Who is Katharsis?

The project was started by a team of medical doctors and a neuroscientist, who alongside traditional healers make up a holistic team bridging the latest scream in science with ancient wisdom and practices.

We are striving toward establishing a friendly dialogue between academic science and spirituality,  paying respect to traditional methods of working with entheogens. This is why we have chosen to include representatives from both of these worlds in our team


"What a beautiful and valuable experience. The way in which the Katharsis team genuinely combines modern scientific knowledge with the age-old traditions of the use of plant medicines is particularly strong. The broad and personal approach is also reflected in the team of doctors, musicians, assistants and the shaman. In addition to professionals, very pure people who, with their experience and skills, know how to create a safe environment in which every person is given the space to grow. The structure of ceremonies, conversations and activities was perfect. I'm very impressed."


"Thank you for helping me to understand better and to accept myself for being me. The love and kindness that you offer with your approach to psychiatric "care" vs "treatment" is paramount to connect with the patients who truly need it the most."


"The experience of Katharsis Journeys is something that brought me years worth of therapy in terms of healing and growth, as well as an environment that was warm and authentic, yet professional. The teams of traditional healers and medical doctors worked in unison, showing a beautiful display of what it means to connect our past and our future. After just 5 days, I had the equivalent of a month's rest and I returned more equipped to deal with the challenges of my work. "


"The tranquil setting of the retreat center combined with the nutritional counseling, breathwork, one-to-one sessions with facilitators, live music, and the truffle ceremonies makes Katharsis Journeys, without a doubt, one of the best psilocybin retreats in Europe. "
