Is sassafras tea carcinogenic?
Prior to the discovery that sassafras contains a carcinogen, it had a long and widespread history of use as a folk medicine. Native Americans used sassafras to cure many different conditions, but especially as a spring blood tonic. Before long, Native Americans introduced the European settlers to sassafras. It became a sought-after herb in Europe. Sassafras root bark was imported from the United States, and sassafras trees were also planted in Europe. Sassafras tea, sold under the name saloop, was a popular beverage in London.
