Across northern Peru, huachuma does not work alone. It enters a nocturnal theatre of staffs, stones, swords, shells, perfumes, tobacco, coca, song and water, arranged upon a mesa whose objects face one another like a material argument about illness, power and repair. The cactus opens vista—the trained capacity to see what ordinarily remains entangled or remote—but the mesa gives that perception direction. Dangerous mishas may intensify or derail it; tobacco clears and protects; coca reads and reciprocates; lagoons, ruins, saints, winds and ancestors enter as active parties. This dossier follows that whole apparatus: from Formative-period cactus imagery and Chavín’s newly confirmed multi-plant psychoactive world to the living curanderismo of Piura, Lambayeque and La Libertad, and onward into global retreat culture, mescaline research and questions of conservation, law and biocultural ownership. It treats continuity as a problem to be demonstrated, not a romance to be assumed (Sharon, 1972; Glass-Coffin, 2010; Sharon, 2021; Rick et al., 2025).

Ayahuasca analogues are not counterfeit Amazonian sacraments. They are a historically specific transformation of an Indigenous pharmacological insight into a modular, mobile technology: pair a source of orally inactive tryptamines with a source of reversible monoamine-oxidase inhibition, and plants from different continents can enter the same biochemical circuit. In the 1980s and 1990s that proposition moved through Terence McKenna’s lectures, Jonathan Ott’s self-experimental ethnopharmacology, Jim DeKorne’s photocopied Entheogen Review, seed catalogues, basement glassware and the early internet. The result was a new cultural formation whose authorities were no longer only lineage, territory and ritual inheritance, but also reproducibility, chemical literacy, testimony, networks and the claimed sovereignty of the nervous system. It promised a democratisation of vision; it also redistributed danger, legal exposure, ecological extraction and the power to define legitimate consciousness (Ott, 1994; DeKorne, 1994; Rushkoff, 1994; St John, 2018a).

Ayahuasca is not one drink travelling unchanged through history. It is a vine and a family of preparations; a diagnostic instrument, teacher, medicine and dangerous power; a discipline of songs, diets, tobacco, breath, pattern and bodily ordeal; a medium of interethnic diplomacy and conflict; and, since the twentieth century, the Eucharist of Brazilian religions and a global therapeutic–spiritual economy. “Ayahuasca” is itself a Quechuan regional term now made planetary. Siona yajé, A’ingae yagé, Shuar natem, Shipibo-Konibo oni, Huni Kuin nixi pae, Santo Daime Daime and União do Vegetal Hoasca are not local labels for an otherwise identical universal object. Each names a relation among particular plants, persons, territories, songs, beings and regimes of authority. This page therefore treats the Ayahuasca Complex as a braided historical field: north-western Amazonian yagé traditions, western-Amazonian ayawaska and vegetalismo, and the Brazilian Daime–Hoasca religions—now transformed again through Indigenous revival, tourism, diaspora, prohibition and clinical science (Langdon, 2017; Labate and Cavnar, 2014; Gearin and Calavia Sáez, 2021; Favaron, Williams and Bédard, 2026).

Brazilian ayahuasca and Jurema traditions constitute an historically interconnected but institutionally differentiated religious field. Santo Daime, Barquinha and União do Vegetal emerged in twentieth-century Amazonian frontier settings; Jurema Sagrada and Catimbó-Jurema developed through Indigenous and Afro-Indigenous histories in northeastern Brazil. Later encounters with Umbanda, selected Candomblé-derived forms, Kardecism, esoteric Christianity, New Age networks and transnational psychedelic culture generated further formations, including Umbandaime and varied neo-ayahuasca churches. Across this field, sacramental plants are organised through distinct institutions, liturgies, ranks, spirit taxonomies, material arts, founder narratives, regimes of preparation and legal strategies. “Syncretism” is used here in its anthropological sense of historically situated religious synthesis and translation, with attention to differences in authority, cosmology and ritual practice (Goulart, 2008; Labate and MacRae, 2010; Dawson, 2012; Capone, 2010; Grünewald, Savoldi and Collins, 2022).

Bwiti denotes a historically changing family of initiatory, religious and therapeutic institutions centred principally in Gabon and neighbouring regions of equatorial Africa. Within these traditions, the bitter forest shrub Tabernanthe iboga participates in a larger ritual system comprising kinship, music, choreography, nocturnal vigil, chapel architecture, ancestor relations and the interpretation of visions. Southern Gabonese lineages, Fang reformulations and neighbouring healing associations vary in theology, gender, ritual office and the relative importance assigned to initiation, diagnosis, possession and Christianity. A recurrent initiatory pattern is structured as a passage towards the dead or the ancestral domain followed by return to communal life under the guidance of sponsors and ritual specialists. The twentieth-century development of ibogaine treatment constitutes a related but institutionally distinct history, proceeding through alkaloid extraction, addiction treatment networks, clinical investigation, regulation and patenting. This dossier therefore examines Bwiti and modern ibogaine medicine within one connected historical field while distinguishing their different sources, practices and evidential records (Fernandez, 1982; Fernandez and Fernandez, 2001; Bonhomme, 2006; Mary, 1999).

Across the Orinoco grasslands, the north-west Amazon, the Guiana Shield, the Caribbean and the desert corridors of the south-central Andes, finely divided plants have been made to travel on another person’s breath. Yopo and cohoba begin with the hard seeds of Anadenanthera peregrina; vilca and cebil follow its southern congener A. colubrina; epená, yakee and yãkoana emerge from the fragrant inner bark of several Virola trees, often worked with the aromatic leaf long known as Justicia pectoralis; tobacco powders are complete medicines in their own right and may also accompany, carry or alkalinise other preparations. What joins these practices is a ritual technology—powder, ash, tube, breath, bodily ordeal and trained interpretation. What keeps them distinct is everything that matters anthropologically: who may prepare and receive them; whether the work concerns prey, illness, ancestors, chiefly counsel or the defence of the forest; and whether the beings encountered are cemíes, xapiri, owners, enemies, ancestors or powers that cannot be translated without remainder (Schultes, 1967; Wilbert, 1987; Rodd and Sumabila, 2011; Kopenawa and Albert, 2013).

The clinical psychedelic ritual complex is a modern therapeutic and experimental assemblage. Psychoactive compounds are made clinically usable through screening, preparation, a controlled room, trained attendants, music, inward attention, adverse-event procedures, diagnostic categories and repeated measurement. Its dominant contemporary form descends from mid-twentieth-century psycholytic and psychedelic therapy, but it is continually remade by neuroscience, psychotherapy schools, pharmaceutical manufacture, clinic finance, intellectual property and regulatory review. Psilocybin, ketamine and MDMA occupy different pharmacological, experiential and legal positions within this shared apparatus. The name “ritual” here identifies a repeatable, symbolically charged sequence under institutional authority; it does not imply that the clinic is a traditional sacramental lineage (Hartogsohn, 2017; Dumit and Sanabria, 2022; Gukasyan and Nayak, 2022).

Eleusis was not a lost psychedelic recipe with a Greek temple attached. It was an initiatory machine extending from Athens to the Thriasian plain: proclamation, abstention, sea-purification, sacrifice, procession, obscenity, torchlight, sleeplessness, a grain-and-mint drink, and finally an encounter inside the Telesterion that initiates were forbidden to disclose. Its mythology moved through a mother’s grief, the arrested fertility of the earth, a daughter’s partial return from the dead and the establishment of rites promising a more hopeful relation to mortality. The kykeon mattered because it condensed that passage into something swallowed. Whether it also carried an entheogenic ergot derivative remains one of antiquity’s most productive—and most repeatedly overstated—hypotheses. This dossier therefore treats the drink, the sanctuary, the priestly institution, the civic pilgrimage and the phenomenology of darkness-to-light as one complex, while keeping pharmacological possibility separate from archaeological demonstration (Mylonas, 1961; Burkert, 1987; Ustinova, 2013; Mosurinjohn and Ascough, 2026; Antonopoulos et al., 2026).

Fly agaric is best understood as a mobile circumboreal assemblage whose strongest ethnographic centre lies in Siberia and the Russian Far East. There Amanita muscaria could serve, in different communities and periods, as divinatory agent, medicine, stimulant, social intoxicant and shamanic vehicle; its effects circulated through dried fruitbodies, trade, observation of reindeer and the documented reuse of human urine. Around that record has accumulated another history of hypotheses—Vedic Soma, Sámi magic, Norse berserkers, Christmas and medieval Christian imagery—whose evidence ranges from serious comparison to modern folklore. The mushroom’s contemporary life is different again: a global fairy-tale pictogram, a forest symbiont turned southern-hemisphere invader, a source of GABAergic research compounds and a poorly standardised commercial intoxicant. This dossier keeps those layers in relation without assigning them equal evidential weight (Jochelson, 1908; Saar, 1991a; Michelot and Melendez-Howell, 2003; Winkelman, 2022).

In the Sierra Mazateca, visionary medicine is not one plant and not one generic “psychedelic ceremony.” Mushrooms called ndi xi tjo—“little ones that emerge”—may speak as saints, children or divine persons; xka Pastora is approached as a quieter Marian presence; seeds of the Virgin open another route to knowledge; tobacco cleans, protects, treats and addresses forces that pharmacology alone cannot name. Their meeting-place is the velada: a nocturnal vigil in which darkness, paired distribution, prayer, abstinence, Catholic images, copal, candlelight and the improvised-poetic word of a chjota chjine turn altered perception toward diagnosis, lost persons, conflict, fate and repair. This page therefore follows a repertoire of medicines governed by one divinatory institution—not a blended preparation. It also follows what happened when that institution was recorded, published, toured, chemically isolated and transformed into a global psychedelic origin story (Munn, 1973; Faudree, 2015; Fagetti and Mercadillo, 2022).

The Wixárika peyote tradition is organised through movement across a sacred geography. Pilgrimage from Sierra Madre communities to Wirikuta re-enacts ancestral travel and the birth of the sun; ceremonial cargo holders carry obligations between people and distant place-beings; hikuri is encountered through a hunt in which peyote, deer and maize become ritually convertible; and nierika names a capacity and medium of seeing as well as classes of votive and artistic objects. The complex therefore joins cactus, route, office, offering, song and image. Its history cannot be reduced either to the chemistry of mescaline or to one classic ethnography: communities and ceremonial centres differ, journeys have adapted to roads and urban life, and commercial yarn painting has developed alongside—not simply replaced—older votive forms. This dossier follows those relations while marking the limits between archaeological evidence, Wixárika oral history, ethnographic interpretation and current political claims (Myerhoff, 1970; Myerhoff, 1974; Schaefer and Furst, 1996; Liffman, 2011; Neurath, 2015).
