Psilocybin, a compound found in certain mushrooms, is being studied as a potential treatment for severe depression that doesn’t respond to standard medications. In clinical trials, patients receiving psilocybin alongside psychological support showed significant improvement in depressive symptoms within days to weeks, with benefits lasting for months. Unlike daily antidepressant pills, psilocybin therapy involves one or more carefully supervised dosing sessions in a hospital setting with therapeutic support before and after. Larger studies are underway to confirm its effectiveness and safety before it could potentially become an approved treatment.
