What is Ayahuasca?

At a Glance

A warm welcome to SoulLiana. If you've heard the name Ayahuasca and want an honest, jargon-free starting point, this page is for you. In the simplest terms, ayahuasca is a sacred Amazonian medicine — both a vine (Banisteriopsis caapi) and the brew made by boiling that vine together with a leaf that contains the visionary compound DMT, usually chacruna (Psychotria viridis). Neither plant would work this way alone: the vine carries compounds that switch off the enzyme which would normally destroy DMT in the gut, so the brew becomes orally active — a pairing Amazonian peoples arrived at long before the chemistry was understood (McKenna et al., 1984). It is used for healing, divination and spiritual training, traditionally in a night-long ceremony guided by an experienced healer. It is not a recreational drug, not a guaranteed cure, and not safe for everyone — it carries real risks, particularly with certain medications. This guide written from the perspective of a student of the tradition, not a doctor or shaman, walks you through what it is, where it comes from, what a ceremony involves, what the research does and doesn't show, and how to stay safe.

This site is a living archive dedicated to the master plants of the Amazon, the experiences they offer, and the discipline of the dieta tradition. It is written from the perspective of a student, not a shaman, doctor, or certified therapist. The language of this tradition can be unfamiliar, so if you meet a term you don't recognise, you'll find it in our Glossary.

What Is Ayahuasca? (The simplest explanation)

The word Ayahuasca comes from Quechua: aya — "soul," "spirit," or "the dead" — and waska — "vine" or "rope." It is usually translated "vine of the soul," though "vine of the dead" is equally faithful to the word (Luna, 1986). The name points to two things at once: the Banisteriopsis caapi vine itself, and the sacred brew made from it.

That brew is a piece of remarkable Indigenous pharmacology. It is traditionally made by boiling the ayahuasca vine (Banisteriopsis caapi) together with the leaves of a companion plant that contains DMT — most often chacruna (Psychotria viridis).

Here is the key. DMT taken by mouth is normally destroyed in the gut by an enzyme called monoamine oxidase before it can have any effect. The ayahuasca vine contains β-carboline alkaloids (harmine, harmaline and tetrahydroharmine) that temporarily inhibit that enzyme — they are natural MAO inhibitors — which allows the DMT to become orally active (McKenna et al., 1984; Riba et al., 2003). This synergy, one plant unlocking the other, is the chemical heart of ayahuasca, and it was discovered through millennia of Amazonian plant knowledge.

While the visions are often associated with the DMT in the chacruna leaf, in the traditions we follow the Vine is considered the true teacher and the heart of the medicine. Naming the brew after the vine honours its role as the guiding spirit of the work.

To go deeper, see our pages on The Brew, the Banisteriopsis caapi vine, and its partner Chacruna.

Where Does It Come From?

Ayahuasca is not a new discovery. Its use is woven deep into the cultural and spiritual life of the western Amazon basin, and at least 72 Indigenous groups across several linguistic families are documented as having ayahuasca traditions, each with their own methods and understanding (Luna, 1986).

Among the best known are the Shipibo-Konibo of the Ucayali River region in Peru, for whom ayahuasca sits at the centre of an entire system of healing and cosmology. Their healers, the Onánya (or, in Spanish, curanderos), train for years or decades, including long periods of isolation and dieta, to learn their craft. The intricate geometric designs (kené) of their textiles are understood as visual expressions of the songs and energies perceived in ceremony, a codified visual language tied to the healing songs (Gebhart-Sayer, 1985; Brabec de Mori, 2013).

In 2008, in recognition of this ancestral knowledge, Peru's Instituto Nacional de Cultura officially declared the traditional knowledge and uses of ayahuasca Patrimonio Cultural de la Nación — Cultural Heritage of the Nation — protecting its place as a pillar of Indigenous identity and medicine (Instituto Nacional de Cultura, 2008).

What Happens in an Ayahuasca Ceremony?

An ayahuasca ceremony is a structured, sacred ritual. Every ceremony is different, but a newcomer can expect some common elements.

It is almost always held at night, in a quiet, dedicated space, and guided by an experienced healer — a curandero or curandera — whose role is to hold a safe, protected space, guide the energy of the room, and support each participant. After opening prayers and the setting of intentions, the brew is served. The effects, known as the mareación, typically begin within 30 to 60 minutes, build to a peak at around 1.5 to 2 hours, and the whole experience usually lasts about four hours (Riba et al., 2003).

The curandero's primary tools are the icaros — sacred songs received from the plant spirits during their training. These are not merely music; in the tradition they are the central instrument of healing, used to clean, guide and protect participants (Brabec de Mori, 2013).

A common and important part of the experience is La Purga, the purge. This often involves vomiting or diarrhoea, but can also take the form of shaking, crying, sweating or yawning. It is not regarded as a negative side effect but as a positive, healing act — a physical and energetic release of heavy, stagnant or accumulated material.

The experience itself can unfold across several dimensions: visionary (geometric patterns, symbolic imagery), emotional (buried feelings surfacing — grief, love, joy), and physical (changes in temperature, heightened bodily awareness). Difficult passages are common and are often where much of the work happens; a good facilitator is there to help you navigate them safely.

Why Do People Seek Ayahuasca — and What Does the Research Say?

People come to this medicine for many reasons. Some seek healing from deep-seated challenges — trauma, depression, addiction, grief. Others are on a spiritual path, looking for a deeper connection to themselves, to nature, or to the mystery of existence.

"It doesn't give you what you want — it gives you what you need."

This is a saying you'll hear again and again from maestros across the tradition, and it's worth carrying with you. People often arrive hoping to resolve one specific thing — a relationship, an addiction, a particular grief — and find that what surfaces is something else entirely, something they didn't know to ask for. Holding your intentions lightly, and trusting that what comes is what's needed, is part of the preparation.

Modern science has begun to study what Indigenous cultures have worked with for centuries, and the early findings are genuinely interesting — but they are early, and worth describing carefully. The most rigorous study to date is a randomised, placebo-controlled trial in 29 people with treatment-resistant depression, which found that a single dose of ayahuasca produced significant reductions in depression scores over the following week compared with placebo (Palhano-Fontes et al., 2019). A related analysis observed that levels of BDNF — a protein associated with brain plasticity — were higher after ayahuasca and correlated with lower depression scores, which is suggestive but is an association, not proof of a mechanism, and comes from small samples (de Almeida et al., 2019). On the question of psychiatric safety, a systematic review found that in controlled and ceremonial settings ayahuasca was generally not associated with lasting psychotic episodes, while cautioning that people with a personal or family history of psychosis remain a clear at-risk group (dos Santos et al., 2017).

It is crucial to keep a balanced perspective. Ayahuasca is not a magic bullet and not a guaranteed cure. No medical authority recognises it as a treatment. It is a powerful tool that can offer profound insight, but the slow work of healing and change ultimately rests with the individual.

What Is the Dieta Tradition?

As you explore this world you will meet the term Dieta. It's vital to understand that the formal Dieta is very different from the simple dietary restrictions one follows in the days before a ceremony.

The pre-ceremony diet is a short-term preparation — usually a week or two avoiding alcohol, pork, salt, sugar, spice and sexual activity — to cleanse and ready the body.

A Master Plant Dieta, by contrast, is a core spiritual discipline of the Amazonian tradition: a period of weeks or months in relative isolation, often in a simple jungle hut (a tambo), taking a specific teacher plant while keeping a highly restrictive diet (typically no salt, sugar, oil, spice or sexual contact) in order to develop the sensitivity needed to learn from the plant's spirit (Luna, 1984; Jauregui et al., 2011). This is the traditional method through which curanderos train — how they receive their knowledge, their healing capacity and their icaros directly from the plants.

To understand this foundational practice in depth, read our full page on The Dieta.

Is It Safe?

Ayahuasca affects body and mind in complex ways. While risk assessments have found that the brew itself has a low intrinsic physiological toxicity at the doses used ritually (Gable, 2007), this does not mean it is safe for everyone, and approaching it without genuine care is irresponsible. Most of the serious physical danger comes not from the brew alone but from interactions.

• Antidepressants (SSRIs, SNRIs, MAOIs): the most critical contraindication. Because the vine is itself an MAO inhibitor, combining ayahuasca with most antidepressants risks serotonin syndrome, a potentially life-threatening condition (Callaway & Grob, 1998). Coming off these medications safely requires medical supervision and time.
• Other medications and substances: a range of drugs can interact dangerously, including certain painkillers, stimulants and blood-pressure medicines; combining ayahuasca with alcohol or recreational drugs is hazardous.
• Pre-existing conditions: people with significant heart conditions, or a personal or family history of psychosis, schizophrenia or bipolar disorder, are generally advised not to drink ayahuasca (dos Santos et al., 2017).

Seen in proportion, serious adverse events are uncommon relative to the very large number of ceremonies held each year, but they are real and some have been fatal — most often where screening failed, a contraindicated medication was present, or the setting was unsafe (ICEERS, 2021). Thorough medical and psychiatric screening by a knowledgeable facilitator is not a suggestion; it is a necessity.

Is It Legal?

The legal status of ayahuasca is complex and varies sharply between countries. The crux is DMT, which is a controlled substance in most nations, including the United States, Canada, the UK and Australia. Because the brew contains DMT, it is technically caught by those laws even though the plants themselves are not always listed (ICEERS, 2021).

• Where it is protected: in Peru, traditional use is protected as cultural heritage (Instituto Nacional de Cultura, 2008). In Brazil, religious use is explicitly permitted and regulated by the national drug-policy council, CONAD (Resolução CONAD Nº 1, 2010). Official text (gov.br)
• Where it is a grey area: in the United States, specific religious organisations have won narrow exemptions — the União do Vegetal through the Supreme Court (Gonzales v. O Centro Espírita Beneficente União do Vegetal, 2006), and certain Santo Daime churches through later federal rulings. These are narrow religious exemptions, not general legalisation, and do not create a right for anyone to use or serve the brew. Full opinion (Justia)
• Where it is illegal: in many other countries the brew falls under DMT prohibition with no exemption.

It is your responsibility to understand the law where you are. For more detail, see the legal section of our Safety & Harm Reduction page.

Common Misconceptions

• Myth: Ayahuasca is a recreational drug. Reality: it is a demanding, often challenging experience treated by traditional cultures as a sacred medicine, not entertainment.
• Myth: Ayahuasca is a cure for mental illness. Reality: early research is promising but preliminary; no medical authority recognises it as a cure, and ethical facilitators frame it as a possible tool for growth, not a fix (Palhano-Fontes et al., 2019).
• Myth: It always brings life-changing visions. Reality: experiences vary enormously — some visionary, some emotional, some physical, some quiet. Nothing is guaranteed.
• Myth: The purge is just an unpleasant side effect. Reality: in the Amazonian tradition La Purga is a central and positive part of the healing — a deep physical and energetic cleansing.

Common Questions

What does the word "ayahuasca" mean?

It is Quechua: aya ("soul," "spirit" or "the dead") + huasca ("vine" or "rope") — "vine of the soul." The name refers both to the Banisteriopsis caapi vine and to the brew made from it.

Is ayahuasca addictive?

No. It has low abuse potential and is not habit-forming in the way of common drugs of dependence (Gable, 2007); it is taken periodically in ceremony, not compulsively, and the experience is demanding rather than rewarding in an addictive sense.

How long does an ayahuasca experience last?

Effects usually begin 30–60 minutes after drinking and last around 4–6 hours, with the most intense period in the first one to two hours (Riba et al., 2003).
