From Ketchup to Mercury: Medicinal Myths and Lessons for Small Business Evolution

Throughout history, the pursuit of innovation has led humans down some surprising paths—sometimes with remarkable results, and other times with lessons learned the hard way. Two fascinating examples are ketchup and mercury, both of which were once hailed as medicinal marvels. Yep. That’s right. Ketchup and mercury were use as actual medicines.

While these substances might now seem worlds apart from the modern healthcare industry, they hold valuable lessons for small businesses striving to adapt, innovate, and abandon outdated practices.

Ketchup: A Tangy “Cure-All”

Today, ketchup is a staple condiment beloved for its role in enhancing burgers and fries, but in the 19th century, it was marketed as a medicine. In 1834, Dr. John Cook Bennett claimed that tomato ketchup could cure ailments like indigestion, diarrhea, and rheumatism. He touted tomatoes as “medicinal marvels,” and ketchup, in its concentrated form, was even sold as a pill.

This belief wasn’t entirely baseless. Tomatoes contain vitamins A and C, as well as antioxidants like lycopene, which we now know contribute to overall health. However, ketchup as a pharmaceutical solution lacked scientific backing and precise dosage. By the mid-19th century, it became clear that the condiment’s medicinal claims were overstated and unsupported. Eventually, ketchup returned to its culinary roots, where it remains firmly planted today.

Mercury: From Medicine to Misstep

Mercury’s history as a “cure-all” spans centuries. In ancient China and India, mercury was used in elixirs believed to grant longevity or vitality. During the Renaissance, it became a common treatment for syphilis, and its use persisted into the 19th century. Even Abraham Lincoln took it to cure his melancholy or depression. At the time, mercury’s toxicity was either unknown or ignored, and its immediate effects (like peeling skin) were often mistaken for signs that the treatment was working.

Eventually, the severe consequences of mercury poisoning—neurological damage, organ failure, and death—led to its rejection as a medicinal substance. Today, mercury is recognized as a dangerous toxin, not a cure. Its fall from favor highlights the dangers of relying on practices without rigorous testing and understanding.

Parallels for Small Businesses

The stories of ketchup and mercury serve as potent reminders for small businesses about the importance of self-assessment, adaptation, and embracing evidence-based improvements. Here’s how businesses can apply these historical lessons:

1. Scrutinize Longstanding Practices

Much like the initial faith in ketchup and mercury as medicinal agents, small businesses often cling to familiar practices without questioning their effectiveness. Whether it’s outdated marketing strategies, rigid work processes, or ineffective customer service approaches, relying on “the way things have always been done” can stifle growth and innovation.

So, regularly review your business practices and ask whether they still align with current trends and customer needs. Seek feedback from employees and customers to identify areas for improvement.

2. Embrace Evidence-Based Decisions

Ketchup and mercury gained traction based on anecdotal evidence and marketing rather than rigorous scientific scrutiny. Similarly, businesses can fall into the trap of following trends or hearsay without verifying their effectiveness. For example, investing heavily in a new tool or strategy because “everyone else is doing it” can backfire without proper research.

Don’t just follow the pack. Instead, use data and metrics to guide decision-making. Test new strategies on a small scale before committing significant resources, and analyze results to determine if they are worth scaling.

3. Stay Alert to Changing Contexts

Just as advancements in science and medicine eventually debunked the medicinal claims of ketchup and mercury, shifts in technology, customer behavior, and market conditions can render certain business practices obsolete. For instance, once-effective traditional advertising methods may no longer reach customers who now spend most of their time online.

This makes it clear that you should always stay informed about industry trends and be willing to pivot when necessary. Continuous learning and adaptability are key to staying relevant.

4. Balance Risk and Reward

Using mercury as medicine involved a significant risk—one that outweighed any perceived benefits. Businesses, too, must weigh risks against potential rewards when adopting new practices or abandoning old ones. While innovation is vital, reckless experimentation can harm a business’s reputation or finances.

The lesson here is to approach innovation with caution. Conduct risk assessments and involve stakeholders in decision-making to ensure changes are strategic rather than impulsive.

5. Communicate Change Effectively

When ketchup returned to its role as a condiment, it took time for public perception to shift. Similarly, businesses that implement change must clearly communicate why the change is happening and how it benefits stakeholders. Transparency helps build trust and eases transitions.

Whether introducing new products, updating policies, or shifting your brand’s focus, communicate openly with employees, customers, and partners. Share the reasoning behind the changes and provide support for those affected.

A Forward-Thinking Future

The evolution of ketchup and mercury from “cure-all” to cautionary tales reminds us that innovation is a double-edged sword. It can drive progress, but only when guided by evidence and a willingness to let go of outdated ideas. Small businesses can draw from these lessons to foster a culture of continuous improvement, ensuring they stay competitive in an ever-changing marketplace.

By scrutinizing practices, embracing evidence-based decisions, adapting to new contexts, balancing risks, and communicating change effectively, businesses can avoid the pitfalls of clinging to ineffective strategies. Just as ketchup found its rightful place in the culinary world and mercury was abandoned for safer treatments, businesses that are willing to evolve will find success in their own arenas.

How to Turn YOLO into Action

January 10, 2019 No Comments

YOLO — You Only Live Once. It’s true and that’s precisely the reason to give that business idea you have a real go. Really. What you’re waiting for isn’t likely to happen. You have to make it happen. So, let’s get right to it. Why Most Business Start-Up Roadblocks are Imaginary Okay, you need money, right? Wrong. But, you need an extensive business plan. Nope. You need a retail store, an office, a professional space. Probably not. Whatever the reasons, you’re probably talking yourself out of it rather than being thoughtful and careful. There are no limits on who can become a great entrepreneur. You don’t necessarily need a college degree, a bunch of money in the bank or even business experience to start something that could become the next major success. However, what you do need is a strong plan and the drive to see it through. —Entrepreneur.com While thoughtful and careful are good qualities, you need a healthy dose of impulse. In fact, almost every “roadblock” is merely you making an excuse. It’s no more complicated than you making it more complicated. 4 Simple Steps to Start a Business In reality, there are very few steps to start a business. With all the technology at your disposal and a little can-do attitude, it’s entirely possible. All you need is to do the following: Do a bit of research (but not too much). Learn about the product or service and its industry. You don’t need to become an academic expert. Research enough to get acquainted and feel more confident. Although, there’s a point of diminishing returns. If you keep going, you’ll eventually become overwhelmed. In other words, don’t get stuck in the paralysis of analysis or you’ll never actually get started. Test it out in a few different ways first. Whatever it is, test it out and don’t expect to charge — at least in the very beginning. Instead, ask for feedback and listen carefully. Others will give you invaluable input and that’s more valuable than money when starting out. (Now, if someone is willing to pay, give them a nice discount.) Start spreading the word, far and wide. Use social media, your family, your circle of friends, and acquaintances to spread the word. But, don’t hard sell. Just let people know about it. Make changes as you go and learn along the way. More than likely, you won’t hit the ball out of the park at first. You’ll need to make changes as you go. Be flexible and you’ll enjoy the ride a whole lot more.

How to Run a Work-from-Home Business

May 24, 2017 No Comments

The Internet, and more particularly, the world wide web, is revolutionizing so many things in our lives and the workplace is no different. More companies are using telecommuters to work for them, and, they are reaping the benefits of less overhead. In addition, the web makes starting a business quite simple. The biggest problem for a part-time or full-time entrepreneur is being able to effectively manage their time. Those work-from-home commercials and websites leave out many aspects of having a home-based business. While they tout the freedom and no need to endure frustrating daily commutes, they do leave some things out. The devil is in the details and it’s those things you might not think about that can cause you to fail. How to Run a Work-from-Home Business Running a work-from-home business not only takes a lot of entrepreneurial spirit, a vision, and an executable plan, it also requires a heavy amount of self discipline. When you stop to think about it, you’ll realize that having a home-based business means you won’t leave either work or home for the majority of the week. Another phenomenon (read: unrealistic expectation) that you’ll probably face from your spouse is about household chores. When you work outside the home, you don’t take any household appliances with you. The washer and dryer stay in the laundry room and the dishwasher remains right beside the kitchen sink. Ninety-seven percent of entrepreneurs love or like working from home, according to Money Tips.com’s recent survey of 160 successful Americans who run their businesses from home. Most enjoy it so much that 54 percent of them would turn down an offer of free office space just one mile from home. —Inc.com In addition to these, the lawn mower, vacuum, and all those household cleaning supplies won’t mysteriously jump into your vehicle. However, your significant other won’t necessarily grasp this concept, and, will wonder why there’s laundry to fold or dishes to take out of the dishwasher. Any one that runs a home-based business knows that chores are time consuming and just because the office is in the house, doesn’t mean all the chores will get done. In addition to this, you’ll be literally surrounded with distractions. It could be guitars, a game console, television, crafts, social media, or any other hobby or pastime that beckons day after day. If you want to run a successful work-from-home business, you’ll need to do the following daily: Create a schedule and stick to it. There’s a reason you have scheduled work hours when your job takes you out of the home and to a workplace. Do the same for your home-based business: create a schedule and don’t deviate from it. Let your clients or customers know your hours of operation and be available when needed. Get dressed for work. One of the perceived advantages people have about working out of the home is being able to dress down. While you can certainly work in your pajamas or just a tee-shirt and shorts, it does have a strong impact on your psyche, and, it’s not a good one because it promotes procrastination. Dress business casual and you’ll actually feel like it’s a work environment. Take breaks during the day. You do this at any workplace, but, when you start a home-based business, you’ll probably experience an urge to stay put in your office or work space to get things done. You need breaks during the day, so, put these into your schedule. It could be a short walk around the block, or even doing a chore, but these should be regular. Give yourself time off. Because your work and home environment are one-in-the-same, you’ll face the temptation to get this or that done when family is home. Don’t shortchange your family and you’ll find yourself to be a lot happier when there’s a good balance. Get out at least once per week. Don’t make the mistake of chaining yourself to your desk. You can go out to lunch and meet a friend or your spouse, but, be sure to do this at least once per week to keep your professional mannerisms sharp. Another tip you ought to take is to stay focused on your business. Because you might not regularly interact personally with others, your mind will tend to wander and you might get some new ideas to pursue. While it’s wonderful to be creative, you won’t be able to go off in different directions at once — keep your focus or you’ll increase your chances of failing. I just had this conversation yesterday with a Chief Marketing Officer who works virtually, and he enjoys the flexibility. We met at The Henry on Camelback in Phoenix. Personally, I prefer to get dressed, and head to my office with focus on my schedule and priorities. Call me traditional, but my work ethic has been embedded into my habits for over 35 years and it works for me. Now, I also find myself logging in when I get back to my home office. So, one of my incentives is to remain focused and productive at my office during the work week so that my evenings and weekends are free at home. It does take discipline, but this allows me time with my family and to enjoy a balanced life outside of my work. What I do like about working from home, is the flexibility it provides me and my family as well as the flexibility in the services that I can provide for my clients. What is most exciting is the business and career opportunities that our technology gives us. Go out and create your new opportunities … and start from home!
