Corn

Corn
Corn, also known as Maize, is one of the most popular cereal grains of the world. It contains various nutrients and phytochemicals (such as carotenoids and phytosterols) that plays a very important role in managing various diseases. Apart from Corn, Corn silk (which are long strands attached to an ear of corn) is also used for medicinal purposes.
Corn helps in managing weight due to the presence of dietary fibres. It maintains the levels of blood sugar by enhancing insulin secretion due to its blood sugar-lowering property.It helps in reducing pain and inflammation related to rheumatoid arthritis due to its antioxidant and anti-inflammatory properties.
Corn silk tea prepared by boiling corn silk in water is useful for bladder problems. Drinking Cornsilk tea increases the production of urine and helps in easy removal of kidney stones due to its diuretic activity. This is also useful for managing diabetes and blood pressure related problems.
It is advisable to consult a physician before taking Cornsilk tea in diabetic patients as it might cause too much lowering of blood sugar due to its blood sugar lowering property. It might also cause allergies like skin rash and irritation among hypersensitive individuals[2][11][12].
