10 Extremely Dangerous Historical Home Remedies and 10 That Are Still Used Today

In the past, mercury was used in ointments and treatments designed to cure all kinds of ailments, including skin problems and even infections. In reality, mercury is toxic and can damage the brain, kidneys, and nervous system. In other words, it’s an old-fashioned remedy that you certainly wouldn’t want to find in your medicine cabinet.

For a very long time, it was believed that bloodletting could cure all sorts of ailments, from fever to headaches. This belief was based on ancient medical theories about the balance of bodily humors, which seemed convincing for centuries and caused many problems, since losing blood when you’re already sick is generally not the best way to get back on your feet.

Arsenic somehow found its way into the tonics and beauty products of the past, which makes us truly appreciate modern labeling laws. Small amounts were sometimes sold as beneficial for vitality, complexion, or overall health. The problem, of course, is that arsenic is a poison that can cause vomiting, diarrhea, cancer, and organ failure. 

Lead was used in powders, creams, and home remedies because it produced certain desired effects, particularly on the skin. Unfortunately, the body does not respond well to being regularly covered in lead or exposed to it. Over the long term, lead poisoning can affect the brain, the nervous system, the kidneys, and many other organs. 

Belladonna comes from a plant, which has contributed to its misleading reputation as a “natural” product. Historically, it was used in various remedies and even in cosmetic practices, even though it contains compounds that can be extremely toxic. If taken in the wrong dose, it can cause serious symptoms, including confusion, a rapid heartbeat, and even worse. 

At one time, tobacco smoke was used to treat certain conditions, particularly respiratory disorders. This idea seems particularly outdated today, but it was once believed that smoke could have beneficial effects on the body. As one might expect, smoking tobacco is not a sensible solution to respiratory problems and is more likely to make the situation worse. 

Some traditional cough remedies contained opioids, and yes, that’s just as concerning as it sounds. They could soothe a cough and relieve pain, which made them seem effective in the short term. They also carried serious risks, including addiction, overdose, and dangerous side effects. 

Soda lye was once commonly used in certain home remedies because it was easy to obtain and seemed powerful enough to solve problems. The problem is that it is caustic and can seriously damage the skin and tissues. It is still used today in some soaps and personal care products, but we now have a much better understanding of its dangers, and modern chemistry makes it much easier to control.

Turpentine has been widely used as a remedy for thousands of years, either ingested or applied to treat a wide variety of ailments, as traditional medicine tended to associate its strong odor and tingling sensation with genuine effectiveness. In reality, turpentine can be toxic and irritating; it can cause kidney and lung damage, gastrointestinal problems, and, in severe cases, lead to coma or death.

Once radioactivity was discovered, certain products were marketed as miracle cures, as science sparked enthusiasm and people got carried away by their excitement. Radium water and other similar tonics were sold as energy drinks or fortifying beverages, which was deeply regrettable. Since exposure to radiation can lead to serious illnesses and long-term health effects, this was not a wellness trend worth pursuing. 

Now that we’ve discussed remedies from the past that seem absurdly dangerous today, let’s talk about those that have truly stood the test of time.

Honey has long been used to treat minor wounds, and unlike many traditional remedies, its use is based on solid scientific evidence. It helps create a protective environment and has antibacterial properties that made it useful long before the advent of modern pharmacies. Today, medical-grade honey is still used in certain wound care settings.

Ginger has long been used as a home remedy for an upset stomach, and many people still rely on it today. A ginger tea, ginger candies, or ginger soda made with real ginger can provide relief when your stomach is acting up. It’s one of those remedies that has stood the test of time because it’s simple and often truly effective.

Peppermint has been used for generations to relieve digestive problems, and it remains a well-known remedy to this day. Because it relaxes the stomach muscles, a cup of peppermint tea can provide a soothing sensation when your stomach is upset or feeling full. It’s not a miracle cure for all digestive problems, but its popularity is no accident. 

Oats have been used for a very long time to soothe irritated skin, and this remedy has never needed flashy branding to remain relevant. Colloidal oatmeal is still used in modern products designed to soothe dryness, itching, and mild irritation. It’s gentle, convenient, and doesn’t cause a burning sensation on the skin—which already gives it a leg up over many traditional remedies. 

Rinsing with warm salt water is a home remedy that has been used for centuries to relieve mouth irritation or a sore throat. Even today, it’s still one of the simplest things you can do when you have a sore throat or sensitive gums. It won’t cure every ailment, but it can help you feel a little better without much effort. 

Long before the advent of humidifiers and other sophisticated devices, people were already leaning over a pot of boiling water to relieve their stuffy noses and chest congestion. The principle still holds true, as moisture helps thin mucus and makes breathing easier. However, it’s important to exercise caution and avoid burns—this is a crucial detail. When used carefully, steam remains one of those time-honored remedies that people continue to swear by.

It’s no coincidence that chicken soup is the quintessential “get-well” meal. A hot broth that’s easy to swallow and lightly nourishing can be a real comfort when you’re feeling under the weather. It’s not so much a miracle cure as it is a source of comfort, hydration, and nutrition when you can barely keep anything down. 

Cloves have been used for centuries to relieve toothaches, and some people still use them today to get temporary relief. Their active compounds can produce an anesthetic effect, which explains why they have remained in use. They are not a substitute for a visit to the dentist when there is a real problem, but their use is based on practical considerations. 

Aloe has been used for generations to soothe the skin, and it’s still a go-to remedy after excessive sun exposure or a minor kitchen accident. It stimulates collagen production and skin regeneration, while its anti-inflammatory and moisturizing properties help speed up healing. It’s also soothing, refreshing, easy to use, and doesn’t claim to be anything more than it is. 

Chamomile has long been used to promote relaxation. A cup of hot chamomile tea remains one of the most common ways to unwind at the end of a long day. As a mild sedative, studies have shown that it can improve sleep in people suffering from insomnia.
