Baccharis dracunculifolia is a shrub from the grasslands of Brazil. Locals call it alecrim-do-campo, or false rosemary. Bees collect resin from its leaf buds to make Brazilian green propolis.
It is best known as the plant behind that propolis. On its own, the leaves are sold as a dried tea, a tincture and an essential oil. Extracts also turn up in skin creams and mouth rinses.
Brazilian folk healers used the leaves for stomach complaints, wounds and sore joints. Most of what is sold today leans on that history rather than on trials.
The honest verdict: nearly all the research is lab and animal work. Good human trials on the plant itself are very few. Its benefits in people are not proven.
Long use in folk medicine is not proof that a plant works. It is also not proof that it is safe.
No one has shown how this plant acts in the human body. The proposed ideas all come from test tubes and animals.
In lab tests, extracts mop up free radicals (unstable molecules that damage cells). Artepillin C is the compound most often credited for this. Whether that matters once you swallow a tea is not known.
In mice and rats, extracts have reduced swelling and have protected the stomach lining from alcohol and drug damage. These are animal results. They do not tell you what happens in a person.
In test tubes, the oil and the extract slow the growth of some bacteria and fungi. That includes bugs linked to tooth decay and gum disease. Whether this happens in a real mouth is still open.
A few lab studies report effects on cancer cells in a dish. Cells in a dish are not people, and no trial shows the plant treats cancer in anyone.
You will meet it in a handful of forms.
- Dried leaves for tea or infusion. - Alcohol tinctures and liquid extracts. - Capsules, often sold as Brazilian green propolis rather than under the plant name.
- Essential oil, for scent and skin products only. - Gels, creams, toothpastes and mouth rinses.
Green propolis is a bee product, not the raw plant. It contains wax and bee material as well as plant resin. People allergic to bee products need to treat it as a bee product.
Strengths are not standard across brands. A tea and a concentrated extract are not swappable.
The plant has a long record in Brazilian country medicine. Healers in Minas Gerais and the cerrado region used leaf teas and poultices.
Recorded folk uses included stomach upset, liver complaints, wounds, ulcers and aching joints. The leaves were also burned or steeped for their scent.
Its modern fame came through beekeeping. From the 1980s, Brazilian green propolis built a large export market, mostly to Japan. That trade drove most of the chemical research on the plant.
This history explains why the plant is popular. It does not tell you that the old uses worked.
Stop using it and get medical help straight away if your lips, face or throat swell, or you struggle to breathe. That is an emergency.
Stop and see a doctor if you get a spreading rash, blisters or bad itching.
See a doctor if stomach pain, black stools, vomiting or yellow skin or eyes appear.
Also book an appointment if the problem you are treating has not improved in about two weeks.
In the United States and the United Kingdom it is sold as a dietary supplement or a cosmetic ingredient, not as an approved medicine. In Brazil, green propolis from this plant is a regulated food product with export standards.
