The mushroom known for its psychoactive properties is the Psilocybe cubensis, commonly referred to as "magic mushrooms." These mushrooms contain the naturally occurring compound psilocybin, which is responsible for their hallucinogenic effects. When ingested, psilocybin converts to psilocin in the body, leading to altered perceptions, mood changes, and visual or auditory hallucinations. While they have been used traditionally in spiritual and religious contexts by indigenous cultures, magic mushrooms have gained popularity in modern times for their therapeutic potential, particularly in treating mental health disorders such as depression and PTSD. Research is ongoing to understand their effects and potential uses in medicine.
