This page introduces Ayahuasca for readers with no prior background. Where a term is specific to Amazonian tradition, it is explained in passing. For a fuller reference, see the Glossary.


What is Ayahuasca?

Ayahuasca is a medicinal brew made from two plants found in the Amazon rainforest. It has been used for centuries — possibly millennia — by indigenous peoples of the Amazon as a tool for healing, spiritual insight, and communication with the natural world.

The name comes from Quechua: aya (spirit, soul, or the dead) and huasca (vine, rope, or cord). It translates roughly as “vine of the soul.”

The brew combines two plants that work together to produce its effect:

  • The VineBanisteriopsis caapi, the Ayahuasca vine itself. It contains beta-carboline alkaloids (harmine, harmaline, and tetrahydroharmine) that act as MAO inhibitors, temporarily blocking an enzyme in the gut that would otherwise break down the second ingredient.
  • The Leaf — typically Psychotria viridis (Chacruna). It contains DMT (dimethyltryptamine), which produces the visionary component of the experience. Without the vine, DMT is destroyed by the gut before it can reach the brain.

Neither plant produces the full effect alone. Together, they create an experience that indigenous peoples have used as medicine for generations. How ancient cultures discovered this combination — out of tens of thousands of plant species in the Amazon — is one of ethnobotany’s open questions. The traditional answer is that the plants told them.

Where Does It Come From?

Ayahuasca comes from the indigenous traditions of the western Amazon basin — primarily Peru, Ecuador, Colombia, and Brazil. The traditions most associated with its ceremonial use include the Shipibo-Konibo, the Asháninka, and various mestizo curandero (healer) lineages, though its use spans over 100 indigenous groups across the Amazon.

The brew is prepared by a curandero or curandera (healer); in the Shipibo tradition this person is also called Onanya. Preparation is itself part of the ceremony: the vine is pounded and cooked with the leaves over many hours, often with prayers, songs, and intention. In the tradition, the healer’s relationship with the plants is held to matter as much as the ingredients.

For more on how the brew is made, see The Brew.

What Happens in Ceremony?

An Ayahuasca ceremony typically takes place at night, in a ceremonial space — often a maloca (a large, open-sided wooden structure) in the jungle. Participants sit or lie on mattresses. The space is usually dark, or lit only by candles.

The curandero opens the ceremony with prayers and the blowing of Mapacho (sacred tobacco) smoke to cleanse the space. Each participant drinks a small cup of the brew, and then waits.

The Onset

After 30–60 minutes, the effects begin. You may feel nausea, heaviness in the body, changes in temperature, or a sense that the room is shifting. Your normal sense of control over your body and thoughts starts to loosen. This can be disorienting and, for some, frightening, but is part of the onset.

La Purga

Vomiting is a central part of the Ayahuasca experience. In the tradition, it is called la purga — the purge. It is considered part of the healing rather than a side effect: physically expelling toxins, and energetically releasing grief, anger, fear, or other accumulated emotional weight. Not everyone purges every time, and it can also manifest as crying, sweating, or diarrhoea.

It is unpleasant. There is no way around that. Many people describe the purge as one of the most liberating parts of the experience.

The Experience

Throughout the ceremony, the curandero sings icaros — sacred healing songs that are the primary instrument of the healer’s work. These songs are received directly from plant spirits over years of apprenticeship rather than composed by the singer. They guide the energy of the ceremony and the individual experiences of each participant.

What happens during the experience varies widely between people and between ceremonies:

  • Visual: Some people see vivid geometric patterns, landscapes, beings, or symbolic imagery. Others see very little.
  • Emotional: Buried feelings often surface — grief, love, fear, joy. This can be overwhelming. It can also be where much of the healing happens.
  • Physical: Sensations of energy moving through the body, temperature changes, trembling, or stillness.
  • Cognitive: Insights about your life, relationships, patterns, and purpose. A sense of seeing clearly what was previously hidden.

The experience typically lasts 4–6 hours. It is not recreational or pleasant in the way that word is normally used. It is a medicine, and the experience can be difficult. Many people describe it as one of the hardest and most important things they have done.

Coming Back

As the effects subside, you may feel exhausted, tender, or peaceful. Sleep may come easily or not at all. The next day is often quiet and reflective. Many ceremonies are held over multiple nights, with rest days in between.

The experience does not end when the ceremony does. What surfaces during ceremony often takes days, weeks, or months to process. This is called integration. Journaling, time in nature, conversation with trusted people, and sometimes professional therapy can all support this process.

Why Do People Seek Ayahuasca?

People come to Ayahuasca for many reasons:

  • Healing trauma — childhood wounds, grief, PTSD, abuse
  • Depression and anxiety — particularly when conventional treatments have not helped
  • Addiction — Ayahuasca has shown promise in treating substance dependence, alongside parallel research on ibogaine
  • Spiritual seeking — a desire to understand something beyond the material world
  • Self-understanding — clarity about life direction, relationships, patterns
  • Connection — to nature, to something larger, to oneself

There is a growing body of clinical research into Ayahuasca’s therapeutic potential. Institutions including Imperial College London, Johns Hopkins University, and the Beckley Foundation have published studies suggesting benefits for depression, anxiety, PTSD, and addiction. This research is early-stage and promising — but no medical authority currently recognises Ayahuasca as a treatment or cure for any condition. Anyone who tells you otherwise is overstating the evidence.

Ayahuasca is not for everyone. It is not a shortcut or a quick fix. It requires courage, commitment, and honest self-examination. One ceremony will not “fix” your life. What it may do is show you what needs attention. The work of changing happens afterwards, in the integration.

The Dieta Tradition

Ayahuasca ceremony is one part of a much larger healing tradition. Beyond the brew itself, there is a practice called the dieta (known as sama in the Shipibo language) — an extended period of communion with an individual master plant spirit.

During a dieta, a person lives in isolation in the jungle, follows strict dietary and behavioural restrictions, and repeatedly ingests a specific plant under the guidance of a curandero. The purpose is to form a personal relationship with the plant’s spirit and receive its teachings. Different plants teach different things: emotional healing, strength, clarity, protection, the ability to heal others.

This is what SoulLiana is primarily about. The Plant Index documents over 60 of these master plants. The Menor and Mayor page explains the two tiers of the dieta tradition. Each plant profile on this site represents a teacher within this system.

Is It Safe?

Ayahuasca carries real risks, both physical and psychological.

Physically: Ayahuasca contains DMT (a controlled substance in most countries) and MAO inhibitors. The MAOIs interact with several common medications and foods:

  • SSRIs, SNRIs, and other antidepressants combined with MAOIs can cause serotonin syndrome, which can be fatal. Stopping these medications and observing an appropriate washdown period under medical supervision is essential before ceremony.
  • Heart conditions, high blood pressure, epilepsy — the cardiovascular effects of the brew can be dangerous for people with these conditions.
  • Lithium, tramadol, stimulants — all dangerous in combination.

Psychologically: Ayahuasca can surface buried emotional material. For most people, this is therapeutic. For people with psychosis, schizophrenia, bipolar disorder, or severe dissociative conditions, the experience can be destabilising and potentially dangerous. If you have a personal or family history of these conditions, proceed with extreme caution and medical consultation.

Even without these conditions, difficult experiences happen. You may encounter fear, confusion, overwhelming emotion, or a sense of losing control. A good facilitator will be present to support you through this; a poor one will not — and this is the most common source of harm in the Ayahuasca world.

The quality of the facilitator matters more than any other safety factor. Legitimate curanderos will:

  • Ask about your medical history and medications before you drink
  • Explain what to expect honestly
  • Never pressure you to participate
  • Be present and attentive throughout ceremony
  • Have an emergency medical plan

Red flags include: no medical screening, pressure to participate, claims of guaranteed healing, sexual contact between facilitators and participants, and excessive secrecy about ingredients or the healer’s background.

For the full safety guide, see Safety & Harm Reduction.

Ayahuasca contains DMT, which is a controlled substance in most jurisdictions:

  • Peru: Legal and recognised as cultural patrimony since 2008.
  • Brazil: Legal for religious use (UDV, Santo Daime churches).
  • United States: DMT is Schedule I federally. Specific religious exemptions exist for the UDV and Santo Daime under RFRA.
  • United Kingdom: DMT is a Class A substance. No religious exemption exists.
  • Netherlands: Previously tolerated; a 2019 Supreme Court ruling reversed this.

This is not legal advice. Laws change and enforcement varies. Verify the current legal status in your jurisdiction. For more detail, see the Safety & Harm Reduction page.

Common Misconceptions

“It’s a drug”

In the Western sense of recreational substances, no. It is a medicine used within a specific ceremonial and cultural context. The experience can be challenging, often severely so. Nobody takes Ayahuasca for fun.

“It’s a cure for depression / addiction / PTSD”

Early research is genuinely promising. But no medical authority currently recognises Ayahuasca as a cure for any condition. Be wary of anyone — healer or retreat centre — who makes guaranteed healing claims.

“You’ll have life-changing visions”

Maybe, maybe not. Experiences vary widely. Some people have powerful visual journeys; others feel little visually but experience significant emotional or physical releases. There is no guaranteed outcome, and setting expectations can interfere with the process.

“One ceremony will change your life”

The ceremony may show you something important. But the change happens through integration — the work you do afterwards with what was revealed. Without integration, even the most powerful ceremony fades into memory.

“All shamans are trustworthy”

They are not. The growth of Ayahuasca tourism has attracted people with insufficient training, poor ethics, or outright predatory intent. Choose your facilitator carefully — it matters more than almost any other choice in this process. See Safety & Harm Reduction.

“Everyone should try it”

No. Ayahuasca is not for everyone. Medical and psychological contraindications exist. Beyond that, not everyone is ready or needs this particular form of medicine, and there are many paths to healing.
