Every once in a while, the psychedelic world takes itself a little too seriously. Between clinical trial readouts, regulatory hearings, and long integration circles where someone always cries about their father, it's easy to forget the whole thing started with people getting curious about consciousness and having fun with it. So here's a small offering in that spirit: a crossword-style romp through the language of psychedelics and plant medicine, aimed at anyone who's been quietly reading about ayahuasca retreats at midnight and wondering what half the words mean.

Whether you're deep in research mode or just psychedelic-curious, working through terminology is genuinely useful. The vocabulary of this world overlaps traditional Amazonian shamanism, modern neuroscience, harm reduction culture, and clinical psychiatry — four fields that don't otherwise share a dinner table. Knowing what people mean when they say dieta, set and setting, or flood dose makes the difference between an informed choice and a wildly expensive surprise.

Why Vocabulary Matters Before You Book Anything

Retreats have their own dialect. Facilitators toss around words like purge, icaro, mareación, maloca, and master plants as if everyone grew up with them. Most of us didn't. And when you're about to spend two thousand dollars and a week of your life on a jungle floor, you want to know what people are actually saying.

I've watched more than one first-timer arrive at a Peruvian center and realize on day two they had no idea what a dieta involved. No salt. No sugar. No sex. No pork. No onions. Some places extend the list for months on either side of the ceremony. If nobody explained this on the intake call — and nobody asked — you've got a problem you can't easily solve.

So think of the puzzle below as a semi-serious way to test what you already know and fill in the blanks. Read the clues, guess the answers, and if a word makes you pause, look it up before you book.

The Clues: Across

Grab a coffee. If you get more than half of these without cheating, you've been reading up.

• 1 Across (9 letters) — The Amazonian brew whose name loosely translates to “vine of the soul.”
• 4 Across (8 letters) — West African root bark used for opioid-addiction interruption, associated with Bwiti tradition.
• 6 Across (5 letters) — The Andean cactus containing mescaline, also called huachuma.
• 9 Across (7 letters) — The traditional roundhouse where ayahuasca ceremonies are typically held.
• 11 Across (5 letters) — The sung medicine songs that guide a ceremony.
• 13 Across (10 letters) — The active tryptamine in ayahuasca, abbreviated three letters, spelled out here.
• 15 Across (5 letters) — Amazonian tree frog secretion used in a pre-ceremony cleansing practice.
• 17 Across (10 letters) — The controlled preparation diet observed before and after ceremony.

The Clues: Down

• 2 Down (8 letters) — Timothy Leary's three-word phrase, first word only. (Rhymes with bet.)
• 3 Down (10 letters) — The category of compounds ayahuasca inhibits, allowing DMT to remain orally active.
• 5 Down (7 letters) — The unpleasant-but-often-welcomed physical release during ceremony. Rhymes with splurge.
• 7 Down (8 letters) — The species most commonly cultivated for psilocybin retreats in the Netherlands and Jamaica.
• 8 Down (9 letters) — The post-ceremony process of translating experience into daily life.
• 10 Down (6 letters) — The Shipibo geometric patterns said to encode the songs themselves.
• 12 Down (7 letters) — The word for a curandero's protective and diagnostic breath, blown over the participant.
• 14 Down (5 letters) — What experienced practitioners insist you should always set before drinking the medicine.

How Many Did You Actually Know?

No shame either way. Even people who've done a dozen ceremonies routinely mispronounce icaro or forget which alkaloid does what. The point isn't trivia mastery. It's noticing where the gaps are.

If you struggled with the medicine-specific words — dieta, purge, icaros, kambo — that's a signal to slow down before booking. A good retreat will walk you through all of it in your intake process. A less careful one will assume you've done the reading. And there is a real difference between “I read a Reddit thread” and “I understand what I'm consenting to.”

If you struggled with the pharmacology terms — MAO inhibitors, tryptamines, psilocybin species — that matters too, especially if you're on any prescription medication. SSRIs and ayahuasca is the classic combination people don't take seriously enough. Neither does mixing MAOIs with certain foods. Your retreat's medical intake should catch this. Ask what their process is.

A Short Glossary for the Ones That Tripped You Up

Rather than leave you hanging, here are the ideas behind the trickier clues — expanded a little, because a one-line crossword answer doesn't do them justice.

Dieta. More than a food restriction. In the Shipibo tradition especially, dieta is a period of quiet, isolation, and dietary discipline meant to build a relationship with a specific plant. Retreat centers vary wildly in how strict they are. Some ask for a week of light preparation. Others expect months. Ask specifically what your retreat requires — and whether they'll enforce it or leave it to you.

Purge. The vomiting, crying, shaking, sweating, or occasional other-end release that often accompanies ayahuasca and, less dramatically, other plant medicines. Traditional practitioners consider it part of the healing, not a side effect. Bring your own tolerance for the fact that this is coming.

Icaros. The songs. Ceremonies are largely navigated through them — the curandero's voice is essentially the steering wheel. If you sit with a facilitator who doesn't sing (many neo-shamanic and some Western-led ceremonies don't), you're getting a different experience. Not necessarily worse. Just different.

Integration. The unglamorous part. What you do with the experience over the following weeks and months. Most of the real change happens here, not during the ceremony. Retreats that don't offer integration support — or at least a plan for it — are only doing half the job.

Set and setting. The phrase that keeps getting rediscovered. Your mindset going in, and the environment you're in, shape the experience more than the dose. A jungle lodge with a trained curandero and a first-week dieta will produce something different than the same brew in a friend's apartment. This is not a subtle difference.

The Hidden Word — and Why It Matters

In a proper crossword there's a hidden word running through the highlighted squares. In this one, the hidden word is respect. Not because it makes a good puzzle answer, but because it's the single quality that separates a healing experience from a chaotic one — respect for the medicine, respect for the tradition it comes from, respect for your own limits, and respect for the people sitting the ceremony with you.

Every horror story I've heard from someone who had a bad retreat comes back to a failure of respect somewhere in the chain. A facilitator who overserved. A participant who lied on their medical intake. A center that took bookings faster than it could train staff. The medicine itself is not the problem; it's rarely been the problem. The container around it is what makes or breaks the experience.

If the crossword sparked a curiosity to actually sit with one of these medicines — ayahuasca, psilocybin, San Pedro, ibogaine, or something else — a range of vetted plant-medicine retreats can be browsed on our marketplace here. Take your time choosing. The right retreat will not feel like a bargain; it will feel like a place that takes the work seriously. And if the language in this piece still feels foreign, treat that as your first task before you book anything. The words are the map. Learn them, and the terrain gets a lot less intimidating.
