Extracts from the tree have astringent, expectorant, anti-diarrheal, and hemorrhage-arresting properties.[citation needed][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.[citation needed] It is used to treat rickets, lack of appetite and muscle weakness.[8] Parapiptadenia rigida is psychoactive.[9][verification needed]

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.

Mechanical properties[edit]

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]
