The use of salt as a healing ingredient appears in some of the oldest medical scripts. The ancient Egyptians refer to the use of salt for the treatment of an infected chest wound. The belief was that salt would dry out and disinfect the wound. The ancient Egyptians had many salt formulations for making laxatives and anti-infection methods using salt. Salt-based remedies were also used for callous skin, epidemic diseases, to check bleeding, as an eye ointment, and to accelerate childbirth.
Both sea salt and rock salt were well known to the ancient Greeks who noted that eating salty food affected basic body functions such as digestion and excretion (urine and stools).

Salt-water was used externally against skin diseases and freckles. Hippocrates also mentions inhalation of steam from salt-water. We know today that the anti-inflammatory effects of inhaled salt provide relief from respiratory symptoms. Thus, 2000 years ago, Greek medicine had already discovered topical use of salt for skin lesions, drinking salty or mineralized waters for digestive troubles and inhaling salt for respiratory diseases!
The Greek doctor Galen from Pergamon (129–200 A.D made use of salt (sea salt, rock salt, salt foam) in recipes against many diseases: infectious wounds, skin diseases, callosities, digestive troubles. His list of salt-containing remedies also included emetics and laxatives.

A hip-bath in salt water was a superb remedy for skin diseases and itching: "This brine - he said - is better than all the health spas arising out of nature." He described the diuretic effect of salt consumption and prescribed salt preparations of different strengths that were used for instance against constipation.

Our journey through history has revealed that the antiseptic action of salt on the skin and mucous membranes has been known for a very long time. Scientific studies have now confirmed the effectiveness of salt therapy in several indications.

Medicinal use tended to emphasize the positive aspects of salt, e.g. prevention of putrefaction, reduction of tissue swelling, treatment of diarrhea.
