Parapiptadenia rigida is a perennial shrub or tree. It is not a threatened species. It is native to Argentina, Brazil, Paraguay and Uruguay. Common names include angico, angico-cedro, angico-do-banhado, angico-dos-montes, angico-verdadeiro, angico-vermelho (in Spanish angico is changed for anchico), guarucaia and paric.[2]
Parapiptadenia rigida grows from about 18m to 30m in height and it has a straight trunk which has slightly furrowed bark. The foliage is dark green and the flowers are greenish-yellow 5 cm to 9 cm long. It blooms in the spring. The seed pods grow 9 cm to 16 cm in length. The seeds are flat, oval and brown. It is found along the lengths of rivers.
Essential oils from the tree are becoming more widely recognized in industrial fragrance production.[3]
Gum from the tree can be used in the same way as gum arabic.[4]
Extracts from the tree have astringent, expectorant, anti-diarrheal, and hemorrhage-arresting properties.[5] It is used for its antiseptic properties in southern Brazil.[6] The bark has a high tannin content of 15.0%[7] and it is used in folk medicine as a bitter-tasting tonic and body cleanser. It is used to treat rickets, lack of appetite and muscle weakness.[8] Parapiptadenia rigida is psychoactive.[9]
The tree's bark contains 15.0% tannin.[10]
Its dense, wood is resistant to the elements and is used for construction,[11] carpentry, beams for bridges,[8] poles and firewood.[12] The wood is said to be unaffected by insects including termites and it can last more than 20 years unpainted.
It has a "Janka Hardness" of 2300-3700 lb.,[13] a parallel "bending strength" of 16900 psi, a parallel "compression strength" of 8500 psi and a density of 720–1199 kg/m3[14][15] at a moisture content of 12-15%. Its modulus of elasticity is 157 801 kg/cm2.[16]
For hardwood flooring it is called "pepperwood."[13]
