This topical liquid comes packaged in a 4 oz bottle fitted with a built-in dauber applicator, so it can be dabbed directly onto an affected area without a separate cotton ball or brush. The formula combines sodium propionate, gentian violet and acriflavine in a base of water, urea, glycerine and isopropyl alcohol, and is intended for use on dogs and horses. It is designed for surface wounds, cuts, galls, chafes, abrasions, hoof and pad sores, and itchy fungal skin conditions. Before application, the affected area should be cleaned and dried, and the liquid is then applied with the attached dauber morning and night or as needed. The blue-purple tint left behind marks the treated area and can stain skin, hair and fabric. It is intended for topical use only and is not formulated for cats or for horses raised for food.
