The Medicine within

A message from Frédéric Cherri  – SpiritRivers Founder

“The medicine you’ve been searching for lies within. Following the path with Ancestral Earth Medicines as your guides will help you unlock your connection to your own, unique inherent power. Through preparation and integration of a variety of ceremonies as well as shamanic processes, you can learn to apply ancient wisdom to your life in way that are respectful and conscious.

I can’t wait to help you discover or deepen the way to properly meet, how to keep you safe on your journeys. This particular retreat will help you return to long-forgotten Ancestral ways of cleasing and purifying.

You will find the ways to trust and surrender so you can manifest and thrive. You will also be shown how to release self-doubt, fear, disconnection and insecurity.

The rise of Earth Medicines allows us to enter a new era where the wisdom within is available to us all, now. Come join me for an experience and a journey into the depth of your being.
This is a deeply transforming retreat, where we will take a deep dive into the power of the heart, Soul Recovery being an important component to heal ourselves on a fundamental level and create harmony, joy and community in our lives —  Frédéric”

The Earth Medicines we will work with

San Pedro (Peruvian cactus)

Because it is a bit gentler than many of the other plant teachers, Huachuma has earned the nickname “The Grandfather” around the medicine community — Make no mistake though, San Pedro can produce as deep visions as any other entheogenic, Ayahuasca, Buffo Alvarius or Psilocybin mushrooms. However it is overall less intimidating, less jarring and more loving than many other plant teachers. — His main personality is two-fold: heart-opener...

Ayahuasca (Amazonian brew)

The Grandmother Ayahuasca is certainly to be respected as its strong spirit unfolds our minds and hearts to other realities and otherworldly experiences. It is a bright and convoluted teaching that will take you on a radiant journey. The teaching is also focused on the powers of the Intangible, it's residing spirits and the alliances we can make within those realms. The mission and personality of Ayahuasca is to educate and broaden our perception, to reform old limiting patterns, to ...

Bufo Alvarius (Mexican Toad)

Sapo (Bufo Alvarius) is the master of non-duality. It will show you what holds the cosmos. With practice it will also lead you to realise the mystical yet revealing link there is between the 'void' and it's purpose for our dayly-living. The experience of non-duality is counter-intuitively very practical as it allows us to live from the source, free from the hindrances of mundanity...

Kambo (Amazonian tree frog)

Kambocito, Kampu or Kambo has the propeties to reset your entire Immune system. It is very useful in our current times. It will also help you recode DNA. It works beautifully in preparation or as an adjuvent of other medicines. It's use is to be approached with respect, and trust in your Practitioner is paramount... We currently offer Kambo in almost all our retreats as it...

Rapé (Rapéh) Sacred Tobacco snuff

Rapé is a fine, light-colored powder containing tobacco and other medicinal and sacred plants, including tree bark ashes, leaves, seeds, and various herbs. Once collected, the components are pulverized with a pestle and filtered, The result is a fine powder blown into the nose.
Rapé brings you into a state of acute attention and awareness. The mind becomes calmer, negativity clears and emotional tensions are released. Participants often feel more grounded during the experience, allowing them to clear up confusions...

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 of 30yrs clinical practice and tutoring in the field of cranial osteopathy, specialised in trauma, immune disorders and perinatal issues. I've also trained extensively for the last 25 yrs in the shamanic arts and dedicated a lot of my time to live and study 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 ancestral medicines and with a variety of different traditions. A medicine man or woman usually is 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 of 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 it’s 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’ journey, growth and transformation and am delighted to answer any questions via Zoom or Whatsapp chat. Schedule a free call here.
