Like other salines, in febrile and inflammatory diseases, whether in horses or cattle, it is believed to lower pulse and temperature, clean the tongue, improve appetite, gently stimulate the bowels and render the evacuations more natural and less coated with mucus. It is frequently prescribed with good results in horses suffering from catarrhal conditions of the bowels. In epizootic catarrh, purpura, it is very beneficial prescribed with iron salts, as it increases the coagulability of the blood. It is also prescribed with other salines, bitter tonics or stimulants.
