jujube: see buckthorn.
Ziziphus zizyphus (from Greek ζίζυφον - zizuphon, syn. Z. jujuba, Rhamnus zizyphus), commonly called Jujube, Red Date (紅棗), or Chinese Date, is a species of Ziziphus in the buckthorn family Rhamnaceae, used primarily for its fruits.

Its precise natural distribution is uncertain due to extensive cultivation, but is thought to be in southern Asia, between Syria, northern India, and southern and central China, and possibly also southeastern Europe though more likely introduced there.

It is a small deciduous tree or shrub reaching a height of 5-10 m, usually with thorny branches. The leaves are shiny-green, ovate-acute, 2-7 cm long and 1-3 cm broad, with three conspicuous veins at the base, and a finely toothed margin. The flowers are small, 5 mm diameter, with five inconspicuous yellowish-green petals. The fruit is an edible oval drupe 1.5-3 cm long; when immature it is smooth-green, with the consistency and taste of an apple, maturing dark red to purplish-black and eventually wrinkled, looking like a small date. There is a single hard stone similar to an olive stone.


The species has a curious nomenclatural history, due to a combination of botanical naming regulations, and variations in spelling. It was first described scientifically by Carolus Linnaeus as Rhamnus zizyphus, in Species Plantarum in 1753. Later, in 1768, Philip Miller concluded it was sufficiently distinct from Rhamnus to merit separation into a new genus, in which he named it Ziziphus jujube, using Linnaeus' species name for the genus but with a probably accidental single letter spelling difference, 'i' for 'y'; for the species name he used a different name, as tautonyms (repetition of exactly the same name in the genus and species) are not permitted in botanical naming. However, because of Miller's slightly different spelling, the combination correctly using the earliest species name (from Linnaeus) with the new genus, Ziziphus zizyphus, is not a tautonym, and therefore permitted as a botanical name; this combination was made by Hermann Karsten in 1882.

Cultivation and uses

Jujube was domesticated in the Indian subcontinent by 9000 BCE. Over 400 cultivars have been selected.

The tree tolerates a wide range of temperatures and rainfall, though it requires hot summers and sufficient water for acceptable fruiting. Unlike most of the other species in the genus, it tolerates fairly cold winters, surviving temperatures down to about -15°C. This enables the jujube to grow in desert habitats, provided there is access to underground water through the summer. Virtually no temperature seems to be too high in summertime.

Medicinal use

The fruits are used in Chinese and Korean traditional medicine, where they are believed to alleviate stress. The jujube-based Australian drink 1-bil avoids making specific stress-related claims, but does suggest drinking 1-bil "when you feel yourself becoming distressed".

Ziziphin, a compound in the leaves of the jujube, suppresses the ability to perceive sweet taste in humans. The fruit, being mucilaginous, is also very soothing to the throat and decoctions of jujube have often been used in pharmacy to treat sore throats.

Culinary use

The freshly harvested as well as the candied dried fruits are often eaten as a snack, or with tea. They are available either red or black (called hóng zǎo or hēi zǎo, respectively, in Chinese), the latter being smoked to enhance their flavour In mainland China, Korea, and Taiwan, a sweetened tea syrup containing jujube fruits is available in glass jars, photo and canned jujube tea or jujube tea in the form of teabags is also available. Although not widely available, jujube juice and jujube vinegar photo (called or 红枣 in Chinese) are also produced.

In China, a wine made from jujubes called hong zao jiu (红枣酒) is also produced. Jujubes are sometimes preserved by storing in a jar filled with baijiu (Chinese liquor), which allows them to be kept fresh for a long time, especially through the winter. Such jujubes are called jiu zao (酒枣; literally "spirited jujube"). In Korea, jujubes are called daechu (대추) and are used in teas. It is said to be helpful in aiding the common cold.

In addition, jujubes, often stoned, are a significant ingredient in a wide variety of Chinese delicacies. In Persian cuisine, the dried drupes are known as annab.

Other uses

The jujube's sweet smell is said to make teenagers fall in love, and as a result, in the Himalaya and Karakoram regions, men take a stem of sweet-smelling jujube flowers with them or put it on their hats to attract women.

In traditional Chinese wedding ceremony, jujube and walnut were often placed in the newlyweds' bedroom as a sign of fertility.

In Japan, the natsume has given its name to a style of tea caddy used in the Japanese tea ceremony.

In Korea, the wood is used to make the body of the taepyeongso, a double-reed wind instrument.

In Bhutan, the leaves are used as a popuri to help keep the houses of the inhabitants smelling fresh and clean. Also It is said to keep bugs and other insects out of the house and free of infestation.

Pests and diseases

Witch's brooms, prevalent in China and Korea, is the main disease affecting jujubes, though plantings in North America currently are not affected by any pests or diseases.
