This review examines how the body processes psilocybin, a compound from magic mushrooms being studied for treating depression and anxiety. When taken orally, psilocybin is quickly converted to its active form, psilocin, which reaches peak levels in the bloodstream within 1-4 hours and is eliminated mainly through urine. The body’s ability to process psilocybin involves specific liver enzymes that vary between individuals, potentially explaining why people respond differently to the same dose and why certain medications can interfere with its effects.
