TL;DR — Ayahuasca, psilocybin and other plant medicines have moved from the margins to the center of the conversation about mental health. What is driving the change, what the research actually shows, and what it means for someone considering a retreat.
Twenty years ago, ayahuasca was something you read about in anthropology books or heard about from a friend who had gone to Peru. Today it is discussed in medical journals, on the front pages of newspapers, and in the offices of therapists in New York and London. Something has shifted. This is our attempt, as a family that has held ceremonies in Costa Rica for more than a decade, to explain what that shift is and what it is not.
From the margins to the mainstream
The plants themselves have not changed. Ayahuasca, the brew made from the Banisteriopsis caapi vine and the leaves of chacruna, has been prepared in the Amazon basin for centuries. Psilocybin mushrooms have been used ceremonially in Mesoamerica for at least as long. What has changed is who is paying attention.
Since the early 2010s, universities including Johns Hopkins, Imperial College London and NYU have published clinical studies on psilocybin for depression, anxiety at the end of life, and addiction. Ayahuasca has been studied in Brazil and Spain for treatment-resistant depression and for its effects on the brain. The results have been promising enough that regulators in several countries have opened pathways for therapeutic use, and cities and states in the United States have begun to decriminalize plant medicines.
None of this means the science is settled. Most studies are small. The settings are controlled in ways a retreat is not. But the direction is clear: what was dismissed for decades is now taken seriously by people whose job is to be skeptical.
Why now
Three things came together. The first is a mental health crisis that the standard tools have not solved. Rates of depression and anxiety have climbed for years, and for a large share of people the available medications either do not work or come with side effects they cannot live with. When the usual answers fail, people look elsewhere.
The second is the research itself. Once serious institutions began publishing results, the conversation could move from belief to evidence, and evidence is what allows doctors, journalists and families to consider something they would otherwise dismiss.
The third is simpler: people talked. Someone came back from a retreat changed, and told their sister, their colleague, their doctor. Word of mouth built over years, and the internet made it visible. Most of the guests who sit with us heard about ayahuasca from someone they trusted before they ever read a study.
What "healing" means here
It is worth being careful with the word. Ayahuasca is not a pill you take and forget. It is a night, sometimes several, in which the ordinary defenses of the mind loosen and what is underneath comes up. For some people that is grief. For some it is fear, or anger, or a memory they had put away. For many it is a sense of connection that is hard to describe afterward without sounding like a cliché.
The healing, when it happens, is not in the visions. It is in what you do with them in the weeks and months after. That is why integration, the work of making sense of the experience and carrying it into daily life, is the part of a retreat we take most seriously, and the part most often skipped by centers that see ceremony as the product.
The risks nobody should minimize
A revolution attracts people who want to sell it, and the plant medicine world has its share. So it should be said plainly: ayahuasca is not for everyone, and it can be dangerous for some. It interacts with common antidepressants. It is unsafe with certain heart conditions, with epilepsy, and with a history of psychosis or bipolar disorder. A ceremony led by someone without experience, in a room with too many people and no one watching, is not a healing revolution. It is a risk.
This is why we screen every guest before we take a booking, why our groups never exceed five people, and why a facilitator stays sober and present for the entire ceremony. The awakening is real. So is the responsibility that comes with it.
What it means if you are considering a retreat
If the growing attention on plant medicine has brought you here, take it as an invitation to ask good questions, not as a reason to hurry. Read the research. Read what people who went say, including the critical accounts. Ask any retreat you consider how they screen, who leads the ceremony, how many people will be in the room, and what happens the morning after. The answers will tell you more than any headline about a revolution.
We are glad the world is paying attention to what these plants can do. We have watched it for more than ten years in the eyes of the people who sit with us. Our hope is that the attention brings more care, not less.
