Jujube fruit, also known as red or Chinese date, is native to Southern Asia but has become popular around the world. These small round fruits with a seed-containing pit grow on large flowering shrubs or trees (Ziziphus jujuba). When ripe, they're dark red or purple and may appear slightly wrinkled. Due to their sweet taste and chewy texture, they're often dried and used in candies and desserts in parts of Asia where they commonly grow. In alternative medicine, they're widely utilized to improve sleep and decrease anxiety.
