Horses’ legs are designed to “shunt” blood away from the lower legs. A horse’s blood vessels close off to keep blood from entering the lower legs in severe cold, thereby keeping the horse and its vital organs safe. This is one of the ways many animals thermo-regulate. However, horses, deer and many birds take it to the extreme as they are designed to endure and even flourish in cold temperatures. That’s why you see birds in winter firmly gripping a branch with their bony legs and horses standing on frozen ground for hours and not getting frostbite on their legs.
This unique physiology plays a specific role in managing blood flow. If you cool a horse’s limb, its body will naturally react by limiting incoming blood flow to the area as described above. Yet increased blood flow is essential for long-term healing. This is where Absorbine Veterinary Liniment does its best work. Applying cold reduces swelling, then applying Absorbine Veterinary Liniment helps move fresh, healing blood into the area and carries away harmful elements.
