The fruit of the acai palm, a plant found in Central and South America.

Acai berries have a number of antioxidants and fatty acids, and several studies show that the fruit could have anti-aging effects when taken regularly. However, acai berries are comparable to many other fruits in their antioxidant content. Some manufacturers also claim that the acai berry acts as a powerful aphrodisiac; this claim comes from folklore, but there is no scientific evidence to confirm or discredit it.

Acai is considered to be a safe ingredient. It is used in sexual lubricants, massage liquids, and cosmetics for its purported skin-friendly benefits, as an aphrodisiac, or for its pleasing taste and aroma.
