Altoids are a brand of mints, sold primarily in distinctive metal tins. The brand was created by the London-based Smith & Company in the 1780s, and became part of the Callard & Bowser company in the 19th century. Their advertising slogan is "The Original Celebrated Curiously Strong Mints", referring to the high concentration of peppermint oil used in the original flavour lozenge. The mints were originally conceived as a lozenge intended to relieve intestinal discomfort.
