Bladder spasms, sometimes called "urge incontinence," are sudden contractions of the bladder that can send you running to find a restroom. The typical bladder holds up to 550 mL of urine, according to MedlinePlus, a division of the National Institutes of Health, but the urge to urinate begins when the bladder contains about 200 mL of urine and increases as more urine fills the bladder. Bladder spasms are intense contractions that trigger an immediate need to urinate, even though the bladder may not be full. Cornsilk is an herb with a long history of use in urinary tract conditions, but scientific research verifying its benefits are lacking. Consult your doctor for more information.
Cornsilk
Cornsilk, the translucent whitish-green threads that form on the top of an ear of corn contain volatile oils, flavonoids, fatty oils and alkaloids. The tannins and saponins may be responsible for the herb's effects on the bladder, according to the "PDR for Herbal Medicines." Harvested before the ear of corn is pollinated, cornsilk is available in bulk powder form, or in capsules or tincture.
Potential Benefits
The benefits of cornsilk for treating urinary disorders are anecdotal, but use of the herb for inflammation of the bladder, painful urination, bedwetting and incontinence in the elderly is a time-honored folk remedy, reports the "Gale Encyclopedia of Alternative Medicine." Although there is no specific recommendation for cornsilk in the treatment of bladder spasms, the herb may be soothing and relaxing to the bladder, which may alleviate spasms triggered by dietary irritants.
Dosage and Method
The FDA does not oversee the manufacture of cornsilk remedies or supplements, so a recommended standard dosage does not exist. However, the "Gale Encyclopedia" offers a suggested method for preparing cornsilk tea by pouring 1 cup of boiling water over 1 tsp. of the dried herb and steeping for 15 minutes before straining. Drink up to three cups of tea per day. For other forms of the herb, follow package dosage instructions, or contact a doctor for specific dosage advice.
Considerations
Cornsilk remedies are generally safe when taken according to package instructions, but herbal remedies cannot replace the need for professional medical advice. There are no known side effects or drug interactions from taking cornsilk, but that may be, in part, because studies on the herb are lacking. See your doctor for symptoms of bladder spasm and use cornsilk as part of a doctor-recommended treatment plan.
