Wrigleys Airwaves

Airwaves is a brand of sugarfree chewing gum produced by the Wrigleys. The brand is marketed for its intense flavor. This intensity of flavor is obtained by including Eucalyptus and Menthol in the candy coating of the tablets of gum. This menthol and eucalyptus combination is widely used in medicated sweets to clear the head and nasal passages and to reduce the symptoms of nasal congestions and colds.

Airwaves comes in six flavors: Eucalyptus and Menthol (the blue packets), Blackcurrant and Vitamin C (the purple packets), Cherry (the red packets), Grapefruit and Menthol (the pink packets), Herbal (the light green packets) and the Black Mint (Black Packet).
