Retreats · Colombia, Brazil & Europe
Plant medicine retreats,
held where the medicine
actually comes from.
One is open. Three are forming.
Colombia, in Kamentsá territory — with the preparation and integration that decides whether any of it holds. Because the ceremony is not where it is decided. The Tuesday afterwards is.
Brazil with the Yawanawá, psilocybin and European containers are waitlist — dates go to the list first. Every retreat includes Rosa's screening, preparation and integration. Nothing is sourced, supplied or administered.
Three medicines.
One standard of care.
Each medicine carries its own cosmology, lineage, and way of working. None is superior. Each calls different people at different moments. Understanding which one is calling you is part of the preparation.
Ayahuasca
The brew of Banisteriopsis caapi and DMT-bearing leaves — held by Shipibo, Yawanawá, and Cofán lineages. Night ceremony, icaros, purga. The deep dissolution and reassembly of the self.

Teonanácatl — the sacred flesh. Mazatec veladas, María Sabina's lineage, dendritic spine regrowth and structural rewiring. The mycelium intelligence that dissolves the walls between self and world.
Full Guide →Mescaline
Phenethylamine of the sacred desert — heart-open Wachuma rising with the Andean sun, Peyote carried through the Wixarika pilgrimage. Two traditions, one molecule, 5,700 years of relationship with the land.
Full Guide →Held by experts who work in
integrity with both the medicine
and the territories.
Every retreat and ceremony I support is held by practitioners who meet a standard I would want applied to me. Not a certificate on a wall. An ongoing practice, real supervision, and a living relationship with the communities and lands the lineage comes from — the kind you cannot acquire in a fortnight.
Facilitators who continue to work with the medicine themselves, not as a credential, but as part of their living relationship with it. The container is only as clean as the person holding it.
Ongoing clinical and peer supervision. No facilitation work should be done in isolation. Supervision is the container for the facilitator — the place where difficulty, projection, and counter-transference are worked, not buried.
Deep, ongoing relationship with the communities, elder teachers, and territories where the medicine is held. Reciprocity is not a donation box — it is sustained presence, material contribution, and accountability.
Somatic, attachment-aware, and nervous-system-informed facilitation. Difficult experiences are accompanied — not reframed away, not bypassed. Every participant's history is known and held before the container opens.
The same person,
the whole way through.
You will not meet me on a screening call and then be handed to a stranger in ceremony.
I prepare you. I am there for the eight days. And I am there afterwards, when the real work starts and everyone else has gone home.
In this field, preparation and facilitation are routinely done by different people who have never spoken to each other. You do the vulnerable part — the medical form, the history, the actual reason you are going — with one person. Then you walk into the room and meet somebody else entirely.
Your nervous system notices. It was told this was safe, and then the face changed.
That is not a scheduling detail. In trauma-aware work the felt sense of safety is the container, and continuity is most of how you build one. So there is no handover here. There is just me, the whole way through.
I have published that second one exactly as it arrived, opening clause and all. If a page about plant medicine only ever shows you people who are enthusiastic about plant medicine, you are not reading a testimonial. You are reading an advert.
CJ
When I got out of the Army, I had no idea how defined by trauma my life was. There are a lot of us who join in the first place because in some way or another we feel as though we haven’t been prepared for anything else. The chronic tension and injury we take on becomes glorified, instead of seen as a disease. We hold onto our sense of insufficiency and let go of everything else. Feeling safe becomes a form of weakness. It’s the reason so many people stay in and believe they have nowhere else to go, and it’s also the reason 26 veterans commit suicide a day in my country. I was inching closer to that statistic every day before I met Rosa. When the environment that protects your most toxically functional insights is gone, there’s nothing to really do but feel empty.
Ayahuasca completely dismantled every belief I’d ever held, giving me the power to step back and understand which ones would serve me in the future. So much of my energy for years had gone into making sure there was no relationship between my mind and body. I had sacrificed relationships to protect my insecurities. I had self-sabotaged my way out of feeling successful. I had blamed myself for decades of abuse in order to keep myself from feeling victimized.
It’s difficult to watch your entire psyche melt in front of you and realize your “strengths” are the thing that’s killing you and the ones you love. I don’t have words for how grateful I am that Rosa was with me. It’s truly rare to find compassion as authentic, pragmatic, and informed as hers.
If fear is holding anyone back from embarking on this journey with her, it’s understandable. It’s scary as hell.
I would ask you, though, to sit with that fear and discomfort for a minute. What are you afraid of having question in your life? What parts of yourself, or your relationships, or career, or past are you afraid to look at? I’d encourage you to take a chance on yourself, and to let Rosa take a chance on you too. You’re worth it.
CJ’s account names suicide. If that is close to home for you as you read it — US veterans, service members and their families: dial 988 then press 1, text 838255, or chat at veteranscrisisline.net. Anywhere else in the world: findahelpline.com lists verified crisis lines in over 175 countries.
Every quote here was written months after the work ended — sometimes more than a year. Never in the afterglow. I don’t ask then, and I wouldn’t accept one if it were offered.
Screening, Preparation &
Integration — by Rosa F. Brissos, PhD
Every retreat and ceremony offering in this ecosystem includes access to Rosa's structured screening, preparation, and integration process — delivered individually. This is not a support group. This is not passive listening. This is not spiritual aftercare dressed in soft words. It is a rigorous, neuroscience-informed, somatic, and relational process that begins weeks before ceremony and continues long after.
Because medicine work does not begin when the ceremony starts. And it does not end when the ceremony closes. Preparation creates the vessel. Integration turns revelation into embodiment. It is where insight becomes behavior. Where emotion becomes capacity. Where the nervous system receives enough safety, structure, and repetition to make change possible.
Without preparation, ceremony can become intensity. Without integration, insight becomes another beautiful thing your nervous system forgets.
Before anything else: is this right for you, right now? This is a rigorous assessment — not a gatekeeping exercise, but a genuine care process.
The space between deciding to go and stepping into ceremony is where much of the real work happens — if it is held properly.
The ceremony is a door. Integration is what happens when you walk through it — and keep walking, for months, until what was shown becomes lived.
Every retreat, and exactly
which ones you can book.
Each offering below is held in integrity — with its tradition, its territory, and the people called to it. All include Rosa's preparation and integration program. One is open for applications right now. The rest are waitlist or in development — labelled honestly, so you know what you are actually looking at.
Eight days. Five people.
One vine.
A yagé retreat held by the Kamentsá lineage in their own territory, at Shanayoy Healing Center in the Sibundoy Valley — led by Taita Mayor Juan Bautista Agreda and his family. Rosa goes as a guest. She does not hold the ceremonies and claims no authority in that tradition.
What she brings is five properly prepared people and the work that happens either side of the ceremony — which is where it is actually decided. Most people don't come back changed. They come back impressed. The difference is everything arranged around the six hours.
Yawanawá,
Aldeia Nova Esperança · Acre
A 10-day immersion in Yawanawá territory — a cultural exchange built on a recently established relationship, not a retreat product. Ceremony, medicine plants, song, and life in the forest with one of the Amazon's most intentional communities.
Ceremonies are held by Chief Iskukua Biraci Jr. (Caçique who leads Aldeia Nova Esperança) or Chief Biraci Jr. Isku Kua — Guardians of two of the largest villages in the Yawanawa community, which sits 7 hours deep into the real forest at an Indigenous Territory. Sanctuaries shielded from urban influence, deeply rooted in ancestral culture and spirituality. A rare opportunity to learn directly and immerse yourself in the wisdom of the Yawanawa lineage.
Psilocybin
Mushrooms
Small, carefully held psilocybin containers in legally permissive jurisdictions.
These are not casual psychedelic experiences. They are deeply prepared, trauma-aware ceremonial spaces designed for people who understand that altered states require safety, discernment, and integration — not performance, fantasy, or spiritual bypassing.
We honour the Mazatec tradition as an ancestral lineage of mushroom wisdom, while weaving it with a Western therapeutic, nervous-system-informed, and scientifically grounded approach. This is work with the intelligence of the mycelium — not around it.
A space where soul and science meet. Where ceremony is held with rigor. Where the body is listened to as much as the vision. Where the medicine is not treated as a shortcut, but as a relationship.
For those called to meet psilocybin with preparation, reverence, and a structure strong enough to hold what may emerge.
Wachuma
San Pedro · Andean
Facilitated by Rosa herself — daylight ceremonies with a fully open heart. She honours the Andean tradition while integrating a Westernised approach that brings people back to presence, joy, and embodied clarity, without bypassing the medicine's spiritual depth.
Ceremonies held
closer to home.
For those who cannot travel to South America, or who wish to work within European rhythms — a small, carefully held container in legally appropriate European contexts. Same standard. Same depth. Same integration.
Facilitators are practitioners who engage in regular supervision, ongoing personal practice with the medicine, and nurture active relationship with both the medicines, the territories, and the communities from which their lineage descends. These are not retreat hotels. These are held spaces.
Rosa F. Brissos, PhD, and every facilitator she collaborates with, have been working with cooperative groups and members, culturally diverse groups, people with cPTSD, people coming from war zones, veterans, and survivors of physical and psychological abuse. She is currently organizing retreats specialized for the corporate world — focused on productivity, longevity, and well-being —.
If you are interested in bringing your group, your organization, or your community, contact Rosa directly.
