Himalayan salt is chemically similar to table salt. Some salts mined in the Himalayas are not suitable for use as food or industrial use without purification due to 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.
Himalayan salt is used to flavor food. Himalayan salt is also used to make “salt lamps”, wherein light bulbs are placed within hollowed blocks of Himalayan salt, that give off a pinkish hue.
Himalayan salt is also used in spas, where it is used to line the walls of the chamber. There is no scientific evidence that such spa treatments have any health benefit.
