Yopo Seeds (Cebil)
Yopo Anadenanthera Colubrina seeds (Cebil) is a South American tree closely related to Yopo, The beans of Anadenanthera colubrina are used to make a snuff called vilca (sometimes called cebil). The bean pods are roasted to facilitate removal of the husk, followed by grinding with a mortar and pestle into a powder and mixed with a natural form of calcium hydroxide (lime) or calcium oxide. The main active constituent of vilca is bufotenin. Gum from the tree is used medicinally to treat upper respiratory tract infections, as an expectorant and otherwise for cough. A. colubrina can be found in Argentina, Bolivia, Brazil, Ecuador, Paraguay, Peru, Cuba, and Mauritius.
