María Sabina is probably the most famous shaman in Mexico. A Mazatec Indian, she was reluctantly turned into a celebrity after her meeting with the banker and mushroom scholar Gordon Wasson.
María unintentionally ended up at the center of a debate (unrelated to her culture) about the legal and open use of psychoactive substances. Called the Holy Children, these mushrooms grow in the virgin mountains of Oaxaca (and in many other parts of the world such as Siberia or Galicia). The Mazatecs feel love and reverence for them.
