Psychedelic mushroom
Psilocybin mushrooms', also known as 'Psychedelic mushrooms', contain the alkaloid psilocybin and other related tryptamine derivatives. Psilocybin changes certain things in the brain. This leads to the nerve cells giving more signals - generally translated to a different consciousness. This can lead to effects like hallucinations or visions. They can also be used for medical purposes to treat cluster headaches, obsessive-compulsive disorder, and certain kinds of depression.
