Origin and history
Annatto, also known as urucum or achiote , is a small tree native to the tropical regions of South America. Used for millennia by the Amazonian peoples, it served as a natural dye , sunscreen , and traditional remedy . Even today, Amazonian Indians coat their bodies with its red paste to protect themselves from insects and the sun. Discovered by European explorers in the 16th century, annatto quickly spread throughout the world due to its richness in beta-carotene and antioxidants .
