Quassia amara

Quassia amara, also known as amargo, bitter-ash, bitterwood or hombre grande, is a species of small evergreen shrub or tree in the family Simaroubaceae, native to Central and South America including Trinidad and Tobago, Costa Rica, Nicaragua, Panama and the Amazon basin countries. It grows up to 6 meters tall with distinctive red flowers and dark green leaves, and every part of the plant contains bitter compounds, chiefly quassin. It is used as a natural insecticide, as a flavoring agent such as in Angostura Bitters, and in traditional medicine for malaria, diabetes and parasitic infections.
