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 herb 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

In Germany, goldenrod is used as a supportive treatment for bladder infections, irritation of the urinary tract, and bladder/kidney stones. Goldenrod is said to wash out bacteria andkidney stonesby increasing the flow of urine, and also, soothe inflamed tissues and calm muscle spasms in the urinary tract.2 It isn't used as a cure in itself, but rather as an adjunct to other, more definitive treatments such as (in the case of bladder infections) antibiotics.

However, we don't know whether goldenrod actually helps. Several studies have found that goldenrod does in fact increase urine flow,3 but there is no direct evidence that this in turn leads to any other medical benefits.

Warning: Urinary conditions such as kidney stones are potentially serious. For this reason, medical advice is recommended.
