Cornsilk tincture Corn silk is used for bladder infections, inflammation of the urinary system, inflammation of the prostate, kidney stones, and bedwetting. It is also used to treat congestive heart failure, diabetes, high blood pressure, fatigue, and high cholesterol levels. Cornsilk is also a natural source of vitamin K and potassium. Comes in a 1oz amber glass bottle. I use the folk method for making all my tinctures, which uses no measurements except sizing things up with your eyes. So I put the plant material in a jar and then fill with alcohol. For more information on herbs and to read my blog, go to http://www.theherbalcache.com/
