What it is
Tej patta, also called tejpat or Indian bay leaf, is the leaf of Cinnamomum tamala, a tree in the laurel family. [1] It grows wild in northern India (Assam and the western Himalayas), Nepal, Bangladesh, Myanmar and nearby countries, and can reach about 20 m tall. [1] The word comes from Sanskrit. [1]It is not the same plant as the bay leaf of Mediterranean cooking, Laurus nobilis. [1][2] Tej patta leaves are about twice as long and wide, usually olive green, with three veins running along the leaf instead of one. [1][2] Shops often sell it as just "bay leaf", which causes mix-ups. [1] It also has other English names, including Indian cassia and Malabar leaf. [1]
Flavor and aroma
Tej patta tastes and smells like cassia (cinnamon) bark, but milder. [2] Another description is a clove-like smell with a hint of pepper. [1] Western bay leaf leans more toward pine and lemon. [1]The sources we read name several aroma compounds in the leaf, including beta-caryophyllene, linalool and eugenol (the main clove compound). [1] They give no percentages, and one source says leaves come in several grades with different cinnamon-like or cassia-like profiles. [1] A laboratory test of one leaf extract found 3.8% eugenol by weight, but that was a concentrated extract, not a cooking leaf. [4] The sources do not say how heat changes the flavor.
How it is used in cooking
Cooks use the whole leaf, usually dried, and take it out before serving (our reading of the bay-leaf safety advice). [2] The leaf is a background flavor, not the main one. The sources we read do not say whether it should be toasted or when to add it, so we give no rules here.- North Indian cooking: it is used widely in Indian and Nepali cooking, and especially in Mughal-style dishes. [1]
- Rice dishes, dal and spice mixes: seller and forum pages in our search results mention biryani, pulao, dal, kormas and garam masala. We did not open them in full, so we do not cite them.
- Bhutan: the leaves go into a herbal tea called tsheringma. [1]
Substitutes: Western bay leaf is sometimes used in place of tej patta, mainly in biryani and garam masala, but the flavor is different. [2]
Normal food amounts
USDA FoodData Central (SR Legacy, 2018) has no entry for Indian bay leaf, so we give no gram weights or nutrient numbers. Its "bay leaf" entry is for the common spice and we did not assume it matches this one.| Measure | Grams | Source |
|---|---|---|
| 1 teaspoon, crumbled | Not available | USDA SR Legacy has no entry |
| 1 whole leaf | Not available | We opened no source with a weight |
| Typical recipe amount | Not found | No source we opened states an amount |
Buying, storing and preparing
- Forms: whole dried leaves are the usual form. Bark of the same tree is sometimes used like cinnamon but is considered inferior to true cinnamon or cassia. [1]
- What to look for: a leaf that is long, olive green and has three clear veins. A small, pale leaf with one central vein is Western bay. [1][2]
- Label check: "bay leaf" alone does not tell you which plant you are buying. [1] Look for the Latin name or "tej patta" on the pack.
- Storing and shelf life: the sources we read give no shelf life. A cool, dry, closed container is the usual sensible choice for dried leaves.
- Grinding: the sources we read do not describe grinding this leaf. Ground Western bay leaf is much stronger than whole leaf, so do not assume the same for tej patta. [2]
Health: what research says
Eating a leaf that is simmered and removed is very different from taking an extract. For tej patta, almost all the research we found is on extracts in animals or in the lab. [3]Food amounts vs supplements
| In normal cooking | In supplements and extracts | |
|---|---|---|
| Typical amount | No source we opened states an amount | No official or trial amount found |
| What studies mostly used | We found no study of the leaf as eaten in food | Ethanol or methanol leaf extracts, in rats or in lab dishes [3][4][5] |
| What we can say about benefit | Nothing; no human data found [3] | Nothing for people; animal and lab findings only [3] |
| Main safety limit | Do not swallow stiff leaf pieces [2] | No human safety data found for tej patta [3] |
What the evidence shows
| Use | What the sources found | Strength of evidence | Form and population |
|---|---|---|---|
| Blood sugar | An ethanol leaf extract lowered blood glucose in rats made diabetic, and so did leaf essential oil. A 2021 review found no human trial of this species. [3] | Lab or animal only | Extract or oil; rats [3] |
| Diarrhoea | A 50% ethanol extract reduced castor-oil diarrhoea in rats. The authors concluded it is useful, but this was rats only. [4] | Lab or animal only | Standardised extract; rats [4] |
| Germ-killing action | A methanol extract was active against Staphylococcus aureus in a lab dish. [5] A bark extract needed fairly high concentrations. [3] | Lab or animal only | Extract; test tubes, not people [3][5] |
| Antioxidant activity | An ethanol extract was active in lab antioxidant tests. [3] | Lab or animal only | Extract; test tubes [3] |
| Any use of the leaf in cooking | No study found | Insufficient evidence | Food amounts |
The animal doses are far from a leaf in a pot, and findings in rats often do not hold in people.
Official statements
We opened no EMA, EFSA, FDA, WHO or NCCIH statement about Cinnamomum tamala, so we cite none. The IUCN Red List rates the species Least Concern, as reported on the Wikipedia page. [1]Related pages

Body systems (2)
- Blood Sugar SupportLab or animal research only
Rats made diabetic had lower blood glucose after a leaf extract or leaf oil; no human trial of tej patta was found.
- Digestive SystemLab or animal research only
A leaf extract reduced experimental diarrhoea in rats; no human data. Separately, stiff whole leaves can harm the gut if swallowed.
Body parts (1)
- GutDocumented risk
Stiff whole bay leaves, if swallowed whole or in large pieces, may harm the digestive tract or cause choking.
Functional actions (2)
- AntioxidantLab or animal research only
Extracts were active in lab antioxidant tests; this does not show a benefit in people.
- Blood Sugar RegulationLab or animal research only
Animal findings only.
Root causes (1)
- Blood Sugar ImbalanceLab or animal research only
Only animal findings of lower glucose; nothing in people.
Documented risks and interactions (3)
- Choking and gut injury from swallowing stiff leaves. Bay leaves in general stay stiff after cooking; swallowed whole or in large pieces they may harm the digestive tract or cause choking.
- Coumarin and other cinnamon-genus cautions (not measured for this leaf). A review says coumarin in some cinnamon species may harm the liver and lists possible drug interactions for cinnamon in general; it gives no figure for tej patta.
- Mix-ups with other bay leaves. Tej patta is often sold as plain bay leaf, so the plant bought may not be the one intended.
Frequently asked questions
Is tej patta the same as bay leaf?
No. Tej patta is the leaf of Cinnamomum tamala, a cinnamon-family tree. Common bay leaf comes from Laurus nobilis. [1][2]
Does it taste like cinnamon?
Yes, like mild cassia cinnamon, with a clove-like edge. [2][1]
How much is normal?
We found no source that states an amount, and USDA has no entry. The leaf is removed before eating.
Is it safe in pregnancy?
The sources we read do not describe pregnancy safety for tej patta. Ask your midwife or doctor, especially about supplements or extracts.
Can I take it with medicines?
We found no interaction data for this leaf. If you are thinking of an extract or supplement, ask a pharmacist first. [3]
Can I use ordinary bay leaf instead?
Cooks do, mainly in biryani and garam masala, but the flavor is different. [2]

Safety note at a glance
Safety in more detail
- Medicines: the sources we read describe no interactions for tej patta. A review lists possible interactions for cinnamon in general, including with diabetes medicines, statins and some other drugs, but it does not tie them to this leaf. [3]
- Pregnancy: the sources we read do not describe pregnancy safety for tej patta.
- Breastfeeding: the sources we read do not describe this.
- Children: the sources we read do not describe this.
- Allergy: the sources we read do not describe allergy to this leaf. Cinnamon oil on the skin can cause redness, irritation and burning. [3]
- Liver and kidney: the same review says coumarin in some cinnamon species may harm the liver. [3] It gives no coumarin figure for tej patta, and we did not find one, so we cannot say how much this leaf contains.
- Surgery: the sources we read do not describe a surgery warning. Tell the surgical team about any supplement.
- Quality and contamination: the sources we read give no contamination data for tej patta. The main practical issue is mix-ups with other "bay" leaves. [1]
- Amounts that cause trouble: not described for the leaf in food. The choking and gut-injury risk of stiff whole leaves is documented for bay leaves in general. [2]
