The Surprising Truth: Why Ketchup Was Once Sold as Medicine

Have you ever squirted ketchup on your fries and thought, “This could cure my indigestion”? Probably not. But in the 1830s, ketchup was more than a tasty condiment—it was marketed as a medical marvel. Yes, that tangy red sauce we slather on burgers was once sold in pharmacies as a cure for everything from diarrhea to jaundice. Curious? Let’s dive into the bizarre history of ketchup as medicine and uncover why it was considered a 19th-century superfood.

The Origins of Ketchup: From Fish Sauce to Tomato Pills

Ketchup’s story begins far from the tomato fields of America. It traces back to ancient China, where a fermented fish sauce called “ke-tsiap” or “koe-cheup” was used in cooking. This salty, pungent sauce, made from fish innards and soybeans, was valued in traditional Chinese medicine for its supposed digestive benefits. By the 16th century, British sailors brought this concept to Europe, where cooks experimented with ingredients like mushrooms, walnuts, and oysters to recreate it. Tomatoes didn’t enter the scene until much later.

In 1812, Philadelphia horticulturist James Mease published the first known tomato-based ketchup recipe, but it wasn’t until the 1830s that ketchup took a medicinal turn. At the time, tomatoes were controversial in America—many believed they were poisonous due to their relation to the nightshade family. Enter Dr. John Cook Bennett, an Ohio physician who flipped this narrative on its head.

Dr. John Cook Bennett: The Ketchup Cure Pioneer

In 1834, Dr. John Cook Bennett began promoting tomatoes as a cure-all, claiming they could treat ailments like diarrhea, indigestion, jaundice, and even rheumatism. His enthusiasm wasn’t entirely baseless—tomatoes contain lycopene and pectin, which offer some health benefits, like antioxidants and digestive support. However, Bennett took it to another level by creating “tomato pills,” marketed as “Dr. Miles’ Compound Extract of Tomato” with drug manufacturer Archibald Miles. These pills were advertised as a universal remedy, with catchy jingles like “tomato pills will cure all your ills.”

Bennett’s claims sparked a ketchup craze. Pharmacies sold tomato-based extracts and pills, and newspapers buzzed with stories of relieved patients. But the science was shaky, and the market soon flooded with copycats. Some competitors even swapped tomatoes for laxatives, falsely claiming their pills could heal broken bones or cure scurvy. By the 1850s, these fraudulent products tanked ketchup’s medicinal reputation, and the trend fizzled out.

Why Did People Believe Ketchup Was Medicine?

So, why did 19th-century Americans buy into ketchup as a cure? It comes down to the era’s medical practices and cultural quirks:

• Tomato Skepticism and Hype: In the early 1800s, tomatoes were still viewed with suspicion. Some believed their “poisonous” nature made them potent medicine, as dangerous remedies were thought to be more effective. This aligned with the era’s “bleed, blister, and purge” medical philosophy, where extreme treatments like bloodletting were common.
• Fermentation Benefits: Ketchup’s roots in fermented fish sauce lent it credibility. Fermented foods were prized in traditional System: medicine for their digestive properties, and early ketchups retained this fermented quality.
• Marketing Genius: Dr. Bennett’s flair for promotion, combined with the novelty of tomatoes, created a perfect storm. His tomato pills were portable and easy to sell, appealing to a public desperate for health solutions in an era of limited medical knowledge.

For a brief period, from 1834 to the 1850s, ketchup was the hottest health trend in America. But its medicinal glory didn’t last long.

The Fall of Ketchup as Medicine

By the 1850s, the ketchup-as-medicine fad collapsed. Studies began debunking the exaggerated claims, showing that neither ketchup nor tomato pills delivered the promised cures. The rise of copycat products—many of which contained no tomatoes at all—further eroded trust. Some manufacturers used coal-tar dye or boric acid to preserve ketchup’s red color, raising health concerns. The public grew skeptical, and ketchup’s medicinal era ended.

But this wasn’t the end for ketchup. Enter Henry J. Heinz, who revolutionized the condiment in 1876. Heinz’s recipe—made with ripe tomatoes, distilled vinegar, brown sugar, salt, and spices—focused on flavor and shelf life, not health claims. His ketchup became a household staple, cementing its place on dinner tables worldwide. Today, Heinz dominates with a 60% market share in the U.S. and 82% in the U.K., selling over 650 million bottles annually.

Ketchup Today: A Condiment, Not a Cure

Modern ketchup isn’t prescribed for upset stomachs, but it does offer some nutritional perks. According to the U.S. Department of Agriculture, ketchup contains small amounts of antioxidants and vitamins from tomatoes, though its high sugar (22g per 100g) and salt content mean it’s best enjoyed in moderation. Americans consume about 71 pounds of ketchup per person annually—that’s three bottles per person!

Ketchup’s journey from a fishy Chinese sauce to a medicinal fad to a global condiment is a wild ride. It’s a reminder that even everyday items can have surprising histories. Next time you dip your fries, you might chuckle knowing that ketchup was once sold alongside cough syrups and tonics.

Fun Facts About Ketchup’s Quirky Past

• World’s Largest Ketchup Bottle: In Collinsville, Illinois, a 70-foot-tall ketchup bottle (originally a water tower) holds 100,000 gallons, equivalent to 640,000 bottles of ketchup. Built in 1949, it’s now a quirky landmark.
• Ketchup Phobia: Some people suffer from mortuusequusphobia, an extreme fear of ketchup, reacting strongly to its sight or smell.
• Guinness World Record: In 1998, Hikaru Nakasone set a record by squirting ketchup 30 feet and 9 inches from a bottle. Talk about a condiment cannon!

How Ketchup Shaped Culinary History

Ketchup’s medicinal phase may have been short-lived, but it paved the way for its culinary dominance. The tomato craze sparked by Dr. Bennett helped Americans embrace tomatoes as food, not poison. By the late 19th century, home cooks were experimenting with ketchup recipes, and Heinz’s innovation made it a kitchen essential. Today, ketchup’s sweet-sour-umami flavor profile hits all five taste buds, making it a versatile companion to fries, burgers, and even scrambled eggs.
