Ziziphus spina-christi, known as the Christ's thorn jujube, is an evergreen tree or plant native to northern and tropical Africa, Southern and Western Asia. It is native to the Levant, East Africa and some tropical countries. Fruit and leaves from the tree have been used in Ancient Egyptian food and medicine. Modern research has shown that compounds extracted from the tree's leaves could be used to decrease severe inflammation. Additionally, honey from bees that feed on the tree's nectar has anti-bacterial properties that inhibit infectious diseases, especially when compared to other types of honey.
