Jujubae Fructus (ZJF) [called Dazao (大枣) in Chinese], the fruit of Ziziphus jujuba Mill. (ZJ), is utilized as a food and traditional medicine in China. In TCM use, ZJF is traditionally used to treat and nourish the stomach, tonify the spleen, and nourish the blood, as well as for overall nourishing and strength. According to the available literature from 1974 to March 2019, more than 278 compounds have been isolated and identified from ZJ. Local books, papers and dissertations were also searched. The aim of this review was to examine this plant’s traditional uses, botany, phytochemistry, pharmacological effects, toxicity, pharmacokinetics, quality control and economically important uses. In vivo and in vitro scientific investigations have initially confirmed its pharmacological potential by showing anti-inflammatory, antioxidant, antimicrobial, gastrointestinal protective, cardiovascular, neuroprotective, anticancer, anti-HIV, sedative-hypnotic and anxiolytic effects. Bioactive metabolites belonging to different classes are responsible for these activities, including triterpenoid acids, saponins, cyclopeptide alkaloids, flavonoids and neo-lignans, which are considered the characteristic and active components of ZJ. The TCM use of ZJF, including tonifying and replenishing the middle Qi and nourishing the blood to tranquilize, is based on its gastrointestinal protective, cardiovascular, neuroprotective, sedative-hypnotic and anxiolytic properties. Its detoxification effects are attributed to its anti-inflammatory, antiviral, anticancer and antibacterial activities. Moreover, the TCM characteristics of ZJF (sweet flavour; warm nature; and spleen, stomach, and heart meridian effects) support its traditional uses and pharmacological effects. We encourage more studies to further clarify the relationship between modern applications and traditional uses in the future. Furthermore, no one has studied ZJ blossoms, and researchers should allocate more time to the study of ZJ blossoms. Additionally, unsolved problems include the scientific principle of the Chinese material medica processing [CMMP (中药炮制) in Chinese] of ZJF, the molecular mechanisms of the biological activity of ZJ and its other medicinal parts, the overall pharmacokinetics rather than single molecule pharmacokinetics, the efficacy and the toxicology. All of the unsolved problems noted above require further study.
