The history of Salt Therapy (Halotherapy/Speleotherapy) can be tracked from ancient times. Historical records contain information on the treatment in salt mines since 500 BC. Salt caves attracted the attention of clerics in ancient Greece.
The ancient Indian epic poem “Ramayana” written around 200 AD, tells how the soldiers, exhausted by chasing the kidnappers of children, took refuge in a salt cavern. Breathing the air of the salt cave, the warriors surprisingly quickly regained their strength and overtook the enemy.
In the mid 18th century a Polish health official Felix Botchkowski noticed that the workers of salt mines did not get ill with lung diseases. He wrote a book about the effects of salt dust in 1843. His successor M. Poljakowski founded a Salt Spa in Velicko near Krakow which is still in operation today. During the Second World War salt mines were often used as bomb shelters. After spending time in the mines, many people, despite harsh labor conditions and poor nutrition, even those who suffered from asthma and other lung diseases felt that their health had improved.
