Glucocorticoids are steroid hormones that activate the body's stress response, and are used in medicine to treat diseases caused by an overactive immune system, such as allergies, asthma, autoimmune diseases, and sepsis. They can also be used in high doses to treat cancer. Psilocybin, the active ingredient in magic mushrooms, has been shown to have positive effects on mental health conditions such as depression, addiction, and obsessive-compulsive disorder. While glucocorticoids are known to interfere with some medications, there is no evidence to suggest that they interfere with psilocybin. In fact, studies have shown that transient elevation of plasma glucocorticoids supports psilocybin-induced anxiolysis in mice. However, psilocybin can interact badly with other medications, such as antidepressants, anti-convulsants, and anti-epileptic medications.

Psilocybin-induced anxiolysis in mice
In a study by Horita and Weber, the psychoactive compounds psilocybin and psilocin, found in psilocybe mushrooms, were identified and synthesized. The study found that psilocybin-induced glucocorticoid release is a key mechanism for inducing anxiolysis in mice. The results suggested that transient psilocybin-induced plasma glucocorticoid elevations are necessary for generating long-term anxiolytic-like effects. The psilocybin-induced anxiolysis was also observed through repeated handling and injection stress, which was blocked when glucocorticoid receptors were antagonized with mifepristone.
In another study by Hesselgrave et al., it was found that psilocybin induces acute anxiety and changes in amygdalar phosphopeptides independently of the 5-HT2A receptor. This suggests that psilocybin's antidepressant-like behavioral and synaptic actions may be independent of 5-HT2R activation in mice.
The progression from acute anxiogenesis to postacute anxiolysis and the long-term effects of psilocybin on anxiety-like behavior in mice was supported by and sensitive to the temporal profile of plasma glucocorticoids. These findings indicate that repeated measurement of cortisol concentrations in the blood before, during, and after psychedelic exposure could be used as a human biomarker to understand how environmental conditions modify the progression and resolution of biological stress-associated hormonal responses and anxious behavior following psilocybin-assisted therapy.
Furthermore, a study by Madsen et al. found that psychedelic effects of psilocybin correlate with serotonin 2A receptor occupancy and plasma psilocin levels. This suggests that stimulation of 5-HT2AR is a key determinant for the psychedelic experience.
In summary, these studies suggest that psilocybin-induced glucocorticoid release plays a crucial role in inducing anxiolysis in mice, with potential long-term anxiolytic effects. The findings highlight the complex interactions between psilocybin, glucocorticoids, and anxiety-like behaviors, providing valuable insights into the potential therapeutic benefits of psilocybin-assisted therapy.

Psilocybin and antidepressants
Psilocybin, the active ingredient in magic mushrooms, has demonstrated antidepressant properties in patients with major depressive disorder (MDD) and treatment-resistant depression (TRD). However, it is crucial to understand the risks associated with combining psilocybin and antidepressants.
Serotonin Toxicity
The combination of psilocybin and antidepressants has been linked to serotonin toxicity, sometimes referred to as serotonin syndrome. Serotonin syndrome occurs when there is an excessive amount of serotonin buildup in the brain, which can lead to potentially life-threatening symptoms. While psilocybin is generally considered safe on its own, its interaction with other medications can pose serious risks.
A case study published in the Journal of Clinical Psychiatry reported on a 35-year-old woman with a history of MDD, PTSD, and anxiety who was taking a daily regimen of antidepressants and had recently started using psilocybin recreationally. The authors suggested that the combination of psilocybin and her medication cocktail may have contributed to heightened serotonin toxicity risk.
Diminished Psychedelic Effects
There is some evidence that the acute subjective psychedelic effects of psilocybin may be diminished by the use of antidepressants prior to exposure. Psilocybin weakly inhibits the serotonin transporter site that is the target of selective serotonin reuptake inhibitors (SSRIs). However, one double-blind randomized controlled trial found that SSRI administration for 2 weeks did not significantly alter the acute subjective effects of 25 mg of psilocybin.
Psilocybin-Assisted Therapy
Psilocybin-assisted therapy has been proposed as a potential treatment for depression, particularly in cases of treatment-resistant depression. A study by Dr Miller, a professor in the Department of Psychiatry and Health Behavior, found that a single administration of 25 mg psilocybin with psychological support adjunctive to SSRI demonstrated favourable safety and therapeutic efficacy in subjects with TRD. However, larger, comparator-controlled trials are needed to fully understand the impact of chronic antidepressant treatment on the antidepressant effects of psilocybin.
Serotonin Syndrome Risk
Combining two serotonergic agents, such as psilocybin and antidepressants, can increase the risk of serotonin syndrome. Antidepressant users who take magic mushrooms may be at particular risk of serotonin syndrome, especially if they increase their dosage due to the initial lack of effects. Serotonin syndrome can have serious and potentially fatal consequences, including loss of coordination, confusion, drowsiness, respiratory depression, and in severe cases, a slowdown or stoppage of breathing and heart function.

Glucocorticoids and inflammation
Glucocorticoids are widely used for the suppression of inflammation in chronic inflammatory diseases such as asthma, rheumatoid arthritis, inflammatory bowel disease, and autoimmune diseases. They are also used in the treatment of certain leukaemias and in immunosuppressive regimes following organ transplants. Glucocorticoids are one of the most widely prescribed classes of drugs worldwide and are powerful and affordable. They have been used to treat inflammatory diseases for over 70 years.
Glucocorticoids bind to glucocorticoid receptors in the cytoplasm, which then dimerize and translocate to the nucleus, where they bind to glucocorticoid response elements (GRE) on glucocorticoid-responsive genes, resulting in increased transcription of genes coding for anti-inflammatory proteins. The most striking effect of glucocorticoids is the inhibition of the expression of multiple inflammatory genes (cytokines, enzymes, receptors, and adhesion molecules). This is likely due to a direct inhibitory interaction between activated glucocorticoid receptors and activated transcription factors such as nuclear factor-kappa B and activator protein-1, which regulate inflammatory gene expression. Glucocorticoid receptors also interact with CREB-binding protein (CBP), which acts as a co-activator of transcription, binding several other transcription factors that compete for binding sites on this molecule. Glucocorticoids may lead to deacetylation of histone, resulting in tighter coiling of DNA and reduced access of transcription factors to their binding sites, thereby suppressing gene expression.
The use of glucocorticoids is associated with serious side effects, including osteoporosis, metabolic disease, hypertension, dyslipidaemia, insulin resistance/type 2 diabetes mellitus, and an increased risk of cardiovascular disease. These side effects have prompted efforts to identify compounds that can separate the beneficial anti-inflammatory effects of glucocorticoids from their adverse metabolic effects. While there has been some progress in this area, a greater understanding of the mechanisms underlying the anti-inflammatory and immunosuppressive actions of glucocorticoids is needed.
In terms of interactions with mushrooms, one study found that transient elevation of plasma glucocorticoids supports psilocybin-induced anxiolysis in mice. Psilocybin is the main psychedelic component of magic mushrooms and has shown promise as a treatment for depression and other mental disorders. The study found that the anxiolytic-like effects of psilocybin were blunted by pretreatment with a glucocorticoid receptor antagonist or suppression of psilocybin-induced corticosterone elevations. However, it is important to note that this study was conducted on mice, and the mechanistic relationship between psychedelic-associated alterations in plasma glucocorticoid responses and the time course of anxious responsiveness in humans remains unclear.

Glucocorticoids and the immune system
Glucocorticoids are the most widely used class of anti-inflammatory and immunosuppressive agents, regulating fundamental processes in the human body. They control cellular functions such as cell metabolism, growth, differentiation, and apoptosis. They are used to treat a wide range of rheumatic diseases, including rheumatoid arthritis, vasculitis, and connective tissue diseases. Glucocorticoids have also shown promise in treating mental health conditions such as obsessive-compulsive disorder, addiction, and major depressive disorder.
The endogenous glucocorticoids link the endocrine and immune systems, ensuring the proper function of inflammatory events during tissue repair, regeneration, and pathogen elimination. They act by binding to the glucocorticoid receptor (GR), a nuclear receptor of the steroid/thyroid hormone receptor superfamily. However, there are still gaps in our understanding of glucocorticoid-mediated immunoregulation, especially regarding their effects on specific cell types and their key cellular targets in particular disease states.
Studies have shown that glucocorticoids can induce a transcriptional program that impairs TLR signaling by decreasing receptor gene expression and increasing the expression of negative regulators. For example, high doses of glucocorticoids have been found to normalize an interferon-α signature in cells from patients with systemic lupus erythematosus, reducing the production of anti-nuclear antibodies and type I interferon.
Glucocorticoids have both desirable anti-inflammatory effects and undesirable adverse effects. Their strong immunosuppressive, anti-inflammatory, and anti-allergic effects on immune cells, tissues, and organs significantly improve the quality of life for patients with diseases caused by a dysregulated immune system. However, glucocorticoid-related adverse events can be serious and include diabetes mellitus, osteoporosis, and infections.
In summary, glucocorticoids are versatile modulators of the immune system, and their application targets diverse leukocyte populations. While they are indispensable in treating many inflammatory diseases, further research is needed to fully understand their mechanisms of action and potential side effects.

Glucocorticoids and cancer treatment
Glucocorticoids, a class of hormones secreted by the adrenal glands, are commonly used in cancer patients for symptom relief or as part of their anticancer treatment. They have been used in oncology since the 1940s, when they were found to be effective in treating lymphoid tumors. They are also used to manage vasogenic edema and prevent vomiting and allergic reactions associated with cancer therapy. Glucocorticoids can decrease edema in CNS malignancy and reduce pain secondary to cancer.
Glucocorticoids are not considered oncogenes, unlike other steroid hormone receptors. In breast cancer, the estrogen receptor (ER) drives cell growth, proliferation, and metastasis, and the androgen receptor (AR) plays a similar role in prostate cancer. Glucocorticoids work through the glucocorticoid receptor (GR) to arrest growth and induce apoptosis in lymphoid tissue. They are the cornerstone of treatment for lymphatic cancers, although not all patients respond, and dosage is restricted by side effects.
Glucocorticoids can be administered during all three phases of childhood leukemia treatment: remission induction, intensification (consolidation), and maintenance. They are used most intensely during remission induction, with the goal of eliminating greater than 99% of the disease tissue.
Glucocorticoid monotherapy has shown some benefit in breast and prostate cancer. In advanced breast cancer, adding glucocorticoids to other therapies does not change long-term outcomes. In GI cancer, glucocorticoids likely have a neutral effect, and high doses may be detrimental in non-hematologic malignancies. Glucocorticoids may have a harmful effect in lung cancer.
While glucocorticoids are frequently used, indications and dosing regimens are not always evidence-based, and they can have adverse effects, some of which may be life-threatening. Therefore, careful monitoring and assessment of benefits versus harms are crucial to minimize side effects.

Frequently asked questions
Glucocorticoids are steroid hormones that activate the body's stress response. They are part of the feedback mechanism in the immune system, which reduces certain aspects of immune function, such as inflammation.
Adaptogenic mushrooms are not the same as hallucinogenic or "magic" mushrooms and do not act on the mind or perception. Adaptogens are substances that reduce the negative effects of stress on the body.
There is no evidence to suggest that glucocorticoids interfere with adaptogenic mushrooms. However, glucocorticoids are known to interfere with other transcription factors and proteins.
While adaptogenic mushrooms generally have good safety and tolerability, some studies have reported side effects such as dizziness and headaches. Certain populations, such as those with bleeding disorders or pregnant women, should avoid consuming these mushrooms.
It is not recommended to combine adaptogenic mushrooms with other substances without consulting a medical professional. In particular, reishi mushrooms may cause liver toxicity and interfere with blood-thinning or blood-pressure-lowering drugs. Additionally, magic mushrooms should not be combined with certain medications due to the risk of serotonin syndrome and other adverse effects.
