Cébil

''Anadenanthera colubrina'' (also known as vilca, huilco, huilca, wilco, willka, curupay, curupau, cebil, or angico) is a South American tree closely related to yopo, or ''Anadenanthera peregrina''. It grows to tall and the trunk is very thorny. The leaves are mimosa-like, up to in length and they fold up at night. In Argentina, ''A. colubrina'' produces flowers from September to December and bean pods from September to July. In Brazil ''A. colubrina'' has been given "high priority" conservation status.

Nomenclature

''Anadenanthera colubrina'' is known by many names throughout South America. In Peru it is known as ''willka'' (also spelled ''wilca,'' ''vilca'' and ''huilca'') which in the Quechua languages means "sacred".

Geography

''A. colubrina'' is found in Argentina, Bolivia, Brazil, Ecuador, Paraguay, Peru, Cuba, and Mauritius.

Natural growing conditions

''A. colubrina'' grows at altitudes of about with roughly per year of precipitation and a mean temperature of . It tends to grow on rocky hillsides in well-drained soil, often in the vicinity of rivers. It grows quickly at per year in good conditions.Desiccation and storage of Anadenanthera colubrina beans.

General uses

Food

A sweetened drink is made from the bark.

Gum

Gum from the tree can be used in the same way as gum arabic.

Tannin

''A. colubrina's'' tannin is used in industry to process animal hides.

Hallucinogen

The beans of ''A. colubrina'' are used to make a hallucinogenic 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; to a much lesser degree DMT and 5-MeO-DMT are also present. ''A. colubrina'' has been found to contain up to 12.4% bufotenin.

It is also believed that the ground beans were used as a snuff by the Tiwanaku.Hallucinogens Found in Mummy Hair
/ref> There have been reports of active use of vilca by Wichi shamans, under the name ''hatáj''.

Between 2013 and 2017, archaeological excavations at the Quilcapampa site in southern Peru, found that the Wari used seeds from the vilca tree and combined the hallucinogenic drug with chicha, or beer made from the molle tree.

Archaeological evidence shows ''Anadenanthera colubrina'' beans have been used as hallucinogens for thousands of years. The oldest clear evidence of use comes from pipes made of puma bone (''Felis concolor'') found with ''A. colubrina'' beans at Inca Cueva, a site in the Humahuaca gorge at the edge of the Puna of Jujuy Province, Argentina. The pipes were found to contain the hallucinogen DMT, one of the compounds found in ''Anadenanthera'' beans. Radiocarbon testing of the material gave a date of 2130 BC, suggesting that ''Anadenanthera'' use as a hallucinogen is over 4,000 years old. Snuff trays and tubes were found in the central Peruvian coast dating back to 1200 BC. Archaeological evidence of insufflation use within the period 500-1000 AD, in northern Chile, has been reported.

Traditional medicine

The tree's bark is the most common part used medicinally. Gum from the tree is used medicinally to treat upper respiratory tract infections, as an expectorant and otherwise for cough.Plantamed (Portuguese)

Wood

In northeastern Brazil, the tree is primarily used as timber and for making wooden implements. "It is used in construction and for making door
and window frames, barrels, mooring masts, hedges, platforms, floors,
agricultural implements and railway sleepers."
The wood is also reportedly a preferred source of cooking fuel, since it makes a hot and long-lasting fire. It is widely used there in the making of fences, since termites seem not to like it. At one time, it was used in the construction of houses, but people are finding it more difficult to find suitable trees for that purpose.
