The tree has astringent, expectorant, anti-diarrheal, antiseptic[4] and hemmorage-arresting properties.[5] It is used for its antiseptic properties in southern Brazil.[4] The bark has a high tannin content of 15.0%[6] 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.[7] Parapiptadenia rigida is psychoactive.[8]

Mechanical properties

It has a "Janka Hardness" of 2300-3700 lb.,[12] a parallel "bending strength" of 16900 psi, a parallel "compression strength" of 8500 psi and a density of 720-1199 kg/m³[13][14] at a moisture content of 12-15%. Its modulus of elasticity is 157 801 kg/cm².[15]
