Sisu cough drops made in the Seres factory in Turku became available in stores in 1928. Their recipe was developed by chemist Johan Ponkamo who wanted to create a Finnish product to compete with imported Swedish candies. Ponkamo spent a long time looking for the perfect way to combine licorice and gum arabic. The exact consistency of the unique aroma is still a closely guarded business secret. Sisu as a concept is difficult to translate: it can mean perseverance, guts, grit, spunk and stamina. The cough drops were recommended for speakers, singers and smokers.
