Medicine doesn’t demand purity, but presence.
“Colonialism is like digesting one culture by another through different mechanisms, which has profoundly impacted ecosystems, indigenous lands, minds, and spiritual beliefs. … To heal, we must embrace a process of decolonization similar to a deep purge — an embodied unlearning of colonizing beliefs.” – Daiara Tukano
In the heart of the Amazon rainforest, where life pulses without asking permission and every being plays a role in the great balance of nature, ayahuasca has been consumed for generations. Not as an elitist sacrament, not as a rigid protocol, but as a living part of everyday life. A sick child, a celebration, a dream, a delicate moment in life, these are occasions to drink.
No forbidden food list, no abstinence from sex, no paranoia about salt or red meat. Alcohol before the arrival of the colonizers wasn’t a problematic habit. Today, where its use is, ayahuasca often serves as a form of healing. Our shamans advise avoiding pork, not because of a ceremonial taboo, but simply because they don’t eat or raise pigs. It’s more of a general orientation than a specific requirement for the ceremony.
The key is not purification, but relationship: with the plant, with others, with oneself. There is no notion of being “worthy” or “unworthy” of drinking, but rather of openness, readiness, and respect. Ayahuasca is medicine, not an exclusive sacrament. A daily tool, not a spiritual trophy.
And yet, in the Western world, the sacred drink of the jungle has taken another shape. Today, before drinking ayahuasca, one is expected to go through a sort of postmodern Lent: no sugar, no sex, no chili peppers, and ideally no strong emotions either. But where does this new orthodoxy come from? And most importantly, who does it serve?
The Origins of the “Pre-Ayahuasca Diet”
Contrary to popular belief, the idea that one must rigorously “prepare” through a strict diet before participating in an ayahuasca ceremony is not rooted in original Indigenous traditions. This concept emerged from a convergence between the mestizo vegetalista tradition in Peru, the therapeutic adaptation in clinical settings (like the Takiwasi Center) and the Western spiritual consumer’s hunger for purification.
Takiwasi, for example, introduced a hybrid model combining traditional Amazonian medicine with Western psychotherapy, where diets make sense in the context of extended retreats with master plants, not for a single ayahuasca ceremony. As founder Jacques Mabit notes,
“The diet is a powerful therapeutic tool that helps to build a relationship with the spirit of the plant — not a prerequisite for every use of ayahuasca.” (Mabit, 2007)
But this detail got lost in cultural translation. As ayahuasca moved into cities, weekend retreats, and spiritual packages, the diet became a generalized standard, a preventive measure for “energetic safety” and a way to increase the sense of exclusivity, discipline, and moral superiority. The diet became a symbol of spiritual elite membership, a new asceticism that promises enlightenment in exchange for sacrifice.
Indigenous Ayahuasca: Between Normality and Sacredness
In many Indigenous communities (Shipibo-Conibo, Yawanawá, Kaxinawá, Ashéninka) ayahuasca doesn’t require special diets. It’s drunk collectively with singing, vomiting, laughing, crying. People may make love the night before. They eat fried manioc and share the day’s hunted meat. The focus is not on control, but on relationship: with spirits, with the group, with the forest.
As anthropologist Glenn Shepard documents, among the Matsigenka of Peru,
“Ayahuasca is not associated with rigid rituals or dietary preparations, but rather with flexible contexts, often domestic and integrated into daily life.” (Shepard, 1998)
A direct witness, Marisol Yawanawá, shares:
“For us, we drink to sing, to listen to the spirits. There’s no need to fast or isolate — you need to be open and sincere.”
Of course, there are strict dietary practices in Amazonian tradition, but these are reserved for master plant diets: individual retreats lasting weeks or months, intended for deep healing, learning, or becoming a curandero. These include strict rules of isolation, silence, sexual abstinence, bland food, and devotion to the plant spirit.
Ayahuasca Ceremonies and Master Plant Diets: Two Very Different Practices
In Western discourse, there is often confusion between a simple ayahuasca ceremony and a master plant dieta, which may or may not include ayahuasca. This confusion has fueled the indiscriminate spread of rigid dietary rules even where they are unnecessary.
Here’s a summary of the key differences:
| Ayahuasca Ceremony | Master Plant Dieta |
| Collective drinking, often public or family-based | Individual retreat in isolation or semi-isolation |
| No specific physical preparation required | Requires sexual abstinence, bland food, silence, and solitude |
| Purpose: vision, connection, general healing | Purpose: to learn from a specific plant, open to its teachings |
| Duration: one evening to a few days | Duration: weeks or months |
| Conducted in group with music and a guiding shaman | Typically in solitude, with minimal social contact |
| Ayahuasca is the primary medicine | Ayahuasca may serve only as a bridge to the master plant (e.g., ajo sacha, chiric sanango) |
While the collective ayahuasca ceremony is a relational and often communal event, the dieta is a deep learning process, where the individual listens directly to the plant spirit. To confuse the two is to fail to recognize their different intentions, timelines, and contexts. It’s a crude and often colonial mistake. Like confusing a weekend class with a full apprenticeship: both involve learning, but with radically different depth and purpose.
The Western Need for Purification
In today’s world, saturated with stimuli, refined sugar, processed food, pollutants, pornography, burnout, and performance anxiety, it’s no surprise that the idea of “purifying” before drinking ayahuasca has become so popular. The diet becomes a form of expiation, a secular penance to gain access to the sacred. A way to say: “I’m doing it right. I deserve this.”
But the risk is that we spiritualize control, turning medicine into another kind of performance. And we project onto indigenous peoples an idealized, moralistic image that does not match reality. Indigenous people are not tantric vegetarians in abstinence; they are human beings with a different culture, who use the medicine to live, not to build a spiritual identity.
As anthropologist Beatriz Labate notes,
“The excessive sacralization of ayahuasca by Westerners often reflects more their own psychological and cultural needs than the reality of Indigenous practices.” (Labate & Cavnar, 2014)
And as Fabrizio Beverina writes in The Wings of Ayahuasca,
“Anything can happen in a ceremony. But what matters most is not what happens, but how we move through it — and especially, the human container that supports us in doing so.”
The medicine works in the relational field, not through individual performance.
A Reflection on Spiritual Colonialism
When the West imports sacred medicines, it often does so through its projections, anxieties, and moral filters. Ayahuasca gets “cleaned up,” “sanitized,” locked into systems of control. Its nuances, spontaneity, and relational dimension are lost.
The diet, as promoted today in many Western retreats, has become a form of soft spiritual colonialism, a way of bending medicine to our obsession with purity, individualism, and bodily control.
But the purity of the forest is not about chastity or the absence of excrement. The forest is wild, messy, full of fluids and enchantments. Purity, like peace in the jungle, includes all natural phenomena, innocence and brutality, decomposition and renewal. There, everything coexists, even shadow and grotesque aspects of the body.
And maybe it’s precisely this unconditional acceptance of nature, not just external, but intrinsic to the human being that makes an ayahuasca ceremony truly healing.
But What If the Diet Was Useful in Another Way?
This doesn’t mean we should throw everything out. In a world where the body is dissociated, energy is fragmented and attention is dispersed, reintroducing a form of energetic and relational diet can be beneficial. But not as a dogma, as an invitation. Not as a moral barrier, but as a practice of presence.
At Paojilhuasca Center, we often don’t impose a diet as a dogma. We invite people to reduce excess. Not because ayahuasca demands it, but because it’s the only way to truly listen.
The diet is not a gate to access ayahuasca. But it can be a lens to understand how polluted we’ve become. And maybe, starting from there, we can truly begin to heal.
So the final question is this:
In a world desperately seeking purity and control, are we ready to integrate, without distortion, the Amazonian cosmovision that invites us to return to the sacred through relationship, listening, and the natural complexity of the body?
