Underwood Horse Medicine is a liquid topical spray packaged in a 16 oz bottle, intended for external use on cuts, punctures, rips and tears of the flesh. The spray is applied directly to the affected area and is meant to be used alongside a light dusting of baking powder, which forms a protective layer over the wound as it dries. The product is applied without first washing or flushing the wound, since rinsing can remove the medicine and introduce excess moisture to the area. Owners typically reapply the spray multiple times a day, shaking the bottle well before each use to maintain an even mixture. The spray format allows coverage of the treated area without extensive direct handling of the wound. Each bottle is intended for use as part of an ongoing wound care routine rather than a single application. It is commonly kept in barns, horse trailers, and farm first aid kits for ready access when an injury occurs.
