Psilocybin mushrooms have been used in sacred ceremony for thousands of years, most famously documented in the Mazatec tradition of Oaxaca, Mexico, through the work of curandera María Sabina. Today, they are among the most studied psychedelic compounds in clinical research, with strong evidence for reducing depression, anxiety, and existential distress.
At Mariri, mushroom ceremonies are offered as a gentler entry point into the plant medicine world — particularly suitable for those new to expanded states, or those seeking a reflective, emotionally focused experience without the full physical intensity of ayahuasca. Sessions are held in ceremony with intention, music, and facilitated support.
Psilocybin works primarily by temporarily quieting the default mode network — the part of the brain responsible for rumination and fixed self-narrative — while increasing connectivity across regions that don't normally communicate. The result is often a softening of rigid patterns, fresh perspective on long-held beliefs, and a renewed sense of meaning and connection.
Ceremonies typically last 4–6 hours. Our facilitators remain present throughout, providing music, guidance, and grounded support as needed.
