SodiPatur'ail is a garlic lick that helps protect livestock. After ingesting it, the garlic releases volatile sulphur compounds that act as a scent barrier to deter a wide range of insects (flies and ticks, etc.).
Garlic is effective on parasites in general (such as roundworms or lungworms) as it prevents the eggs from hatching into larvae for most parasite infestations. It also provides an additional, important source of phosphorus and calcium.
