Herbs & Supplements:
Goldenrod
Solidago spp.
Principal Proposed Uses
•
Mild Bladder Infections, Bladder/Kidney Stones
Goldenrod is often falsely accused of being an intensely allergenic plant,
because of its unfortunate tendency to bloom brightly at the same time and often
in locations quite near to the truly allergenic ragweed. However, actual
allergic reactions to this gorgeous plant are unusual.
There are numerous species of goldenrod (27 have been collected in Indiana
alone) but all seem to possess similar medicinal properties, and various species
are used interchangeably in Europe.1
What Is Goldenrod Used for Today?
In Europe, goldenrod is used as a supportive treatment for bladder infections, irritation of the urinary tract, and bladder/kidney stones. Goldenrod increases the flow of urine, helping to wash out bacteria and kidney stones, and may also directly soothe inflamed tissues and calm muscle spasms in the urinary tract.2 It isn't used as a cure in itself, but rather as a support to other, more definitive treatments such as antibiotics.
We don't really know how well the herb works. Several studies have found that goldenrod increases urine flow,3 but there is no direct evidence that the herb is effective in resolving bladder infections or bladder/kidney stones. Its active ingredients are not known.
Warning: Since urinary conditions are potentially serious, seek a doctor's supervision.
Dosage
A typical dosage is 3 to 4 g of dried herb 2 to 3 times daily. Make sure to
drink plenty of water while taking goldenrod, to help it do its job.
Safety Issues
The safety of goldenrod hasn't been fully evaluated. However, no significant reactions or side effects have been reported.4 Safety in young children, pregnant and nursing women, or those with severe liver or kidney disease has not been established. Individuals taking the medication lithium should use herbal diuretics such as goldenrod only under the supervision of a physician, as dehydration can be dangerous with this medication.5
Interactions You Should Know About
If you are taking lithium, do not use goldenrod except under the supervision of a physician.
