Every chronic illness has a deeper story.
Perhaps you've seen the specialists, changed your diet, taken the supplements — and the symptoms persist. Or perhaps you simply sense that your illness is trying to tell you something that no test result has explained.
Here is what conventional treatment often overlooks: unresolved emotional wounds and chronic stress can keep the body locked in a constant state of alert — the fight-or-flight response. A body in survival mode prioritises coping over repairing. Digestion weakens, sleep suffers, inflammation persists, and the immune system loses its balance.
This is why, in my experience as both a physician and a former chronic illness patient, every chronic condition deserves more than physical treatment alone. Lasting recovery often begins when we address what is driving that internal state — the trauma, the emotional patterns, and the life circumstances the body has been silently carrying.
When the nervous system finally experiences safety, two things change. The body recovers its natural capacity to repair itself. And you become able to make choices that support your health rather than undermine it — in your relationships, your work, and the way you live each day.
This is why we work at every level of your being — with knowledge, yes, but above all with care.
Dr Vanessa M Leon — Medical Doctor, Psychotherapist & Ayurvedic Practitioner.
Trained at Barts and The London School of Medicine · Formerly NHS · Licensed physician in Peru and Spain.
One method. Every level of healing.
Illness rarely lives at one level only.
Our approach addresses your health wherever the imbalance is held — physical, emotional, energetic, and deeper still.
The physical level — Ayurvedic integrative medicine
Our consultations are led by a Western-trained medical doctor and grounded in Ayurvedic holistic principles. Ayurveda allows us to understand each person as a whole — how physical symptoms, digestion, lifestyle, emotions and mental wellbeing interact. Through personalised plans that may include dietary guidance, lifestyle recommendations and Ayurvedic herbal medicines, we support recovery and long-term balance. We begin here because a depleted, inflamed body cannot do deep emotional work: first we strengthen digestion, sleep and physical resilience.
The emotional level — Relational Psychotherapy
My psychotherapeutic work brings together deep understanding and genuine care. Together we bring awareness to the beliefs, wounds and emotional patterns that may be keeping your nervous system in survival mode — this is an important part of the work, yet insight alone only reaches so far. Much of what we carry lives in the body, beneath words and logic, and can only be released by connecting to it.
So this is also somatic, body-centred work — held in a space where you feel safe, seen and supported. I walk alongside you in this, helping you reconnect with your own authentic self and power, so that what has long been carried can finally soften and be freed.
The energetic level — Intuitive energy work
Working intuitively, I support the body’s energy and the regulation of the nervous system through gentle, spiritually attuned practices that many people find deeply restful and reconnecting. It is a quiet, restorative layer that supports everything else we do, helping you feel more settled and more at home in yourself.
The deeper level — Ayahuasca vine (Banisteriopsis caapi) microdosing with preparation & integration
The Ayahuasca vine has long been regarded within Indigenous Amazonian traditions as a Master Teacher Plant that invites reflection, insight and reconnection with our true essence. In our 1:1 consultations and programmes, this work takes the form of microdosing with Banisteriopsis caapi — the vine on its own, which does not contain DMT, and whose natural alkaloids are beginning to be explored in emerging research — always with full preparation and integration. The traditional Ayahuasca ceremony is held within our retreats in Peru, where traditional Ayahuasca use is recognised as part of the country's cultural heritage, in a legal, cultural and carefully supported context. Throughout, we support you within an ethical, educational and supportive framework.
Note: We do not sell, supply or provide any illegal substances. Our work is educational and supportive, focusing on preparation, integration, personal growth and holistic health under voluntary basis.
And for those who feel called further, our programmes and retreats also make space for the spiritual, ancestral and cultural dimensions of healing — because some of what we carry did not begin with us.
Rooted in ancestral wisdom. Guided by modern medicine.
Dr Vanessa is of Andean Quechua heritage. Gnosis Clinic was born from a conviction that the traditional medical systems of the world — Ayurveda, and the Indigenous and shamanic medicine — carry wisdom that modern healthcare urgently needs, and deserve recognition, respect and revival.
This shapes everything we do: how we work with plants, how we hold our retreats in Peru, and how we understand healing itself. Because the wounds we carry are not only personal — they are also inherited. Family patterns, collective history and cultural trauma live in the body too, and true healing often means tending to these deeper roots.

This work is for you if…
You sense that your physical symptoms and your inner life are connected — and you're open to exploring that connection. You're not looking for a herbal substitute for a pill, but for genuine understanding of why your body is struggling and what it needs to recover.
You are ready to be met with love and honesty — and to be an active partner in your own healing. You want to be supported, and you are equally willing to take responsibility for your own transformation. This is gentle work, but it is not passive: it asks for your loving presence, so you can be held every step of the way with care.
If that describes you, you're in the right place.
People come to us navigating a wide range of chronic and stress-related challenges — often when standard care alone hasn't brought the relief or understanding they were hoping for. Many are experiencing:
-
Digestive disorders
-
Chronic fatigue syndrome and fibromyalgia
-
Anxiety, depression, panic attacks and ADHD
-
Stress and burnout
-
Somatic disorders
-
Insomnia, headaches and low libido
-
Skin conditions
-
Thyroid disorders
-
Somatic disorders
-
Autoimmune conditions
-
Women's health concerns
-
Metabolic health and weight concerns
Among others (contact us to discuss your specific case).
Ways to work with us
The Integrative Healing Programme — our core offering
An immersive, guided programme combining Ayurveda, relational psychotherapy, intuitive energy work and Ayahuasca-vine (B. caapi) preparation and integration — in an intimate group, with private 1:1 sessions with Dr Vanessa included.
This is the most complete way to experience our method: addressing your health at every level, at a sustainable pace, supported by a small community of others on the same path. Because healing was never meant to happen alone.
Places are limited and offered by application, beginning with a short call to ensure the programme is right for you.
Private Individual Consultations
For those who prefer fully individual work, or whose health situation calls for dedicated clinical attention, Dr Vanessa keeps a limited number of private consultation places. Many people begin here and later join a programme; others remain in 1:1 care throughout.
Initial consultation (online, 90 minutes) — £200 (€235 / US$260)
Includes a thorough medical and emotional health history, review of relevant medical tests, Ayurvedic assessment, a clear explanation of the possible physical, mental and emotional contributors to your condition, and a personalised treatment plan sent by email.
Ayurvedic medicines not included. Follow-ups (60 minutes, online) recommended every three-four weeks.
Holistic Retreat Programmes in Peru —traditional Amazonian medicine
Our retreats are never a single event. Each one is a complete programme — thoughtful preparation beforehand, an immersive in-person retreat— including traditional Ayahuasca ceremony — held within a legal and culturally respectful traditional context, and supportive integration afterwards — honouring the Indigenous traditions these practices come from.
Next retreat programme in Peru is in February 2027.
Gnosis
from the Greek γνῶσις
Gnosis Clinic was founded by Dr Vanessa León — Medical Doctor, Psychotherapist and Ayurvedic Practitioner. Born in Peru and of Andean Quechua heritage, she trained at Barts and The London School of Medicine, worked in the NHS, and is a licensed physician in Peru and Spain.
After being diagnosed with rheumatoid arthritis at 19, she went on to explore many dimensions of healing beyond conventional medicine — a path spanning nearly two decades that led her to recover her own health and, to study medicine herself. Her experience as both patient and physician has shaped an approach that honours the whole person — body, mind, heart and soul — and that is guided, above all, by love.
Gnosis — from the Greek γνῶσις, "knowledge": the wisdom that arises through direct experience rather than intellect alone. At Gnosis Clinic, we believe symptoms can become invitations to listen more deeply, restore balance, and understand what our lives may be asking of us.

As a former nutritional therapist I know what to eat and what to steer clear of. On top of that, I was followed by an excellent nutritionist for a good few years.
However, no matter how compliant I was with both following a rigorous food plan and taking a large amount of supplements, things weren't shifting enough. I tried for years. It only went so far.
Then, for some stroke of intuition I thought of giving the ancient practice of Ayurveda a shot. I searched and found the wonderful Vanessa, online.
Even with all the trust I had in her, I wasn't sure how she could manage to eradicate 5 years' history of obstinate bacterial infection when everything else had failed. Well, she did. In just a few months!
Also, my fatigue has lifted, my sleeping patterns are way better and my digestive system is on its way to recovery.
Ayurveda goes so much deeper than 'these foods are bad and those foods are good for you'. In fact, I have learned that there is no such thing as bad foods. There are foods that you as an individual may not be able to digest and that's why they are to be avoided until you recover.
That was revolutionary for me as my training has taught me the opposite.
Ayurveda is the epitome of a holistic system of medicine, where body and mind 'dance' together in perfect rhythm. You can't soothe one without restoring the other.
Vanessa's talent goes way beyond her knowledge in the field. There is a warmth, a gentleness and an unshakable commitment to her clients' recovery that is almost moving. I am forever thankful to her.

The best decision I’ve made for my health. A year ago I sought out Ayurveda, on a desperate search to feel better. I knew I was anxious, but didn’t know the whole of it. I also developed cubital tunnel syndrome from stress which resulted in my left hand being numb and weak to the point where I could no longer play musical instruments (or tie up my hair!) and was told I had to have surgery or I risked not getting the full mobility back.
I started with Ayurvedic treatment from Vanessa and very quickly felt a shift - more than anything I’d felt before (including after trying hypnotherapy).
I had an astrology session with Noel which was extremely insightful and accurate; it has removed a significant amount of doubt I’ve had about my feelings and convictions and given me a clearer sense of what flavour I bring to the world and how that feeds into my purpose here.
I then also started therapy sessions with Vanessa which has been pivotal in helping me uproot habits and beliefs that were holding me back. I love Vanessa’s balance of listening and guidance. Her presence is so open and comforting, I feel I can tell her anything.
I also received energy healing from Vanessa on my elbow which is now 99% recovered without any surgery and I am playing instruments again. My anxiety is gone, I still get stressed, but I know how to manage it now. It took me a while to properly commit to the lifestyle changes, but once I did I felt a massive shift. I feel like a whole person again who can live and enjoy life. This clinic had been a blessing in my life. I recommend Ayurveda to everyone now - if they know what ails them and especially if they don’t. Thank you Vanessa and Noel!
We are not just a clinic.
We are a community devoted to helping you flourish.
We welcome you with respect, love, and care. You are never just another patient to us, but a human being worthy of health, meaning, connection, and the opportunity to live in alignment with who you truly are.

"Working with Vanessa has been amazing. I came to see her with a range of issues that were impacting on my life and driving me a bit mad! Her recommendations and advice have made a huge difference to me. Finally, I now have a proper understanding of what my body and mind need to function properly. She has incredible knowledge and expertise as well as a genuine ability to really listen and care about your needs. Very grateful for her support."

"Through Vanessa’s guidance, I’ve seen a dramatic difference in my digestive health. I no longer bloat or suffer from pain post-eating and best of all, my body can now manage to digest gluten, after over 20 years of following a gluten-free diet, which is remarkable! The principles of Ayurveda are now with me for life, balanced with my Western culture. Thank you Vanessa, for your expertise, coaching and attention over the last 9 months".
Marta Machado,
Teacher
"Ayurveda with Vanessa has changed my life. It changed my life for the better, way better, every day. One way I can describe it is like being reborn again, as you learn to understand yourself - why you do certain things, in certain ways. It's been a beautiful journey, with challenges, which is a good sign, it means you're doing the work. Little by little, step by step towards a healthier version of me."
Devora Ivanova,
Yoga Teacher
I started virtual Ayurveda consultations with Vanessa which then led to doing an Astrology reading with Noel and now continuing my healing journey with psychotherapy sessions. My journey has been nothing short of transformational. Choosing Ayurveda in order to better understand why I was experiencing certain issues with my skin was my first step into my healing journey. It tackled my concerns from the root which is something I have been desperately seeking to do for years...
Vanessa and Noel both create the safest of environments where I am always listened to and cared for... Words are not enough to describe my gratitude to both Vanessa and Noel.
