Your Favorite Condiment Was Once a Cure-All: Ketchup as Medicine!

In the early 19th century, the landscape of medicine was vastly different from today, often blurring the lines between food and remedies. During this period, many common household items were believed to possess curative properties, and regulation of medicinal claims was minimal to non-existent. Interestingly, before it became a beloved condiment, the tomato itself was viewed with suspicion by many Americans, with some even considering it poisonous due to its resemblance to nightshade berries.

It was into this environment that Dr. John Cook Bennett, an Ohio physician, stepped forward in the 1830s, championing the tomato as a miracle cure-all. He vigorously promoted tomato-based ketchup, claiming it could treat a host of ailments including indigestion, diarrhea, jaundice, and even rheumatism. His enthusiasm led him to publish recipes and, more notably, to partner with a manufacturer to sell his formula in a concentrated "tomato pill" form, which quickly gained popularity. This sparked a booming industry, with various manufacturers producing their own versions of tomato pills and extracts.

However, like many "patent medicines" of the era, the medicinal claims surrounding ketchup were eventually dismissed as quackery. The widespread fraud, exaggerated promises, and the lack of scientific backing meant these products did not live up to their miraculous assertions. By the 1850s, the tomato pill craze faded, and ketchup transitioned from a supposed remedy back to the flavorful culinary staple we recognize today. While modern science confirms tomatoes are rich in beneficial antioxidants like lycopene, the early medicinal applications were based on speculation rather than evidence.
