The story of Himalayan salt dates back over 500 million years, in the formative Precambrian era. The gradual evaporation of water from the inland sea left behind expansive mineral salt deposits as its residue. The seabed was led to being hermetically sealed, further with the shifting of continents, the rocks neighboring the seabed were pushed upwards inaugurating the formation of mountain ranges where these Salt Mines are now located and is called Khewra Salt Mine. Khewra Salt Mine is the second largest Salt Mine in the world and is in a city called Khewra in Pakistan, Asia.

The story of how the salt deposits at Khewra were discovered is quite intriguing. In 326 BC Alexander the Great and his entourage were passing through a South Asia region (Pakistan) and when they reached an area now called Khewra the horses began to lick the stones on the ground. This was noticed by the soldiers of Alexander the Great and when the soldiers inspected the stones, they found them to be quite salty and this is how the salt reserves at Khewra were discovered. But it was during the Mughal era that the salt started to be traded in markets and then the mine was taken over by a Sikh Commander – Hari Singh Nalwa and the Raja of Jammu – Gulab Singh. In 1872, under the British Rule the mine was significantly improved to make the process of mining the salt efficient and safe for the miners.
