Forgotten Medicinal Plant Shows Promise in Fighting Dangerous Superbugs

Researchers screened more than 70 Irish bogland plants for antibacterial potential.

Tormentil (Potentilla erecta) stood out by showing antimicrobial activity and blocking biofilm formation in lab tests.

The extract also helped low-dose colistin work better against bacteria, including resistant strains.

The findings suggest a traditional medicinal plant could support new treatments for drug-resistant infections.
