Lipstick Tree Overview

Traditionally used to make red ink or paint, giving it the name ‘lipstick tree’. Virtually all the ancient Maya scriptures were penned in Annatto juice. Although the fruit of the Annatto tree is inedible, its flowers, and more especially its seedpods, are the most useful parts. Annatto is currently used as a carotenoid-based food colorant used very broadly, especially in the United States. It is used as a dye, insect repellent, sun block and as spice.
