The annatto tree seeds contain an alimentary orange-red coloring substance utilized in Mexico even before Spanish colonization. Also, the fruit of this tree is used as a seasoning, and its bark provides a textile fiber.

The Mayans and the Aztecs used the annatto tree to treat leprosy, who had notable phytotherapeutic knowledge. Presently, we know that this tree shares botanical and chemical similarities with the Hydnocarpus kurzii [King] Warb. ( = Tarakogenos kurzii King), an Asian tree from which a certain oil is extracted, used today to treat leprosy.
