The plant
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. The leaves are mimosa-like, up to 30 cm (12 in) 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.
Use
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. 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. 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.
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.
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.
