Grether's pastilles contain a high quality glycerin which helps keep the mouth and throat area moist, protected, and soothed. Agar-Agar (derived from dulse) lends the pastille their silky consistency while the natural extracts of fruit give Grether's Pastilles their great taste. The high quality of Grethers Black Currant Glycerin Pastilles are guaranteed thanks to a sophisticated and time consuming manufacturing process requiring considerable specialized knowledge, experience, and equipment. Before the pastilles are packaged, they must be allowed to ripen - a process that lasts 3 months. Grether's Pastilles are recommended for hoarseness, sore throats, croaky voice and dry mouth. People who have to use their voice a lot, e.g. through singing or extensive talking, benefit particularly from the calming, soothing and nourishing effect of Grether's Pastilles.
