The intention behind Cornsilk KB is to support to the urinary system. 

At Cheryl’s Herbs, our liquid extract combination products each contain multiple herbs and are sold in one-ounce, two-ounce, and four-ounce dropper bottles.  These products are for internal use.   

The eight herbs in the Cornsilk KB Liquid Extract Combination are:

Cornsilk - is used to support the urinary system when a bladder infection is present.  It has, as a demulcent, a soothing effect upon the mucus membranes of the urinary tract.

Hydrangea Root - is well known for its ability to support us when gravel and stones are present in the urinary system, assisting in their dissolution and passage.

Horsetail Herb - is a nourishing diuretic that supports the mucus membranes of the urinary tract helping to ease burning pain.

Cleavers Herb - can assist in remedying bladder infections and stones and can assist in promoting urination.

Uva Ursi Leaf - is an astringent and antiseptic so is helpful with bladder infections, bladder discharges, and when there is highly acidic urine.

Buchu Leaf - when there is highly acidic urine and a frequent desire to urinate with little or no relief, this herb is suggested.

Juniper Berry - purported to be of benefit where there is renal congestion, swelling, and back ache.

Marshmallow Root - a demulcent herb that eases the passage of stones, it also supports diuresis.

Overall, this product, as with any other of our liquid extract combinations, is a synergy offering more to us than any one of the individual herbs in it can offer, thereby supplying significant support to the urinary tract when there is infection.  It is soothing to the mucus membranes when urine is highly acidic, helping to relieve burning pain; it helps promote urination; it has antiseptic action; and it can be used to dissolve stones and soothe their passage.

This combination of herbs helps support the urinary system.

Use 5-15 drops, 1-2 dropperfuls, or as much as a teaspoon at a time. Dose frequency could be 1-3 times or several times a day as desired. Generally best to use large, frequent doses in acute situations. When more comfort is achieved, or the situation is less severe, doses can be smaller and less frequent. Dose recommendations are for adults. For a child, adjust the dose according to weight. For example, if a child weighs approximately half what an adult weighs, give half of any of the above dose suggestions.

Do not use herbal products to replace necessary care by a qualified physician.
