Ololiuqui

Ipomoea corymbosa, also placed in Rivea and Turbina, is a species of morning glory native throughout Latin America from Mexico as far south as Peru and widely naturalised elsewhere. Its common names include Christmasvine, Christmaspops and snakeplant. It is known to natives of north and central Mexico by its Nahuatl name, coaxihuitl, and in Mayan as xtabentún. It is a perennial woody climbing vine with white flowers. The flowers secrete copious nectar, and the honey bees make from it is very clear and aromatic. Natives of Mexico consider the flour produced from its seeds, called ololiuhqui, meaning round thing, a tool for divination and communion with spirits. The seeds contain ergine, also called LSA, an ergoline alkaloid that is also present in ergot and is similar in structure to LSD. Because of the widespread use among native tribes, Colonial rules initially feared ololiuhqui and banned it, introducing harsh punishments for users.
