Bay Leaf Tea Benefits, Side Effects & How to Make It

Bay leaf tea has been a go-to remedy in kitchens around the world for centuries, and for good reason.

This earthy, aromatic brew made from the dried leaves of the Laurus nobilis tree offers surprising health benefits, from calming an upset stomach to helping manage blood sugar levels.

But like any herbal tea, bay leaf tea works best when you know what you’re getting into. Some people can drink it daily without a second thought.

Others, especially folks on certain medications, need to be more cautious.

In this guide, you’ll find the researched benefits, a simple recipe, and the side effects worth knowing about so you can decide whether bay leaf tea earns a spot in your routine.

Key Benefits at a Glance
Bay leaf tea may support digestive health, help regulate blood sugar, reduce inflammation, and provide respiratory relief. It contains vitamins A, B6, and C, along with potassium, iron, and antioxidants. Research suggests the bioactive compounds in bay leaves (eugenol, linalool, cineole) contribute to its anti-inflammatory, antimicrobial, and calming properties. For most people, 1-2 cups daily using 1-2 dried leaves per cup is a reasonable amount. Always strain thoroughly before drinking, and check with your doctor if you take medications for diabetes, blood pressure, or blood thinning.

What Does the Research Say About Bay Leaf Tea?

A 2009 study published in the Journal of Clinical Biochemistry and Nutrition found that consuming 1-3 grams of bay leaves daily for 30 days improved insulin function and reduced fasting blood sugar by 21-26% in participants with type 2 diabetes.

That same study also noted improvements in cholesterol and triglyceride levels.

A 2020 study in the Journal of the American College of Nutrition evaluated daily bay leaf tea consumption in healthy volunteers and found positive effects on lipid profile biomarkers.

That said, most clinical research has used concentrated bay leaf extracts rather than homemade tea, where potency varies depending on leaf freshness, steep time, and preparation method. WebMD notes that bay leaf consumed in food amounts is generally safe, while medicinal use of ground bay leaf is rated “possibly safe” in the short term. No standardized therapeutic dose currently exists.

The takeaway? Bay leaf tea shows genuine promise, but it’s not a miracle cure. Treat it as a supportive addition to a balanced diet, not a replacement for medical care.

Note: The studies cited used controlled dosages of bay leaf extract. Homemade tea may deliver different concentrations. Always talk with a healthcare provider before using bay leaf tea to manage a health condition.

What Is Bay Leaf Tea?

Bay leaf tea is an herbal infusion made by steeping dried or fresh bay leaves (Laurus nobilis) in hot water for 5-10 minutes. People drink it for digestive support, blood sugar management, respiratory relief, and inflammation reduction.

The typical preparation involves adding 1-2 dried bay leaves to boiling water, steeping, then straining. While simple to make, bay leaf tea isn’t risk-free.

The same compounds that offer potential benefits can trigger adverse reactions when consumed improperly or by certain individuals.

What Nutrients Are in Bay Leaf Tea?

Bay leaves pack a surprising nutritional punch for such a small ingredient. They contain vitamins A, B6, and C, as well as folate, along with minerals such as iron, calcium, potassium, magnesium, manganese, and zinc.

The leaves are also rich in bioactive plant compounds:

Eugenol acts as a natural anti-inflammatory and antimicrobial agent.

Cineole supports respiratory function and may help loosen congestion.

Linalool has calming, mildly sedative properties.

Myrcene contributes to anti-inflammatory and antioxidant activity.

You won’t get huge amounts of any single nutrient from a cup or two of tea. But the combination of polyphenols, flavonoids, and essential oils is what gives bay leaf tea its potential health benefits.

What Are the Benefits of Bay Leaf Tea?

1. May Support Digestive Health

If you’ve ever felt heavy and bloated after a big meal, bay leaf tea might help. Bay leaves contain enzymes that assist in breaking down proteins and carbohydrates, which can speed up digestion and reduce that uncomfortable fullness.

The compounds cineole and eugenol may help relax the muscles of the gastrointestinal tract, easing gas, bloating, and mild indigestion. Traditional medicine systems have used bay leaf preparations for stomach complaints for centuries.

I started keeping a small jar of dried bay leaves next to my tea stash after noticing how much better my stomach felt on evenings I brewed a cup after dinner. It’s become part of my post-meal wind-down, especially after heavier dishes like stews or pasta bakes.

2. May Help Regulate Blood Sugar Levels

This is one of the most researched potential benefits. A study published in the Journal of Clinical Biochemistry and Nutrition found that participants with type 2 diabetes who consumed 1-3 grams of bay leaves daily for 30 days experienced a 21-26% reduction in fasting blood glucose.

The polyphenols and flavonoids in bay leaves appear to improve how insulin functions in the body. That said, this research used measured doses of bay leaf powder or extract, not homemade tea, so results may vary.

If you have diabetes or take blood sugar medications, talk to your doctor before adding bay leaf tea to your routine. It could amplify the effects of your medication.

3. Contains Anti-Inflammatory Compounds

Chronic, low-grade inflammation is connected to a range of health problems, from joint pain to heart disease. Bay leaves are rich in eugenol, myrcene, and pinene, compounds that research suggests may reduce inflammatory markers in the body.

A cup of bay leaf tea won’t replace an anti-inflammatory diet or medication. But as part of an overall healthy eating pattern, it may provide some additional support.

4. May Provide Respiratory Relief

There’s a reason your grandmother might have added bay leaves to a steaming pot of soup when someone had a cold. Bay leaf’s essential oils, particularly cineole, have expectorant properties that may help loosen mucus and clear congestion.

Some people find that simply inhaling the steam from a fresh cup of bay leaf tea provides mild relief from nasal stuffiness and chest tightness during cold and flu season.

5. Rich in Antioxidants

Bay leaves contain vitamin C, carotenoids, and polyphenolic compounds that act as antioxidants. These molecules help neutralize free radicals, which are unstable compounds that can damage cells and contribute to aging and chronic disease over time.

A 2019 literature review noted multiple potential protective effects from bay leaf antioxidants, though most evidence comes from lab and animal studies rather than large-scale human trials.

6. May Support Heart Health

Several compounds in bay leaves show potential cardiovascular benefits. The potassium content supports healthy blood pressure, while caffeic acid and rutin may help reduce LDL (“bad”) cholesterol levels.

The 2009 Khan et al. study also found that bay leaf consumption improved triglyceride and HDL cholesterol levels alongside the blood sugar improvements. Your heart and your blood sugar tend to be connected, so that’s not a huge surprise.

7. May Help With Stress and Relaxation

Linalool, one of the aromatic compounds released when you brew bay leaf tea, has mild sedative and calming properties. Research on linalool (also found in lavender and basil) suggests it may help reduce stress hormones and promote relaxation.

Drinking a warm cup of bay leaf tea before bed is a common practice in many cultures for a reason. It’s not going to knock you out, but the warmth plus the calming aroma can make a real difference in your nighttime routine.

I’m a big fan of herbal teas before bed, and bay leaf tea has become a regular rotation for me. The aroma alone seems to slow my brain down a bit. Not as floral as chamomile, not as minty as peppermint. More like a warm, earthy hug in a mug.

8. May Have Antimicrobial Properties

Bay leaf essential oils have shown activity against several types of bacteria and fungi in laboratory studies, including Staphylococcus aureus, E. coli, and Pseudomonas aeruginosa.

This doesn’t mean bay leaf tea is an antibiotic. But it suggests that regular consumption could provide some passive support for your body’s defenses, especially during seasons when colds and stomach bugs run rampant.

9. May Support Hair and Skin Health

Bay leaves are a traditional ingredient in hair care across many cultures. The vitamins A and C, along with the anti-inflammatory properties of eugenol, may help soothe scalp irritation and support healthier hair follicles.

Some people also use cooled bay leaf tea as a rinse after shampooing. The antioxidant content may help protect both skin and hair from environmental damage.

10. May Aid Weight Management

Bay leaf tea is virtually calorie-free and may support metabolism and digestion. Some traditional medicine practices recommend it as part of a weight management routine because bay leaf enzymes help break down proteins more efficiently.

There’s no strong clinical evidence that bay leaf tea alone causes weight loss. But if it helps you digest meals better and replaces a high-calorie evening beverage? That’s a practical win.

How Do You Make Bay Leaf Tea?

Making bay leaf tea takes about 15 minutes and requires two ingredients.

Basic Bay Leaf Tea Recipe

Ingredients:

• 2 dried bay leaves (or 3-4 fresh ones)
• 2 cups of water
• Optional: honey, lemon, cinnamon stick, or fresh ginger

Instructions:

1. Bring the water to a boil in a small pot.
2. Add the bay leaves and reduce the heat to a simmer.
3. Let the leaves simmer for 5 minutes to release their essential oils.
4. Remove from heat, cover, and steep for another 5-10 minutes.
5. Strain the tea into a mug (this step is non-negotiable; never drink with leaf fragments).
6. Add honey, lemon, or a cinnamon stick if you like.

Tips for a better brew: Dried leaves tend to produce a more concentrated flavor than fresh ones. Crushing or tearing the leaves slightly before adding them to water helps release more of the aromatic oils. If the flavor is too mild, try simmering for a couple of extra minutes rather than adding more leaves.

My favorite version adds a thin slice of fresh ginger and half a cinnamon stick to the pot. It turns plain bay leaf tea into something that smells like a spice market and tastes like fall in a cup. My wife prefers hers with a squeeze of lemon and a drizzle of honey, which brightens up the earthy flavor.

Does Bay Leaf Tea Have Side Effects?

Bay leaf tea is safe for most people in small amounts. But like any herbal remedy, it’s not without potential downsides. Knowing these side effects helps you enjoy the tea without any surprises.

1. Digestive Irritation

The tannins and essential oils in bay leaves can irritate your stomach lining, especially if you drink the tea on an empty stomach or brew it extra strong.

Symptoms might include mild cramping, nausea, or a burning sensation. Drinking bay leaf tea after a meal rather than before tends to reduce this issue.

2. Drowsiness

Bay leaf contains compounds with mild sedative effects, which is partly why it’s popular as a bedtime drink. The flip side? If you drink it during the day or in larger amounts, it can make you feel sluggish. Avoid combining it with alcohol or sleep medications, as the drowsiness may become excessive.

3. Blood Sugar Drops

The same blood-sugar-lowering properties that make bay leaf tea appealing to some people can backfire for others. If you don’t have blood sugar issues, drinking too much could leave you feeling shaky, irritable, or fatigued.

If you take diabetes medication, the combined effect can cause dangerously low blood sugar (hypoglycemia). Always monitor your levels and talk with your doctor.

4. Allergic Reactions

Some people are allergic to bay leaves and may develop skin rashes, hives, or itching after drinking the tea. If you have allergies to other plants in the Lauraceae family (cinnamon, avocado, or sassafras), you’re at higher risk of cross-reactivity.

Stop drinking the tea immediately if you notice any allergic symptoms and seek medical attention if they worsen.

5. Choking Hazard from Whole Leaves

Bay leaves remain rigid even after steeping in hot water. Whole leaf fragments can scratch your throat or digestive tract, and in rare cases, cause choking. This is why straining your tea thoroughly is non-negotiable. Never swallow whole or partial bay leaves.

6. Overconsumption and Toxicity

Drinking excessive amounts of bay leaf tea, or brewing it extremely strong, can concentrate the essential oils to levels that cause nausea, vomiting, difficulty breathing, or rapid heartbeat.

Stick to 1-2 cups per day using 1-2 dried leaves per cup, and you’ll stay well within safe territory. More isn’t better with herbal teas.

Mild vs Serious Side Effects of Bay Leaf Tea

Bay Leaf Tea Drug Interactions

Bay leaf tea can interact dangerously with several medications. Always consult your healthcare provider before adding it to your routine if you’re taking prescription drugs.

1. Diabetes Medications

Bay leaf tea lowers blood sugar levels, creating a compounding effect when taken with insulin or oral hypoglycemics such as metformin, glipizide, or glyburide.

This combination can cause severe hypoglycemia, resulting in shakiness, confusion, sweating, or loss of consciousness.

Interaction severity: Moderate to high. The Natural Medicines Comprehensive Database rates this interaction as one requiring close monitoring or avoidance.

2. Blood Pressure Medications

The tea may lower blood pressure, potentially creating additive effects with antihypertensive medications, including ACE inhibitors (lisinopril), beta-blockers (metoprolol), and calcium channel blockers (amlodipine).

This can lead to dangerously low blood pressure, causing extreme dizziness, fainting, or inadequate blood flow to vital organs.

3. Sedatives and CNS Depressants

Bay leaf’s natural sedative properties intensify when combined with sleeping pills (zolpidem, eszopiclone), anti-anxiety medications (alprazolam, diazepam), or alcohol.

This increases drowsiness, slows reaction time, and can dangerously depress respiratory function.

4. Blood Thinners

Some evidence suggests that bay leaf may affect blood clotting. If you’re taking warfarin, aspirin, clopidogrel, or other anticoagulants, bay leaf tea could theoretically increase bleeding risk, though research remains limited.

Clinical recommendation: Patients on anticoagulant therapy should inform their healthcare provider before consuming bay leaf tea regularly.

How Much Bay Leaf Tea Is Safe to Drink?

Most herbal references consider 1-2 cups per day a reasonable amount, using 1-2 dried leaves per cup. There’s no FDA-regulated dosage for bay leaf tea because it’s classified as a culinary herb, not a pharmaceutical.

A few practical guidelines: don’t steep with more than 2 leaves per cup, don’t brew for longer than 15 minutes, and always strain thoroughly. Potency varies with leaf age and storage, so start with 1 cup and see how your body responds before making it a daily habit.

Who Should Avoid Bay Leaf Tea

Certain groups face heightened risks when consuming bay leaf tea and should avoid it entirely or use it only under medical supervision.

1. Pregnancy and Breastfeeding

Pregnant and nursing women should avoid bay leaf tea due to insufficient safety data and potential uterine stimulation that could trigger contractions. Bay leaf compounds may pass into breast milk with unknown effects on infants.

The American Pregnancy Association urges moderation with herbal teas lacking robust pregnancy safety data; bay leaf is safe in food amounts, but consult providers for teas.

2. Upcoming Surgery

Stop drinking bay leaf tea at least two weeks before scheduled surgery. It can interfere with blood glucose control during procedures and interact unpredictably with anesthesia, causing excessive sedation or blood pressure changes.

The ASA advises disclosing all herbal supplements before surgery, as they may interact with anesthesia—stop high-risk ones 1–2 weeks prior.

3. Diabetes or Blood Sugar Disorders

People with diabetes should not use bay leaf tea without medical guidance. It causes unpredictable blood sugar drops, especially when combined with diabetes medications, creating a dangerous hypoglycemic risk. Frequent monitoring is essential if approved by your doctor.

4. Known Allergies to The Lauraceae Family

Anyone allergic to plants in the Lauraceae family (cinnamon, avocado, sassafras) should avoid bay leaf tea. Cross-reactivity can trigger reactions ranging from skin irritation to severe anaphylaxis with breathing difficulty and swelling.

Conclusion

Bay leaf tea has earned its reputation as a simple, flavorful herbal drink with real potential. From supporting digestion and blood sugar regulation to providing anti-inflammatory and calming effects, the research and centuries of traditional use both point to genuine value.

The key is moderation and awareness. Stick to 1-2 cups per day, always strain thoroughly, and pay attention to how your body responds. If you take medications for diabetes, blood pressure, or blood clotting, get your doctor’s input first.

For most people, bay leaf tea is a low-risk way to add a little extra support to an already balanced routine. Sometimes the best health boosts come from the most unassuming corners of your spice cabinet.
