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 5–20 m (16–66 ft) tall and the trunk is very thorny.[1] The leaves are mimosa-like, up to 30 cm (12 in) in length and they fold up at night.[2] In Argentina, A. colubrina produces flowers from September to December and bean pods from September to July.[3] In Brazil A. colubrina has been given "high priority" conservation status.[1]
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".[citation needed]
A. colubrina grows at altitudes of about 315–2,200 m (1,033–7,218 ft) with roughly 25–60 cm (9.8–23.6 in) per year of precipitation and a mean temperature of 21 °C (70 °F). It tends to grow on rocky hillsides in well-drained soil, often in the vicinity of rivers. It grows quickly at 1–1.5 m (3 ft 3 in – 4 ft 11 in) per year in good conditions.[5] The growing areas are often "savannah to dry rainforest." Flowering can begin in as soon as two years after germination.[6]
Gum from the tree can be used in the same way as gum arabic.[7]
Tannin
A. colubrina'stannin is used in industry to process animal hides.[1]
Entheogen
The beans of A. 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; to a much lesser degree DMT and 5-MeO-DMT are also present.[citation needed]A. colubrina has been found to contain up to 12.4% bufotenin.[8]
It is also believed that the ground beans were used as a snuff by the Tiwanaku.[9] There have been reports of active use of vilca by Wichi shamans, under the name hatáj.[10]
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.[citation needed]
Wood
Anadenanthera colubrina trunk
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."[5]
The wood is also reportedly a preferred source of cookingfuel, 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.[1]
