According to legend, St John the Baptist lived on the locusts (carob bean pods) whilst he preached in the desert. The pods again were life saving during World War Two for the inhabitants of Malta. Used as a weight comparison by the Romans against pieces of gold. Later the purity of gold was established based on the weight as 24 Keration or carob seeds. This evolved into the measurement carat and 24-carat meant the object was pure gold. A healthy substitute for chocolate but highly toxic to dogs.
