Black drink is a name for several kinds of ritual beverages brewed by Native Americans in the Southeastern United States. Traditional ceremonial people of the Yuchi,Caddo,Chickasaw,Cherokee, Choctaw, Muscogee and some other Indigenous peoples of the Southeastern Woodlands use the black drink in purification ceremonies. It was occasionally known as white drink because of the association of the color white with peace leaders in some Native cultures in the Southeast.
Black drink is consumed to purify an individual by removing spiritual and physical contamination and, as such, is never taken casually. The preparation and protocols vary between tribes and ceremonial grounds. The full formula is not published or given to outsiders, but a prominent ingredient is the roasted leaves and stems of Ilex vomitoria (commonly known as yaupon holly), a plant native to the Atlantic and Gulf Coasts. Black drink usually contains emetic herbs, which has been recorded as inducing vomiting.
According to the ethnohistorical record, the yaupon leaves and branches used for the black drink were traditionally picked as close to the time of its planned consumption as possible. After picking, historically they were lightly parched in a ceramic container over fire. The roasting increases the solubility in water of the caffeine, which is the same reason coffee beans are roasted. After browning, they were boiled in large containers of water until the liquid reached a dark brown or black color, giving it its name. The liquid was then strained into containers to cool, until it was cool enough to not scald the skin, and drunk while still hot. Because caffeine is 30 times more soluble in boiling water than room temperature water, this heightened its effect. It was then consumed in a ritual manner. Its physiological effects are believed to be mainly those of massive doses of caffeine. Three to six cups of strong coffee is equal to 0.5 to 1.0 grams of caffeine; the black drink could have delivered at least this much and possibly up to 3.0 to 6.0 grams of caffeine. However, this is erroneous. Owen gives the caffeine content of coffee as between 1.01 and 1.42 percent In comparison, Ilex vomitoria leaves contain 0.0038 to 0.2288 percent caffeine by weight according to experiments performed by Adam Edwards in 2002. Similar methods of production were adopted by European colonists for the production of a drink that often shared the same names with Native names for the black drink but used for different, secular purposes.
