About Jujube Tea:
While they may not have a large amount of any one nutrient, jujubes contain a wide array of different ones, including magnesium, potassium, copper, niacin, calcium, manganese, phosphorus, and iron. They contain 20 times more vitamin C than any citrus fruit, strengthening the immune system and fighting infections, which may be why they've been used medicinally for millennia in many cultures, as a tea for sore throat, for example.
Medical studies have found that jujube fruits and extracts have the capacity help lower blood pressure,keep from liver disease, treat anemia, and inhibit the growth of tumor cells that can lead to leukemia. Jujube extracts are also used in skin care products used to diminish wrinkles, relieve dry skin, and treat sunburn pain.
How one fruit can have all these  has to do with not just the combination, but also the complexity of its phytonutrients. Scientists have identified eight flavonoids in jujube fruit, including spinosin and swertish, which have sedative properties – undoubtedly the reason jujube seeds are used to treat anxiety and insomnia in traditional Chinese medicine.

Jujubes are also loaded with 18 of the most important amino acids, which aids in the formation of more than 50,000 proteins in the body, one of which triggers the wound-healing process.
Dried jujubes contain more carbohydrates, but have less fiber than fresh ones. They are much higher in calories, although they are more nutritious and an excellent source of energy.
However, consume jujubes in moderation because they contain fructose, which may be harmful to your health in excessive amounts.
