iO Paraffin Oil is a mineral oil product most commonly used in horses to treat digestive problems. As paraffin oil is not absorbed by animal cells or tissue, it acts as a lubricant, allowing for more easily excreted manure and sand from the stomach. iO Paraffin is used to treat sand colic, but also bowel obstructions (potentially caused by worms for example). iO Paraffin can also be used as a laxative in other species such as dogs and cats, and is also used a bloat treatment and prevention in cattle. Also as a bloat remedy for cattle.
