Jujube can be divided into north jujube and south jujube according to geographical distribution. North jujube has high sugar content and low water content, and is mostly used for drying jujube. Nanzao has a low sugar content and a lot of water, and is mostly used for processing candied dates. China has the best varieties produced in Henan and Shandong. In addition, there is also a kind of Zizyphus jujuba, which is a variety of jujube. The fruit is spherical, small, with thin pulp, large core, sweet and sour taste and extremely rich in ascorbic acid.

Jujube fruit is one of the oldest medicinal and beauty fruits in China. "Compendium of Materia Medica" says that jujube: "tonify the middle energizer, nourish the spleen, moisten the heart and lungs, regulate Wei Rong, slow down yin and blood, promote body fluid and delight the color". There is a folk saying that "three jujubes a day is too few to live to ninety-nine", and the efficacy of jujube can be seen from this. According to research, jujube is rich in nutrition, containing more sugar, fat, protein, starch, vitamins, carotene, tannin, nitrate, organic acids, phosphorus, calcium, iron and other components. Especially dried dates, the sugar content is as high as 50%; The vitamin C content of jujube is the first finger in fruits, which is about 100 times higher than that of apples and peaches. The content of vitamin P is also the highest among all fruits, so it has the reputation of "natural vitamin pills". Studies have found that jujube can promote the synthesis of protein, increase the body's resistance, and have the functions of sedation, blood pressure reduction, antiallergic and cancer cell inhibition.
