[Solved] Why does psilocybin work?

The effect of psilocybin in the body

After ingestion, psilocybin is converted into psilocin, a substance that closely resembles serotonin, an important neurotransmitter in the brain. Psilocin binds to 5-HT2A receptors, which are distributed across the cerebral cortex and the limbic system. As a result, brain activity is temporarily thoroughly revised, and in particular the Default Mode Network (DMN) — the network that drives the ego, self-reflection, and worrying — is dampened.

This temporary 'silence' in the DMN allows us to break free from ingrained thought patterns and automatic emotional responses. It is precisely because of this that people can, during a psilocybin session Gaining insights, feeling a deeper connection, processing trauma, or experiencing a spiritual breakthrough.

Increased neuroplasticity and BDNF

One of the most groundbreaking effects of psilocybin is the increase of neuroplasticity — the brain's ability to adapt, learn, and recover. Psilocybin stimulates the release of BDNF (Brain-Derived Neurotrophic Factor), a molecule that supports the growth of new nerve connections and promotes cell repair.

Thanks to these processes, deep-seated patterns can be released, creating space for behavioral change and emotional recovery — even after just one session.

Emotional processing and insight

During a truffle session or other guided psilocybin experience, emotions are experienced more intensely. Due to the lowered ego, suppressed feelings such as grief, anger, or fear can surface—but also deep love, compassion, and connection. These emotional breakthroughs are not only valuable during the session but can also mark the beginning of lasting change. You can read more about this in the article about emotions and psilocybin.

A participant shares on the Tripforum how, during a high dose of truffles, he was finally able to connect with his grief, which led to acceptance and inner peace. These experiences are described by many as transformative.

Anti-inflammatory effect

In addition to the mental benefits, psilocybin also has a clear physical function, particularly in the area of inflammation. Studies show that psilocybin lowers inflammatory markers such as TNF-alpha, IL-6, and CRP. This makes it potentially relevant for conditions such as depression, post-COVID, autoimmune diseases and chronic inflammation such as Crohn's disease. Read here how psilocybin works as an anti-inflammatory..

Unlike conventional therapy

What distinguishes psilocybin from traditional therapies is the intensity and effectiveness of a single session. Instead of prolonged repetition and talking about problems, psilocybin works by direct contact with the subconscious and the body. According to a forum article about psilocybin versus conventional therapy Many people experience a breakthrough within a few hours that would otherwise take months or years.

Conclusion

Psilocybin works by acting deeply on the brain, the immune system and emotional awareness. Through serotonergic activation, increased neuroplasticity, BDNF production, suppression of inflammation, and letting go of the ego, it opens the door to healing and growth — in a way that conventional therapy rarely offers.

For many people, psilocybin works even better if the experience takes on a spiritual aspect. Spirituality can help to zoom out even more and therefore minimize personal problems.
