Beakers found at Cahokia in the Midwest contain
traces of tea from the southeast
Some teas are not as soothing as others. “Black drink,” brewed from the holly Ilex vomitoria by Native Americans on what is now the southeastern coast of the United States, had the lovely side effect of inducing vomiting (though perhaps from ingredients other than the holly) and was a key part of a 16th-century religious purification ritual, according to European accounts. Researchers were recently surprised to learn, however, that it also seems to have traveled quite a bit: traces of black drink have now been found over 200 miles out of Ilex vomitoria’s coastal range at the site of Cahokia, an ancient city near modern-day St. Louis.
