Botanical Description

An Amazonian seed containing high levels of caffeine, traditionally used to sustain energy and alertness.

A climbing woody vine with compound leaves and pear-shaped red capsules that split open to reveal black seeds partly covered by white arils, resembling eyes.

Earliest recorded uses: Documented by Jesuit missionaries in the 17th century, though Indigenous use predates colonization.

Cultural significance: Central to Sateré-Mawé origin mythology; traditionally ground into a stick and grated into drinks.
