It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America. The generic name is derived from the Greek words θεός ("theos"), meaning "god," and βρῶμα ("broma"), meaning "food". It translates to "food of the gods."

Cacao is commercially valued as the source of

This is equally true of abandoned cultivated trees, making it difficult to distinguish truly wild trees from those whose parents may originally have been cultivated.

Ceramic vessels with residues from the preparation of cacao beverages have been found at archaeological sites dating back to the Early Formative (1900–900 BC) period. For example, one such vessel found at an Olmec archaeological site on the Gulf Coast
