Jujube (Ziziphus jujuba (Z. vulgaris) Rhamnaceae)

Other Names: Red Date, Chinese Date, Common Jujube

Jujube, a low tree reaching 6–8 meters, is common in Mediterranean regions. It has brown, cracked bark, thorny branches, oval furrowed leaves, and yellowish-green flowers in small inflorescences. Its fruit, a drupe with a single pit, is used medicinally.

Parts for Use

Fruits

1. Harvested in September and October when brown, then dried and pitted.
2. Used for decoctions and ground into flour for pasta.
3. Can be combined with soothing herbs like carob and marshmallow.

Ingredients

The fruit’s flesh is rich in mucus with calming effects, along with flavonoids, saponins, and vitamins A, B, and C.

Use in Treatment

In traditional Chinese medicine, jujube is used to restore strength post-illness and for chronic fatigue. It has antibacterial, anti-inflammatory, antipyretic, and antidiabetic properties, potentially modulating immune responses and reducing allergic reactions. Japanese research shows its triterpene oligoglycosides prevent histamine release, aiding inflammation control. Jujube’s calming glycoside, jujuboside, may reduce brain activity linked to insomnia. It soothes hoarseness, voice loss, sore throats, coughs, bronchitis, and diarrhea, especially when combined with herbs like carob or marshmallow. It also reduces excessive sweating, including during sleep.

Cultivation

Grow jujube in well-drained, moist, or dry soil in a sunny spot, protected from severe frosts. Propagate by seeds, shoots, or cuttings.
