Why working with us

We are a passionate and seasoned tribe. We offer healing retreats and Practitioner Training for aspiring facilitators of Ancestral Medicines. Our retreats are specifically crafted for people seeking healing and with an interest in discovering the deeper aspects of their true selves. Our mission is to share, help disseminate and preserve the collective wisdom found in the teachings and practices of traditional healers of Central and South America. We dedicate our spiritual and human capital to support healing and the evolution of consciousness.

Healing and Empowerment

Our focus is the empowerment of others through the use of ancestral medicines and their unmatched capacity to help us heal & reconnect. We insist on sharing these medicines in the way of the elders. We owe everything to the wisdom holders of this world, the curanderos, vegetalistos and shamans of many traditions. And we are similarly inspired and driven by their ways of reciprocity with nature.

We Bridge Worlds

We believe that we are in a unique position to offer you a way to deeply rewarding work with master plant medicine as we are westerners who share a culture, language, and mindset with you. Decades of personal work with shamanism, plant, and earth medicines have also made us initiates of a kind:—shamanic practitioners, intuitive & facilitators—and allowed us to craft a way for the western mind to navigate and dialogue with the wonders and healing energies of Ancestral Medicine.

Our Retreats

The Indigenous Way

Our intention is to share the ancestral ways of healing where preparation, diet and intentional mindset are paramount to enter pure states of awareness and to heal physical, mental and spiritual ailments. Once you’re booked on one of our retreats, an information pack is sent to you to that effect. We also always present a practical understanding of the sacred teachings of these medicines, and how to work individually with each one of them.


We carefully craft and combine master plants like San Pedro and Ayahuasca with Kambo and Bufo to enhance your journey.

All medicines offered on a retreat are of course optional and upon arrival, we can help you customise your own retreat, with at times the possibility to substitute some medicines for others. The choice is yours and is skillfully guided by our expert facilitators to support your own personal experience.

Glorious & Unique Venues

We select very carefully our retreat centers and venues to offer the best combination of modern comfort in idyllic settings, steeped in abundant nature; far from the madding crowd, and close to an International Airport.

Simple Fees

We keep our fee structure simple. Depending on the location, we offer either all-inclusive or split fees (retreat/board) to cover all aspects of your journey with us. To book your place on any of our retreats, a non-refundable/transferable deposit is required. The balance is to be paid 3 weeks prior to the start.

Cancellations and refunds are outlined in our Terms & Conditions.

Note that our retreats have a minimum of 6 participants with a maximum of 20 participants to guarantee quality attention is given to every single person.

Who we are —  The team

Your guide on the journey, Frédéric Cherri

By nature, I'm not very fond of labels or titles. However, if I had to describe my path I would say that I’m mostly a practitioner of the shamanic arts, a therapist with 30yrs of clinical practice and tutoring in the field of cranial osteopathy, specialising in trauma, immune disorders and perinatal issues. I've also trained extensively for the last 25 years in the shamanic arts, and dedicated much of my time to living and studying with indigenous communities in many parts of the world.

I’m finally an entrepreneur, a retreat leader, a program teacher, a ceremonialist, a shamanic practitioner, an entheogen integration specialist and a personal coach. Years of study and practice on the path of workshop facilitation, field research and clinical & therapeutic work have led me to believe we can heal anything.

I'm also aware of being a bit of an 'oddball' in the realm of ancestral medicines, as I've trained (and keep training) in a variety of medicines and within different traditions. A medicine man or woman is usually a one-medicine specialist and trains in one sole tradition. I have answered the specific calls from some of these remarkable medicines and travelled wide and far to different jungles and mountains to work and study with varied first-people communities on this planet.

I believe there is a need for people like me to help bridge, protect and disseminate to a western audience the extraordinary wisdom of the first nations who share these medicines. Shamanic work and one of its mysterious and exciting aspects, the realm of plant or earth medicine, brings many answers to the unresolved issues of modern medicine or psychology. I have dedicated my life to supporting others’ journeys, growth, and transformation and am delighted to answer any questions via Zoom or WhatsApp chat. Schedule a free call here.
