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.

A mint or breath mint is a food item often consumed as an after-meal refreshment or before business and social engagements to improve breath odor. Mints are commonly believed to soothe the stomach given their association with natural byproducts of the plant genus Mentha. Mints sometimes contain derivatives from plants such as peppermint oil or spearmint oil, or wintergreen from the plant genus Gaultheria. However, many of the most popular mints citing these natural sources contain none in their ingredient list or contain only trace amounts.
