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modern healthcare industry, they hold valuable lessons for small businesses striving to adapt, innovate, and abandon outdated practices.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 Move Past a Bad Business Policy

May 16, 2017 No Comments

You identified a problem, took action, and enacted a new policy. Your people don’t like it (read: hate it), and, now you’re dealing with the fallout. It’s not an enviable position to be in, but nonetheless, here you are and now, you have to take action–again. The advice you’ve long heard about learning from your mistakes is now a reality, and, you are willing and able to accept it. The problem is how to move past a bad business policy and avoid repeating the same mistake in the future. Though you know this one backfired, you can’t be sure of how other policies you enact moving forward will impact your team and your business at-large. It’s okay to be retrospective and to attempt to peer around the corner, but for now, what you really need is to make things right. How to Move Past a Bad Business Policy The very fact that you are willing to recognize you made a mistake is a positive sign. However, you might still have a problem to deal with and you don’t want Murphy walking back into your organization, wielding his rule which states, “every solution breeds new problems.” You’ve already seen that unfold and it should have phased you enough to make a change. …we hate to fail. We fear it, we dread it, and when it does happen, we hold onto it. We give it power over our emotions, and sometimes we allow it to dictate our way forward (or backward). Some of us go to great lengths to avoid failure because of all the pain and shame associated with it. —Forbes It’s also good that you’re self-aware enough to accept the blame instead of digging in and defending what you’ve done, which will only insult your team members. So, how do you prevent this from happening again, but, still be able to enact policies that don’t end-up backfiring? Here are some helpful bits of advice you can use: Don’t be afraid to admit you made a mistake. This bears repeating, and, it does so big time. There’s little else more damaging than a leader who won’t admit he or she is wrong. It’s arrogant, harmful, and can cause good people to leave. In fact, the best thing to do is to have a sit down with your employees and others and talk about how you arrived at the decision, why it was wrong, and, how you plan to resolve the situation. Identify the problem and be proactive. Speaking of resolving the situation, you’re inevitably going to face problems again, so, before they have a chance to materialize, do what you can to thwart them. This won’t necessarily be easy, but your intuition will tell you when something is about to become a problem. Get ideas from your team about solutions. Your team members are among your most valuable assets. Don’t go it alone, speak openly with them and listen to their suggestions. You’ll likely find that doing so will present many ideas which can be molded together for a solution. Avoid new policies that create new problems. This is more difficult than you might think, but it’s still possible. Before you do enact a new policy, think about what it will do and how it will be received by your team. If you play it out and identify possible result scenarios, you can usually avoid making another bad policy. In my 34 years of business experience with ownership in 9 different businesses and consulting/coaching with hundreds of business owners, I have a long list of bad business policies that I have made. All of the policies well intended, but many times not fully thought through. My greatest lesson in making policies, is that hiring the right people with the right core values will minimize the policies that seem necessary to police and hold your team accountable. Those employees with the right core values will do what is right almost all of the time, thereby eliminating the need for many policies. [shareaholic app=”follow_buttons” id=”26833294″]

I Just Learned One of My Best Employees Criticized My Business On Social Media, What Should I Do?

March 1, 2021 No Comments

You’ve just discovered one of your best team members has criticized your company on social media. So, you’re wondering what to do about it. Well, that depends if the comments were overall positive or negative. If the former, there’s quite a bit you can do. However, if it’s the latter, there’s relatively little you can do. Read on to learn more about how to deal with employees who criticize their organizations on social media. Dealing with Negative Employee Comments about Your Business Let’s begin with a negative situation. You’ve recently found out a great employee (who you like and trust) has made some really disparaging comments about your company — maybe even directed at you personally — on social media. Now, you’re wondering what to do about it. If the comments are negative and harmful to your business’ reputation, you most definitely need to address the situation immediately. Criticism in the workplace can be constructive if an individual is pointing out concrete inefficiencies and offering suggestions for positive improvements; or criticism can be destructive, when one person tears down and negatively critiques the actions of others while offering no suggestions for positive improvement. —Houston Chronicle Small Business This is a difficult conversation to have, there’s no doubt about it. But, a stern warning might be enough to move past the moment. It’s probably also necessary to talk about his or her future and potential separation from the company, should the behavior continue. While it’s a hard thing to do, derogatory comments simply are not acceptable. So, invite him or her to vent their grievances in private instead of on social media. Dealing with Positive Employee Comments about a Your Business If this is a situation where the comments were critical yet constructive or positive, it’s an entirely different set of circumstances. Since it’s a totally opposite attitude, you might still be personally hurt or feel undermined, but it’s far better than dealing with a completely negative scenario. Here are some effective methods for dealing with a good employee who publicly criticized your business on social media: Make him or her understand the proper context. The very first thing you need to do is to let him or her know that it is not acceptable or appropriate to criticize the company on social media. Instead, the appropriate time and place is right in the workplace, where discussions are private and between colleagues, where such input belongs. Let your employee know your door is always open. Of course, it’s up to you to open your office door and make all your employees understand they have an open-ended invitation to speak with you at any time they feel it is necessary. (Obviously, you’ll need to set some boundaries to ensure there’s mutual respect and interactions remain overall positive.) Solicit feedback from all your team members regularly. While this might be super-obvious, it’s most definitely worth repeating. You cannot operate in your business in a vacuum. It’s not a good dynamic and worse yet, when you don’t listen to the people around you who are in the trenches with you, it’s only going to erode the environment and worsen over time. What other suggestions do you have? How else would you handle such a situation? Please take a moment to share your thoughts and experiences so others can benefit from your unique perspective!

The truth is, the former is obvious, while the latter silently damages a company from within. That’s right. Although most entrepreneurs think a low turnover rate is great, it can actually be doing extensive harm. Read on to learn why.
