Key Biological Features

• Natural Synthesis: Over 180 species naturally synthesize psilocybin, primarily within the Psilocybe genus (including native UK species like Psilocybe semilanceata / Liberty Caps).

• Metabolic Conversion: Psilocybin is a prodrug. Upon ingestion, dephosphorylation removes a phosphate group to convert the compound into active psilocin, which crosses the blood-brain barrier.

• Receptor Affinity: Psilocin acts as an agonist at serotonin 5-HT2A receptors, temporarily altering neural connectivity across the brain’s Default Mode Network (DMN).
