Today, ketchup is a familiar companion to fries, burgers, and hotdogs. But in the 1830s, it wasn’t just a condiment—it was marketed as a cure.

It all began with Dr. John Cook Bennett, a physician and medical writer who believed that tomatoes held extraordinary healing properties. At the time, tomatoes were still relatively new to American diets and often regarded with suspicion. Bennett, however, saw potential. He claimed that tomatoes could treat a wide range of ailments, including indigestion, jaundice, diarrhea, and even rheumatism.

Dr. Bennett didn’t just publish articles praising tomatoes—he took it a step further by creating recipes for “tomato pills” and tomato-based medicines. His enthusiasm sparked public interest, and soon enough, entrepreneurs seized the opportunity. One such individual was Archibald Miles, who began mass-producing and selling tomato pills, riding the wave of popularity initiated by Bennett’s claims.

This trend gave ketchup an unexpected new life. Though tomato pills were the primary product, ketchup—already beginning to appear as a food product—was marketed as a medicinal solution too. Early ketchup was quite different from the sweet, thick version we know today. It was spicier, often thinner, and sometimes made with ingredients like mushrooms or anchovies. But with the tomato craze in full swing, tomato ketchup found its footing in the medicinal market.

However, this phase didn’t last long. By the late 1840s, the public began to question the extravagant claims of miracle cures. Medical professionals increasingly scrutinized such remedies, and as regulations around medicine improved, ketchup lost its medical reputation. It transitioned fully into the realm of food, where it remains a staple.

Looking back, it’s a quirky footnote in the history of food and medicine. Ketchup as a cure-all may sound strange today, but it’s a reminder of how perceptions shift over time. What was once seen as a health tonic is now the star of the condiment aisle. The story of medicinal ketchup is a fascinating blend of early marketing, dietary evolution, and the ever-changing landscape of public trust in health claims.

So, the next time you squeeze ketchup onto your fries, take a moment to imagine it being handed out by a 19th-century doctor, promising to heal what ails you.
