Corktree Background and Benefits

Corktree is a common name for Phellodendron amurense, which is a tree in the Rutaceae family. It is native to eastern Asia, especially northern China, Japan and Korea. Corktree has also become naturalized in North America, where it is considered to be an invasive species in some jurisdictions.

Corktree is so named for its corky bark, which turn dark gray as the tree matures. It can reach a height of 50 feet and has a wide crown, especially in older trees. This species is deciduous, so the leaves turn yellow in the fall. The black berries have a diameter of 3/8 inch and stay on the tree until winter. Each berry contains five seeds.

Corktree is generally well-adapted to temperate climates, which includes USDA Hardiness Zones 4 through 7. It can tolerate cold and drought, and often thrives in a variety of soils. However, corktree produces significantly more fruit in good soil with ample water.

The bark is generally the most important part of the corktree in herbal medicine. It contains many biologically active components, with berberine being one of the most significant. Berberine is chemically classified as a protoberberine, which is a group of isoquinoline alkaloids. Its primary biochemical actions include the suppression of cytokines, which provoke inflammatory responses.
