Blueberry is the latest refreshing flavor that Grether`s has to offer! The naturally pure juices of fresh blueberries lend these traditional pastilles their stunning color and unforgettable fruity aroma. Classic sugar free pastilles in the golden tin were invented around 300 years ago and today they are still being manufactured by hand in Switzerland according to an old English formula. Recommended for hoarseness, sore throats, raspy voice and dry mouth.
