The drinking of yaupon goes back into the time of the ancients, before the cataloging of history and the arrival of Europeans in the New World. Yaupon, the only caffeinated plant native to North America and a relative of yerba mate and guayusa, is an inconspicuous little evergreen that grows along the coastal regions of the Southern United States and the Atlantic coast. It takes on a variety of forms, from small bush to little tree, and its name actually comes from the Catawban language, meaning “little tree.”
