Himalayan salt licks are made from pure, food grade, Himalayan salt crystals and can even be powdered to use as salt in recipes if needed.
Horses require about 1-2 ounces of salt per day to help meet their requirement for sodium and chloride. This can increase to 4-6 ounces of salt per day in hot climates or under exercise where losses in sweat increase greatly. Inadequate salt in the diet can result in abnormal eating behavior such as licking or chewing objects which have salt on them or licking/eating dirt. Water intake may also decrease, increasing the risk of impaction colic. In more extreme cases, horses will stop eating and may experience muscle in-coordination.
