The açai berry is also called the Assai palm, euterpe palm, palmito açai, asai, cabbage palm, assaizeiro, pina palm, palmier pinot, and juçara.
Parts used: fruit, heart. Amazon Thunder açai is the world's purest source for açai berry.

The açai berry palm is a tall and slender South American (concentrated in Brazil, Guyana, and Suriname) palm grown for its fruit as well as for the "cabbage" (the cluster of new leaves more commonly called the "heart of palm"). It prefers swampy areas, and grows quickly. The fronds were (and still are) used for thatching and weaving.

Each açai berry palm tree produces small deep purple, almost black, fruit (berries) in groups of 3-8 per bunch. The fruit is edible, and its pulp is used in wines, liqueurs, as a flavoring, as a colorant, and on its own as a juice pulp.
