Bay Leaf (Tej Patta) Water for Diabetes: The Claim Checked
A forwarded message claims boiling three tej patta leaves and drinking the water every morning “controls sugar naturally” and might even let you cut back on medicine. Someone’s uncle tried it, felt fine, and stopped taking his tablet. That last part is the dangerous sentence in this whole trend, and it deserves to be addressed before anything else about the leaf itself.
Quick facts
- What the evidence looks like: a few small, short trials, mostly in people without diabetes, with mixed results
- What it does not do: replace insulin or diabetes medication, ever
- Biggest real danger: stopping or reducing prescribed medicine because of this claim
- Safe as a habit: yes, as a food and occasional drink, alongside medical care, not instead of it

What the actual research says
Bay leaf, Laurus nobilis, has been tried in a few small, short trials looking at blood sugar markers, with mixed results. That’s limited evidence, not proof of any effect for people with diagnosed diabetes. The trials are small, short, and mostly not designed the way a real medical trial for a diabetes treatment would need to be. That gap between “an interesting small study exists” and “this controls your sugar” is exactly where the forwarded message goes wrong.
The confusion between tej patta and true bay leaf
Tej patta, the leaf used in South Asian cooking, is often Cinnamomum tamala, a cassia-cinnamon relative, and not the same species as the Mediterranean bay leaf, Laurus nobilis, that most of the international research is actually studying. They look broadly similar and get used interchangeably in kitchens, but they are botanically different plants with somewhat different compound profiles. Some of the circulating claims quietly borrow research done on one leaf and apply it to the other, which is worth knowing before treating any specific number from a study as directly relevant to your kitchen’s tej patta. Our bay leaf and tej patta guide covers the difference between the two leaves in full.
A small study on a related leaf is not a green light to stop your medicine.
Adding tej patta to daily cooking Worth It
1 to 2 leaves added to dal, rice or curry as usual, removed before eating.
Perfectly reasonable as ordinary food. It adds flavour and, at worst, does nothing measurable for blood sugar. There is no downside to continuing to cook with it exactly as your kitchen already does.
Drinking boiled bay leaf water now and then alongside medical care Depends
2 to 3 leaves boiled in 2 cups of water for 5 to 10 minutes, strained and drunk warm.
Depends on keeping it in its proper place, as a food-level habit alongside prescribed treatment, not a replacement for it. If you enjoy the taste and want to try it as an addition, there is little harm for most healthy adults, but it should never be the reason you skip a dose or a doctor’s visit.
Reducing or stopping diabetes medication because of this drink Skip It
Cutting back on insulin, metformin, or any prescribed diabetes medicine based on how this drink makes someone feel.
Skip this entirely, without exception. Diabetes medicine dosing is managed by blood test results and a doctor’s judgement, not by symptoms alone, since blood sugar can feel fine while still being dangerously high or dangerously low. Stopping medicine on the strength of a forwarded message has led to real, documented harm, from uncontrolled blood sugar to dangerous swings when medicine is resumed incorrectly.
Drinking it in large amounts, several cups a day Skip It
Some versions of the claim suggest drinking multiple cups through the day for a “stronger effect”.
Skip. There is no dose-response evidence supporting more being better here, and bay leaf in concentrated form has been linked to mild digestive upset in some people at higher intake. An occasional cup, if you choose to have it at all, is plenty.
What a genuine food-level addition looks like in practice
People who tolerate this drink well tend to treat it exactly like an extra cup of unsweetened herbal tea, one that happens to have a mild, pleasant, slightly spiced taste. It fits naturally after a meal, alongside the ordinary evening cup of chai many households already make, rather than replacing anything medical in the routine. Framed that way, there is nothing wrong with it. The trouble starts only when it gets reframed as treatment rather than habit, and that reframing is entirely a marketing choice, not something the leaf itself supports.
Why the “my uncle felt fine and stopped his tablet” story is misleading
Type 2 diabetes often has no noticeable symptoms even when blood sugar is significantly elevated, which is precisely why regular blood tests, not how someone feels, are used to manage it. Feeling fine after stopping medicine and drinking bay leaf water for a few weeks is not evidence the leaf replaced the medicine. It is, more often, a coincidence of a condition that does not always announce itself until complications appear later, sometimes as vision changes, kidney strain, or a slow-healing wound.
Both Ayurveda and Unani tradition include aromatic leaves and barks like tej patta in formulations described as balancing digestion and supporting general wellbeing, always as part of a broader dietary approach rather than a single-leaf cure. Traditional use of a food as generally beneficial is a fair description. Traditional use has never meant a substitute for managing a diagnosed medical condition, and conflating the two does a disservice to the tradition as much as to the person relying on it.
- Take 2 to 3 dried tej patta leaves and rinse briefly.
- Boil in 2 cups (about 500 ml) of water for 5 to 10 minutes.
- Strain and let cool to a warm, drinkable temperature.
- Drink it warm, ideally alongside a meal, as an occasional food-level addition only.
Never adjust, reduce or stop insulin or any diabetes medication without your doctor’s explicit instruction, based on blood test results, not on symptoms or a home remedy. Anyone on blood thinners should be cautious with bay leaf in concentrated amounts, since it may have a mild effect on clotting, though the evidence is limited, so ask your doctor first if you take such medication. Symptoms like excessive thirst, frequent urination, blurred vision, unexplained weight loss, or slow-healing wounds need proper testing, not a home drink, whether or not you already have a diagnosis.
Cook with it, enjoy it, even drink it as a warm addition to your day if you like the taste. Never let it stand in for a blood test or a prescribed medicine.

Tej patta water and diabetes doubts
Does bay leaf water control blood sugar?
It isn’t a way to control diabetes. A handful of small, short trials, mostly in people with prediabetes rather than diagnosed diabetes, found modest changes in fasting glucose, with mixed results overall. That’s an interesting early finding, not a treatment, and it never replaces your prescribed medicine.
Can I stop my diabetes medicine if I drink tej patta water?
No, and this is the part of the trend that causes real harm. Insulin, metformin or any sugar tablet should only be changed by your doctor based on blood tests. Sugar can feel fine while being dangerously high or low.
My relative stopped his tablet and feels fine. Doesn’t that prove it works?
Sadly not. Type 2 diabetes often has no symptoms even when sugar is well above target, which is why it’s managed by blood tests, not by how someone feels. Damage can build quietly and show up later as vision changes, kidney strain or slow-healing wounds.
Is tej patta the same as bay leaf?
Often not. The tej patta in desi kitchens is usually Cinnamomum tamala, a cassia relative, while most of the research looked at Mediterranean bay leaf, Laurus nobilis. They look alike and get swapped in cooking, but they’re different plants, so study figures for one don’t automatically apply to the other.
How do you make bay leaf water?
Rinse 2 to 3 dried leaves, boil them in 2 cups (about 500 ml) of water for 5 to 10 minutes, strain and drink it warm. Treat it like an unsweetened herbal tea, ideally alongside a meal, and as a food habit only.
Is it safe to drink bay leaf water every day?
One cup a day is generally fine for most healthy adults as a food-level habit alongside proper care. More isn’t better, though. There’s no evidence several cups add anything, and concentrated amounts can upset some people’s stomachs.
Can I drink tej patta water if I’m on blood thinners?
Ask your doctor first if you take warfarin or another blood thinner, since early research hints bay leaf might have a mild effect on clotting.
Is it fine to keep using tej patta in cooking?
Absolutely. A leaf or two in dal, rice or salan, removed before eating, is ordinary food with no downside.
What signs mean I should get my sugar tested?
Excessive thirst, passing urine often, blurred vision, unexplained weight loss or wounds that heal slowly all need a blood test, not a home drink. A fasting sugar of 126 mg/dL or HbA1c of 6.5% is the line doctors use to diagnose diabetes.
