Tamalpatra (Indian Bay Leaf) in Ayurveda: Properties & Everyday Use

In short

Tamalpatra, known as Indian bay leaf in English and tej patta in Hindi, is a familiar part of the Indian kitchen. Classical Ayurveda describes it as bitter and pungent in taste, light in quality, and warming by nature. Indian bay leaf is added whole to rice dishes and curries.

In your kitchen

  • One leaf goes into the ghee at the start of a pulao.
  • As a warming food, tradition leans on it more in the cooler months.

Good to know

In everyday food amounts it is part of ordinary home cooking. If you're pregnant, nursing or take regular medication, check with your doctor before using it beyond normal food amounts.

What it is

Tamalpatra is Cinnamomum tamala (Buch.-Ham.) Nees & Eberm., a multipurpose evergreen tree of the laurel family (Lauraceae), native to India: mainly the moist slopes of the Himalayan regions at 900–2,500 m altitude (Tiwari & Talreja, Pharmacogn J 2020). It grows 7–12 m tall with dark brown to reddish-brown bark; the leaves are thickened, ovate, and glossy, with a clove-like taste and pepper-like odor (same review). In Sanskrit it is Tamalpatra, in Hindi Tejpatta, and in English Indian bay leaf or Indian cassia (same review). Leaf oil contains cinnamaldehyde, eugenol, linalool, 1,8-cineole, and related aromatic compounds (same review).

Classical properties

Traditional use

In Ayurveda, tejpatta leaves are used in classical formulations including Sudarshan choorna and Chandraprabhavati (Tiwari & Talreja 2020). Traditional indications listed in reviews include flatulence, anorexia, liver and spleen complaints, bleeding disorders, and cardiovascular support (same review). The leaves and bark are described as aromatic, astringent, stimulant, and carminative, used in the Indian systems of traditional medicine for rheumatism, colic, diarrhea, nausea, and vomiting. Seeds crushed with honey or sugar were given to children for dysentery or cough (therapeutic review of C. tamala). The dried leaves are also one of India's most common cooking spices (Tiwari & Talreja 2020). These are traditional uses, not clinical proof.

What research has looked at

No human clinical trials of C. tamala were found in the sources reviewed. The research base is preclinical:

Blood sugar (animal studies)

An ethanolic extract of the leaves showed hypoglycaemic activity in animal models, described as increasing insulin levels and improving oral glucose tolerance (Tiwari & Talreja 2020). This is an animal finding, not evidence that the leaf lowers blood sugar in people.

Kidney protection (animal study)

In rabbits with gentamicin-induced kidney damage, leaf extract showed a protective effect on renal function, blood urea nitrogen, serum creatinine, and urinary protein markers, versus gentamicin alone (Tiwari & Talreja 2020). Again, an animal model, not a human treatment.

What the evidence does not support (yet)

Reviews also list antioxidant, anti-inflammatory, antimicrobial, and cell-level anticancer activities (Tiwari & Talreja 2020): but these come from laboratory and animal studies. None of this has been tested in people, so medicinal claims for diabetes, kidney disease, or any other condition are ahead of the data.

Safety notes

Tamalpatra has a long history of use as a food spice, which speaks to culinary safety: but that is not the same as medicinal-dose safety. No dedicated human safety trials of medicinal doses were found in the sources reviewed. Anyone who is pregnant, breastfeeding, managing a medical condition (especially diabetes, given the animal blood-sugar findings), or taking prescription medicines should consult a qualified practitioner before using it in medicinal amounts.

FAQs

What does "tamalpatra" mean?

Tamalpatra is the Sanskrit name for the leaves of Cinnamomum tamala; the review also lists the English names Indian bay leaf and Indian cassia, and Hindi tejpatta (Tiwari & Talreja 2020). Check the Latin name on the label so you know which plant you are buying.

Does tamalpatra lower blood sugar?

Only in animals so far: an ethanolic leaf extract showed hypoglycaemic activity in animal models (Tiwari & Talreja 2020). No human trials have tested this.

Is Indian bay leaf safe in food?

It is one of India's most widely used cooking spices (Tiwari & Talreja 2020), and culinary use has a long history. Medicinal-dose safety in humans has not been studied.

Are there any human studies on tamalpatra?

None were found in the sources reviewed. All reported pharmacological effects, blood-sugar, kidney, anti-inflammatory, and antimicrobial, come from animal or laboratory studies (Tiwari & Talreja 2020).
