Acerola (Malpighia glabra), also known as Barbados cherry or wild crapemyrtle, is a tropical fruit-bearing shrub or small tree in the family Malpighiaceae, native to the West Indies and northern South America and also cultivated in India. It grows to 3 m tall, with a dense, thorny crown. The leaves are evergreen, simple ovate-lanceolate, 5-10 cm long, with an entire margin. The flowers are produced in umbels of 2-5 together, each flower 1-1.5 cm diameter, with five pink or red petals.

The fruit is bright red, 1.5-2 cm diameter, containing 2-3 hard seeds. It is juicy, often as much sour as sweet in flavor, and one of the highest concentrations in vitamin C and other nutrients. Although resembling a cherry, it is unrelated to the true cherry (Prunus).

Cultivation and uses

The fruit is edible and widely consumed in the species' native area, and is cultivated elsewhere for its high vitamin C content..

In the 1950s, a manufacturer of baby food decided that apple juice was milder for infants than orange juice. The company claimed that a drop of acerola juice in an 8 oz. can of apple juice provided the amount of vitamin C of an equal amount of orange juice.
