Ononis Spinosa is commonly known as spiny restharrow, a species of flowering plant in the legume family. This plant grows widely in Europe, specifically in the Mediterranean region. Its common name "restharrow" comes from its use as a fodder plant, which was frequently cut into small pieces for horses to eat, having been dried and harvested in the summer. Ononis Spinosa is a highly versatile plant, with a number of synonyms including Cammala spinosa, Ononis cornuta, and Ononis eriocarpa, among others. Its leaves are highly prized for their medicinal properties, being used traditionally to treat conditions such as kidney stones, bladder problems, and inflammation.
