Chios mastic, in contrast to common chewing gums, due to its peculiar taste and relative hardness, causes a greater stimulation of saliva, resulting in an increase in the sensation of freshness and cleanliness in the mouth, while at the same time contributing to the soothing treatment of dry mouth.
Chios mastic is a key ingredient of ELMA chewing gum. It is a natural resin known in ancient times to the peoples of the Eastern Mediterranean, who chewed it to have clean teeth and fresh breath. It was the first natural chewing gum of the ancient world.
