HOw DOEs PSILOcybin WORk?

In our ceremonies, we offer our signature tea made from legal truffles containing natural psilocybin. This induces a psychedelic experience of approximately 4-6 hours.

Dosages are determined in consultation with each individual participant and based on your experience, intention and current physical and mental condition.

After ingestion, Psilocybin is metabolised by our bodies into Psilocin, which is responsible for inducing the psychedelic state. Its molecular structure fits precisely into one specific serotonin receptor (5HT2A).

What is serotonin?
Serotonin, like dopamine, is a neurotransmitter. It’s sometimes referred to as the “happiness” or “feel good” molecule. It practically controls all human behavioural processes and plays a dominant role in the Central Nervous System.

What is neuroplasticity?
Thoughts and habits create neurological pathways in the brain. When we repeat a particular habit or thought, this pathway gets ingrained in the mind. The longer, the deeper, sometimes even to the point that we think there’s no other option.

Neuroplasticity is the ability of the brain to form new connections. New connections can mean new insights, ideas and perspectives on an existing problem or observation.

A psychedelic experience can create a window of time where there is an opportunity to rearrange or reroute some of these pathways. This can enable you to replace habits and thought patterns that may no longer be beneficial to you.

FrequENTLY ASKED questioNS

  • Psychedelics improve the brain’s neuroplasticity, which can be helpful in breaking thought patterns and replacing old habits with more beneficial behaviour. It allows you to gently and calmly open up to thoughts and feelings that you may avoid in everyday life. You may feel a deeper connection with yourself, allowing you to address a wide range of issues in your life. Psychedelic journeying is most useful when supported by the program and practices we offer in our app.

  • Psychedelic plants and fungi have been used in indigenous medicinal traditions for thousands of years. The scientific world has studied the benefits of truffles since the 1950’s and has repeatedly reported positive effects on behavior, cognition, spirituality and consciousness. As scientific research continues, promising results are made in neuroscience, mood and mental disorders, addiction and habit formation.

  • There are two main considerations when taking psychedelics: your physical and mental health and the timing in your life. If you are receiving treatment or taking medication, please consult your doctor. As for timing, trust your intuition. Do you have enough time and space in your life? Are you in a balanced and open state of mind? The tools we offer, like our Psychedelic Masterclass, are designed to help you create the optimal conditions for mind and body.

  • Your experience and the longevity of its benefits will likely improve if you’re well prepared. Our Psychedelic Masterclass offers a variety of practices to create the right mindset and environment for a meaningful and safe journey. We will give you detailed practical information on dietary recommendations and help you find peace of mind through meditative practices and breathwork.

  • Psilocybin is safe when used responsibly in a safe environment with people you know and trust. It is a naturally occurring substance that is converted by the body into psilocin, which acts on the serotonin receptors in the brain. Psilocybin is not addictive and there are no known reports of overdoses. We advise you to conduct your own research as well and to consult various sources of information.

  • Fresh truffles containing natural psilocybin are legal to buy and consume in the Netherlands. Unfortunately, this is not the case in most countries around the world. However, you can still enjoy the benefits of our Transformation Box and educational platform even if your country has not yet legalised truffles containing natural psilocybin. Unfortunately, we can not ship our truffles, but we have an international option with a nice surprise.

  • In general this is a high dose ceremony. Meaning: 21 grams of fresh truffles. However, we will check in with you and can change the dosage accordingly.

  • Our Sclerotia Psilocybe are 100% natural, unprocessed and free of additives. Do not consume if you are under 25 years of age, pregnant or breastfeeding. Do not take in combination with alcohol, drugs or medication or while driving. Please consult your doctor beforehand if you have a mental and/or medical condition. Read more in our protocol above.

  • Do not consume psilocybin when you take any medication. Always consult a doctor before you take any further steps. If you have any specific questions, we can also consult our medical expert for this.
  • (PLEASE CONSULT A DOCTOR WHEN IN DOUBT) There are a few important contra-indications, such as if you are suffering from heart problems, if you are currently dealing with mental issues, or when you are pregnant.
