Golden rods Latin name is: Solidago virgaurea Another species Solidago canadensis can also be found here in North America.
Solidago offers its medicine in its dried above ground parts collected during flowering. It is a strong diuretic and is used to treat kidney and bladder infections. A tea can be made using 2-3 grams of the dried herb, steeped in hot water. For its diuretic properties, one can drink it 3-5 times a day. Goldenrod has also been used in cough medicines and antirheumatic preparations.
Its active ingredients include a mixture of flavonoids, phenolic glycosides, a volatile oil (with mostly monoterpenes), organic acids and polysaccharides.
Suzanne Catty has written about its properties as a hydrosol. She recommends it for its strong diuretic properties and says taken internally it may aid the treatment and prevention of kidney stones. Topically, it can be used as a compress for fluid retention and uric acid in the joints and tissues. The hydrosol of goldenrod is also a strong anti-inflammatory and moderate antispasmodic for sore muscles, stiff neck, tendonitis, and repetitive strain injuries. On an energetic note: she comments that goldenrod carries the intense vibrations of heat and the sun, opens the solar plexus and diaphram, bringing a state of calm. (Hydrosols: The next aromatherapy).
According to Catty, the internal use of the hydrosol should be avoided by those with extremely low blood pressure.
