Calculer une dose sûre de Corn Silk
Calculateur gratuit de posologie — doses adultes et enfants selon le poids.
Corn silk contains flavonoids and saponins that increase urine output by promoting renal blood flow and gently stimulating kidney filtration. Its mucilaginous compounds, including allantoin, provide a soothing demulcent effect on the urinary tract lining, reducing inflammation and irritation. The herb also contains natural potassium, which helps maintain electrolyte balance during increased diuresis. This dual action of promoting fluid elimination while soothing urinary tissues makes corn silk effective for urinary tract infections, cystitis, and bladder irritation. Evidence level: C (preliminary pharmacological studies support traditional use).
Can I take corn silk with diuretic medications?
Corn silk should be avoided when taking potassium-sparing diuretics such as spironolactone, triamterene, or amiloride. Combining corn silk with these medications may cause excessive potassium retention, potentially leading to hyperkalemia. Corn silk may also enhance the effects of other diuretic medications, increasing the risk of dehydration and electrolyte imbalances. If you take any diuretic medication for blood pressure, heart failure, or edema, consult your healthcare provider before using corn silk. Monitor for symptoms including muscle weakness, irregular heartbeat, or excessive urination.
What is the recommended dosage for corn silk tea?
The standard adult dosage for corn silk is 4-8 grams of dried silk prepared as a tea, taken up to three times daily. To prepare, steep the dried corn silk in boiling water for 10-15 minutes, then strain before drinking. Alternatively, 5ml of corn silk tincture taken three times daily provides a convenient option. For acute urinary symptoms, the higher end of the dosage range may be appropriate. Start with a lower dose to assess tolerance, and reduce dosage if excessive urination occurs.
Is corn silk safe to take during pregnancy?
Corn silk is considered safe during pregnancy when used in recommended food-amount doses. Traditional use across cultures supports its safety profile for expectant mothers experiencing mild urinary discomfort or fluid retention. The herb's gentle, non-irritating nature makes it suitable for pregnancy-related urinary concerns. However, pregnant women should avoid excessive doses and consult a healthcare provider before using concentrated tinctures. Use the lowest effective dose for the shortest duration needed, and discontinue use if any adverse reactions occur.
Can corn silk help with urinary tract infections?
Corn silk has been used traditionally for urinary tract infections and cystitis due to its diuretic and demulcent properties. By increasing urine flow, it helps flush bacteria from the urinary tract while soothing compounds reduce bladder inflammation and irritation. Evidence level C supports this use through traditional practice and pharmacological studies, though clinical trials are limited. Corn silk works best as supportive therapy alongside conventional treatment for active infections rather than as a standalone remedy. Consult a healthcare provider if symptoms persist beyond a few days.
Does corn silk help with kidney stones?
Traditional herbal medicine uses corn silk for kidney and bladder stones. Its diuretic action increases urine volume, which may help flush small stones and prevent crystal formation, while demulcent properties soothe irritated urinary tissues during stone passage. Evidence level C indicates support from traditional use and preliminary research, though specific clinical trials for kidney stones are lacking. Corn silk may be most beneficial as preventive support alongside adequate hydration and dietary modifications. Seek medical evaluation for suspected kidney stones, as complications may require intervention.

Résumé
Corn silk (Zea mays), the styles and stigmas of maize, is a traditional medicinal herb with reported antioxidant, anti-inflammatory, and metabolic regulatory effects [PMID:40437199, PMID:38398644].
Contexte
Corn silk consists of the hair-like stigmata of female maize flowers [PMID:37361240]. It is an agricultural byproduct of Zea mays L., a global cereal crop [PMID:42227415, PMID:40461278].
Usages traditionnels
Corn silk is used as a traditional medicine in many nations, including China, the United States, Turkey, and France [PMID:37187994, PMID:22890173]. It has been traditionally used by the Chinese and Native Americans to treat various diseases, and is used in teas and supplements for urinary-related problems [PMID:22890173].
Composés actifs
Bioactive constituents include flavonoids (such as quercetin, rutin, and apigenin), polysaccharides (specifically corn silk polysaccharide or CSP), polyphenols, sterols (such as beta-sitosterol), terpenoids, saponins, phenolic acids, fatty acids, and organic acids [PMID:37361240, PMID:40437199, PMID:42227415, PMID:38398644].
Mécanisme d'action
Corn silk may exert its effects through several signaling pathways, including the down-regulation of the PI3K/AKT/NF-κB pathway to reduce inflammation and apoptosis in hyperuricemia [PMID:37294890], and the PI3K/Akt pathway for anti-cancer effects [PMID:37361240]. Other involved pathways include Nrf2 and FoxO1 [PMID:42227415]. In the liver, acidic polysaccharides (CSP-50E) may function through the caspase cascade and mitochondrial apoptosis pathway [PMID:36863670].
Preuves cliniques
Preuve ADyslipidemia/Angina Pectoris
A meta-analysis of four RCTs indicated that corn silk decoction is effective in improving the lipid profile in patients with angina pectoris [PMID:31423665].
Preuve BDiabetes/Hyperglycemia
Preliminary clinical trials show promise for anti-diabetic effects, though larger RCTs are needed [PMID:40437199].
Preuve DHyperuricemia
Corn silk flavonoids exhibited uric acid-lowering activity in vitro and in vivo by inhibiting xanthine oxidase (XOD) and promoting uric acid excretion [PMID:37294890].
Preuve DHepatoprotection
Acidic polysaccharides from corn silk (CSP-50E) showed significant hepatoprotective effects in vitro by reducing IL-6, TNF-α, AST, and ALT activity in ethanol-induced damaged liver cells [PMID:36863670].
Sécurité et effets indésirables
Corn silk is noted for having fewer adverse reactions compared to conventional anti-hyperglycemic drugs [PMID:37187994]. However, comprehensive safety and effectiveness evaluations are still being reviewed [PMID:36721262].
Synthèse des preuves
The evidence for corn silk is primarily based on preclinical in vitro/in vivo studies and reviews (Level C/D), with one systematic review/meta-analysis (Level A) supporting its use for lipid profiles in angina pectoris and preliminary clinical data (Level B) for diabetes.
