Before the 1900s, mislabeling of foods and drugs was common, and often intentional. States had primary control over domestically produced products. Many foods and drugs carried unsubstantiated health claims such as cures for cancer or baldness.
Labels did not necessarily reflect what was in the product. In the following pictures, the tomato paste is only 14% tomatoes, and the maple syrup is only 1.5% maple syrup.
