The Epidavrian Longevity Reset

At the heart of the Epidaurian Longevity Reset is a simple yet profound intention: to create the space for the body, mind, and spirit to pause, restore, and deeply reset. Set within the sacred landscape and healing ley lines of the ancient Temple of Asclepius, this immersive experience invites participants into an environment where healing unfolds naturally—physically, emotionally, mentally, and spiritually.

More than a retreat, this is a once-in-a-lifetime healing and transformational experience that bridges the worlds of advanced medical science and profound spiritual practice. Rooted in the ancient wisdom of Epidaurus while embracing modern therapeutic approaches, the Epidaurian Longevity Reset offers a rare opportunity to experience healing in its fullest expression: cleansing the body, clarifying the mind, awakening the spirit, and reconnecting with the deeper purpose of life itself.

Participants leave not simply rested, but profoundly renewed—with greater clarity, a lighter and stronger body, practical tools for lifelong well-being, and a deeper connection to themselves and the world around them. This experience is designed to become a true turning point: an opening into a more aligned, energized, healthy, and awakened way of living.

Dr. Ioanna Gaka - Inuspheresis

Recreate Your Inner Landscape
Renew Your Body. Redesign Your Life.

Dr. Ioanna Gaka brings forth more than 20 years of experience in the medical field and is the director of the Inuspheresis clinic in Athens, Greece. She has helped hundreds of people through combining advanced medical purification therapies, conscious nutrition, and transformational practices.

Dr. Ioanna Gaka offers the opportunity for profound physical detoxification through Inuspheresis blood filtration therapy. This advanced treatment supports the removal of heavy metals, pathogens, parasites, pesticides, microplastics, and hundreds of other harmful substances that accumulate in the body over time. By reducing toxic load, the body is given the opportunity to restore clarity, improve energy, and support long-term health and vitality.

Ray Crist - Cultivating the integrated self

Ray has spent over twenty years traveling the world in search of authentic healing traditions and the masters who carry them. From Johns Hopkins and the NIH to the Jungles of Peru, inspired by the ancient healing lineage of the Temple of Asclepius in Epidaurus, he now offers transformative retreats in this sacred landscape.

Ray guides participants through transformative shamanic practices designed to release negative energetic patterns, reconnect with the inner world, and awaken deeper intuition. Through guided journeys and power animal work, participants will discover archetypes, spiritual allies, or symbols of guidance that inspire clarity, protection, and renewed purpose. These experiences are designed to cultivate inner strength, self-awareness, and a more empowered way of living.

Nina Crist – Tai Chi & Inner Balance

Through gentle flowing sequences, practitioners learn to release tension, improve circulation, and reconnect with their center. Nina guides students to feel rather than force, encouraging softness, presence, and responsiveness. In this space, balance is not something to achieve, but something to remember.

Nina Crist brings a lifetime of martial arts mastery into deeply restorative Qi Gong and Tai Chi practices that harmonize the organs, strengthen the body, and cultivate vital life force energy. Her teachings offer not only a powerful experience during the retreat, but also practical sequences participants can continue at home as lifelong tools for balance, resilience, and vitality.

Renewing the Body's Inner Rivers

The ancient Greeks believed that health begins with the purity of the body's internal flows.

Modern medicine now understands that the bloodstream is indeed the body’s central river of life.

One of the innovative therapies offered during this retreat is therapeutic blood purification, INUSpheresis treatment.

This Swiss medical process filters blood through a specialized system that removes more than 500 known pathogens, inflammatory substances, toxins, and harmful proteins, and more.

This process supports the body in restoring balance while enhancing circulation, cellular hydration, and overall vitality. By helping remove toxins from the bloodstream, it offers tremendous relief to the body, allowing it to release accumulated waste and impurities that it may not have been able to eliminate on its own.

In the context of this retreat, this therapy becomes part of a broader philosophy:

Creating a new river of life within the body. A river that no longer carries the patterns of the past.

Why the Epidavrian Longevity Reset?

Modern life overwhelms the nervous system and slowly drains the body of vitality.

Constant stimulation, processed food, environmental toxins, and emotional stress accumulate within our inner environment.

Over time this internal landscape begins to shape our health, our energy, and even our life direction.

The Epidavrian Longevity Reset was created to interrupt this pattern.

For seven days you step out of your normal life and enter a carefully designed environment where the body can reset, the mind can clear, and a new future can begin to take shape.

This is not simply a retreat.

It is a complete recalibration of your inner ecosystem.

The Philosophy: Your Inner Landscape

Every thought, emotion, and internal state shapes how we experience the world.

When our inner environment becomes cluttered—with stress, toxins, unresolved emotions, or mental noise—our outer life often reflects this imbalance.

At the Longevity Retreat, we focus on three layers of renewal:

Mental Clarity

Clearing the mind from constant stimulation and stress.

Emotional Release

Letting go of patterns and emotional residue that hold us back.

Physical Purification

Supporting the body’s natural ability to detoxify and regenerate.

When these three layers align, something remarkable happens:

Your entire life begins to reorganize around health, clarity, and purpose.

Cleansing the Inner Terrain

Alongside advanced medical treatments, we support the body through natural processes of renewal.

Participants experience a carefully guided transformation that may include:

Digestive Reset

Through gentle dietary changes and digestive support, we allow the intestines to release accumulated waste and restore balance to the gut.

This process often has profound effects not only physically but emotionally, as the gut and nervous system are deeply connected.

Hydration and Cellular Renewal

Guests drink natural spring water sourced from the mountains of Epidavros - water that is pure, mineral-rich, and deeply nourishing.

Hydration at the cellular level supports the body's ability to regenerate, transport nutrients, and release toxins.

Nutritional Recalibration

During the week, participants follow a carefully designed nutritional program that supports:

• detoxification
• cellular repair
• metabolic balance
• long-term vitality

The goal is not simply a temporary cleanse.

It is the beginning of a sustainable lifestyle transformation.

The Epidavrian Environment

Location matters.

Epidavros has long been known as a place of natural harmony, beauty, and healing. Surrounded by mountains, forests, and ancient landscapes, this environment becomes an active participant in the retreat. This is the home of the first hospital and retreat center built under the supervision of Ascepius himself.

Nature itself becomes medicine.

Guest's experience:

Mountain air and pure spring water
Restorative silence and natural beauty
Natural hot springs
Movement practices in nature
Deep cellular rest and reflection

This environment supports the nervous system in shifting from stress mode into healing mode.

Scientific Research on INUSpheresis

Dr. Beate Jaeger – Long-COVID and Post-Viral Syndromes

Dr. Beate Jaeger and colleagues have studied the use of therapeutic apheresis in patients suffering from Long-COVID and post-viral syndromes. Their research found that plasma filtration significantly reduced inflammatory markers, autoantibodies, and circulating lipids associated with vascular dysfunction. Many patients reported improvements in fatigue, cognitive clarity, and circulation-related symptoms, suggesting that removing pathological blood components may help restore microcirculation and immune balance.

Dr. Beate Jaeger and the INUS Medical Center – Observational Clinical Outcomes

At the INUS Medical Center in Germany, Dr. Jaeger and her team have documented outcomes from over 1,000 patients treated with INUSpheresis for chronic fatigue, inflammatory conditions, and metabolic dysfunction. Observational results indicate that many patients experience symptom relief after treatment, with a majority reporting noticeable improvements following multiple sessions. These findings suggest that targeted plasma filtration may help reduce inflammatory burden and metabolic stress.

Prof. Dr. Florian Kronenberg – Lipoprotein Apheresis and Cardiovascular Risk

Professor Florian Kronenberg and international cardiovascular research groups have extensively studied lipoprotein apheresis, a related filtration therapy widely used in cardiology. Their work demonstrates that the treatment can reduce lipoprotein(a) and LDL cholesterol by up to 60–75% in a single session. Long-term treatment has been associated with significant reductions in cardiovascular events in high-risk patients, establishing a strong scientific foundation for plasma filtration approaches aimed at improving vascular health.

Dr. Ralf Klingel – Removal of Inflammatory and Autoimmune Factors

Dr. Ralf Klingel and other experts in therapeutic apheresis have shown that plasma filtration techniques can remove inflammatory cytokines, immune complexes, oxidized lipids, and autoantibodies from the bloodstream. These findings support the concept that therapeutic apheresis may help reduce systemic inflammation and improve blood rheology, potentially benefiting patients with chronic inflammatory and immune-mediated conditions.

European Integrative Medicine Research – Metabolic and Inflammatory Markers

Recent European research examining modern apheresis systems has documented reductions in oxidized LDL, triglycerides, inflammatory markers, and blood viscosity following treatment. Improvements in endothelial function and circulation have also been observed. These findings suggest that advanced plasma filtration therapies may support metabolic health and help address chronic inflammatory load.

My experience with INUS

In 2003, I was diagnosed with terminal cancer and given three months to live. Hoping for a more favorable diagnosis—or a treatment plan involving surgery or medicine that could lead to healing—I traveled to the United States and sought help from some of the world’s leading medical institutions, including Johns Hopkins Medicine and the National Institutes of Health. From the leading medical centers to the jungles of Peru, I have found this to be the most profound healing tool and deepest spiritual experience!

Click to hide text

Coming out of my visit to Johns Hopkins, the diagnosis remained the same.
When I asked, “Is there anything I can do?” the answer I received was:
“Take care of your affairs.”

In response to those words, I began a journey through Mexico and Peru in search of healers, wisdom, and hope.

In January 2006, I underwent surgery at the NIH in hopes of extending my life by a few more months. But I did not stop there. I had a two-year-old son waiting for me back home in Greece, and I made the decision to continue searching—to travel deeper into the Amazon jungle and work with indigenous tribes and healers.

So I did.

Today, I am still alive. And each year, my now 24-year-old son and I travel together to different parts of the world to learn from cultures, explore life, and experience the beauty of this planet together.

Through this journey, I have come to a very clear conclusion:

Use every tool available to you.

Western medicine. Eastern medicine. Conventional and alternative healing methods. Yoga and Tai Chi. Proper nutrition. Detoxification. Practices that bring balance to the body, mind, and spirit.

After more than 20 years of researching health, healing, and human potential—and after working with hundreds of people, exploring countless fasting and detoxification methods—I discovered a blood filtration technology from Switzerland unlike anything I had encountered before.

Similar to dialysis, this advanced filtration process removes more than 500 known toxins and pathogens from the blood, including heavy metals, microplastics, parasites, pesticides, and many other harmful substances.

In all my years of exploring healing and spiritual evolution, I can say with confidence that the experience I had immediately after my first INUS blood filtration treatment was one of the most profound physical, intellectual, and spiritual upgrades I have ever experienced.

I am deeply grateful to Dr. Ioana Gaka, director of the INUS clinic in Athens, for sharing this work with me and guiding me through such profound healing. She embodies a rare and beautiful combination of scientist and mystic. What I deeply respect about her approach is that she is classically trained in Western medicine and uses advanced technology to support healing, while at the same time carrying a profound spirituality that is felt the moment you enter her clinic.

As a result of my lifelong exploration into healing, consciousness, and human optimization, I chose to live in the sacred healing land of Epidaurus, directly across from the ancient healing temple of Asclepius at Epidaurus—the birthplace of holistic healing and the sanctuary associated with the lineage of Hippocrates.

With all of this in my heart, I am now offering a retreat centered around the tools, practices, and methods that I believe have been most essential to my own healing, vitality, and spiritual growth.

If you are navigating health challenges—or simply feel called to move into the next level of your physical, emotional, and spiritual evolution—I invite you to join us for this week-long Longevity Reset.

This is more than a yoga retreat.
More than a Tai Chi retreat.
More than a healthy food immersion.

It is a complete reset of the body, mind, and spirit—a powerful opportunity to cleanse, realign, and awaken.

And from my personal experience, I can honestly say: the transformation possible in one week may surpass what many people experience after years of searching.
