Cornsilk

Cornsilk (Stigma maydis) is derived from the yellow, threadlike stigmas of the female flower of maize. It has a long history of use as a therapeutic remedy for a variety of conditions and is valued as a natural, plant-based alternative. Traditionally, it has been used in herbal medicine across many regions of the world, including China, Turkey, and France.

Cornsilk has also been used in the United States by Native American tribes, including the Cherokee, Iroquois, and Hopi. It was a common herbal remedy for urinary tract disorders, bedwetting, and inflammation of the kidneys or bladder. It was usually prepared as a decoction or infusion and drunk several times a day until symptoms resolved.

In Traditional Chinese Medicine, cornsilk was used to promote urination, reduce edema, clear heat, and soothe liver fire. It was sometimes recommended in cases of jaundice, gallstones, and hypertension.

During 19th- and early 20th-century Western herbalism, cornsilk was highly regarded as a mucilaginous urinary demulcent. It was often featured in herbal pharmacopeias for conditions such as irritable bladder, urethritis, and inflammation from infection or urinary stones. It was commonly used for both acute and chronic genitourinary conditions and recognized for being non-irritating and restorative.

Cornsilk is rich in flavonoids (like maysin), phytosterols, allantoin, saponins, volatile oils, and potassium salts, which contribute to its anti-inflammatory, demulcent, and mild antimicrobial effects.
