Anadenanthera colubrina (also known as Vilca, Huilco, Wilco, Cebil, or Angico) is a South American tree closely related to Yopo, or Anadenanthera peregrina. To make the psychedelic snuff called Vilca (sometimes called cebil), the black beans from the bean pods of these trees are first toasted until the beans pop like popcorn breaking the bean's husk.
