Berberidaceae family of plants as Oregon grape (Berberis aquifolium or Mahonia aquifolia), but it is in fact a different plant. Barberry is a thorny, deciduous shrub that can grow to be ten feet tall with leathery leaves, yellow flowers and red berries. These two plant species are often used interchangeably, though Oregon grape is considered the stronger and more restorative of the two species. It is also more focused on the liver than barberry.

Closely related to the herb barberry (Berberis vulgaris), Oregon grape (Berberis nervosa) adapts more easily to its environment, making it easier to grow in your garden.
