Ziziphus mauritiana is a major commercial fruit-producing species in India with many cultivars varying in fruiting season and in fruit form, size, color, flavor, and keeping quality. The fruit is rich in vitamin C and is eaten raw, pickled, or used in beverages.
The illegitimate name Ziziphus jujuba (Linnaeus) Gaertner is sometimes used for this species.
