Horseradish is native to Europe, but long ago spread to western Asia. The plant is a perennial and member of the mustard and cabbage family. It has deep roots, large leaves, and grows to twenty inches. Despite only growing to twenty inches tall, it can produce leaves two feet long and six inches wide.
Horseradish is a popular condiment in many parts of the world. It is one of the five bitter herbs consumed at Passover seder.
The Cherokee used the plant to treat asthma, coughs, and bronchitis. Many tribes, including the Ontario, Delaware, and Mohegan, have applied poultices of the leaves to treat neuralgia and toothache.
