Looking for an English-speaking truffle ceremony in Amsterdam? Stars Frequencies guides truffle ceremonies in Amsterdam: a day of about 7 hours, in a small group of at most 8 people (€295 per person) or as a 1-on-1 truffle ceremony (€495). Ceremonies are guided in Dutch or English. This page answers the questions expats and visitors ask most.
Land first, then the journey.
Maybe you live in Amsterdam and your Dutch isn't there yet. Maybe you're here for a few weeks and you've read that truffles are legal in the Netherlands. Either way, you want to understand what you're signing up for before you say yes. That's a good instinct. The people who come to Rosa often run their lives from their heads: they read, compare, think it through. You're allowed to do that here too.
Stars Frequencies is Rosa's practice in Amsterdam. She guides the truffle ceremony herself, from the free 30-minute intro call by phone to the check-in a week later. Meditation and sound healing with singing bowls are a fixed part of every ceremony, in a group and in a private ceremony alike. They give your head something to follow and help your body settle.
About language: Rosa guides in Dutch or English. Mention in your message or intro call that you'd like the ceremony in English.
Truffles (sclerotia) are legal in the Netherlands. They are not listed in the Opium Act. Mushrooms are a different story: fresh and dried mushrooms are on list II of the Opium Act, and fresh ones have been banned since 2008. Stars Frequencies only works with legal truffles.
Dutch law applies to everyone who is in the Netherlands, so the same rules count for residents and visitors. What it doesn't do is travel with you. The laws in your home country can be very different, and taking anything with you to another country is a separate question entirely. If you'd like to read more from an independent source, the Trimbos Institute publishes clear information in Dutch, and you can read more about the rules in our page on the legal side of a truffle ceremony.
Legal doesn't mean suitable for everyone. That's why every ceremony starts with a conversation, not with a booking.
Truffles themselves are the same. What differs is everything around them. On your own, nobody checks beforehand whether your medication or history makes this a bad idea. Nobody is there if it gets heavy. And there's no structure for the hours when your thinking mind has less grip than usual.
A guided ceremony is built around exactly those moments. Here is what that looks like in practice with Rosa:
For people who are used to being in control, that last part matters more than it seems. Letting go is not a requirement. It is a result. You don't have to force anything. The structure is there so you don't have to hold everything yourself. You can read the full approach on the safety and screening page.
Plan the ceremony as a whole day, not as one item on a busy holiday schedule. Keep the day itself completely free. Keep the day after clear too: no early flight home, no packed sightseeing, no parties. Give yourself time to land.
The full checklist is on the preparation page for the truffle ceremony. The costs, including private and duo prices, are on the prices page.
“The preparation was so thorough. The intro call put me at ease right away. During the ceremony I felt held the entire time. Thank you, Rosa.”
About half of the participants are doing it for the first time. No experience needed. More stories are on the experiences page.

Yes. Group ceremonies are in Amsterdam, about 10 minutes from Schiphol airport, and occasionally in Blaricum. Private ceremonies take place in Blaricum. You receive the exact address after the intro call. Don't drive yourself on the day: arrange a taxi or someone to pick you up.
Yes. Truffles (sclerotia) are legal in the Netherlands and are not listed in the Opium Act, and Dutch law applies in the same way to residents and visitors. Mushrooms are banned: they are on list II of the Opium Act. The laws of your home country can be different, so check them yourself. Stars Frequencies only works with legal truffles.
Yes, if you like. Rosa guides in Dutch or English. Mention it when you send her a message on WhatsApp or during the intro call.
A truffle ceremony at Stars Frequencies takes about 7 hours. Keep the whole day free and plan a calm day after it. The group ceremony runs from 11:00 to 18:00. Before the day there is a free intro call of 30 minutes by phone, and after it you receive a truffle guide with everything you need to know, including advice on food.
Bring comfortable clothing in layers, because it can get warm or cool. Add a bottle of water, your intention written down, a journal if you like, a personal object or photo as an anchor, and the name and number of an emergency contact. A meal is part of the day.
Always bring it up in the intro call, because it depends on the medication. With some medication a ceremony isn't possible, with others only after talking to your doctor. With SSRIs and SNRIs the effect can be strongly reduced or unpredictable. Never stop medication on your own. Rosa honestly says no if it isn't responsible.
A guided ceremony adds screening, preparation and someone who stays with you the whole time. Rosa checks your medication and health beforehand, tunes the amount to each person based on the intake and your experience, and stays in the room for the whole ceremony. The group is small, meditation and sound healing are a fixed part of the day, and there is an emergency protocol. On your own, none of that is there.
A truffle ceremony is not suitable if you or a first-degree family member ever had psychosis or schizophrenia, if you have bipolar type I or dissociation, during an acute mental health crisis or suicidal thoughts, or if you take lithium or MAO inhibitors. The same goes for severe heart or vascular disease, unstable elevated blood pressure, epilepsy, and pregnancy or breastfeeding. Other medication and conditions are always discussed in the intro call.
A difficult moment can happen, and you won't be alone with it. Sometimes fear, sadness or restlessness comes up, or something that has been pushed away for a long time. Rosa is in the room for the whole ceremony. If someone panics, Rosa handles it with care and knows how to help that person calm down. A gentle touch only happens with your permission.
No. About half of the participants are doing it for the first time. No experience needed. You start with a free intro call of 30 minutes, you get preparation for at home, and on the day itself Rosa is there the whole time.
A group ceremony costs €295 per person, with at most 8 people. A 1-on-1 truffle ceremony costs €495. A duo costs €425 per person. For 3 people you pay €350 per person, for 4 people €325 per person. You only pay once the intro call shows it suits you.
Letting go doesn't happen on command. It isn't a condition for taking part, it's something that may happen. If it doesn't come right away, that isn't failing. Rosa is in the room for the whole ceremony, tuned in to you, and you can always ask her for support.
The amount is tuned to each person, based on the intake and your experience. It isn't a competition: you don't have to go as deep as possible. Tell Rosa what you find scary and she takes it into account.
You don't have to. In the group everyone is busy with their own experience and you only share what you want. If you want no one else there, choose the private ceremony: the day is then just for you, or for you and the people you bring (up to 4 people).
Not sure yet whether this is for you? Send Rosa a message. Ceremonies are guided in Dutch or English. The intro call is free and takes 30 minutes, and you only pay once it's clear the ceremony suits you.
