Mountain tea is a herbal tea made from the dried flowering tops of Sideritis scardica. In Bulgaria it is called mursalski chai. It is drunk as a mild, hay-scented brew, much like chamomile.
The plant grows wild on dry, rocky slopes in the Balkans. Greek, Bulgarian and North Macedonian households drank it for colds, coughs and upset stomachs. Long use is not proof that it works, and it is not proof that it is safe.
Here is the short verdict. Good human trials are missing, so the health claims stay unproven. As an everyday tea, it seems to be well tolerated by most adults.
People also drink it simply because they like it. It has no caffeine. That makes it a common evening drink in the region.
No one has shown clearly how mountain tea acts in the body. Almost all of the claims come from lab work, not from people.
In test tubes, extracts slow the reuptake of serotonin, noradrenaline and dopamine. These are brain chemicals linked to mood and focus. Whether a cup of tea does this in a person is unknown.
In cell and animal studies, its flavonoids appear to damp down inflammation. Animal work also hints at a calming effect. Some animal studies suggest it may protect brain cells.
None of that has been confirmed in people. Treat it as a lead, not as a finding.
The old use for coughs is often put down to the warm drink itself. Warm fluids do soothe a sore throat. That comfort is real, but it is not special to this plant.
Some lab reports also show the extract slowing bacteria in a dish. Skin and gut are very different from a dish. There is no evidence it treats an infection in a person.
Mountain tea is sold mostly as the dried herb. Whole stems with flowers still attached are the traditional form.
Common forms include:
- Loose dried flowering stems, bundled or cut. - Tea bags, often blended with other herbs. - Capsules holding a dry extract, sold for memory or mood.
- Liquid extracts and tinctures in alcohol. - Ready-made iced teas and honey blends in Balkan shops.
The tea and the capsule are not the same product. Capsules may be many times stronger than a cup. Most of the long record of safe use sits with the plain tea, not with concentrated extracts.
Labels sometimes say only "Sideritis" or "Greek mountain tea". Several related species are sold under those names.
Mountain tea has a long, well-documented place in Balkan and Greek folk life. Villagers in the Rhodope and Pirin mountains gathered it in summer and dried it for winter.
It was taken as a hot drink for colds, coughs, sore throats and chest complaints. Families also used it for upset stomachs and for general tiredness. In parts of Bulgaria it carried a reputation as a drink of long life.
It was offered to guests and drunk daily, not only when someone was ill. That everyday, food-like use is part of why it is seen as gentle.
Heavy wild picking has put pressure on the plant. Protected status and farm growing were brought in to help the wild stands recover.
When to see a doctor:
- Stop and get urgent help if you get a rash, swelling of the lips or face, or trouble breathing. - See a doctor if a fever lasts more than three days, or if you cough up blood. - See a doctor if a cough lasts more than three weeks, or if you are short of breath. - See a doctor if low mood, hopelessness or anxiety is affecting your daily life. - See a doctor about any new or worsening memory trouble, rather than treating it yourself. - Stop the tea and ask a pharmacist if stomach upset keeps coming back.
In the European Union, mountain tea is sold as an ordinary food and herbal tea. Mursalski chai has protected regional status in Bulgaria, and wild picking is restricted to protect the plant.
In the United States it is sold as a dietary supplement. The FDA does not approve it to treat or prevent any illness.
