Rice is known as the grain of life, and is synonymous with food for Asians. In addition to being a staple food and an integral part of social rites, rituals and festivals in almost all Asian countries, it has a medicinal value too, which was clearly recognized by the medicine systems of the region centuries ago. Rice is the main constituent of life-saving oral rehydration solutions (ORS) and has been used for this purpose since time immemorial.
