Morning glory Folklore & Trivia

The seeds contain ergoline alkaloids, and have been used for centuries by many Mexican Native American cultures as a hallucinogen; they were known to the Aztecs as tlitliltzin, the Nahuatl word for “black” with a reverential suffix. In South America, the seeds are also known as badoh negro.
Ipomoea purpurea does not sequester ergot alkaloids in its seeds. The alkaloids are apparently produced by a fungal symbiont.
