“Yaupon” is derived from the Catawban tribe’s word “yapa,” which means “leaf of the tree.” In Florida, Timucua people referred to it as “asi,” which loosely translates to “the purifier.” In addition to drinking yaupon tea casually “they used yaupon frequently as a part of pre-battle rituals to give them energy, making a tea known as black drink and consuming it in large quantities,” Bryon says.
