The seeds of the Cebil tree are full of psychoactive alkaloids: 5-MeO-DMT and bufotenine. The fabrics have a strong hallucinogenic effect: black / white colors and geometric patterns. Cebil effects are often compared to DMT or LSD but then shorter. To use to make a psychedelic snuff or grow a Cebil tree.
