Overview

Acai (Euterpe oleracea), pronounced AH-sigh-EE, is a palm tree found throughout South America. Its berries are dark purple and used to make medicine.

Acai contains antioxidants which are thought to protect cells from damage. Acai berries are believed to have more antioxidant content than cranberry, raspberry, blackberry, strawberry, or blueberry. Chemicals in acai might also reduce swelling, lower blood sugar levels, and stimulate the immune system.

People commonly use acai for athletic performance, high cholesterol, erectile dysfunction (ED), obesity, aging skin, metabolic syndrome, and many other conditions. But there is no good scientific evidence to support these uses.
