Zizyphus (Ziziphus jujuba) is a thorny shrub. The fruit is edible and looks similar to a date. It's rich in fiber, vitamin C, B vitamins, and fatty acids.
Zizyphus contains chemicals that might lower sugar and fat levels in the blood, and also cause sleepiness.
People use zizyphus for constipation, diabetes, aging skin, high cholesterol, insomnia, and many other conditions, but there is no good scientific evidence to support these uses.
Is It Effective?
