Botanical Description
Anadenanthera colubrina, known as curupaú, cebíl or vilca, is a South American tree in the family Fabaceae growing 5–20 m tall, with a characteristically thorny trunk. The bipinnate, mimosoid leaves can reach 30 cm long and fold up at night. In Argentina, flowers appear from September to December, followed by flat bean pods that ripen through July. The species occurs from Argentina, Bolivia, Brazil, Ecuador, Paraguay and Peru, and is naturalised in Cuba and on Mauritius. It grows on rocky hillsides in well-drained soil, often near rivers, between 315 and 2,200 m elevation in regions receiving 25–60 cm of annual rainfall, with growth rates of 1–1.5 m per year. The seeds contain bufotenin together with smaller amounts of DMT and 5-MeO-DMT, the basis of the plant's long-documented ceremonial use as a snuff.
Cultural & Historical Context
Traditional American Uses
The seeds of Anadenanthera colubrina have been processed into a potent psychoactive snuff known as vilca or cebíl across the southern Andes and adjacent lowlands for several millennia. Bean pods are roasted, ground in a mortar and mixed with calcium hydroxide (slaked lime) or calcium oxide to liberate the active tryptamine alkaloids, principally bufotenin. The earliest clear archaeological evidence consists of puma-bone smoking pipes recovered with A. colubrina beans at Inca Cueva in Jujuy Province, Argentina, dated to about 2130 BC (Torres & Repke, 2006). The Tiwanaku civilization of the Lake Titicaca basin used ground seeds as snuff, and Wari ceremonial deposits at Quilcapampa in southern Peru, excavated between 2013 and 2017, contained vilca seeds combined with molle-based chicha (Biwer et al., 2022). Contemporary Wichí shamans in the Argentine Chaco continue to employ the snuff under the name hatáj (Califano, 1976).
