• Approved by Commission E for irrigation therapy for inflammation
of the lower genitourinary tract, urinary calculi and kidney gravel;
also as prophylaxis for urinary calculi.
• Hyperuricemic use: 30-minute infusion of one tablespoon of dried plant per cup of water; 3 cups daily.
2-3 teaspoons of dried herb in one cup of hot water, let stand for 10 min, strain, drink 3 times daily.
Decoction of herb as gargle, 3 times daily.

Tantanduk may increase the effect of diuretics and cause dehydration or negative fluid balance. Because of the diuretic effects, it may cause certain drug levels to increase in the blood; ex: lithium.
Extract study shows S virgaurea exhibited strong cytotoxic activities
on various tumor cell lines (human prostate, breast, melanoma, and small cell lung carcinoma) and showed promise as an antineoplastic
medicine with minimal toxicities.
• Anti-Inflammatory / Herbal Combinations:
Study of extracts of P tremula, Solidago virgaurea and F excelsior, individually and in 3 different combinations in the carrageenan-induced edema and adjuvant-induced arthritis of rat paw showed significant dose-dependent anti-inflammatory activity. The activity of herbal combinations was comparable to diclofenac.
• Antioxidant / Antimicrobial:
Study of various extracts to determine antioxidant activity showed the methanol extract to have the highest activity. The methanol extract also showed antimicrobial activities against S aureus, Enterobacter faecalis, E coli and Bacillus cereus.
• Osteoarthritis / Review / Phytodolor:
(1) Review of trials showed promising evidence for the effective use of some herbal preparations in the treatment of osteoarthritis. (2) Phytodolor is a combination of alcoholic extracts of Populus tremula, Fraxinus excelsior and Solidago virgaurea in 3:1:1 proportion. The active ingredients are salicin, salicyl alcohol, phenolcarbon acids, flavonoids. triterpensaponines and coumarin derivatives. Its mechanism of action is proposed to be the inhibition of arachidonic acid metabolism via COX and lipooxygenase pathways, with subsequent suppression of mediators of inflammation such as PGE2.
• Prostate Cancer:
Study tested the hypothesis that FAS (Fatty acid synthase) is strongly expressed in prostate cancer cells and that an active component of S. virgaurea specifically inhibits the FAS activity and induces apoptosis in the prostate tumor cells. A 48kD protein was identified as an active component. Results suggest a potential utility for S. virgaurea as chemopreventive and therapeutic remedy for prostatic cancer.
• Antibacterial / Antimutagenic:
Study evaluated hexane and ethanolic extracts of above ground parts of Solidago species (S. virgaurea, S. canadensis, and S. gigantea). S. virgaurea yielded thirty nine and forty nine volatile compounds respectively in EE and HE. The hexane extract showed a weak antibacterial effect. The hexane extract exhibited antimutagenic activity.
