Tila, also called tilo, is the dried flower of the Mexican linden tree (Tilia mexicana). It is brewed as a mild tea. People drink it for nerves, worry, trouble sleeping and the aches of a cold.
It is one of the most common calming teas in Mexico and Central America. You can buy it loose in markets, in tea bags, and in drops. It is close kin to European linden (Tilia cordata), used the same way.
Here is the honest verdict. Human studies on tila are few and small, so its calming effect is not proven. Long traditional use tells you people valued it; it does not prove that it works, and it does not prove that it is safe.
One point matters before you buy. In Mexican markets, "tila" is sometimes a different plant, Ternstroemia pringlei, which is not the same and is harder to judge for safety.
No one has shown in people how tila works, or that it works at all.
In mice, extracts of Mexican linden flower reduce signs of anxiety and shorten the time to fall asleep. In lab binding tests, some of its flavonoids attach to GABA-A receptors. These are the same brain docking points that calming drugs act on.
That is animal and test-tube work. It cannot tell you what a cup of tea does in a person.
The flowers also hold mucilage, a slippery gel-like fibre. In theory this coats a sore throat, which may explain the soothing feel. That idea has not been tested in a trial.
Tradition also calls tila a sweat-promoting tea for fevers. Warm fluid of any kind can do some of that, so the plant may not be doing the work.
Tila is sold in a few simple forms:
- Loose dried flowers and bracts, by weight, in markets and herb shops. - Tea bags, often blended with chamomile, lemon balm or orange blossom (azahar).
- Liquid extracts and tinctures in dropper bottles. - Capsules, less often. - Ready-to-drink bottled teas in some countries.
Hot water infusion is by far the most common use. Check the label for the botanical name. Bags marked only "tila" may contain European linden or Ternstroemia pringlei instead.
Tila has been part of Mexican home and market herbalism since at least the colonial period. Spanish settlers knew European linden tea, and native Tilia species took its place.
Healers and home cooks gave it for susto (fright), nervios (nerves), sleeplessness and headache. It was also brewed for fevers, coughs and colds, often with honey.
It appears in Mexican pharmacopoeias and in the herbal lists kept by public health bodies. It remains a staple of market stalls and kitchen cupboards today.
This is a record of use, not a record of testing.
Stop and get urgent help if you get a rash, swelling of the lips, face or tongue, or trouble breathing. Those are signs of a serious allergic reaction.
See a doctor if your anxiety, sleep problem or headache lasts more than a few weeks. See a doctor for a fever above 39C, a fever lasting more than three days, or a fever in a baby.
Tell your doctor or pharmacist you drink tila if you take daily medicine, especially anything for sleep, mood or blood clotting.
In Mexico, tila is sold freely as a herbal tea and traditional remedy. In the United States it is a dietary supplement or food tea, and is not approved by the FDA to treat any illness. In the European Union, linden flower (from Tilia species) is registered as a traditional herbal medicine, approved on long use rather than on trial results.
