Laurel here means Litsea glaucescens, the Mexican bay leaf. It is a small evergreen tree of Mexico and Central America. Its dried leaves flavour beans, soups, stews and broths.
The same leaf was brewed as a tea in Latin American folk medicine. People drank it for upset stomach, nerves and coughs. Traditional use is not proof that a remedy works, and it is not proof that it is safe.
The honest verdict on evidence: there are almost no human trials of this plant. Most findings come from test tubes and animals. Eating it as a seasoning has a long, calm track record.
Strong teas, extracts and the essential oil are a different question. They are far more concentrated than a leaf in a pot of beans. That is where the real cautions on this page sit.
Mexican laurel is often confused with Mediterranean bay (Laurus nobilis). The two taste alike and are both sold as laurel. Studies on one do not automatically apply to the other.
No mechanism for this plant has been confirmed in people. What follows comes from the laboratory and from animal tests.
In mice, leaf extracts have produced calming and antidepressant-like behaviour. Researchers link this to linalool, the main scent compound. Whether a cup of tea does anything similar in a person is unknown.
In test tubes, the essential oil slows the growth of some bacteria and fungi. That is a dish, not a human infection. It does not make the leaf a treatment for infection.
In animal studies, extracts have eased gut spasms and reduced signs of swelling. These effects are modest and unproven in people. Tradition got there first, but tradition is not a test.
Most people meet laurel as a kitchen herb.
Common forms:
- Whole dried leaves, sold loose or in bags. - Ground or powdered leaf, used as a spice. - Tea or infusion made from one or two dried leaves.
Two other forms turn up:
- Essential oil, sold for scent and massage blends. - Fresh branches, sold in Mexican markets and used for wreaths.
Tinctures and capsules exist but are uncommon. Products are rarely tested for strength. The label may not say which Litsea or Laurus species is inside.
Laurel has long standing in Mexican and Central American home medicine. Market herbalists sold it for stomach trouble, nerves and chills. It appears in colonial-era records and in later Mexican herbal catalogues.
Cooks used it the way Mediterranean cooks use bay. It went into pots of beans, moles, pickles and broths. The culinary use and the home-remedy use ran side by side.
The branches also carry religious meaning. They are cut for Palm Sunday and for festival decorations. Heavy wild cutting is one reason the species is now protected in Mexico.
None of this history tells you whether a tea will help you, and none of it was written as safety testing.
When to see a doctor:
- Go to an emergency department if you swallow a whole leaf and get chest pain, belly pain, trouble swallowing, or you vomit blood. - Call emergency services for swelling of the lips, face or throat, wheezing or trouble breathing. - Get urgent help if a child swallows the essential oil, or if anyone becomes very drowsy or confused after it. - See your doctor if a rash spreads or does not settle after you stop. - See your doctor if you have diabetes and get shaky, sweaty or confused while using strong teas. - Book an appointment if stomach pain, a cough or low mood lasts more than two weeks.
In the United States, the European Union and Mexico, laurel leaf is sold as an ordinary food herb and spice. It is not approved as a medicine anywhere, and no health claim is authorised for it.
In Mexico, Litsea glaucescens is listed as a threatened species under NOM-059, so wild cutting and trade are regulated.
