Mazatec curandera María Sabina in Oaxaca, Mexico, conducted healing veladas using sacred mushrooms (teonanácatl), inducing collective visionary states. Her chants guided participants to spirit realms. Exposure to Westerners like Wasson popularized it globally. It mattered by preserving indigenous knowledge amid modernization.

María Sabina's veladas with psilocybin mushrooms in 1955 influenced a generation of poets, including Allen Ginsberg, who drew on her rituals to explore themes of healing and visionary experiences. This intersection of indigenous practices and modern poetry enriched Latin American and global literary landscapes.
