Basic Habitat / Botany:
Cornus is a species of 30-60 plants, commonly known as dogwoods. The Western dogwood and Chinese cornus are in the same plant family but have somewhat different healing properties. The dogwood tree is a flowering tree bearing pink or white flowers. In the fall, bright red berries appear at the point where the leaves meat the branches. Cornus is a shrub that can grow to be 30 feet tall. It has fleshy, green oval-shaped leaves and small, berry-shaped fruit. It has small inconspicuous yellow flowers that will appear in late winter and early spring. The fruits of all dogwood trees are drupes.
Cornus is native to China, Korea, and Japan. It prefers the woodland regions of East Asia from China to Korea. The Western species, Cornus florida, is native to various parts of the United States.

History/Folklore: Cornus berries (or fruit) have a long history of being used in Traditional Chinese Medicine as a tonic and astringent herb.

It is especially identified with tonifying kidney system functions including impotence, irregular menses, spontaneous sweating, low back and knee pain, dizziness, and even the effects of shock and trauma. Cornus fruit can also act as a urinary antiseptic.
Cornus bark is astringent and most often used to treat fevers (including typhoid fevers) and malaria. The high tannin content has led the herb to be used as a substitute for quinine. During the American civil war confederate soldiers would make tea from the bark to treat pain and fevers, and a poultice made from the leaves was used to cover wounds.
When using the Western species, Cornus florida, it is the bark of the branches and roots that are most commonly used and the root bark is considered the strongest and most effective for making medicines. Like Cornus officinalis, this species is also a tonic and astringent herb.
