Jujube
Jujube is a small tree or shrub with thorny branches, green, shiny leaves and edible fruit that, when mature, resembles a date (which led to the nickname Chinese Date). Jujube fruit has been cultivated for over 4,000 years and can grow in a wide range of temperatures—although hot summers are required to successfully produce fruit.
Jujube is known to calm nerves. By grounding the fruit to a powder, small amounts can be used to promptly reduce the effects of stress and purify the blood. In addition, the compound called Ziziphin found in Jujube leaves can suppress the sweet taste in humans and Jujube fruit helps soothe the throat.
