• Urinary calculi: 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.
• Diuretic: Popular use as diuretic and flushing property prior to drug testing.
• Gout / Hyperuricemia: 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.
(1:5) in 45% ethanol (90 proof lambanog will do); 2 - 4 cc, 2 to 3 times daily.
Study evaluated the cytotoxic activity of S. virgaurea on rat prostate cell line (AT6.1) and SCID mouse model. TheG-100 fraction was administered intraperitoneally and subcutaneously. Tumor growth was significantly suppressed without apparent side effects. Results suggest a potential antineoplastic medicine with minimal toxicities. (5)
• Anti-Inflammatory / Herbal Combinations:
Study of extracts of P tremula, Solidago virgaurea and F excelsior (components of Phytodolor N), 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. (8)
• 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:
Review of trials showed promising evidence for the effective use of some herbal preparations in the treatment of osteoarthritis.
• Phytodolor / Anti-Inflammatory: 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. (8)
• 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. (14)
• 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. (15)
Plants species traditionally used for relief of pain, including Solidago virgaurea, were studied for biologic activity in three in vitro receptor radioligand binding assays. Results showed strong indication for biologic activity in some of the plants in the three in vitro receptor binding assays, and particular plants exhibited selective action to a single receptor. (16)
• Antioxidant / Antimicrobial:
Study evaluated methanol and hot water extracts for antimicrobial and antioxidant activities. The methanol extract showed the highest DPPH-radical scavenging activity. The methanol extract also showed antimicrobial activities against Staphylococcus aureus, Enterobacter faecalis, E. coli and Bacillus cereus. (17)
• Diuretic Effect / Leiocrposide:
Leiocarposide has been isolated from Solidago virgaurea. The compound was shown to exhibited diuretic activity in rats, only 75% lower than furosemide. (18)
• Combined Herbal Supplement in Canine Osteoarthritis: Closed-label, single-arm study evaluated the pain relieving effect of an herbal supplement—extracts combination of juniper goldenrod, dandelion, meadowsweet, willow and cranberry—in dogs suffering from chronic osteoarthritis. Results showed the herbal supplement to substantially reduce pain and lameness while also substantially improving the quality of various life activities. (19)
• Diuretic / Drug Interaction:
Tantanduk may increase the effect of diuretics and cause dehydration or negative fluid balance, and cause dizziness and lower the blood pressure. Examples of diuretics are chlorothiazie, chlorthalidone, furosemide, hydrochlorothiazie, hydrodiuril, etc. Because of the diuretic effects, it may cause certain drug levels to increase in the blood; ex: lithium. (21)
• Commission E: Commission E approved goldenrod herb as irrigation therapy for inflammatory diseases of the lower urinary tract, urinary calculi, and kidney gravel, and as prophylaxis for urinary calculi and kidney gravel. (Contraindication: No irrigation therapy in cases of edema due to impaired heart and kidney functions.) (23)
• Treatment of Urinary Tract Infections: Review examines clinical data on the use of Solidago virgaurea for urinary tract infections. Extracts of goldenrod ca be used in the complex therapy of urinary tract diseases to increase effectiveness of therapy, accelerate recovery and reduce relapses. (24)
• Herbal plant combination / Anti-Inflammatory / Antirheumatic: PD (Phytodolor N), a combination of three herbal plants i.e., Populus tremula, Solidago virgaurea, and Fraxinus excelsior, has shown anti-inflammatory and antirheumatic properties on in vitro and in vivo studies, comparable to NSAIDS, with little or no side effects. (25)
• Inhibition of Candida Yeast-Hyphal Transition and Biofilm Formation: Xerostomia is a decrease in secretion of saliva, which can cause imbalance of the oral microflora to produce a beneficial environment for Candida albicans. Study evaluated a water extract of S. virgaurea for potential use as a dry-mouth daily-care mouthwash. Results showed biofilm formation and pre-formed biofilms were both strongly inhibited. Results suggest S. virgaurea extract was efficient against two key virulence factors of C. albicans i.e., yeast-hyphal transition phase and biofilm formation. (26)
