McTarnahan's Poultice McTarnahan's is applied wet and, as it dries, it draws out swelling and heat from the tendons. If properly applied, tendons will be tight vertically as well as horizontally so the spaces between them will be clearly defined. Increasingly, menthol and oils of peppermint or eucalyptus are added into the poultice for additional soothing effects. Another use for poultice is to pack hooves to draw out an abscess, although there are other poultice-like products that are more specifically intended for the purpose.
