[Zea Mays] Cornsilk (the silky fronds wrapped around the cob) has always been the part of the plant most used medicinally, and is of particular value in treating urinary conditions. It is thought to stimulate production of bile, improving its flow from the liver through the bile ducts. Partly due to its significant potassium content, cornsilk is a useful diuretic for almost all problems of the urinary system.
It soothes and relaxes the lining of the urinary tubules and bladder, relieving irritation and improving urine flow and elimination. It is also helpful in humans for frequent urination caused by irritation of the bladder and urethral walls, and for difficulty in passing urine, for example in prostate disorders.
