  ## Uses
  
  This plant has historically been used as a natural sweetener and medicinal herb in its native Mexico and parts of Central America. It was used by the Aztecs and introduced to the Spanish when they arrived.
  
  The sweet taste is caused by a sesquiterpene compound called hernandulcin, which was discovered in 1985 and named for Francisco Hernández, the Spanish physician who first described the plant in the sixteenth century. Use of Phyla dulcis has not become widespread because it also contains high levels bitter compounds, especially camphor.
