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 studies actually show: small, short trials, mostly in people without diabetes, 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
A small number of studies, most involving a handful of participants over a few weeks, have looked at bay leaf, Laurus nobilis, and its effect on blood sugar markers. Some found modest improvements in fasting glucose in people with prediabetes or mild insulin resistance when bay leaf was added to the diet for a month. These are genuinely interesting early findings, not proof of a therapeutic 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 once a day alongside medical care Depends
2 to 3 leaves boiled in 2 cups of water for 5 to 10 minutes, strained and drunk warm, once daily.
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. One cup a day, 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 once daily, ideally alongside a meal, as a 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 some early research suggests a possible mild effect on clotting, and this deserves a doctor’s input if you are on 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.

Does bay leaf water lower blood sugar?
Small studies suggest a possible modest effect in people without diagnosed diabetes. It is not a proven treatment and should never replace prescribed medicine.
Can I stop my diabetes medicine if I drink bay leaf water?
No. Medication should only be changed by your doctor based on blood test results, never based on a home remedy or how you feel.
Is tej patta the same as bay leaf?
Often not exactly. Tej patta is commonly a different, related species to the Mediterranean bay leaf used in much of the research, though the two get used interchangeably in kitchens.
Is it safe to drink bay leaf water every day?
In modest amounts, generally yes for most healthy adults, though anyone on blood thinners or diabetes medication should check with a doctor first.
