Support healthy urinary system function with Goldenrod liquid extract from Herb Pharm. We prepare our Goldenrod Extract from fresh (undried) flowering tops of Solidago canadensis plants which are Certified Organically Grown on our own farm or are Sustainably Wildcrafted in their natural habitat. To assure optimal extraction of Goldenrod's bioactive compounds, the uppermost tops of the plants are hand-harvested when just beginning to flower and are then taken directly to our laboratory and promptly extracted while still fresh and succulent.
