Oregon grape is the fruit from the Mahonia aquifolium or Berberis aquifolium shrubs that is found in northern and coastal states of America. It is also the state flower of Oregon. While the shrub is generally utilized as an ornamental plant, the flowers, berries, leaves, and roots have traditionally been used by Native American tribes as food and medicine.
The fruit or berries can be eaten raw, cooked, or preserved as a jelly or dried fruit, akin to blackberries or blackcurrants. The flowers are edible and can be used as a decoration or drink infusion. Most of the medicinal properties are derived from the roots and leaves, due to the presence of berberine.
Berberine is a yellow-colored alkaloid that has possible therapeutic use in metabolic syndrome, type 2 diabetes mellitus, dyslipidemias, and cancer. It is also used as a dye for coloring textiles.
