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 BrazilA. 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 which in the Quechua languages means "sacred".
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. The growing areas are often "savannah to dry rainforest." Flowering can begin in as soon as two years after germination.
The beans of A. colubrina are used to make a snuff called vilca. 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 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 grounded 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.
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.
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 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.
