Himalayan salt is rock salt or halite from the Punjab region of Pakistan. Numerous health claims have been made concerning himalayan salt, but there
is no scientific evidence that it has better effects or healthier than common table salt and the claims are considered pseudoscience.
Although its salt is sometimes marketed as "Jurassic Sea Salt", this salt deposit comes from a seabed of the Permian and Cretaceous eras 100 to 200
million years ago. This sea became landlocked and evaporated, leaving a dense salt deposit, colored by a common pink microorganism that had lived in
it. Over the next few hundred million years, that deposit was at the border of a continental plate, and was pushed up into a mountain range in
Pakistan.
The concentration of salt near Khewra, Punjab, is said to have been discovered around 326 BC when the troops led by Alexander the Great stopped to
rest there and noticed their horses licking the salty rocks. Salt was probably mined there from that time, but the first records of mining are from
the Janjua people in the 1200s.
Himalayan salt is mostly mined at the Khewra Salt Mine in Khewra, Jhelum District, Punjab, which is situated in the foothills of the Salt Range hill
system in the Punjab province of the Pakistan Indo-Gangetic Plain.
Himalayan salt is chemically similar to table salt plus mineral impurities including chromium, iron, zinc, lead, and copper. Some salts mined in the
Himalayas are not suitable for use as food or industrial use without purification due to these impurities.
Some salt crystals from this region have an off-white to transparent color, while impurities in some veins of salt give it a pink, reddish, or
beet-red color. |
