Morphology

This species typically grows as a small tree or erect shrub, characterized by its sturdy branches and pinnately compound leaves. The leaflets are arranged alternately along the rachis, exhibiting a smooth, slightly leathery texture that helps conserve moisture under the forest canopy.

Its reproductive structures and features include:

  • Inflorescences: Elongated racemes bearing small, pale flowers with narrow petals.
  • Fruits: Small drupes that contain highly bitter, almond-like seeds.
  • Wood: Light-colored and lightweight, containing active bitter principles.

Applications

The primary application of this species lies in traditional medicine and ethnobotany. Indigenous groups in Colombia and Panama have historically utilized the seeds to treat various ailments, most notably as an antidote for venomous bites and fevers.

Other documented uses include:

  • Digestive Aid: Infusions made from the bark or seeds have been used to alleviate stomach pain.
  • Insecticide: The natural bitterness acts as a deterrent, prompting investigation into organic pest control.

Interesting facts

During the 19th century, the seeds of this plant gained international fame under the name Haba de Cédron. European explorers and researchers eagerly sought them out, believing they possessed near-miraculous healing powers against malaria.

The extreme bitterness is caused by quassinoids, which are among the most bitter natural substances known to science.
