Baccharis articulata is a small South American shrub drunk as a bitter tea, mostly for digestion.
In Brazil, Argentina, Uruguay and Paraguay it is called carqueja or carquejilla. The dried stems are steeped in hot water. The plant has flat green winged stems that do the job of leaves.
Several Baccharis species share the carqueja name. That makes shop labels hard to trust. One relative, Baccharis coridifolia, is poisonous.
Here is the honest verdict. Human evidence is very thin. Almost everything known comes from test tubes, rats and mice.
Long folk use is not proof that a plant works. It is also not proof that it is safe. That point is made once here and not repeated below.
No one has shown in people how this plant works, or that it works at all.
In animal studies, extracts of Baccharis articulata have lowered blood sugar. Related carqueja species have done the same in rats. These results do not tell you what a cup of tea does in a person.
In test tube work, the plant's flavonoids mop up free radicals (unstable molecules that can damage cells). Lab tests also suggest the extract may slow some bacteria and some gut enzymes.
Whether any of that happens inside your body is not established.
The older folk idea was simpler. Bitter plants were thought to wake up the stomach. Bitter tastes can raise saliva and digestive juices, but this has not been measured for this plant.
It is sold mainly as a dried herb for tea.
- Loose dried stems, cut or powdered. - Tea bags, often blended with other herbs. - Tinctures and liquid extracts in alcohol.
- Capsules of dried powder or dry extract. - A bitter flavour in some regional drinks and spirits.
In southern Brazil and Uruguay, a pinch is sometimes added to mate. The essential oil is not a home product and should not be swallowed.
Buy from a seller that names the species on the label. Carqueja products often contain Baccharis trimera instead, or a mix.
Carqueja has a long record in South American folk medicine.
Guarani and later settler healers used the bitter tea for the stomach and liver. Writers in the 1800s and 1900s listed it as a digestive and a "blood cleanser". Later folk use in Brazil and Argentina added sugar problems and gout.
It also became an everyday home drink, not only a remedy. People took it after heavy meals.
This history explains why the plant is still popular. It does not tell you what the tea does in your body.
Stop and see a doctor if you get shaky, sweaty or confused, which can mean low blood sugar.
Also stop and get checked if you notice:
- Yellow skin or eyes, dark urine, or pain under your right ribs. - A rash, swollen lips or tongue, or trouble breathing. Treat breathing trouble as an emergency and call for help. - Stomach pain or diarrhoea that lasts more than a day or two.
See a doctor rather than self-treating if you have ongoing indigestion, weight loss, or a known liver or sugar problem.
In Brazil, carqueja is a well known herbal tea, and ANVISA lists carqueja (mainly Baccharis trimera) among traditional herbal products. In the United States and the United Kingdom it is sold as a food supplement, not an approved medicine. No regulator has approved Baccharis articulata to treat any illness.
