There’s a good chance you have a few bay leaves tucked away in your kitchen cabinet.
Most people use them to flavor soups, stews, and slow-cooked meals. Once the food is ready, the leaves are removed and forgotten.
But recently, another household habit has been attracting attention: boiling bay leaves in water.
Some people do it because they love the aroma. Others enjoy bay leaf tea, while some believe the steam can freshen a room or offer surprising wellness benefits.
So what’s really happening when you place a few bay leaves in a pot of simmering water?
Boiling bay leaves releases aromatic compounds that can make your kitchen smell pleasant, and the leaves can also be used to prepare a simple herbal infusion. But many of the dramatic health claims circulating online aren’t supported by reliable scientific evidence.
Let’s explore the traditional uses, the practical benefits, and a few precautions worth knowing.

1. The Real Reason Bay Leaves Smell So Good When Boiled
Bay leaves come from Laurus nobilis, an aromatic evergreen tree native to the Mediterranean region.
The leaves contain volatile aromatic compounds, including 1,8-cineole, linalool, and other naturally occurring substances.
When bay leaves are heated in water, some of these compounds are released into the air along with water vapor.
This creates the distinctive herbal scent many people associate with homemade soups and Mediterranean cooking.
The aroma may feel comforting or refreshing, especially if you enjoy herbal fragrances.
However, a pleasant smell isn’t the same as disinfecting the air or removing airborne pathogens.
Boiling bay leaves hasn’t been shown to sterilize rooms, eliminate household toxins, or replace proper ventilation and cleaning.
2. A Simple Way to Make Your Kitchen Smell Wonderful
One of the most practical uses of bay leaves is as a natural simmer-pot fragrance.
You don’t need complicated ingredients or expensive products.
Ingredients
- 3–4 dried culinary bay leaves
- 3 cups water
- 2 lemon slices, optional
- 1 small cinnamon stick, optional
Preparation
- Add the water to a small saucepan.
- Place the bay leaves in the water.
- Add the optional lemon and cinnamon.
- Bring to a gentle simmer.
- Reduce the heat and allow the aroma to develop for 10–15 minutes.
- Turn off the stove and allow the pot to cool safely.
Never leave a simmering pot unattended, and don’t let it boil dry.
Keep hot water and steam away from children and pets.
This method may temporarily make a room smell pleasant, but it isn’t an air purifier or a substitute for addressing the source of unpleasant odors.
3. What About Drinking Bay Leaf Tea?
Bay leaves have a history of traditional culinary and herbal use.
Some people prepare a light infusion by steeping a small number of culinary bay leaves in hot water.
Researchers have investigated compounds found in bay leaves for antioxidant and other biological properties.
However, most of the evidence comes from laboratory research or small studies.
There’s insufficient clinical evidence that bay leaf tea reliably treats diabetes, high blood pressure, arthritis, or digestive disorders.
If you enjoy herbal drinks, a mild bay leaf infusion can be an occasional beverage for many healthy adults.
But it shouldn’t replace prescribed medication or appropriate medical care.

5. Can Bay Leaves Help With Blood Sugar?
This is one of the most frequently repeated claims about bay leaf tea.
A few small studies have investigated bay leaf preparations and markers related to glucose metabolism.
Some reported changes in certain measurements, but the research is too limited to establish an effective treatment.
The preparations studied aren’t necessarily equivalent to homemade bay leaf tea.
There is no reliable evidence that drinking bay leaf water normalizes blood sugar or cures diabetes.
People taking insulin or other glucose-lowering medication should be particularly cautious about using herbal products for medicinal purposes.
6. Can the Aroma Help You Relax?
Smell is closely connected with memory and emotion.
A familiar aroma can make a space feel comforting.
For some people, the scent of bay leaves may evoke home cooking, family meals, or peaceful evenings.
This experience is personal and doesn’t require a medical explanation.
There’s no strong clinical evidence that boiling bay leaves treats anxiety or insomnia.
But enjoying a pleasant kitchen aroma while preparing dinner may still be a satisfying ritual.
7. Four More Ways to Use Bay Leaves Around the Home
Flavor homemade soups.
Add one or two whole bay leaves to a pot of vegetable soup. Let them simmer with the vegetables, then remove them before serving.
Experiment with pantry aromas.
Some people place dried bay leaves in pantry cupboards because they dislike certain insect odors. However, bay leaves aren’t a proven method of preventing pantry infestations. Airtight containers and proper cleaning are more reliable.
Add depth to tomato sauces.
Simmer one bay leaf with tomatoes, garlic, and olive oil for a subtle herbal flavor. Remove the leaf before serving.
Make a fragrant decorative bundle.
Combine dried bay leaves with cinnamon sticks and dried orange slices for a simple kitchen decoration. Keep it away from flames and curious pets.
8. Can Bay Leaves Clean the Air or Remove Bad Energy?
There are plenty of claims online about boiling or burning bay leaves to cleanse a home.
Some are based on cultural traditions, while others are presented as scientific facts.
Boiling bay leaves can release a pleasant scent, but it doesn’t remove pollutants or eliminate harmful microorganisms from indoor air.
Burning bay leaves is a different matter. Smoke contains fine particles that can irritate the respiratory system, particularly in people with asthma or other lung conditions.
If your goal is fresher indoor air, ventilation, addressing moisture problems, and using appropriate filtration are more effective approaches.
9. Important Safety Precautions
Bay leaves are generally safe when used in normal cooking amounts, but a few precautions matter.
- Use only culinary bay leaves from a trusted supplier. Some plants called laurel, including cherry laurel, are poisonous and should never be substituted.
- Remove whole leaves before serving food or tea because their tough texture can pose a choking or digestive injury hazard.
Healthline+1
- Never ingest concentrated bay leaf essential oil.
- Avoid using strong medicinal preparations without professional advice, especially if you’re pregnant, breastfeeding, taking diabetes medication, or managing a chronic illness.
- Never leave boiling water unattended, and avoid deliberately inhaling hot steam, which can cause burns.
10. Why This Simple Habit Has Become So Popular
Part of the appeal is how inexpensive and accessible it is.
You don’t need special equipment, complicated ingredients, or an expensive product.
A few bay leaves and a pot of water can produce a distinctive aroma that many people enjoy.
It also connects with a broader interest in traditional household practices and making use of familiar kitchen ingredients.
But it’s worth separating what feels pleasant from what has been scientifically demonstrated.
Aromatic herbs can make everyday routines more enjoyable without needing to be presented as miracle remedies.
The Bottom Line
Bay leaves have earned their place in kitchens around the world because of their unmistakable fragrance and ability to enhance savory dishes.
Boiling them in water releases that aroma, which explains why some people enjoy using them in simmer pots or mild herbal infusions.
The surprising benefit isn’t that bay leaves magically purify your home or cure disease. It’s that such an ordinary spice can add warmth, fragrance, and flavor to everyday life.
And sometimes, that’s reason enough to take another look at what’s already sitting in your spice cabinet.
