Anti-inflammatory, spasmolytic and diuretic effects of a commercially available Solidago gigantea Herb. extract.

The evaluation of a commercially available Solidago gigantea Herb. extract (Urol mono) revealed pronounced anti-inflammatory properties in the rat with respect to a reduction of the carrageenin-induced rat paw oedema. A direct comparison with diclofenac-Na (3 mg/kg b.w. p.o.) revealed that a high dose of Solidago gigantea Herb. extract possesses the same anti-inflammatory efficacy as diclofenac-Na. In addition, the Solidago gigantea Herb. extract exhibited moderate spasmolytic and diuretic properties.
