History: Although not particularly common, Celtis occidentalis is currently found throughout the eastern and midwestern US and Canada and in parts of Australia. It is cultivated in other parts of the world. Native American tribes used the bark of the tree medicinally for treatment of colds, sore throat, jaundice, venereal disease, to regulate menstruation, and to induce abortion. Its fruit was consumed as food and used as spice and its wood burned as fuel ceremonially. Although weak, its wood is sometimes used to make fences and inexpensive furniture. A dye can be obtained from its roots.
