Finding a Kambo practitioner: what to check

BySafe Ceremonies

A search for “kambo ceremony near me” usually brings up wellness practitioners, weekend workshops and retreats that offer it as an extra. Their pages tend to talk about cleansing and rarely mention what they would do if you fainted. Almost anyone can offer a session, so choosing a practitioner carefully is one of the few real protections you have.

This guide covers how to check a practitioner before you agree. If you’re new to Kambo, start with What Kambo is and What to expect at a Kambo session, which explain the frog, the session and the medical reports. We won’t repeat them here. This guide doesn’t cover how to get or apply Kambo, and it isn’t medical advice. For what the law says in different places, see the note on the law in our Kambo guide and our overview of plant medicine laws around the world.

What a certificate does and doesn’t tell you

We found no public body that licenses Kambo practitioners, and nobody knows how many there are. A 2025 systematic review in Cureus names that as one of the problems in judging the risk. It also says adverse effects seem particularly common where non-traditional practitioners operate, though it gives no figures. Chacruna, a research and education institute, describes courses that train “urban applicators” and websites in Europe that sell the substance.

In a 2021 survey of 386 Kambo users, published in the Journal of Psychopharmacology, about three in four said the person who applied it was a Western shaman, healer or natural health professional. About 13% said it was an Indigenous practitioner, and about 7% said it was someone with no special training.

So a certificate shows that someone attended a course run by somebody else. It doesn’t tell you what they would do in an emergency. Ask:

  • Who trained you, for how long, and how many sessions did you run under supervision?
  • How many sessions have you given, and how many went wrong? What happened?
  • Do you hold a current first aid and CPR certificate? May I see it?
  • Have you ever called an ambulance for a client, or decided not to?

“I’ve never had a problem” isn’t a reassuring answer from someone who has given hundreds of sessions. It may mean they haven’t recognized one. Our guide to facilitators’ experience and training goes further.

Check the screening before you check anything else

The 2025 review calls screening for existing medical conditions critical to safety, and recommends rigorous protocols. Our Kambo guide lists the conditions and medicines to expect questions about. Here, the thing to judge is how the practitioner handles them.

A careful practitioner does these things:

  • Sends you a health questionnaire before taking money you can’t get back.
  • Talks through your answers with you, and asks about anything you left vague.
  • Asks about every medicine and supplement, and suggests you check them with your doctor or a pharmacist.
  • Asks whether you’ve had ayahuasca or anything else recently, and whether more is planned.
  • Asks about pregnancy. The review advises pregnant women to avoid Kambo.
  • Has turned people away, and can tell you what for.

A practitioner who says Kambo is safe for everyone, or who would decide on the day by how your energy feels, has told you they aren’t screening. Be wary of any offer that adds Kambo during a retreat without a separate conversation about your health. In the 2021 survey, about one in ten sessions took place during an ayahuasca or other psychedelic ceremony.

Ask about water, and listen closely

This one question may tell you the most about a practitioner. Water comes up again and again in the case reports:

  • A 2022 review of 11 poisoning cases found three in which people drank several liters of water.
  • In a 2025 case report, a 35-year-old woman drank large volumes before a ritual as part of the facilitator’s routine. Her sodium fell, her brain swelled, and she was declared brain dead.
  • In another 2025 report, a 64-year-old woman drank about a gallon, became unresponsive and spent time in intensive care. She recovered.

The authors of the second report note that excess water comes up more often with non-native practitioners and modern versions of the ritual, and they warn that Kambo itself may also disturb the hormone that controls the body’s water balance. So cutting back on water may not remove the risk. We can’t give you a safe amount, and we didn’t find a published one.

Ask how much they’ll ask you to drink, and over what time. Then ask why. You’re looking for someone who knows about low blood sodium, can name its signs and treats water as a risk they manage. Answers such as “as much as you can,” or “drink more if you feel bad,” are reasons to leave. So is being told that a pounding headache or confusion is the medicine working.

The room, and who else is in it

In the 2021 survey, 63% of sessions were in a group, and about one in four took place in a friend’s home or other private space. The same people reported these effects:

  • Vomiting, 87%.
  • A racing heart, 67%.
  • Facial swelling, 55%.
  • Anxiety or panic, 17%.
  • Loss of consciousness, 12%.

That survey recruited through Kambo websites and practitioners, so its sample is skewed. It still gives you a sense of what a practitioner has to be ready for. If one person in eight may pass out, someone has to be close enough to catch them. There’s no agreed staffing ratio for Kambo. Ask how many people will be in the session and how many helpers, and what happens if two people faint at once. If you’d be sitting on a hard floor, on your own, with the practitioner across the room, ask them to explain how they would reach you in time.

Ask too how long they stay. Effects from a session pass fairly quickly, but in the 2022 review, symptoms started up to 12 hours afterwards, and in both 2025 cases, serious symptoms appeared hours later. A session where you’re sent home alone after an hour leaves nobody watching during that window. Line up someone to stay with you that night who knows what to look for. Our session guide lists the signs.

Emergency plan

The 2025 review criticizes the lack of adequate medical supervision during Kambo sessions, and the 2022 review reports that all but one of its 11 people recovered once treatment started. It helps if treatment comes fast and doctors know what they’re dealing with. Ask:

  • At what point do you call an ambulance, and who makes the call?
  • Exactly where is the session, and how long would help take to get there?
  • Would you tell paramedics and the hospital that this was Kambo and how much water was involved?
  • Who has my emergency contact?

Our guide to emergency plans gives you a full list to hold them to. A practitioner who is reluctant to call for help, for whatever reason, isn’t someone to trust with your heart rate.

Where the secretion comes from

The 2025 review warns that inexperienced practitioners may use secretions from other species, such as the cane toad. Ask what they use, where it comes from and how they know. You won’t be able to verify the answer, but you can tell whether they’ve thought about it.

There is another side to the question. A 2021 article published by Chacruna says little is known about the current ecology of the giant monkey frog, and that nobody has measured how growing demand affects it. It reports that the Indigenous Noke Koĩ people asked for protection of their knowledge in 2003, and it asks what participation and return Indigenous people get from today’s trade. Ask whether any of what you pay goes back to the communities this comes from. Few practitioners will have a full answer, and an honest “I don’t know” is better than a story. Our guide to reciprocity and sustainability has more.

Red flags

  • Promises that it will cure an illness, clear toxins or replace your medicine. The 2022 review found no clinical evidence for these claims.
  • Pressure to book a set of sessions before you’ve had one.
  • Offers to sell you Kambo to apply yourself. The 2025 review singles out unregulated online sales as a concern.
  • No questions about your health, or a form nobody discusses.
  • Telling you to stop a prescribed medicine, without your prescriber being involved.
  • Calling chest pain, fainting or confusion “part of the purge.”
  • Refusing to say where you’d be, or who else would be there.

Our general guide to red flags covers more. A practitioner who is slow to book you, or who turns you down, is usually showing you the care you were looking for.

Keep the risk in proportion

Most people who answered the 2021 survey didn’t report lasting harm: 2.85% described long-lasting physical problems they put down to Kambo and 1.81% mental or emotional ones. The authors note that their recruiting probably favored positive accounts, and there was no control group. The case reports show the opposite end, and they can’t tell you how often things go wrong either. Nobody has good numbers. That is why your questions matter more than any statistic.

A short plan

  1. Read what Kambo is and check your health and medicines with your doctor.
  2. Search the listings near you and read reviews for how the practitioner screened people and responded when someone reacted badly.
  3. Email your questions, so you have the answers in writing. Our list of questions to ask before you book adds more.
  4. Rule out anyone who is vague about water, screening or calling for help.
  5. Arrange for someone to be with you for the rest of the day and that night.
