Aboriginal Coffee, Coffee Beans and Tea
Coca, Tea, Dandelion root, and Yaupon was already extensively traded in the Eastern side of what is now America 1,000 years ago!
Caffeinated plant native to the Southeast, where Native Americans brewed it into a drink used ceremonially, often in rituals that involved purging though it is not an emetic. Several years ago we found traces of caffeine - from drinks made with Yaupon Holly - at a site of a mound city near the confluence of the Missouri and Mississippi rivers. Native Coffee beans and tea.
