Ceratonia siliqua (Carob tree, Locust tree)
One hundred fifty years ago carob was so abundant on the lower hills of Lebanon that a whole region was named after it, Iklim Al Kharroub. The carob tree is valuable; it can grow in poor soils, fixes nitrogen, resists drought, and regenerates itself after fires and grazing. The carob pod is valuable; its pulp is high in fiber and protein and is used as a cocoa powder substitute. The carob seed is valuable; it contains a gum, that is used in ice cream making as a natural stabilizer and emulsifier.
