Evidence of gum chewing also dates back to prehistoric men and women who chewed on tree resin for enjoyment. Greek and Middle Eastern cultures routinely chewed resin from the mastic tree to freshen their breath. In Central America, the Mayans enjoyed chewing on chicle sap. This Central American tree resin was the basis for modern chewing gum. In the United States, Native Americans and settlers first chewed on spruce tree resin and beeswax. In New England, spruce sap was used to make America’s first gum. In 1848, John Curtis used resin to make State of Maine Spruce Gum. He sold two hunks of the gum for a penny.
