Grether’s, originally Allenburys Pastilles, has been handcrafted in Switzerland since 1850. Each lozenge is made following a time-honored recipe using natural fruit essences, glycerine, and agar-agar, then delicately aged in climate-controlled chambers for optimal flavor and texture. Celebrated by vocal professionals and created with Swiss precision, Grether’s offers soothing, high-quality pastilles for voice health and throat comfort.
