Erect cinquefoil

Potentilla erecta, commonly known as tormentil, is a plant traditionally used in European folk medicine. While its specific applications are not well-documented, it has been associated with various traditional uses, including treatment of wounds and skin conditions. Scientific evidence suggests that extracts from the rhizome inhibit the growth of carbapenem-resistant Acinetobacter baumannii by disrupting intracellular iron homeostasis and potentiate colistin activity. Additionally, ethanolic extracts of tormentil rhizome and their gut microbiota-derived metabolites exhibit antioxidant properties and show variable immunomodulatory effects on human immune cells. The review indicates that Potentilla species display a range of pharmacological activities, including multiple anti-inflammatory effects, supporting some traditional uses; however, further in vivo and clinical studies are needed to confirm these applications. No major safety concerns or recorded drug interactions have been identified for this plant.
