. The wood is flexible and durable. The tree is also used as an ornamental tree in landscaping. The fast growth and high reproduction rate allows this species to be used for the recovery of degraded areas.

Extracts from the tree, known as "ipê-preto", are used locally as medicine for cancer and skin-diseases. Laboratory tests have shown antimicrobial properties in these extracts, but due to concerns about toxicity no clinical applications have been utilized.
