Answer 3

Indians in the eastern United States believed a variety of things, but there were common beliefs that were shared among numerous tribes, especially in the Mississippian era. Historians and archaeologists refer to this as the Mississippian Ideological Interaction Sphere or the Southeastern Ceremonial Complex. It was believed that there were numerous spiritual powers just about everywhere, including spirits of the sky (Master of Breath, Red Horn, Thunderbird, Birds, the Sun), the earth (Cornwoman, Lucky Hunter, Animals, Plants, the Sacred Fire), and the Underworld (Underwater Panther, Horned Serpent, Spider, Medicinewoman In The Moon). People such as the Chickasaw, Choctaw, Cherokee, Muscogee, and Natchez all used to use Ilex Vomitoria (Yaupon Holly) in a ceremonial beverage called Black Drink, or alternatively White Drink. It would be drank in large amounts out of a conch shell before ritual vomiting because of (1) the amount of liquid ingested, and (2) the amount of caffeine in the tea. This was often done before war to give warriors strength for battle. Women never consumed it (except for female Timucuan chiefs), but they are reported making the drink. Many tribes participated, and still participate, in the Stomp Dance, which culminates in the Green Corn Ceremony as the corn is ready to harvest in summer.
