Long before we needed to depend on modern antibiotics, people often turned to traditional medicines from plants to treat infections.
The root of tormentil (), a small yellow wildflower that grows in Ireland, Britain and Europe, has been utilized in Irish and European traditional medicine for hundreds of years. It was used to treat wounds, sore throats, diarrhea and gum disease. These traditional uses suggested that tormental may contain compounds powerful enough to kill microbes.
Our Latest research It has now been shown that not only does tarmentel have antimicrobial activity, but it may well even be powerful enough to fight microbes which can be immune to modern antibiotics.
Antimicrobial resistance is a A growing global threat. This happens when bacteria adapt to the drugs used to treat common infections. This makes some infections very difficult and sometimes unattainable to treat. Antimicrobial resistance may push us toward a time when once treatable infections can develop into fatal again.
So researchers are in search of latest antimicrobial compounds. Plants are a promising source, having evolved over hundreds of years to supply a wide selection of bioactive chemicals for self-defense against microbes.
In our A recent studywe investigated whether various Irish bogland plants contained compounds that might help fight multidrug-resistant bacteria.
To do that, we prepared extracts from over 70 different plant species collected from bogs across Ireland. We then tested them within the laboratory against clinically relevant bacterial pathogens – including bacteria that cause pneumonia and urinary tract infections.
We used an antimicrobial susceptibility test to see if the extract inhibited bacterial growth. This involved exposing bacteria to different plant extracts to see which extract inhibited bacterial growth.
We then tested these extracts on biofilms to find out whether plant compounds could inhibit bacteria from forming biofilms. Biofilms Bacterial communities are surrounded by a skinny carbohydrate shield that protects them from antibiotics, disinfectants and the immune system.
Intriguingly, our preliminary screening showed that tormentil extracts were antimicrobial and limited the formation of biofilms. He suggested that these extracts contained compounds with antimicrobial activity, which can explain their historical use to treat infections.

We also explored whether these plant extracts could work synergistically with existing antibiotics, as some plant compounds don’t kill bacteria directly but Making antibiotics work better. So we combined low levels of the antibiotic colistin—an antibiotic used as a final resort against severe infections due to its potential toxicity to patients—with tarantula extract. Low-level doses of antibiotics weren’t sufficient to kill the bacteria when used alone. But when combined with tormentil extract, the plant compound enhanced the antibiotic efficacy.
A component of our team then conducted an evaluation to discover the compounds present within the tormentil extract. Plants are known for naturally occurring compounds, akin to ellagic acid and agrimonin, which have antioxidant and anti inflammatory properties.
We tested the ellagic acid and agrimonene compounds present in our bogland tarmantal. We showed that these specific compounds can inhibit bacterial growth. This indicates that they could be chargeable for the antimicrobial activity of tormentil.
We later found that these compounds were doing this by scavenging iron – a nutrient essential for bacterial growth. It effectively starves the bacterial cells, stopping them from growing. We are actually specializing in developing a formulation to enhance this antimicrobial activity and test its potential as a therapeutic in experimental models.
Nature has all the time been a wealthy source of drugs. Many of the antibiotics we use today actually come from natural sources. For example, powerful, last-resort antibiotics Vancomycin – which is used to treat MRSA (methicillin-resistant) infections – comes from soil microbes.
with antimicrobial resistance Global growth continues.We urgently need latest methods and coverings. Plants could be an understudied source of each latest antimicrobial compounds and compounds that make existing drugs more practical.
Tormental’s story shows how nature and traditional medicine can work along with modern science to tackle today’s challenges. It also highlights that solutions could be present in unexplored places – even in a tiny yellow wildflower growing in a bogland.
