3 Day Kambo & Ayahuasca Retreats

Ayahuasca & Kambo Retreat The Netherlands

Once a Month I am organising Kambo/Ayahuasca Retreats together with Kelvin Welling. In this special collaboration we will combine a 1-day Kambo ceremony with a 2-days Ayahuasca ceremony. Kambo and Ayahuasca are very powerful healing medicines from the Amazon rainforest, both of which can bring about a life-changing experience. The price for this 3,5 -day retreat is € 910, – euro. You can register directly by completing the questionnaire. On this page you will find more information.

The healing power of Kambo and Ayahuasca

Kambo is a medicine that comes from frog secretion and will cleanse your physical and emotional body. For many indigenous cultures in the Amazon, this purgative, immunity- boosting medicine is very important. It does not only cleanse the body from toxins, bad bacteria and viruses, but it also helps tremendously to let go of old emotional baggage.

Benefits of doing Kambo before your Ayahuasca sessions?

It’s perfect to do Kambo before your Ayahuasca Ceremony for releasing toxics and cleansing your body.

  • Toxics are released from your body.
  • Release of stress that you take into the Retreat.
  • It can give your energy a boost (not always).
  • Cleansing your body.
  • You are more opened up for going into your Ayahuasca Ceremony. Not only just because of the Kambo. Also because of the emotional work that Kelvin is doing.
  • You will feel the difference immediately after your Kambo session
  • There is a better connection with the group.
  • You will feel more safe going into your Ayahuasca Ceremony.

About Ayahuasca

Ayahuasca is an ancient plant medicine for the soul that Shaman from the rainforest have been using for millennia. Ayahuasca makes it possible to create a deep inner journey that helps you get insights about life, by healing the past and letting go old pain, to get another perspective about life, to release stress, to get more self-love and much more.

Would you like to understand your feelings?

Do you want to free yourself from remnants of unprocessed and unhealthy feelings from the past? Would you like to connect to your intuition, cleanse yourself of negative energies?

Do you want to improve your mental and physical health?

Do you want to aid your body in a cleansing of the digestive system and the rest of the body, removing stored mucus, parasites, yeast overgrowth and other impurities that rob energy?

This combined Retreat with one day of Kambo and a two day Ayahuasca Ceremonies gives you the perfect opportunity to tackle emotions or problems deep in your subconsciousness and achieve fundamental changes in you emotional and physical health.

What to expect from Kambo?

“The cure for pain is in the pain.” – Rumi

Kambo - Maria Johanna

Kambo is composed of peptide substances that are analgesic and anti-inflammatory and improve the immune system by killing bad bacteria, viruses and parasites. Kambo is know to treat brain diseases such as Alzheimer’s and Parkinson’s, migraines, blood circulation problems, depression. It helps to heal eyesight, skin disease, fertility problems, AIDS, cancer, candida, hepatitis, herpes, and more. Kambo has the reputation to be the world’s best natural antibiotic, and builds up the immune system through the body’s production of antibodies.

The Kambo spirit works with your intention as well as what it feels is most needed in the moment, therefor every experience is unique. Upon entering your body, the spirit scans your body and answers the call of where help is needed most.

Kambo practicioners: Who am I?

My name is Kelvin Welling. I work with different plant medicines and do emotional work with people. Plant medicines has drastically changed my life. I immediately felt and urge to share this with others. I believe everyone has a deeper purpose.  Before coming there I first had to heal myself and remove blockages and limited believes. Then naturally my path went towards working with plant medicines and other healing work.

I am an experienced entheogenic guide who will lead you safely through your shamanic journey. I hold the space, provide a protective energy and cleanse the negative energies that come up.

Kambo is very special to me because I healed myself when I was in a deep depression. As Shaman came om my path who showed my how to work with Kambo. After all, I have cured my depression with Kambo by doing 7 Kambo sessions in 7 days in a row with success. The band between me and the Kambo spirit is very strong. This is just one example. Meanwhile I have helped many others with the Kambo healing work and that is the best thing in The World to me. I would love to hold space and to help you too with the Kambo sessions.

Why Kambo?

Usually Kambo is an intense treatment. The goal is to make you feel better and to cure complaints or to give you a liberation of blockages. You will notice the effect immediately after the session. Why would you do a Kambo session? And how does Kambo help?

  • Physical, emotional and spiritual cleansing
  • Get rid of resistance and blockages
  • Solve health problems
  • Effective & fast cleaning at the cell level
  • Help to think more positive
  • Build self-confidence
  • Activate inner strength
  • Purifying your blood
  • Get rid of stress
  • More peace in your mind
  • Removing fear
  • Break through patterns
  • Growth of confidence in life and yourself
  • Experience clarity in yourself
  • Brain diseases, such as Alzheimer’s, Parkinson’s
  • Migraine & headache
  • Problems with the blood circulation
  • Allergies
  • Skin diseases
  • Fertility problems
  • Stress
  • AIDS
  • Cancer
  • High blood pressure
  • Diabetes
  • Depression
  • Addiction
  • Chronic diseases
  • Candida
  • Cure hepatitis, herpes and more

How to take Kambo with safety and respect?

If you have never taken the medicine before, we will start with a test dose first to test for an allergic or adverse reaction. If after 1 hour, no negative reaction occurs, we will go ahead with the treatment.

We will help you to decide the placement of the marks and together we will decide the dosing which is right for you (this differs for men and women and takes into account the sensitivity of each person). We will also let you know when and how much water to drink, how to position your body, and other aspects that will make the experience more comfortable.

It is very important to us to ensure a high quality of Kambo. We make sure that the poison was collected with respect and that the frog did not have to suffer, which is unfortunately not uncommon these days. (When collected respectfully the frog is in no way harmed). We receive our Kambo sticks from the Northwest Amazon, collected exclusively by indigenous Matses who depend on this medicine to keep them healthy and help with their hunting.

Why would you do Kambo before Ayahuasca?

Johan Tuhlin from Sweden

I can’t put in to words how much this journey has helped me. It has been the most life changing, powerful, positive, transformative experience I have ever gone through. Maria and her team could not have been more welcoming, caring and supportive . I can’t thank them enough for their healing, comforting and guideance.

Helen Bevan from the UK

I know everything is a process and everything comes at the right moment. The plant called me on two previous occasions when I was in South America.

I’m glad, I could not attend these opportunities, since experiencing the Ayahuasca Ceremony with Maria Johanna and her team was wonderful! I feel deeply grateful. The atmosphere was amazing with the music, the scents and the candles. All beautiful, every detail was accurate for what I had to live, learn and feel.

Patricia Jiminez from Spain

I want to thank you all of you for being so lovely and especially you Maria. My heart is so grateful. I understand now that past is past and everything happened for a lesson. I also forgived myself for being so rude against myself during this years.

Cyrielle Goufier from France

These ladies made me feel safe. They took time to be in alignment with the personal needs and inner quests of the group. Their guidance was so supportive, loving and caring.

I wish for everyone to have a wonderful Kambo/Ayahuasca experience like that! I’m still integrating my insights, but when the insights and unfolding lead me to a new riping Lifetheme layer, I would definitely return to join the ceremonies of these 3 ladies and team!

Dewi Huibers from The Netherlands

Dear Maria, I can’t find the words to express how much the Kambo & Ayahuasca Ceremonies , the love, the warmth, the love and everything around it has meant for me. I feel so much. There has come so much peace. The have seen the sun has rising again and I have felt it. In, for sure, 15 years I haven’t felt like this. So tremendously much love and acceptance. So special. A new beginning. The sun has rised. Thank yo uso much.

Mirjam Knots from the Netherlands

The Kambo had the effect of a huge cleaning up on me. It brought a sense of peace, love and clarity and was good preparation for the Ayahuasca.

In addition, this time I could just as well jump into the credibility of my mind and hook into heavy themes such as guilt, betrayal, inadequacy, shame and punishment, in short everything inclusive. I am once more aware of how important the good guidance has been in this ceremonies. Thanks.

Kees van Oostenrijk from The Netherlands

A very beautiful day to all you champs and connected souls.The weeks after Ayahuasca I became a greater version of myself BIGTIME. My intentions are reality now. I am  superhealthy since Ayahuasca, i didn’t sport a lot before, I went to bed late, I was smoking, sometimes still drinking some alcohol. What now: I am going to bed almost every day before 11pm. I wake up around 6/7 am, I go running, swimming, sauna every morning. I quit smoking, I quit drinking any alcohol, I am VEGAN now, almost no sugar.

Thanks again all for this amazing experience EVERYONE
I wish you all the veryvery best and please create all your own perfect reality
