Salt

Salt is a mineral composed primarily of sodium chloride that is essential for animal life, but can be toxic to many land plants. Salting is an important method of food preservation.

Salt is used in an alchemical medicine, along with Vinegar, Urine, Sal Ammoniac and a particular Sulphur Vive. Salt has more medicinal applications: the treatment to Scalerow includes rubbing the affected area with a solution of salt water, and other ingredients.

Salt is an ingredient used in the Shimmering Silver Salt Drops sold in Weasleys' Wizard Wheezes.

The saltiness of water is possibly an indicator of the agressivity of the Merpeople living within. Also, there is debate among Herbologists as to the duration of the effects of Gillyweed on freshwater versus saltwater.
