Originated about 4,000 years ago in China, the Jujube fruit is considered a must-have in the daily Chinese dietary. The Jujube fruit contains up to 20 times more vitamin C than any citrus fruit. In addition, it is rich in Vitamins A, B1 and B2, as well as calcium. Its nutrients deliver intense moisture, nourishment and protection to the outer skin layers as well. Jujube fruit is an antioxidant with rejuvenating properties. You can use it to treat skin inflammation and skin irritation such as eczema, acne and psoriasis.
