Goldenrod for Bladder Health: Evidence, Interactions and Cautions
Goldenrod is an ingredient used in bladder supplements marketed to women. Below is what it has actually been studied for, how strong that evidence is, the drug interactions and cautions on record, and the primary source our grade rests on — all drawn from the HerWellReport ingredient dataset.

What the evidence says about Goldenrod
The EMA granted goldenrod traditional-use registration only. Its assessment report found five human studies, some very large, reporting improvement rates as high as 79% in 1,487 patients and 96% in 512 patients, but every one was open-label and uncontrolled. The assessors concluded that the quality of the available studies cannot be evaluated, citing missing sample-size calculations, incomplete patient characteristics and no dropout data. Impressive percentages from studies with no comparison group say almost nothing about whether the herb did anything.
The grade "traditional" means: traditional — A long history of use but little or no human trial evidence for this outcome. Grades are explained in full on our methodology page.

Goldenrod drug interactions
No documented drug interactions in the sources we checked. That is not the same as proof of safety alongside your medication — it usually means the question has not been studied. Ask a pharmacist before combining it with prescription drugs.
