What is oregano?
Oregano is an herb or plant commonly used in cooking. The plant contains compounds like carvacrol and thymol, which have shown to have antimicrobial (germ-fighting) and antioxidant (cell-protecting) properties in lab studies.
Because of this, oregano is often marketed as a natural remedy for infections or something that can make the immune system stronger. But just like the flavor of oregano, these claims are bold – and not sufficiently backed by science.
Does oregano make kids’ immune systems stronger?
There’s no strong evidence that oregano strengthens your child’s immune system. Most of the research on oregano or oregano oil has been conducted in test tubes or with animals, not in children or adults.
Our immune system is complex. It can be underactive (which makes it harder to fight infections), well balanced, or overactive (which can contribute to conditions like autoimmune diseases). Because of this delicate balance, it’s important to have well‑designed clinical trials conducted with human subjects before we can say definitively that an herbal supplement like oregano truly supports the immune system. Such studies simply don’t exist yet.
Why do people think oregano helps immunity?
The reasons oregano has gained a reputation as something that can help the immune system include:
- Oregano has long been used in traditional and herbal medicines because of its perceived benefits
- Studies in controlled laboratory environments have shown that compounds or molecules in oregano can stop the growth of pathogens like bacteria and viruses
- A few such studies have been done in farm animals and show oregano may help stop the spread of disease, but such studies have not been done in people
Something that shows antimicrobial properties in a lab or in animal studies does not automatically mean it will improve immune systems in people. Before recommendations could be reliably made for use in people, we would need more research studies conducted with human subjects to study the effects of oregano.
Is oregano safe for kids?
Oregano oil is much more concentrated than the herb used in cooking. It can irritate skin or parts of the digestive tract such as the mouth and stomach if used incorrectly. Because no studies exist on using oregano in children, healthcare professionals don’t know what a safe dose is, and whether this safe dose is even effective. With potential side effects and no clear benefits, oregano is currently not recommended as a way to strengthen the immune system in children. Of course, oregano can still be enjoyed for its flavor – like sprinkled on pizza – as part of a well-balanced diet.
What actually supports a child’s immune system?
Focus on the basics that have been proven to help keep kids healthy:
- Routine childhood vaccines
- Adequate sleep
- Balanced nutrition
- Regular physical activity
- Handwashing and infection prevention
- Routine pediatric care
These strategies currently have far more evidence than herbal supplements do for preventing illness and helping your child thrive.
What are we still learning?
Oregano is a tasty plant and safe to use in cooking, but we don’t have enough evidence to conclude that oregano strengthens the immune system in children. While studies in the lab and with animals show promise, more studies are needed to understand how oregano affects the immune system in people, especially in kids who may have more side effects from taking supplements.
If you’re considering supplements for your child, talk with your pediatrician first. Most of the time, the best way to support your child’s immune system is through healthy habits — not herbal remedies.
