When shucking corn this summer, save your corn silk, as it is valuable medicine. It is one of my favorite allies for the urinary tract with its soothing, cooling, diuretic and anti-inflammatory properties. I use corn silk, in tea form, with uva-ursi and marshmallow, along with cranberry juice, to help urinary tract infections || -Only use the silk from organically grown corn.Chestnut School of Herbal Medicine.
