Promotes Rapid Healing and Reduces Pain & Itching! Natural to the body, collagen is a fibrous protein found in skin, muscle,and connective tissue. The collagen in EMT Gel interacts with the wound at every stage to assist in the healing process. It works with the blood to form a plug and encourage natural blood clot formation. It provides a cellular matrix to help speed new cell growth and healing, acts as a tissue adhesive,and minimizes scarring. It forms a protective barrier over the wound to prevent bacterial infection and seals off nerve endings reducing pain and itching. May also be used on burns. Spray contains Bitrex, which is very bitter, to deter biting and licking of the wound. Safe for all large and small animals.
