About Us
Gnosis Clinic (formerly The Ayurvedic Practice) was founded by Dr Vanessa Leon, a Medical Doctor, Psychotherapist, and Ayurvedic Practitioner. Born in Peru and of Andean Quechua heritage, she created a sanctuary where modern science and traditional healing wisdom meet in a compassionate, heart-centred way. After being diagnosed with Rheumatoid Arthritis at the age of 19, she embarked on a lifelong journey exploring the many dimensions of healing and wellbeing. Over the past 15 years, her experience as both physician and patient has inspired her to explore approaches that honour the whole person — body, mind, heart, and soul. Today, Gnosis Clinic offers an integrative approach that brings together modern and ancient perspectives, drawing on Ayurveda, psychotherapy, indigenous medicine, and other holistic and integrative medicine practices tailored to each individual’s unique journey.

We don't just focus on your symptoms.
We aim to heal your life and support you in finding your purpose and soul path.
It's our disconnection from our true nature that often makes us fall ill.
When we push our bodies to live a life they weren't designed for, they speak back to us through symptoms and illness.
We aim to restore balance to your body, mind, and heart so your whole being can flourish.
Healing involves more than symptom management.
You may be ready to:
-
Improve your health and support your body's capacity to heal.
-
Understand the deeper meaning behind persistent symptoms.
-
Transform the fears and patterns that may be preventing you from living fully.
-
Cultivate a more compassionate relationship with yourself.
-
Deepen the connection between your body, mind and soul.
-
Live a healthier, more meaningful and authentic life.
Health often begins with a new relationship with yourself and
at times, an entirely new way of seeing life.
Gnosis
from the Greek γνῶσις
Derived from the Greek word for "knowledge", Gnosis refers to the wisdom that arises through direct experience rather than intellectual understanding alone.
At Gnosis Clinic, we believe healing involves reconnecting with the innate intelligence of the body, mind, heart, and soul. Symptoms can become invitations to listen more deeply, restore balance, and understand what our lives may be asking of us.
Our aim is to support people not only in improving their health and wellbeing, but also in remembering who they truly are and living in greater alignment with their authentic nature.
How We Support Your Healing
Ayurveda Integrative Medicine
Our medical consultations are grounded in Ayurvedic holistic principles. Ayurveda allows us to understand each person as a whole, exploring how physical symptoms, lifestyle, emotions, and mental wellbeing interact. Through personalised treatment plans that may include dietary guidance, lifestyle recommendations, and Ayurvedic herbal medicines, we aim to support recovery, restore balance, and help you maintain long-term health.
Psychotherapy
Psychotherapy offers a space to explore the emotional experiences, beliefs, and patterns that may influence both physical and psychological wellbeing. Through this process, we aim to foster greater self-understanding, resilience, and the capacity for meaningful change.
Ayahuasca microdosing integration (Banisteriopsis caapi only)
The Ayahuasca vine has long been regarded within indigenous traditions as a Master Sacred Teacher Plant that invites reflection, insight, and reconnection with our true essence. While it is the principal ingredient of the traditional Ayahuasca brew, Banisteriopsis caapi on its own does not contain DMT. Emerging research has begun exploring the properties of its natural alkaloids. We support individuals in preparing for and integrating the insights that may arise through their relationship with this tradition within an ethical and therapeutic framework.
Note: We do not sell, supply, or provide any illegal substances. Our work is educational and therapeutic, focusing on integration, personal growth, and holistic health.
Psychological Astrology
Provides a symbolic map of your inner world, illuminating strengths, challenges, relational patterns, and developmental themes. Rather than predicting the future, it offers insight and perspective that can support self-understanding, personal growth, and alignment with your deeper values.
Legal shamanic healing retreats in Peru
Our retreats are held within a legal and culturally respectful context, offering participants the opportunity to engage with indigenous traditions through preparation, therapeutic support, and integration. These experiences provide an opportunity for profound reflection, connection, and personal transformation within an environment grounded in safety, care, and community.

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!

"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.
