Ahlgrens was a Swedish confectionery company. It was started by Fredrik Ahlgren in the town of Gävle in 1885 as a store that sold paint and wallpaper. The business later started to also make and sell various types of chemicals, perfumes and other products. In 1908, the business introduced a brand of mouthwash called Läkerol. The next year, pastille started to be sold under the same brand, and is still sold in multiple countries in several variants.
