When you think of ketchup, chances are you picture a squirt on fries, burgers, or hot dogs. But here’s a fact that flips the bottle upside down: in the 1800s, ketchup wasn’t a condiment at all — it was sold as medicine.
Yes, the same red sauce in your fridge was once marketed as a cure for everything from indigestion to diarrhea. The story of how ketchup transformed from a so-called health tonic to the world’s favorite condiment is a fascinating look at marketing, food history, and human belief.
From Fermented Sauce to Tomato Experiment
Ketchup’s roots stretch back centuries before tomatoes. The original word “kecap” (pronounced kay-chap) came from Southeast Asia and described a fermented fish sauce. When British traders encountered it in the 1600s, they adapted the idea, creating sauces from mushrooms, walnuts, oysters, and more.
By the early 1800s in America, tomatoes — once viewed with suspicion as potentially poisonous — were gaining popularity. Enterprising cooks began making tomato-based ketchup. Unlike today’s sweet and tangy version, early tomato ketchups were savory, spicy, and closer to a cooking sauce than a burger topping.
Ketchup as Cure-All
Here’s where it gets wild. Around the 1830s, an Ohio physician named Dr. John Cook Bennett claimed that tomatoes — and by extension tomato ketchup — could cure digestive issues, jaundice, and even rheumatism. His lectures gained attention, and soon entrepreneurs ran with the idea.
“Tomato pills” made from concentrated ketchup extracts were sold across the U.S. as patent medicines. Traveling salesmen pushed bottles and pills with bold claims in newspapers and town fairs. Ketchup wasn’t just food — it was a miracle in a jar.
The Shift to Condiment
But the boom didn’t last. By the mid-19th century, medical research began debunking the supposed cures. At the same time, many bottled ketchups spoiled quickly, leading to distrust. Consumers wanted safe, reliable food products — not dubious tonics.
Enter Henry Heinz in the late 1800s. Heinz revolutionized ketchup production with stricter standards, glass bottles (to prove purity), and consistent recipes. His marketing dropped the “medicine” angle entirely and leaned into trust, cleanliness, and flavor. By the early 1900s, ketchup had fully transitioned into the condiment we know today.
Lessons From Ketchup’s History
The story of ketchup shows how marketing can transform public perception. What started as a folk remedy became one of the most ubiquitous foods on the planet, thanks to clever branding and a cultural shift toward safe, standardized products.
So the next time you reach for ketchup, remember: you’re holding the bottle of a product that once promised to heal your stomach, not just spice up your fries.
Extra Nuggets for Curious Readers
- By the 1840s, advertisements for tomato ketchup pills claimed they could cure nearly every ailment. Many of these were classic examples of “patent medicines,” a booming but largely unregulated industry.
- Heinz’s decision to use clear glass bottles in the 1870s was revolutionary. At a time when many manufacturers hid spoiled or contaminated food in dark bottles, Heinz used transparency as a trust signal — a branding move still admired in marketing case studies today.
