European Ash (Fraxinus excelsior) bark and leaves contain active coumarins (like fraxin), secoiridoids, and flavonoids. In traditional European medicine, ash preparations serve as an effective anti-inflammatory and anti-rheumatic agent. Fraxin stimulates the excretion of uric acid through the kidneys, making it highly beneficial for gout, while its secoiridoids act as mild diuretics and inhibit inflammatory pathways in arthritic joints.
