Goldenrod
AsteraceaeSolidago virgaurea L.
Also known as: European Goldenrod, Woundwort, Aaron's Rod
clinical_notes Clinical Summary
Goldenrod (Solidago virgaurea) is a perennial European herb recognized by the EMA as a traditional herbal medicine for urinary tract irrigation therapy.
Its primary actions — diuretic, anti-inflammatory, antispasmodic, and antimicrobial — are attributed to flavonoids (quercetin, rutin), saponins (virgaureasaponins, leiocarposide), and phenolic acids.
Large observational clinical studies demonstrate good tolerability with side effects occurring in less than 0.3% of users, primarily mild GI complaints.
European urologists use goldenrod extracts as adjunctive therapy for urinary tract infections, urolithiasis, and overactive bladder, with effectiveness ratings of 90-100% in open non-randomized studies.
Contraindicated in Asteraceae allergy and conditions requiring fluid restriction.
Well-established in the German pharmacopoeia (DAB) and endorsed by ESCOP and EMA.
Pregnancy Safety
No human clinical studies in pregnancy. Animal studies did not reveal teratogenic or embryotoxic effects. EMA Community Herbal Monograph advises avoiding use in pregnancy as a precautionary measure due to absence of adequate data. Traditional use does not identify pregnancy as an indication.
Lactation Safety
No data on transfer into breast milk. Avoid use during breastfeeding as a precautionary measure per EMA guidance.

Traditional Uses Across Healing Systems
While many herbs lack controlled clinical trials, centuries of traditional practice across cultures provide valuable insight into their therapeutic applications.
Irrigation therapy for the urinary tract — used to increase urine flow to treat and prevent urinary tract inflammation, cystitis, urolithiasis, and renal gravel. Also used as anti-inflammatory for arthritis and rheumatism, and as wound-healing and antiseptic agent.
German Commission E approved goldenrod for irrigation therapy of the urinary tract. EMA established traditional use for urinary tract complaints in 2008. A monograph was introduced in the German Pharmacopoeia (DAB) in 2002.
Native American peoples used related Solidago species for wound healing, sore throat gargles, fever reduction, and urinary conditions. Germanic tribes used S. virgaurea for urinary retention, kidney stones, and hemorrhoids.
The genus name Solidago derives from Latin 'solida' (whole) and 'ago' (to make), reflecting its historical use as a wound-healing herb
Used in Russian folk medicine as hemostatic and astringent, and as a remedy for respiratory diseases including tonsillitis, laryngitis, and acute respiratory infections. Also used for gallstone conditions.
Known in Russian as zolotarnik (goldsmith plant); used in decoctions for respiratory and urinary conditions

shield Safety
Contraindications — Evidence Basis
Known allergy to Asteraceae/Compositae family plants (ragweed, chrysanthemums, marigolds, daisies)
Cross-sensitization reactions are well-documented within the Asteraceae family. Contact dermatitis from Solidago virgaurea cross-sensitizing with other Compositae species has been reported. Clinically relevant cross-reactivity with latex allergy (Hevea brasiliensis) has also been identified.
Conditions requiring fluid restriction (severe cardiac or renal insufficiency with edema)
Due to significant diuretic activity, goldenrod is contraindicated where fluid mobilization could worsen the condition, such as decompensated heart failure or severe renal insufficiency with oliguric edema. Avoid in these clinical scenarios per EMA Community Herbal Monograph.
Diuretic medications (thiazides, loop diuretics, potassium-sparing diuretics)
Additive diuretic effect; may enhance potassium loss with thiazides and loop diuretics. Monitor electrolytes and blood pressure if combining. Minor interaction classified by Medscape drug interaction database.
Toxicity
No established toxic dose. Side effects in large observational studies occurred at a frequency of less than 0.3% and were mild GI complaints and allergic reactions.
Rare: mild gastrointestinal complaints (nausea, diarrhea), allergic skin reactions. No serious adverse events documented.
Discontinue if GI intolerance or allergic reaction occurs. Treat allergic reactions symptomatically.
Adverse Effects
CYP Metabolism
No clinically significant CYP450 interactions have been documented for Solidago virgaurea. Flavonoid constituents (quercetin, kaempferol) have in vitro CYP inhibitory potential at high concentrations, but clinical relevance at therapeutic doses is considered low.
swap_horiz Interactions
Lithium
Class: Mood stabilizer
Goldenrod acts as an aquaretic/diuretic (leiocarposide and flavonoid glycosides increase urine flow in animal studies). Diuresis alters renal sodium handling, potentially reducing lithium clearance and raising serum lithium levels into the toxic range (>1.5 mEq/L).
Avoid goldenrod in patients on lithium. If brief exposure occurs, obtain lithium level within 48-72 hours and monitor for toxicity signs (tremor, ataxia, nausea, confusion). Maintain adequate hydration.
Furosemide
Class: Loop diuretic
Goldenrod's aquaretic action (primarily via leiocarposide and flavonoids) adds to loop diuretic-induced diuresis. Combined use can cause dehydration, hyponatremia, hypokalemia, and orthostatic hypotension, particularly in elderly or heart failure patients.
Monitor serum electrolytes (Na⁺, K⁺), BUN/creatinine, and volume status. Anticipate need for electrolyte supplementation. Patients should be counseled about symptoms of dehydration and orthostatic dizziness.
Hydrochlorothiazide
Class: Thiazide diuretic
Additive diuretic/aquaretic effect with thiazide. Risk of hyponatremia is particularly elevated in the elderly on thiazides, and goldenrod may exacerbate this complication.
Monitor serum sodium weekly for the first month of combination, then monthly. Counsel on fluid intake (avoid over- or under-hydration). Reduce dose of either agent if hyponatremia or symptoms develop.
Spironolactone
Class: Potassium-sparing diuretic
Pharmacodynamic additive diuresis. Although goldenrod has not been shown to cause hyperkalemia, combined use with potassium-sparing diuretics can exaggerate potassium retention, especially in patients with renal impairment.
Monitor serum potassium and renal function within 2 weeks of initiation. Avoid additional potassium supplementation. Discontinue goldenrod if K⁺ > 5.5 mEq/L.
Nonsteroidal anti-inflammatory drugs (NSAIDs)
Class: NSAID (e.g., ibuprofen, naproxen)
NSAIDs can reduce renal prostaglandin synthesis, decreasing glomerular filtration, which could impair goldenrod's desired aquaretic effect and paradoxically exacerbate fluid retention. NSAIDs can also precipitate acute kidney injury in volume-depleted patients receiving diuretics or aquaretics.
Use NSAIDs cautiously with goldenrod, particularly in the elderly or patients with renal disease. Monitor renal function if combined beyond 1 week. Prefer acetaminophen for analgesia when goldenrod is used for UTI.
hub Combinations
Synergistic pairings can enhance therapeutic outcomes, while knowing suitable substitutes helps when specific herbs are unavailable or contraindicated.
Synergistic Combinations
4Dandelion
Traditional UseBoth goldenrod and dandelion are potassium-sparing diuretics that complement each other for urinary tract and kidney support. Dandelion provides additional hepatic and lymphatic support. The combination is used in detoxification and urinary flushing protocols in naturopathic medicine.
Traditional pairing widely used in Western herbal medicine; individual diuretic actions have human study support for both herbs.
Marshmallow Root
Traditional UseMarshmallow Root (Althaea officinalis) mucilaginous polysaccharides soothe and coat inflamed urinary tract mucosa, while goldenrod provides diuretic flushing and anti-inflammatory action. The combination addresses both irritation and infection in a complementary manner.
Mechanistically synergistic; combined use supported by phytotherapy guidelines for UTI management alongside adequate hydration.
Stinging Nettle
Limited EvidenceStinging nettle and goldenrod are commonly combined for benign prostatic hyperplasia (BPH) and urinary symptoms in men. Goldenrod provides diuretic and antispasmodic effects on the lower urinary tract while nettle root inhibits sex hormone-binding globulin and reduces prostate cell proliferation.
Both herbs individually studied for urinary conditions; combination marketed for BPH in European countries with traditional use basis.
Uva Ursi
Moderate EvidenceClassic European phytotherapy combination for urinary tract infections. Uva ursi provides arbutin (converted to urinary antiseptic hydroquinone in alkaline urine) while goldenrod provides diuretic flushing action, anti-inflammatory, and antispasmodic effects. Complementary mechanisms address both infection and symptoms.
Both herbs have individual EMA monographs for UTI; the combination is widely recommended in European phytotherapy practice.
science Studies
Is it Worth Combining Solidago virgaurea Extract and Antibiotics against Uropathogenic Escherichia coli rods? An In Vitro Model Study
In VitroThis in vitro study evaluated the antibacterial properties of Solidago virgaurea extract against uropathogenic Escherichia coli (UPEC), the most common urinary tract infection pathogen, and investigated its interactions with standard UTI antibiotics ciprofloxacin and amikacin. The extract significantly inhibited survival of planktonic UPEC and reduced 24-hour biofilm formation. However, combining the extract with ciprofloxacin or amikacin produced antagonistic effects, weakening antibiotic activity and shortening post-antibiotic effects. These findings support goldenrod as a stand-alone antimicrobial aid in UTI prophylaxis but indicate important cautions about concurrent use with these specific antibiotics.
Solidago virgaurea L.: A Review of Its Ethnomedicinal Uses, Phytochemistry, and Pharmacological Activities
Systematic ReviewThis comprehensive ethnomedicinal and pharmacological review systematically documented the traditional uses, phytochemistry, and preclinical activities of Solidago virgaurea (European goldenrod). The aerial parts have a long-established tradition of use for urinary tract conditions, kidney stones, rheumatism, and inflammatory conditions across European folk medicine. Key bioactive constituents include flavonoids (quercetin, kaempferol derivatives), saponins (virgaureasaponins), and phenolic acids with confirmed antioxidant, anti-inflammatory, diuretic, analgesic, antispasmodic, antibacterial, and antifungal properties. The review highlights that the available evidence is predominantly non-clinical, with a recognized need for rigorous clinical trials to validate the well-established traditional applications in urinary tract and inflammatory conditions.
