Biological Activities
Compounds
Conditions
Geum rivale exhibits a high capacity for treating elastase inhibiting activity due to its significant tannin content. As a member of the Rosoideae subfamily, this specific species demonstrates much higher activity levels compared to others in the Rosaceae family. This inhibitory effect is closely linked to the plant's rich concentration of tannins. While other subfamilies like Spiraeoideae are less active, Geum rivale remains a potent example of this biological function. Consequently, its chemical composition makes it a notable subject for studying elastase inhibition.
Preparations
Geum rivale is prepared as a water extract to investigate its potential medicinal properties. In a study evaluating Swedish medicinal plants, this specific plant was among fifty-nine water extracts tested for anti-inflammatory activity. The research focused on the plant's ability to inhibit platelet activating factor (PAF)-induced exocytosis in vitro. Among the various samples tested, the extract from Geum rivale was identified as one of the most potent inhibitors in the PAF-test. This preparation method allowed researchers to assess the efficacy of the plant in relation to its traditional use in treating inflammatory diseases.
