Psilocybin mushrooms, often called "magic mushrooms", are a group of fungi containing the psychoactive compounds psilocybin and psilocin. Revered for millennia by Indigenous cultures (the Aztecs and Mazatecs called them teonanácatl, "flesh of the gods"), they produce altered states used for healing, divination, and spiritual connection. This guide covers what they are, how they work, their effects, the legal picture, and the science. At Lunita, mushroom ceremonies are held within this traditional, grey-area context, more below.
What are psilocybin mushrooms?
They're a polyphyletic group of fungi, over 200 species, with Psilocybe cubensis among the best known, that contain psilocybin and psilocin. Far from mere recreational substances, they've been treated as sacred fungi across cultures, approached with intention and ceremony. (The cross-cultural history is here.)
How psilocybin works
Once ingested, psilocybin converts to psilocin, which acts on serotonin 5-HT2A receptors. One key mechanism: it temporarily quiets the brain's default mode network (DMN), the system tied to self-referential thought, rumination, and ego, producing a more interconnected brain state, novel perspectives, and a sense of unity. This neurobiology underpins both the spiritual experiences and the therapeutic effects under study.
The effects
Effects vary with dose, physiology, mindset, and setting, but commonly include perceptual shifts (enhanced colors, geometric patterns, synesthesia), emotional amplification, ego dissolution (a felt oneness), mystical experiences (sacredness, transcendence of time and space), and cognitive insight that can lead to lasting change. Reverence, preparation, a clear intention, and a supportive setting are essential.
Spiritual significance
For thousands of years, mushrooms held a central place in Mesoamerican spiritual life, used by shamans and curanderos in sacred containers for healing and divination. That lineage runs through the Mazatec curandera María Sabina, whose veladas brought the tradition to the world's attention. Today's "psychedelic renaissance" is, in many ways, modern science catching up to what these traditions long understood.
The legal picture
Psilocybin is a controlled substance in Mexico (and Schedule I in the US), but traditional ceremonial use, rooted in the Mazatec velada and other Indigenous practice, has long occupied a tolerated grey area, and a 2021 Mexican Supreme Court ruling on personal autonomy adds further context. This is not legal advice. For why many people choose to do this work in Mexico, see Mexico vs. a US psilocybin retreat.
How Lunita relates to mushrooms
Lunita facilitates mushroom ceremonies within this traditional, grey-area context, with screening, experienced facilitation, and integration woven through a personal retreat.
