TL;DR

The four things you'd lose by not watching

4 items
1

Caitlin Thompson has facilitated over 2,700 Kambo journeys and is conducting the first prospective human study on its psychological effects, finding significant improvements in mood and mindfulness.

2

Kambo is not a psychedelic; it's a frog skin secretion containing 27+ peptide analogues that produce intense physical purging via superficial burns, lasting 20-30 minutes, with applications for autoimmunity, Lyme, trauma, and spiritual opening.

3

The greatest risk is hyponatremia from excessive water intake, easily prevented with electrolyte supplementation, not the venom itself; mismanaged ceremonies have led to deaths mainly from water intoxication.

4

Indigenous use is casual and utilitarian (hunting magic), not shamanic, contrasting with the neo-spiritual ritualization in the West; sustainability concerns are rising as demand grows.

Standard Kambo ceremony in modern Western setting

WhatApply frog skin secretion (Kambo) to superficial burns on upper arm or lower leg, sit with the experience for 20-30 minutes while physical symptoms and purging occur, accompanied by ritual and supervision.
WhenTypically in a group ceremony lasting 2-3 hours; the active phase is 20-30 minutes.
Dose3-5 small burns, pea-sized amount of dried secretion reconstituted with water; duration of effects 20-30 minutes.
For whomPeople with chronic illness, autoimmune, Lyme, trauma, or those seeking spiritual/personal development. Should be screened for contraindications (e.g., heart conditions, electrolyte disorders).
WhyTo induce a purgative, cleansing reaction that releases physical and emotional toxins, improves autoimmune conditions, infections, mental clarity, and spiritual alignment.
CaveatsMust have a trained practitioner, proper hydration with electrolytes, supervision to prevent fainting and aspiration. Not for those with severe hyponatremia risk.

Caitlin describes the protocol: after preparing the participant with a small amount of water, the practitioner uses a hot stick to create a series of small burn marks, scrapes off the top skin layer, and applies the reconstituted Kambo. Within 30 seconds to a minute, effects begin: heart races, flushing, tingling, swelling, mucus production, sometimes vomiting and diarrhea. The ordeal is short but intense. The ceremony includes intention setting, music, prayers, and a bucket. The practitioner monitors vital signs, encourages purging, and provides emotional support. Post-session, the person rests and integrates. Caitlin stresses informed consent about the physical effects to avoid panic.

Mechanism

Peptides enter via lymphatics, causing vasodilation, stimulation of opioid and vagal receptors, release of gastric juices, bile, and purging; antimicrobial peptides kill pathogens; the intense stress forces a parasympathetic response, training resilience.

Personal experience

Caitlin has served thousands of people using this method, with zero medical emergencies, by being conservative and attuned.

So when it is applied, it's applied through these transermal superficial burns um made on the skin. Usually the upper arm or the lower leg... and you apply this frog skin secretion... within about 30 seconds to a minute, there are dozens of peptide families just kind of flowing in through the lymphatic system... and the effects come on rapidly.

Also said
“Um, usually you're going to feel like your heart beating faster and harder. You might get a hot flushing sensation or vibrational tingling sensations, heart beating in your temples. Uh, mucus coming out of the eyes and nose. Um, shaking is normal. Sweating is normal.”— Detailed symptom list.
“So it's quite a physically intense uncomfortable experience for most people but it's short and sweet you know it's like 20 to 30 minutes of this really condensed experience”— Duration and intensity.

Kambo hydration safety protocol

WhatBefore and during ceremony, drink water with added sea salt or electrolytes; limit total fluid to prevent hyponatremia; monitor urine output and signs of water intoxication.
WhenImmediately before and during the Kambo session.
Dose1-2 liters of water with approximately 1/4 teaspoon sea salt, sipped over the hour before session, and small amounts during. No forced over-drinking.
For whomAll Kambo participants, especially those on low-salt diets, fasting, or after ayahuasca.
WhyHyponatremia (low sodium) from excessive water without electrolytes is the primary cause of Kambo-related deaths and injuries; salt maintains osmotic balance.
CaveatsPeople with kidney disease or severe electrolyte disorders require medical consultation; do not use plain water only.

Caitlin highlights that many practitioners tell people to drink as much water as possible to help purging, but this can lead to fatal brain swelling. She advocates for adding sea salt to all water, monitoring how much goes in vs. comes out, and watching for early signs like headache, confusion, vomiting. She emphasizes that it's 'the stupidest way to die' because it's entirely avoidable. This protocol alone could eliminate most adverse events.

Mechanism

Sodium prevents dilutional hyponatremia and cerebral edema; the purging and sweating deplete sodium, which must be replaced.

The biggest risk is hyponetriia. So it's like drinking too much water which is like the stupidest way to die. Um, and it's so avoidable and... just put sea salt in people's water.

Also said
“If people have other conditions that might put them at increased risk of, you know, malabsorption or electrolyte disturbance, just supplement electrolytes beforehand. Um it's not that complicated actually and then know to look for the signs and then treat them promptly if they come up.”— Actionable prevention.

Kambo practitioner training and safe practice

WhatUndergo comprehensive training, learn proper screening, dosing, supervision, and emergency response; avoid overcrowding, sharing buckets, and unsupervised participants.
WhenBefore offering Kambo to others.
DoseTraining program; duration unspecified.
For whomAspiring Kambo practitioners.
WhyLack of standardization leads to preventable injuries; a well-trained practitioner can maintain safety while being effective.
CaveatsNot just any certification is reliable; look for scientifically literate, balanced training like Caitlin's.

Caitlin's 'worst practitioner' scenario includes: no training, no screening, packing many people, letting them fall, sharing buckets, and not escorting to bathroom. She runs a training program to raise standards because the space is unregulated. She emphasizes that even though Kambo is safe, proper diligence is crucial.

Don't get any training. Assume that it's as easy as it looks. Um, don't screen people. Just trust the spirits only. That's all you need.

Also said
“luckily, it's quite easy to keep it very safe. There's just a handful of things that you need to be very diligent about. Um, but unfortunately, there's no standardization of training um or care in the space.”— Problem statement.

Kambo is not a classical psychedelic but still alters consciousness

Despite being grouped with psychedelics, Kambo contains no hallucinogenic compounds; it produces intense physical sensations and emotional release, which Caitlin describes as 'mind expansive in its own unique way.'

Why this matters: Challenges the common lumping of Kambo with psychedelics like ayahuasca or psilocybin, clarifying its distinct pharmacological and experiential profile.

Background

Mainstream media and many retreats market Kambo as a psychedelic or plant medicine, but indigenous use and peptide analysis show no typical serotonin receptor agonism.

Caitlin emphasizes that Kambo lacks classical psychedelic effects like visual or auditory hallucinations. Instead, it induces a short, intense ordeal of physical symptoms (racing heart, flushing, swelling, vomiting) that forces confrontation with discomfort. The experience can lead to emotional catharsis and a sense of rebirth, but it's not akin to a trip. This distinction is crucial for informed consent and managing expectations. She notes that many people assume it's psychedelic and are surprised by the purely physical ordeal. The mind-expansion comes from facing the pain and the subsequent integration, not from direct neurochemical receptor activation like with LSD. This reframes Kambo as a resilience training tool rather than a typical psychedelic.

Personal experience

Caitlin personally found it gave her 'healing momentum' and increased vitality, but she doesn't describe it as a trip.

Technically combo is not a hallucinogenic or psychedelic substance. um it doesn't produce any sort of effects like similar to a classical psychedelic. So that's actually a common misconception. Um however, I will say that it is mind expansive in its own unique way.

Also said
“It's so much fun. Facial swelling is also common. And I I say that because sometimes practitioners don't give people full informed consent and that can be really scary for people, but they're not having an allergic reaction.”— Highlights physical, non-psychedelic nature.

Traditional Amazonian Kambo use has no ceremony or shamanic ritual

In its original context, Kambo was used for hunting magic, not as a shamanic healing medicine with prayers or songs. People would apply it and sit on a log vomiting, with no facilitation.

Why this matters: Counters the common Western assumption that Kambo is an ancient shamanic practice; it reveals a more pragmatic origin.

Background

Many retreats wrap Kambo in a spiritual, ceremonial frame, but the indigenous groups like Matis and Marubo treat it as a utility: for increasing sensory acuity, endurance, and occasional illness.

Caitlin explains that indigenous people would apply Kambo and then go on multi-day jungle walks without much food or water, hunt better, and occasionally use it for ailments like snake bites or a dark energy called 'panea'. They did not have intention setting, sage, music, or escorts; you were largely on your own, sometimes with a child holding you if about to faint. This contrasts sharply with the elaborate rituals in the modern West, which she sees as a neospiritual adaptation that is beneficial for Western seekers. The lack of traditional ceremony also means there's no ancient lineage of shamanic guarding or protecting, making the practice more 'technical' now.

Personal experience

Caitlin never brings people to the jungle who haven't done Kambo in a ceremony because she fears they'd be traumatized by the casual indigenous approach.

There's no sage. There's no intention setting. There's no escorting you to the bathroom. There's not even a bathroom most of the time. Um, there's no songs. Like there's >> there's nothing. It's a medicine, not a capital M medicine. You are just on your own.

Also said
“And occasionally like you know a a mat's child might come over and like hold you if they if you look like you're about to pass out, but you're largely on your own.”— Shows minimal intervention.
“It's very much just like taking an aspirin. You do it and then you move on with your day and um, not a lot of fluff.”— Reinforces the casual nature.

Ayahuasca's low-salt diet weakens the body and increases Kambo hyponatremia risk

Dave and Caitlin argue that the traditional ayahuasca diet (no salt, plant-based) is designed to make you weak so the medicine takes hold, but this depletes neurotransmitters and electrolytes, raising the danger of hyponatremia when combined with Kambo.

Why this matters: Challenges a fundamental retreat practice, warning that stacking medicines on depleted bodies is the cause of half the serious incidents; advocates for salt intake and electrolyte replenishment.

Background

Many ayahuasca retreats enforce a strict 'dieta' avoiding salt, sugar, spices, etc., to 'purify' the body. Practitioners often add Kambo as a bonus, leading to severe electrolyte imbalances.

Caitlin states that about half the hyponatremia cases occur when people do Kambo between ayahuasca ceremonies while already depleted from fasting and no-salt diets. Ayahuasca itself causes purging and neural activity that burns through ions. The no-salt diet prevents production of monoamine neurotransmitters, potentially making the ayahuasca experience less intense and smoother, but at the cost of resilience. Dave adds that shamans want you weak so the plant spirit can take over. Both recommend consuming sea salt and electrolytes before and during Kambo sessions, and avoiding the dogma of salt-free pre-ceremony. This is a direct safety intervention.

Personal experience

Dave says he always has salt before ayahuasca because he likes his brain to work and avoids low blood pressure.

Low salt diets are dangerous and the reason I've talked with shamanas about this. The reason they have you on low sal diet is to make you weak so the iawaska can take hold more.

Also said
“you know you're on a no salt dieta preparing for your iawaska ceremonies. You're purging all night. you have all this neurotransmission which is you know burning up ions and and changing gradients and uh then you do combo like in between your iawaska ceremonies as a bonus add-on and uh that's when probably half the cases of hyponetriia are people mixing things when they're depleted they've been fasting they've been on these anti- salt diets so just eat salt it's really easy”— Caitlin explains the dangerous combo.

First prospective human study on Kambo confirms mood and mindfulness gains

Caitlin completed a prospective psychometric study showing statistically significant improvements in mood, mindfulness, happiness, and reductions in pain and fatigue, but journals refuse to publish it due to stigma.

Why this matters: Adds scientific credibility to Kambo's therapeutic potential while exposing the bias in scientific publishing against non-mainstream substances.

Background

Almost all Kambo research is on isolated peptides in animals, with only two prior human studies: one survey and one from Caitlin's dataset, published in toxicology journals where benefits had to be downplayed.

Caitlin's study used validated scales pre- and post-Kambo. The results were so positive that she couldn't force it into toxicology journals where benefit statements are taboo. She finds the hostility from journals unscientific and frustrating, especially given the lack of institutional funding. A crypto millionaire funded this study with no strings. The difficulty in publishing highlights the drug development pipeline's bias against multi-component natural substances. This study is currently being submitted and she hopes to present it at the Wonderland conference. It represents a major step in legitimizing Kambo beyond anecdote.

We looked at you know pre and post combo and gave people all these scales to evaluate like mood, mindfulness, pain, fatigue, life satisfaction and there were really profound statistically significant improvements in mood and mindfulness happiness.

Also said
“So we didn't feel like putting that in a toxicology journal was really appropriate. We're like, no, like all, you know, all the other papers we have to kind of like beat around the bush and and not imply at all that there's any benefit to combo to get it published. But this, it's like, well, the data shows that there's benefit. So, how do we deny that?”— Highlights publication bias.
