Sacred mushrooms, ancestral medicine, and the science finally catching up to what the grandmothers never forgot
Before the clinical trials. Before the neuroscience journals. Before the podcasts and the retreat centers and the breathless headlines — there was a woman on a mountainside in Oaxaca, chanting through the dark. Her name was María Sabina. She called the mushrooms los Niños Santos. The Holy Children. And she had been sitting with them, healing her people, long before the Western world came looking.
The story of sacred mushrooms is, at its root, a story about what happens when one way of knowing gets buried under another. About what persists in the body of the earth, and in the bodies of the people who tend it. And about what we are all — slowly, imperfectly — beginning to remember.
Written in Stone: The Deep Record
The oldest known images of sacred mushrooms are not found in a library. They are painted on cave walls.
In Tassili, Algeria, cave paintings depicting Psilocybe mairei mushrooms have been dated between 7,000 and 9,000 years before the present. The figures in these paintings blur the boundary between human and fungus — a therianthropic imagery that scholars associate with states of ego dissolution and unity with the natural world. Rock paintings in Spain, created roughly 6,000 years ago, suggest that Psilocybe hispanica was used during religious rituals near Villar del Humo.
Evidence suggests their use in diverse cultures across Africa, Europe, and the Americas, each weaving these fungi into their unique spiritual frameworks. The relationship between humans and psilocybin is not a modern experiment. It is one of the oldest conversations we know how to have.
The Mesoamerican Record
Nowhere is the archaeological record more sustained than in Mesoamerica. Mushroom stone effigies, dated to 1,000 BCE, give evidence that mushrooms were at least revered in a religious way among the ancient Maya. These small carved figures — found across Guatemala, Ecuador, and southern Mexico — are understood to be effigies of a mushroom deity.
The Codex Vindobonensis Mexicanus I, a 15th or 16th century pictographic manuscript created by Mixtec people from Oaxaca, Guerrero, and Puebla, portrays an ancient pre-colonial mushroom ritual — probably referencing a calendrical adjustment during the sacred times before the first dawn. In it, deities each carry two mushrooms in their hands, reflecting the Mesoamerican understanding of sacred duality.
Teonanácatl · Flesh of the Gods
Among the Aztecs, psilocybin mushrooms were known as teonanácatl — most often translated as “flesh of the gods.” The Florentine Codex, a 16th-century colonial text that preserves Aztec sources, describes a mushroom ceremony in which participants ate the mushrooms with honey as shell trumpets were blown. When the effects came, participants danced and wept. When the effects lifted, they gathered to share what they had seen in vision — what would befall those who had not eaten the mushrooms.
For many Indigenous communities, psilocybin mushrooms were never considered “drugs” but sacred medicines. Shamans and healers used them to communicate with spirits, guide their communities, and diagnose illness. The altered states induced by psilocybin were viewed not as escapism but as a doorway into a deeper layer of reality — where ancestors, gods, and natural forces could be encountered.
Then the Spanish arrived. Spanish missionaries in the 1500s attempted to destroy all records and evidence of the use of these mushrooms. Many Indigenous communities were forced to abandon open mushroom ceremonies, retreating into secrecy to preserve their traditions. Despite suppression, the ceremonies persisted — carried in the bodies and memories of those who would not let them go.
She Who Looks Inside and Examines
To speak honestly about who carried this knowledge through centuries of suppression, we have to speak about women. About grandmothers. About the ones who held ceremony in the dark, whose names were never written down, whose work never received a publication credit.
And we have to speak about María Sabina.
The Life of María Sabina (1894–1985)
María Sabina Magdalena García was born on July 22, 1894, in Huautla de Jiménez, a town in the Sierra Mazateca of Oaxaca, Mexico. She was a Mazatec sabia — a wise woman — who spent her life facilitating sacred mushroom ceremonies called veladas, using Psilocybe caerulescens, a mushroom held as sacred by the Mazatec people.
She participated in her first velada at the age of seven, introduced to the practice through her father, who was himself a healer. She intuitively developed knowledge of ancient Mazatec rituals and the healing power attributed to the ritual intake of the Mexican Psilocybe mushroom, which grows only in the Sierra Mazateca. She called them her Niños Santos — her Holy Children. “I am the woman,” she said, “who looks inside and examines.”
Her life was not easy. She survived the early death of her father, two marriages — one to a man who was controlling and violent — and the deaths of most of her children. It is said that the mushrooms healed her and gave her strength during her years of abuse. When her sister fell gravely ill and every local healer said she would die, Sabina held ceremony. Her sister recovered. Word spread. A vocation was confirmed.
“The Mazatec sacred mushroom veladas were not merely a healing ritual but a days-long introspective and therapeutic process — not a recreational trip, but a deep return to the self.”
— Inoculate the WorldThe intention of the all-night velada was to commune with God to heal the sick. The spirits, if effectively contacted, would tell Sabina the nature of the illness and the way it could be healed. Each participant ingested psilocybin mushrooms as Sabina — who typically consumed twice as much — chanted invocations to coax forth the divine.
A lifelong Catholic, she wove Christian language into ancient Mazatec ritual without contradiction, as healers across traditions have always done — working with what the living moment requires. 
The Encounter That Changed Everything
In 1955, R. Gordon Wasson — an American banker and amateur ethnomycologist — arrived in Huautla in search of those who still performed the mushroom ceremony. He was brought to Sabina. She had already performed the velada for more than 30 years. His reluctance to introduce Wasson to the ceremony had less to do with his being a foreigner and more to do with the fact that Wasson wasn’t sick — he had come seeking God, not healing.
Wasson’s subsequent article in Life magazine in 1957 brought María Sabina and the sacred Mazatec rituals to the attention of the Western world. What followed was a flood. Timothy Leary came. Legends suggest John Lennon and George Harrison came. Hippies filled the neighboring villages. Bad trips destabilized the town.
The publicity was disastrous for the Mazatec community. Sabina’s house was burned down. Federales raided her home, accusing her of selling drugs to foreigners. She was ostracized. She accepted her fate as if it had been pre-determined — but she regretted opening the ceremony to those who did not require healing. “From the moment the foreigners arrived,” she said, “the holy children lost their purity.”
Despite her invaluable contributions to the world, María Sabina died on November 23, 1985, in poverty and suffering from malnutrition. Her great-grandson later requested that her remains be moved to a burial worthy of one of the most recognized healers in history.
Her story is not simply an origin story for the psychedelic movement. It is a story about what extraction looks like — and what is owed to those who held something sacred long before we arrived to receive it.
The Laboratory Arrives at the Ceremony
The compound that gives sacred mushrooms their visionary quality — psilocybin — was not isolated until 1958, when the Swiss chemist Albert Hofmann identified it from samples collected among the Mazatec. His employer, Sandoz, began marketing and selling pure psilocybin to physicians and clinicians worldwide for use in psychedelic therapy. Then came the 1970s, the Controlled Substances Act, and decades of prohibition that effectively ended research.

What the Research Is Showing
Beginning in the early 2000s, a growing body of clinical research has quietly reversed the narrative. Pioneering research at Johns Hopkins, beginning with Roland Griffiths’ landmark 2006 psilocybin study, helped spark interest in psychedelics as a fundamentally different approach — one that might break the cycle of depression with a single transformative experience rather than daily medication.

First Phase 3 psilocybin trial data cleared the bar for treatment-resistant depression, 2025–2026
A Phase 2 study by Compass Pathways found that a single 25 mg dose of synthetic psilocybin was well tolerated with no serious adverse events, and indicated both rapid and durable improvement in PTSD symptoms observed out to 12 weeks following a single administration.
The FDA has designated deuterated psilocybin as a breakthrough therapy, recognizing its potential to address the unmet needs of patients with major depressive disorder. That designation — “breakthrough therapy” — is the clinical world’s way of saying: this is something we need to move on quickly.
What the research is also finding — and this matters — is that the quality of the relational container shapes the outcome. Psilocybin appears to enable a broad, indirect engagement with traumatic material via affective, somatic, and self-transcendent experiences — moments of perceived unity, dissolution of self, or felt connection with something larger than the individual. The medicine works not through brute pharmacology alone, but through the opening of a particular kind of interior space. A space that the velada was designed to create.
Sabina knew this. The Mazatec knew this. The grandmother-healers whose names we will never recover knew this.
What We Owe the Tradition
The psychedelic renaissance is real. The science is compelling. The need is urgent — depression, PTSD, addiction, and trauma are taking lives at rates our current medicines cannot address. None of that makes the path simple.
Because behind every clinical trial, there is a lineage. And behind that lineage, there are people who paid a price for what they carried.

On Reciprocity
Engagement with sacred mushroom work — whether in a clinical setting, a ceremonial context, or through personal practice — calls for an orientation of reciprocity rather than consumption. This means learning the history without sanitizing it. It means understanding that the Mazatec tradition, the Mixtec codices, the velada — these are not metaphors. They are living practices belonging to living people and communities who have not yet received adequate acknowledgment, much less restitution, for what was taken from them.
It means asking, before you step into any container with these medicines: Who tended this path? What do I owe them? How do I show up in a way that honors rather than extracts?
On Discernment
If you feel called toward psilocybin work — whether through clinical trial, legal therapeutic setting, or ceremonial tradition — discernment is your most important preparation. Not every facilitator is a healer. Not every ceremony is a safe container. Not every legal framework offers genuine access to the depth of this medicine.
Look for facilitators trained in trauma-informed practice. Look for ceremonial leaders who carry genuine lineage and community accountability. Look for spaces where preparation and integration are taken as seriously as the experience itself. The medicine is not the whole of the path — the relationship you bring to it is.

On Legality
As of 2026, psilocybin remains a Schedule I controlled substance at the federal level in the United States. Oregon has moved toward regulated therapeutic access; several cities have decriminalized possession. Clinical trials are ongoing. The legal landscape is shifting, but unevenly. Always orient yourself to the laws of your specific jurisdiction, and prioritize your safety and community relationships in any decision-making.
