Ancient Uses of Oregano

Greece is the first known place where oregano was used, it was even used by Hippocrates.  The ancient Greeks believed that oregano could be used as a poison antidote; as well as to treat skin irritations, dropsy, convulsions, and as an antidote for narcotic poisons.  

The Romans then started using oregano.  Their love of the flavor and its easy cultivation helped to spread it throughout Europe and to Northern Africa.

During the middle ages, oregano was commonly used for medicinal purposes throughout Europe. They would chew oregano leaves for rheumatism, toothache, indigestion, and coughing.

Oregano then made its way to China.  It was used there for medicinal purposes. The Chinese believed it helped with fever, vomiting, and upset stomach.

During the Elizabethan era, oregano was believed to encourage good luck and good health. 

Oregano did not become popular in the United States until after World War II when the soldiers were exposed to its culinary use in Europe.
