Some people may like the idea of using "natural" health remedies. They may think it sounds safer than chemicals or drugs. But here's the truth: Natural doesn't always mean safe. And it doesn't always mean effective either.

In fact, believing that natural health remedies is better may sometimes lead to more harm than good.

Here's what Mayo Clinic experts say about what natural really means — and what's actually good for you.

What a label doesn't tell you

The word "natural" shows up on many products — supplements, skin creams, teas and even toothpaste. But there's no clear, legal definition of the word when it comes to health products.

Some so-called natural remedies are highly processed. Others may come from plants or herbs but still have strong effects on the body. For example, the herb St. John's wort can interfere with many medicines or trigger manic episodes in people with bipolar disorder.

And just because something comes from nature doesn't mean it can't hurt you. A plant called foxglove contains a chemical used to make heart medicine — but eating the plant itself can be deadly.

Even vitamins and natural supplements can be harmful if taken at the wrong dose or mixed with certain medicines.

The problem of safety testing

Unlike prescription drugs, many natural health remedies don't go through strict safety testing. In the U.S., the Food and Drug Administration, also called FDA, does not check most supplements before they go on the market. That means they:

• May not contain what the label says.
• May be contaminated or mixed with other substances.
• May not have been tested for safety or effectiveness.

Always talk to your healthcare team before starting any new supplement, even if it's "just a vitamin."

What are safe, natural ways to stay healthy?

There are healthy, natural ways to support your body and mind, and many of them are backed by years of research. Here are some safe, evidence-based options to try:

• Social connection. Spending time with people you care about or volunteering with others can boost your mood, lower stress and help you live longer.
• Time in nature. Spending at least two hours a week in nature can boost your health and well-being. Even taking a simple walk or sitting under trees can make a real difference in how you feel.
• Healthy eating. A balanced diet with fruits, vegetables, whole grains and lean proteins gives your body the nutrients it needs to heal and stay strong. Reducing added sugar and processed foods also can improve energy, sleep and mood.
• Regular movement. Exercise is one of the most powerful natural tools available. It can help reduce anxiety and depression, improve heart health, support weight loss and help prevent stroke. Even a daily walk makes a difference.
• Mindfulness. Practices like meditation and yoga are simple, free and safe to try. Plus, these activities may help lower blood pressure, improve sleep and reduce pain.
• Sleep. Getting enough rest is one of the best things you can do for your health. Aim for 7 to 9 hours a night. And try to keep a regular bedtime, even on weekends.

Ask questions, stay safe

There's nothing wrong with being curious about natural health remedies. But it's important to remember:

• Natural doesn't always mean safe.
• Supplements can have side effects or interact with medicines.
• The safest, most effective natural treatments often involve lifestyle changes, not pills or powders.

If you're considering a natural product or wondering what's safe for you, talk to your healthcare team. Your care team can help you make smart choices that support your health, both naturally and safely.
