Truffle ceremony for organisations
A truffle ceremony for your team or organisation, on request.
Three concerns we hear every week. With honest answers.
"I will lose control."
The active substance in magic truffles temporarily quiets the part of your brain that constantly monitors and controls. Not: you lose control. Instead: the inner critic grows quieter. You remain aware of your surroundings. You can talk, move, or ask your facilitator to be with you. That is enough.
“I could easily let go of control and surrender to the process. The setting and safe space Rosa created made that possible.”
"I will have a bad trip."
Professionals don't call it a bad trip, just a difficult moment. Difficult experiences under guidance are often the most valuable of the day. They open something that has been stuck for a long time. We have guided more than 200 people. Your facilitator knows when to be present and when to give space.
“I feared a bad trip. Her professionalism is not in grand words, but in how safe she makes you feel.”
"I don't know what will come up."
Nobody knows beforehand. And that is exactly why there is an intro call. We listen for 15 minutes to your situation, intention and where you stand. The ceremony is then prepared for you, not a standard programme. The uncertainty is the starting point, not the problem.
“It opened a door I thought was closed.”
Mandatory intake before every ceremony. Medication, medical history, contraindications. No intake, no participation.
Every dose is determined personally. No standard approach. Your nervous system is the starting point.
Difficult experiences are guided, not taken away. Your facilitator is present and attuned to you throughout the entire day.
Truffles do not fall under the Opium Act. Stars Frequencies operates transparently and within the legal framework.
We reach out in the week after the ceremony. No drop-and-go: the support does not stop when you go home.
Before the day
15 minutes by phone or WhatsApp. We listen to where you are, you ask questions. Together you decide if the day is right for you.
"The intro call put me at ease right away." · Merel
Morning ritual
The day starts gently. Arrival, introductions, a short meditation. No rush.
Opening
Singing bowls, breathwork, intention-setting. Your nervous system calms. Truffles work deeper when your body is relaxed.
The work
The core of the day. Your facilitator is present and attuned to you. She senses when to be close and when to give space.
Closing
There is space to share about your experience and you receive a healthy meal. What emerged begins to settle here.
The week after
One week after the ceremony there is a personal check-in call. You are guided through what came up. Not a one-shot: this is built into the format.

Most people who attend a truffle ceremony at Stars Frequencies are doing it for the first time. Experience with meditation or plant medicine is not required. Rosa always starts with a 15-minute intro call. Together you explore whether the ceremony is right for you at this moment. If there are doubts, they are discussed. You do not have to decide anything before that call. Stef did it for the first time: "Reunited with my inner child and from there I feel so much energy and love for life."
Truffles are legal in the Netherlands. They do not fall under the Opium Act. Magic mushrooms (the dried form) are prohibited, but truffles (sclerotia) are not. Stars Frequencies works exclusively with truffles and fully within the legal framework. Read more about safety and protocol →
A difficult experience can occur. In professional facilitation we do not call this a "bad trip" but a difficult moment. Difficult experiences under good guidance are often the most valuable moments of the day. Rosa is present the entire ceremony and actively guides you through what arises, without taking it away. The intro call significantly reduces the risk: people for whom the ceremony is not suitable at this moment do not participate. Daniel: "Her professionalism is not in grand words, but in how safe she makes you feel." Read about the safety protocol →
Yes. Therapy and coaching work primarily cognitively: you analyse, understand and recognise patterns. A truffle ceremony works through a different mechanism. The active substance in truffles temporarily quiets the Default Mode Network, the part of the brain that continuously categorises and reflects. That creates an opening for experiences that you cannot reach in conversations. The two are not mutually exclusive. Many participants combine therapy with a ceremony. Rachelle: "The ceremony gave me insights I hadn't reached in years of therapy."
If you understand your situation but feel nothing around it, a truffle ceremony is a good match. The active substance in truffles temporarily lowers activity in the analytical part of the brain. That creates space for recognition you feel in your body, not just understand in your head. D. van Rijk: "Grounded and accessible, no heaviness or woo, just genuine care for the nervous system."
Structure, screening and format are fundamentally different. At Stars Frequencies: mandatory medical screening beforehand, maximum 8 participants, sound healing integrated in the ceremony, intake and integration call as a fixed part of the programme. A recreational or festival setting has no intake, no individual support and no integration. The difference is not the substance, but the container. Read about the protocol →
SSRI use is a serious contraindication. In most cases truffles work significantly less well or not at all in people who use SSRIs, due to interaction at serotonin receptors. Depending on the type of medication, participation is sometimes possible after a washout period, always in consultation with your treating physician. You always discuss this in the intro call. We decide together with you based on your specific situation. Ask your question via WhatsApp →
The maximum group size is 8 people. That is a deliberate choice: we want to know everyone personally and actively guide the atmosphere in the circle. Larger groups make that impossible. For those who want maximum privacy there is also a private ceremony, where the venue is exclusively yours.
Pregnancy is an absolute contraindication for a truffle ceremony. Using truffles during pregnancy has not been researched for safety for the unborn child and is therefore not advised. This also applies during breastfeeding. Contact us if you are unsure about your situation. Ask your question via WhatsApp →
You can reschedule to another date free of charge up to 14 days before the ceremony. Between 14 and 7 days before the ceremony a 50% cancellation fee applies. Within 7 days no refund is possible. Questions about rebooking? Send a message via WhatsApp →
That fear is familiar to almost everyone who comes for the first time. In the closing circle, people describe the opposite: the presence of others with the same uncertainty made it safe. Vulnerability in a ceremony feels different from daily life. When someone cries, it gives others permission. Sharing in the circle is always voluntary. You choose what you say. We actively guide the atmosphere, including emotionally.
The terms truffle journey and inner journey describe what happens during a truffle session: a deep exploration of your own inner world. Truffles are a form of plant medicine that opens a state of consciousness in which you can examine patterns, emotions and memories from the inside. The inner journey is not escapism. It is a guided, intentional experience that many participants describe as the most impactful they have ever had.
A trip sitter stays present during a psychedelic truffle session to provide safety. Rosa's role goes further: as a ceremony facilitator she creates the setting, guides the opening and closing, provides live sound healing and is actively present throughout the entire day. When difficulty arises or support is needed, she is immediately there. That is the difference between a trip sitter and a professional ceremony guide.
Truffles are increasingly recognised as plant medicine: a natural substance with therapeutic value when used under professional guidance. Researchers at Johns Hopkins, Imperial College London and MAPS confirm this in large-scale clinical studies. Stars Frequencies works from the same serious approach, not recreational, but as part of a full ceremonial process with intake, guidance and integration.

Many people who come to Stars Frequencies have already gone through a trajectory. Therapy. Coaching. Books. They understand their situation. But the feeling that something is stuck remains. Therapy works cognitively. A truffle ceremony works through a different mechanism. Rachelle: "The ceremony gave me insights I hadn't reached in years of therapy."
Structure, screening and real guidance: that is the dividing line. A recreational setting has no intro call, no individual attention and no integration. At Stars Frequencies: you are screened in advance, there are a maximum of 8 participants, Rosa is present the entire day, and after the ceremony there is integration support. All of those elements determine whether an experience shifts something or stays purely recreational.
The patterns you now recognise, the exhaustion that does not pass, the feeling of not being fully present, these rarely resolve themselves. Iris, three days after her ceremony: "I am completely back at my old energy level, feeling so fit and happy, excited about life again." Thomas B: "It opened a door I thought was closed." An intro call costs nothing and commits you to nothing.
A truffle ceremony is a guided, intentional session with truffles in a safe professional setting. Truffles are legal in the Netherlands. Rosa guides you through a full day with sound healing and breathwork. You work on self-insight and pattern recognition. Stars Frequencies works with small groups of a maximum of 8 people, always with a mandatory intro call beforehand.

Everyone brings something different to the ceremonie. Choose your situation to read how the ceremonie can specifically help you.
Burnout is meer dan vermoeidheid. Het is een signaal van je lichaam en geest dat er iets fundamenteel mis is in de manier waarop je leeft. Een truffelceremonie biedt geen snelle fix — maar wel de ruimte om te voelen wat je al te lang negeert.
Read more✦Trauma leeft in het lichaam. Praten helpt — maar niet altijd genoeg. Een truffelceremonie gaat dieper dan woorden: het werkt op het niveau waar trauma zich verstopt.
Read more✦Angst is geen zwakte — het is een signaal. Maar wanneer angst je leven beheerst, houdt het je klein. Een truffelceremonie helpt je om de angst van binnenuit te onderzoeken, zonder er door meegesleurd te worden.
Read more✦Depressie kleurt alles grijs. Het isoleert, verdooft en steelt de verbinding met het leven. Truffels-assisteerde therapie is een van de meest veelbelovende nieuwe benaderingen van depressie — en we begeleiden je er veilig doorheen.
Read more✦Rouw heeft tijd nodig — maar soms zit het vast. Vastgezet verdriet, onuitgesproken gevoelens, gemiste afscheidswoorden. Een truffelceremonie kan de ruimte bieden om dit los te laten, op jouw manier en in jouw tempo.
Read more✦Soms is er niets 'mis' — maar toch voelt het leven hol. Je hebt het druk, je doet je best, maar je vraagt je af: is dit het? Een truffelceremonie nodigt je uit om dieper te luisteren naar wat je ziel wil.
Read more✦Chronische stress is een sluipmoordenaar. Het systeem staat constant aan — en vergeet hoe het uit moet. Een truffelceremonie met sound healing helpt je zenuwstelsel eindelijk weer te landen.
Read more✦Voor velen is de strengste criticus de eigen innerlijke stem. Zelfliefde is geen gevoel dat je zomaar aan- en uitzet — het is een praktijk. En de ceremonie kan de eerste stap zijn.
Read more✦Verslaving is zelden over het middel zelf — het gaat over de pijn eronder. Truffels-geassisteerde therapie is een van de meest veelbelovende benaderingen voor het doorbreken van hardnekkige patronen en verslavingen.
Read more✦Relaties zijn onze spiegel. Patronen in hoe we verbinden — of vermijden — komen uit onze vroege ervaringen. De ceremonie helpt die patronen te zien en los te laten.
Read more✦Veel mensen leven vooral in hun hoofd. Ze analyseren, begrijpen en redeneren — maar voelen zelden echt. Een truffelceremonie helpt je de brug te slaan tussen denken en voelen.
Read more✦Veel van onze diepste patronen stammen uit de kindertijd. Pijn die we toen niet konden verwerken, leeft voort in ons als volwassene. Een truffelceremonie biedt een veilige ruimte om die jeugdstukken met liefde aan te kijken en te verzachten.
Read more✦De meeste mannen die bij Rosa aankomen, zijn geen strangers van zelfontwikkeling. Ze hebben therapie geprobeerd, gelezen, gepodcast. En toch is er iets wat blijft hangen — een patroon, een spanning, een hoofd dat niet stopt. Een truffelceremonie gaat dieper dan praten. Zonder zweverigheid, met directe begeleiding.
