Free of synthetic mineral oil, petroleum jelly or any other insoluble lubricants that may interfere with healthy nutrient absorption in the gut, Hairball Relief Formula contains one ingredient:  Marshmallow Root Extract. 

Marshmallow root extract assists with passage of waste and to help maintain healthy, active microflora in the gut.  As marshmallow root extract passes through your companion’s digestive tract, it’s thick, gooey mucilage temporarily coats intestinal membranes with a slippery layer to aid in the quick elimination of ingested hair, while it also serves to feed and maintain healthy populations of resident microflora.

Directions for use:   Cats.   .5 ml 1-2 times daily. Apply directly into your cat's mouth for best absorption.
