@congareenps: "The leaves of the Yaupon holly were used to make a tea drink that was a part of Native American purification rituals. European explorers witnessing these ceremonies gave the evergreen shrub the unfortunate scientific name of Ilex vomitoria, due to their belief that it was an emetic. Despite the name, drinking yaupon tea will not make you ill, and was once quite popular. Recent studies have shown that yaupon leaves contain #caffeine and #antioxidants commonly found in #coffee and other teas. Maybe you will see it at your local #coffeeshop in the near future! #FindYourPark #nps #nature"
