Nahua (Nāhuatl-speaking peoples)
Central Mexican highlands; historic Mexica heartland and contemporary Nahua communities
Behind the Nahuatl word teonanácatl lies an archive of ritual practice that never entirely died — from the mushrooms of the Florentine Codex to a living medicine of thunder, rain, and healing.
The people and the record
“Nahua” names the Nahuatl-speaking peoples of central Mexico — among them the Mexica, whose empire the Spanish conquered in 1521. Their advantage, for an archive like this, is documentary: the Nahua world was written down early, both by Spanish friars and by Nahua authors themselves, giving the mushroom a primary-text foundation that few traditions can match.
Teonanácatl in the Florentine Codex
The Florentine Codex, compiled under Bernardino de Sahagún with Nahua collaborators around 1577, preserves a vivid passage in Book 9: banquet guests eat “little black mushrooms” that intoxicate them and bring visions, laughter, and weeping.1 Book 11 records the word teonanácatl. This is not modern psychedelic nostalgia projected backward; it is a sixteenth-century account, part-authored by Nahua hands, of mushrooms used within feast and ritual.
Thunderbolt medicine
The most interesting recent argument is that Nahua mushroom use survives inside a larger logic of lightning and rain. Scholars describe ritual specialists who are called — marked by lightning, dreams, visions, or persistent illness — rather than self-appointed, and a medicine in which mushrooms are tied to storm, water, and fertility.2 The association is not arbitrary: mushrooms erupt with the rains, and the fungal body is bound to a divine meteorology reaching back to rain deities of the Tlaloc complex.
Not one isolated sacrament
Nahua entheogenic medicine can be multi-substance: mushrooms are reported in combination with other ritual plants such as yauhtli (Mexican tarragon, Tagetes lucida).2 Keeping that complexity visible matters, because it resists collapsing a whole therapeutic world into the single Western category of “the mushroom trip.”
Colonialism, and today
Denounced as idolatry in the colonial period and controlled as a narcotic in the modern one, Nahua mushroom practice nonetheless persists in places — and current scholarship describes it as endangered. It survives as a living tradition under pressure, not a recovered fossil.

Names of the mushroom
| Name | Language | Translation / gloss |
|---|---|---|
| teonanácatl † | Nahuatl | read variously as ‘flesh of the gods’ or ‘sacred/marvellous mushroom’; the exact gloss is debated |
| teotlaquilnanácatl † | Nahuatl (contemporary) | a present-day Nahua name for Psilocybe caerulescens; gloss reconstructed |
| apipiltzin † | Nahuatl (contemporary) | — |
Indigenous- and local-language names appear in many spellings across dialects, publications, and orthographies. We record them as given in our sources and do not standardise them or invent translations. A dagger (†) marks a form our sources flag as uncertain.
Historical record
- c. 1577
The Florentine Codex
Sahagún's Nahua collaborators describe banquet guests eating 'little black mushrooms' that intoxicate and bring visions (Book 9), and record the word teonanácatl (Book 11).
Historical - 16th c. onward
Suppression as idolatry
Missionaries denounce mushroom rites; practice retreats from public view.
Historical - 1938–2008
Species identified
Schultes and later Gastón Guzmán connect colonial terms to specific modern species.
Later scholarly interpretation - 2020s
Thunderbolt medicine
Recent scholarship frames living Nahua mushroom use within a wider medicine of lightning, rain, and dreams — now endangered.
Living tradition
Evidence
The support for this entry, separated by kind. Different kinds of evidence carry different weight.
- Colonial text
- The Florentine Codex (Books 9 & 11), a sixteenth-century Nahua-authored source.
- Later scholarly interpretation
- Species attributions by Schultes and Guzmán mapping colonial terms onto modern taxonomy.
- Contemporary ethnography
- Contemporary scholarship on Nahua thunderbolt medicine (e.g. González Romero, 2025).
- Linguistic evidence
- Living Nahuatl mushroom names such as teotlaquilnanácatl and apipiltzin.
What remains uncertain
- Which species the colonial texts describe is a reconstruction; early writers rarely recorded diagnostic detail.
- The literal meaning of teonanácatl is debated ('flesh of the gods' is a translation choice, not a settled fact).
- The extent and distribution of contemporary continuity is unevenly documented.
