Cumarú is a well-known tree, that is especially valuable because of the various medical properties of its tonka bean seeds. The glycoside Cumarin found in them is used (in some countries under strict conditions) as a scent and aromatic substance in perfumery.


Botanical name: Dipteryx odorata
Overall character: This wood has a simple and modest look. Its color and structure are usually homogenous, with a medium texture and particularly high density. The alternating spiral growth causes a glossy appearance.
Color and structure: Fresh heartwood is a yellowish-red to violet-brown. It later turns into yellowish brown to olive brown, frequently with streaks of color. It is mostly contrasts from the narrow, yellowish white to light brown splint.
Characteristics/features: Due to the very good resistance to wood-discoloration and wood-destroying fungi and insects, untreated Cumaru can be used for long-term outdoor use.
Areas of use: Used as a construction wood in outdoor areas for applications that are highly strained mechanically and biologically, and that do not require high dimensional stability. Areas of use include bridges, sleepers, floating docks, locks and hydraulic engineering (safe only in fresh water!).
