Introduction to Goldenrod Extract
Solidago Decurrens Extract is derived from the whole herb of Solidago decurrens Lour., a plant widely used in traditional Chinese medicine for centuries to promote hemostasis, reduce inflammation, and treat carbuncles, snakebites, and skin boils.
The extract is rich in bioactive compounds such as flavonoids (quercetin, kaempferol), saponins, leiocarposide, phenolic acids, tannins, and volatile oils. Leiocarposide is a key marker with analgesic, anti-inflammatory, and spasmolytic effects. Modern studies confirm its diuretic, anti-inflammatory, antibacterial, antihypertensive, and hemostatic activities. It helps relieve urinary tract inflammation, supports kidney health, and aids in preventing kidney stones.
In Europe, goldenrod species have a long history for urinary tract health. The name "Solidago" means "to make whole," reflecting its healing reputation.
