Biological Action of Psilocybin
Psilocybin, though a naturally occurring chemical substance, induces complex psychoactive effects through interaction with serotonin receptors in the human brain. The mechanism of its action has been thoroughly studied, yet there remains much to be discovered.
A. Mechanism of Action in the Brain:
Psilocybin is a prodrug, which in the human body converts into psilocin, the active chemical compound. Psilocybin primarily interacts with type 2A serotonin receptors (5-HT2A) in the cerebral cortex, leading to changes in sensory and emotional processing.
B. Interactions with Serotonin Receptors:
Stimulation of 5-HT2A receptors causes increased release of neurotransmitters, including serotonin, dopamine, and glutamate. These neurochemical changes lead to disruptions in normal information processing, which may be the cause of the psychedelic hallucinations and alterations in the perception of reality experienced.
C. Research on Neurochemical Effects:
Modern neuroimaging techniques allow for the observation of changes in brain activity under the influence of psilocybin. Clinical and experimental studies are also conducted to understand the impact of psilocybin on neural networks and neuroplasticity.
Research into the biological mechanisms of psilocybin’s action is crucial for a better understanding of its therapeutic potential as well as potential risks associated with its use. In the latter part of the article, we will discuss the physiological effects of psilocybin both in the short and long term.
Physiological Effects of Psilocybin
Psilocybin, being a potent psychoactive substance, induces a variety of physiological effects both in the short and long term. Understanding these effects is crucial for assessing its potential impact on the human body and for the development of therapies based on its action.
A. Short-term effects: Hallucinations:
One of the most characteristic psychoactive effects of psilocybin is intense hallucinations. These hallucinations can include changes in the perception of colors, shapes, sounds, and profound sensory experiences.
Changes in the perception of time and space:
Psilocybin can lead to changes in the sense of time, which may become blurred or elongated. The perception of space may change, leading to feelings of expansion or compression of space. Emotional experiences:
Experiences under the influence of psilocybin can be deeply emotional and filled with profound feelings. These may include feelings of euphoria and happiness, as well as anxiety or distress. B. Long-term effects: Potential therapeutic benefits:
An increasing amount of research points to potential therapeutic benefits of psilocybin in treating various mental disorders, such as depression, anxiety, or PTSD. Psychedelic therapy, utilizing psilocybin as a therapeutic tool, is gaining increasing popularity and recognition in the scientific community.

Despite promising research results on psychedelic therapy, there are concerns regarding the misuse of psilocybin and its potential impact on the mental and physical health of users. Further research is needed to understand the long-term effects of its use and to assess the risk associated with its usage. Studying both the short- and long-term effects of psilocybin is a crucial step in understanding its impact on the human body and in the development of new therapies based on its action. In the next part of the article, we will look at the use of psilocybin in therapy and the current clinical studies on its potential medical applications.
Physiological Effects of Psilocybin
Psilocybin, despite its potent psychoactive effects, is gaining increasing attention due to its potential therapeutic applications. Clinical studies and observations from psychedelic therapy suggest that this substance can be an effective tool in treating various mental and emotional disorders.
A. Clinical Studies:
Depression:
Research suggests that psilocybin can be effective in treating depression that is resistant to other therapies.
This substance can lead to profound emotional experiences that help patients see their lives from a new perspective.
Anxiety and anxiety disorders:
Psilocybin shows potential in treating anxieties and anxiety disorders, providing relief to patients experiencing anxiety and distress.
PTSD:
Studies indicate the possibility of using psilocybin in therapy for individuals suffering from PTSD, especially those who do not respond to traditional therapies.
B. Psychedelic Therapy:
Therapeutic Process:
Psychedelic therapy involves the use of psilocybin during a controlled psychedelic experience, conducted under the supervision of a therapist.
Patients are encouraged to explore their inner experiences and emotions, which can lead to deep self-work and psychological transformation.
Potential Benefits:
Psychedelic substances like psilocybin, LSD, or MDMA have been studied for their ability to induce profound, often transformative psychological experiences, which can help patients look at their lives and the problems they face in a new way. One aspect of psychedelic therapy is the potential for deep self-understanding. Under the influence of psychedelic substances, patients often experience phenomenal states of consciousness that can unlock hidden memories, thoughts, or emotions. Such experiences can lead to new perspectives on one’s life, relationships, or issues, which are immensely valuable in the therapeutic process. Psychedelic substances can help reduce defensive mechanisms and offer the opportunity for direct confrontation with difficult emotions.
Improvement in Well-being and Quality of Life
Long-term studies indicate that positive changes in well-being and quality of life initiated by psychedelic therapy can persist for a long time after the therapy ends. Patients often report improved mood, increased empathy, and openness to experiences, as well as reduced depressive symptoms. These changes can lead to better coping in daily life and improved interpersonal relationships.
C. Examples of Uses in Treating Mental Disorders:
An increasing number of studies and clinical reports emphasize the potential of psilocybin in treating a variety of mental disorders, from depression and anxieties to addictions and obsessive-compulsive disorders. Although still in the research phase, psychedelic therapy could bring revolutionary changes in the approach to treating mental disorders.
Clinical studies and observations from psychedelic therapy indicate potential benefits of using psilocybin in treating various mental disorders. However, further research is necessary to fully understand the mechanisms of action of this substance and to assess its effectiveness and safety in the long term.
Safety and Potential Risks
Despite promising research results on the therapeutic potential of psilocybin, there are also serious concerns regarding its safety and potential negative effects. Understanding these aspects is essential for the proper assessment of the risk associated with its use and for developing appropriate protocols and clinical guidelines.
A. Safety of Use Under Supervision:
Controlled Environment:
The use of psilocybin in therapy should take place in a controlled clinical environment under the supervision of experienced medical staff.
Emphasis on the Importance of Set and Setting:
The setting and the patient’s state of mind (set) are crucial for the course of psychedelic therapy and minimizing the risk of negative reactions.
B. Potential Adverse Effects:
Mental Disorders:
Psilocybin can induce intense emotional and cognitive experiences, which in some individuals may lead to the exacerbation of existing symptoms of anxiety and depression. For individuals with a history of mental disorders, even a single use of psilocybin can intensify negative thoughts and emotions, which can be particularly challenging to manage without appropriate medical and therapeutic support. Individuals with genetic predispositions or personal history of psychotic disorders, such as schizophrenia, are especially at risk of triggering psychotic episodes after taking psilocybin. Psychedelics can cause temporary states similar to psychosis, which for those predisposed may turn into permanent episodes.
Mental Deficiencies:
In cases of excessive use of psilocybin, symptoms such as disorientation, disorganized thinking, and loss of reality awareness may occur.
Physical Reactions:
Psilocybin can also cause physical reactions, such as nausea, vomiting, muscle tremors, and increased heart rate.
