Angostura trifoliata is a shrubby tree native to northern South America. In Venezuela, it grows in mountainous areas at an altitude of between 200 and 300 m above sea level.
Formerly, angostura bark was believed to be the bark of Cusparia trifoliata Engl. (syn. C. febrifuga Humb.), a tree related to Galipea officinalis reported to grow in Brazil. (Related species found in Brazil include Galipea dichotoma Sald. and G. multiflora Schult. ) Much of the scientific literature before 1960 was based on this species.
