How to Prepare for Ayahuasca: A 30-Day Plan, Week by Week

If you search for how to prepare for ayahuasca, nearly everything you find begins with food: what to cut, for how long, in what order. Food matters, but it is not where preparation starts. The step with the longest lead time, and the only one that can change whether you should go at all, is the medical one. This plan puts it first for that reason.

Think of the month as four weeks that count down to your ceremony date. Pick the date first, then read backward from it.

Week 4 (days 30 to 22): safety and decisions

1. Do the medical review. Write down every medication and supplement you take, your psychiatric history and your family's, and any heart, liver or chronic conditions. Take that list to your doctor and ask directly whether there is any contraindication or interaction. This comes first because some answers take weeks to act on. Ayahuasca contains MAO inhibitors, and combined with serotonergic antidepressants that can be dangerousMAPS 1995Systematic review 2020 If a medication has to be tapered, that happens on your doctor's schedule, not yours. Our article on ayahuasca and antidepressants explains the mechanism, and who should not take ayahuasca covers the full list.

2. Shortlist three centers and send each the same questions. Compare the written answers, not the websites. Our list of ten questions to ask before you book is built for this, and the red flags article covers what a bad answer sounds like. A serious center asks about your health before accepting you.

3. Start the clean-up clock. Cut alcohol and recreational drugs now. It is the simplest change and the one with the longest runway.

Week 3 (days 21 to 15): commit and lighten

Confirm and book your center once the medical review is clear. Serious centers often have waitlists of weeks or months, which gives your preparation room to breathe.

Buy travel insurance that covers medical evacuation. Many centers are hours from a hospital, so basic travel insurance is not enough. People leave this for last, and it is the thing that brings the most peace of mind.

Begin simplifying what you eat. Less ultra-processed food, less red meat, and a gradual reduction in caffeine rather than stopping it overnight. Some of the diet is about safety and some is tradition, and it helps to know which is which. Read the diet, explained before you decide how strict to be, and follow your center's list where it differs from anything general.

Write your reason. One page: why now, and what you are hoping to look at. Return to it a few times over the following weeks. If the reason changes, that is useful information.

Week 2 (days 14 to 8): the base diet and turning inward

Settle into simple food: vegetables, rice, white fish, nothing processed. Start turning down the noise too, with less news and less social media, and a short daily stretch of stillness, ten minutes is enough. This is also the week for the three conversations people postpone:

• A trusted person. Tell them everything: where you are going, when, and who your emergency contact is. Give the center their details and give them the center's.
• Worried family. You do not need to defend the spiritual side. Say what is true and reassuring: a supervised center, a medical review, a month of preparation.
• Work. Time off is time off. You do not owe anyone an explanation.

Week 1 (days 7 to 0): fine-tuning and arriving

The preparation is done. This week is about settling it.

• Stricter food as the days pass, with no added salt or sugar, and in the last 24 to 48 hours exactly what your center tells you. A partial fast is common, but the instructions are the center's to give.
• Protect your sleep and move gently. Anxiety usually rises as the date nears, and that is normal.
• No big decisions and no farewell party. Keep the night before calm.
• Practice a breathing technique you can use when the experience gets hard. You will not remember to learn one in the middle of the night.

The days after belong to the plan too

Preparation and integration are one arc, not two projects. Decide before you leave what the first three days look like: no irreversible decisions, real rest, and writing down what happened before it fades. Specialists describe the period after as one of the most delicate parts of the whole processICEERS Our guide to the first 72 hours covers it, and integration covers the month that follows.

If you have less than 30 days

Many people start with the date already close. That is workable if you are honest about what gets compressed:

1. The medical review comes first, today. It is the one step that cannot be shortened. If you take an incompatible medication and there is no safe window, postpone.
2. Compress the diet into two weeks, going straight to the simple base diet and strict for the final week.
3. Do not compress your reason or your plan for afterwards. Those matter as much on 14 days as on 30.
