Saw Palmetto, capsaicin, resiniferatoxin, cornsilk and horsetail are herbal remedies for stress urinary incontinence, a form of overactive bladder characterized by leakage during physical activities, according to WebMD and the Brigham and Women's Hospital. Sufferers often seek out natural remedies after conventional remedies fail or to avoid negative side effects.
Saw palmetto comes from the berries of the dwarf palm tree and contains compounds that complement the nerves in the urinary tract, explains WebMD. Resiniferatoxin and capsaicin block nerves in the bladder that stimulate the urge to urinate. Cornsilk are the fine threads present in corn shucks used for treating both urinary tract infections and incontinence. Horsetail contains antioxidants that reverse the effects of aging that cause the bladder to become fibrous. There is very little evidence that these remedies work, however.
