This dossier concerns two Brazilian religious traditions in which a psychoactive brewed sacrament is centrally embedded in doctrine, community authority, moral discipline, and accounts of personal change: Santo Daime and the União do Vegetal, usually abbreviated UDV. Both are often grouped under the modern shorthand “ayahuasca religions,” but that label can hide important differences in history, leadership, liturgy, vocabulary, institutional organization, and the meanings participants assign to experience. Santo Daime commonly calls its sacrament Daime, while UDV commonly calls its preparation hoasca. Their shared use of preparations ordinarily associated with Banisteriopsis caapi and a DMT-containing admixture does not make their ceremonies interchangeable, nor does it make every participant’s experience pharmacologically or spiritually identical. The research problem implied by “conversion” is broader than a dramatic, one-time change of belief. Participants and observers may describe conversion as joining a congregation, accepting a lineage of teaching, revising habits, recovering a sense of purpose, adopting ethical duties, or learning to interpret vivid inner events through a church’s cosmology. Some people report a decisive ceremony, vision, bodily catharsis, or encounter with a sacred presence. Others describe a gradual process of attendance, friendship, hymn learning, mentoring, confession, service, and repeated ritual participation. There are also participants whose commitment is partial, temporary, exploratory, or negatively affected by difficult experiences. A careful account therefore treats conversion as a social and interpretive process rather than assuming that a psychoactive effect directly produces religious belief. Reported experiences include altered visual imagery with eyes closed or open, intensified color and pattern, autobiographical memories, tears, nausea and vomiting, tremor, heat or cold, fear, awe, perceived moral insight, and a pronounced sense that ordinary self-boundaries have shifted. In Santo Daime, singing, collective formation, instrumental accompaniment, and in some works rhythmic dancing or standing can structure attention and endurance. UDV sessions are generally characterized in accounts as more seated and discursive, with formal teaching, hierarchy, and collective discipline, though procedures vary by local center and occasion. Participants may regard bodily discomfort as purification, instruction, or a challenge to be worked through. Those meanings are religious interpretations, not clinical diagnoses or evidence that a physiological reaction has a supernatural cause. Acute effects can also be understood through the brew’s psychoactive constituents, dose variation, fasting, sleep loss, expectancy, social suggestion, music, lighting, group synchronization, prior mental state, and the powerful setting created by ritual authority. None of those ordinary explanations settles the truth or falsehood of adherents’ metaphysical commitments. Conversely, a sincere and meaningful report of a vision, healing, spirit encounter, or apparent telepathy does not independently verify a paranormal event. Observational studies of long-term members are especially hard to interpret because congregants may differ from nonmembers before joining, may receive substantial social support, and may describe wellbeing according to tradition-specific ideals. The period from 2010 onward is important because Brazilian regulation, international branches, litigation, public-health discussion, tourism, online testimony, and the wider psychedelic revival all increased the visibility of these traditions. Brazil’s 2010 CONAD resolution is commonly recalled as part of a framework recognizing and regulating specified religious ayahuasca practices, but its exact scope, conditions, subsequent application, and relationship to earlier decisions require checking against official legal texts. In the United States, the UDV’s major Supreme Court religious-freedom decision was issued in 2006, not 2011; later compliance and expansion debates should not be confused with the date of that ruling. Legal recognition for one organized group or jurisdiction is not a general finding that all preparations, facilitators, therapeutic claims, imports, or ceremonies are lawful or safe. Commercial and media forces complicate transmission. International interest has generated books, documentaries, workshops, retreat marketing, online recruitment, and a vocabulary of “healing,” trauma release, authenticity, and transformation. These can introduce seekers to churches, but they can also blur distinctions between membership-based religious work, indigenous and mestizo Amazonian traditions, clinical research, and profit-oriented psychedelic tourism. Critics raise concerns about cultural extraction, charismatic authority, uneven screening, medical risk, sexual or financial exploitation, and commercialization of Amazonian knowledge. Adherents and some scholars counter that formal congregations preserve ritual constraints, communal accountability, and a lineage of practice that differs substantially from individual consumer use. The most defensible synthesis preserves both the reported spiritual significance of conversion narratives and the unresolved methodological, ethical, legal, and causal questions surrounding them.

Chronology.
The supplied subject is principally framed from 2010 onward, but earlier institutional histories are necessary to distinguish the two traditions. Santo Daime is generally traced to Raimundo Irineu Serra and Acre in the early twentieth century, while the UDV is generally traced to José Gabriel da Costa, known within the tradition as Mestre Gabriel, and to 1961. Later expansion in Brazilian cities and abroad created the institutional settings in which conversion narratives became more visible to researchers and courts.
The chronology below separates recalled historical framing from events that should be verified in primary legal, institutional, and ethnographic sources. It does not treat a founding account or a participant’s remembered transformation as proof of any supernatural claim.
People, Organisations, and Setting.
Santo Daime developed in Amazonian Brazil and later acquired urban and international communities. Raimundo Irineu Serra is commonly recognized as its foundational figure, and Sebastião Mota de Melo is widely associated with an important later expansionist lineage. “Santo Daime” is not a single uniform organization: congregations, lineages, local leaders, rules, music repertoires, and approaches to outsiders can differ. Labels such as CEFLURIS may identify particular historical or organizational currents and should not be used as a blanket substitute for every Daime community.
The União do Vegetal, formally known as Centro Espírita Beneficente União do Vegetal in many contexts, was founded by José Gabriel da Costa and developed a more explicitly centralized and hierarchical institutional identity. Its Brazilian development included Amazonian regions and Brasília, followed by international branches. The organization’s use of the title Mestre Gabriel and its framing of hoasca as a disciplined religious sacrament are internal religious language, not neutral confirmation of revelation claims.
Ceremonies occur in deliberately arranged social settings rather than in a laboratory vacuum. Depending on the house and tradition, relevant features may include formal dress, prayer, hymns, instruments, seated instruction, standing formation, dancing, timed service of the brew, gendered or age-based arrangements, senior members, and rules concerning speech and conduct. Brazil is the historical center, but European and North American congregations operate under local legal, cultural, migration, and language conditions. These settings can influence both what is felt and the vocabulary through which an experience is later narrated.
Reported Phenomena and Religious Interpretation.
Accounts of the sacrament’s effects often describe bitter taste, nausea, retching or vomiting, abdominal discomfort, sweating, changes in temperature sensation, dizziness, muscular tension, crying, laughter, fatigue, insomnia, and changes in appetite. Visual reports can include geometric forms, moving patterns, unusually vivid color, imagined landscapes, symbolic figures, remembered scenes, or imagery judged by the participant to be externally real. Auditory and bodily reports may include intensified music, silence felt as significant, internal dialogue, a sense of vibration, heaviness, lightness, or altered passage of time. Frequency and intensity vary with the person, the preparation, amount ingested, prior use, setting, and unrecorded factors.
Santo Daime participants may speak of mirações, sacred presences, spiritual combat, healing, moral correction, or instruction through hymns and collective work. UDV participants may speak of burracheira, concentration, teachings, spiritual evolution, moral responsibility, and learning obtained in an ordered session. These are tradition-specific interpretive categories. A vision of a deceased relative, a perceived diagnosis, an apparent message, or a sense of communication at a distance may be deeply consequential to a participant without establishing that the perceived entity, diagnosis, message, or communication occurred independently of altered perception.
Conversion narratives commonly join sensory intensity to behavioral change. Individuals may report reducing alcohol or other drug use, changing relationships, increasing prayer or service, becoming more emotionally expressive, or accepting church discipline. Others report distress, shame, interpersonal conflict, disappointment, or leaving a group. Apparent improvements cannot be attributed solely to the brew from self-report alone, because selection into membership, mutual support, expectation, psychotherapy-like disclosure, lifestyle changes, and regression from a difficult period may all contribute.
Investigation and Research History.
Anthropologists, historians of religion, psychologists, psychiatrists, pharmacologists, legal scholars, and public-health researchers have approached these traditions from different premises. Ethnographic work can document ritual form, conversion stories, authority, music, kinship, and local meanings, but it does not by itself establish pharmacological efficacy or metaphysical truth. Biomedical and psychological work can examine symptoms, cognition, and associations with wellbeing, but small samples, self-selection, expectancy, legally constrained recruitment, and culturally narrow outcome measures limit causal claims.
Ayahuasca preparations are commonly described as combining beta-carboline-containing Banisteriopsis caapi with a DMT-containing plant such as Psychotria viridis, although actual materials and concentrations can vary. A pharmacological account may help explain altered perception and gastrointestinal effects through the interaction of psychoactive compounds with the body. It does not explain away all religious meaning, but neither does it demonstrate spirits, miraculous cures, privileged paranormal cognition, or the objective truth of revealed doctrine.
Research ethics are especially important because members may be vulnerable to stigma, legal jeopardy, pressure from authority figures, or misrepresentation by outsiders. Investigators should distinguish active members, former members, casual visitors, and commercial retreat customers; obtain informed consent; avoid forcing translations of sacred terms; record adverse as well as desired effects; and avoid presenting an institutional membership sample as representative of all ayahuasca users.
Disputes, Risks, and Alternative Explanations.
A central disagreement concerns explanatory level. Religious participants may attribute conversion to divine agency, the intelligence of the sacrament, ancestors, or sacred teaching. Secular observers may emphasize serotonergic psychoactivity, suggestion, patterned ritual, social belonging, and autobiographical reframing. A rigorous dossier need not select a metaphysical winner: it can report that participants make spiritual attributions while noting that available observation does not independently adjudicate them.
Safety and authority are disputed both inside and outside these traditions. Formal screening, abstinence rules, trained leaders, sober attendants, ritual norms, and long-term membership may reduce some risks, but they cannot eliminate risks from psychiatric vulnerability, drug interactions, medical conditions, inaccurate dosing, coercion, accidents, adverse reactions, or misconduct. A legally recognized church can still contain local variation, and an apparently traditional setting is not automatically safe, ethical, clinically appropriate, or exempt from law.
Critics of international expansion point to commodification, unequal access to Amazonian knowledge, racial and class tensions, controversial leadership, and blurred borders between spiritual care and unlicensed treatment. Defenders emphasize the traditions’ Brazilian roots, ethical codes, collective responsibility, and the difference between religious sacrament and a commercial psychedelic product. Each position requires case-specific evidence; neither should be generalized from isolated scandals, promotional claims, or idealized self-descriptions.
Transmission, Retellings, and Commercial Influences.
Experience is transmitted through repeated attendance, oral teaching, hymns, ritual etiquette, family and friendship networks, membership documents, public testimony, and the authority of senior members. Santo Daime’s sung repertoire can provide a shared framework in which bodily sensations and visions become morally interpretable. UDV’s ordered teaching and organizational hierarchy can similarly shape how members discuss revelation, healing, responsibility, and spiritual progress. In both cases, transmission is collective and recursive: the group supplies a vocabulary, and personal testimony can reinforce the group’s vocabulary.
Since 2010, public attention has increasingly traveled through social media, streaming media, books, podcasts, news coverage, litigation, and the broader market for psychedelic wellness. These channels can simplify a long process of religious affiliation into a dramatic “one-night conversion” story. They may also conflate Santo Daime, UDV, Indigenous-led ceremonies, neo-shamanic networks, clinical trials, and tourism businesses, despite material differences in governance and purpose.
Commercial language can alter expectations before attendance. Promises of trauma healing, sobriety, creativity, mystical certainty, or personal reinvention may influence who arrives, what they notice, and how they later remember the ceremony. Such messaging should be treated as a source of expectation and institutional economy, not as validated evidence of a treatment effect or a guarantee of spiritual transformation.
Cross-Case Connections and Comparative Motifs.
This subject is useful for comparing traditions in which unusual perception is institutionally interpreted rather than treated as an isolated anomaly. Relevant motifs include guided ingestion, controlled music or speech, collective synchronization, disciplined bodily ordeal, interpreted visions, charismatic lineage, conversion through repeated practice, moral reform, healing testimony, legal accommodation, and conflict over cultural ownership. These motifs can be compared with other altered-state religions, pilgrimage healing, charismatic revival, mediumship, and high-control group studies without assuming that all such phenomena have a common cause.
For psi-oriented comparison, claims of visions, communications with nonordinary beings, knowledge of another person’s condition, or apparent telepathy should be coded as reports occurring in a suggestive psychoactive and ritual context. Useful comparative questions include whether information was documented before confirmation, whether independent witnesses existed, whether alternative cues were excluded, and how later retelling changed the account. Most conversion testimony is better suited to the study of meaning-making, memory, authority, and altered consciousness than to evidencing anomalous information transfer.
Limits of the Recalled Record.
This is a recalled synthesis, not a source-checked literature review. It should not be used to establish exact dates, organizational names, membership numbers, legal permissions, ceremonial procedures, efficacy findings, adverse-event rates, or the content of any group’s doctrine. Church practice is internally diverse, and accounts by critics, members, former members, researchers, courts, and commercial operators may each emphasize different facts.
The terms ayahuasca, Daime, and hoasca carry overlapping but nonidentical histories and should be retained when a source uses them rather than flattened into a single category. Future work should check official Brazilian regulation, court materials, ethnographies, peer-reviewed studies, and community-authored material; compare Brazilian and transnational settings; and include negative, ambivalent, and nonconversion experiences. No part of this dossier verifies paranormal perception, miraculous healing, spiritual beings, or causal therapeutic benefit.
