(Bio-Nutrition) AspirEase III may be used in the management of pain, inflammation, and arthritis symptoms in horses. AspirEase III contains salicin, a highly refined botanical COX-2 inhibitor that is often referred to as "nature's aspirin." Salicin is the natural precursor to aspirin and has a similar chemical composition. Salicin does not contain the acids found in aspirin, making it less likely to cause stomach upset or thinning of the blood. Give 1 scoop once or twice daily with feed, as needed. Microencapsulated, molasses-flavored formula. Granular.
