Crystalline rock salt from the Himalayas originated from the evaporation of the primeval sea during hundreds of millions of years. The solar energy, required to achieve this was trapped in every atom of the salt crystals as so-called bio-photons. Apart from this energy every mineral of this earth is present in this crystalline salt in quantities that would correspond with the quantities of these minerals in our cell structures, if we would feed ourselves in the ideal way. These minerals are so small, that they can be taken in by our body on the cellular level.

Himalayan salt is a marketing term for Halite (commonly known as rock salt) from Pakistan, which began being sold by various companies in Europe, North America, and Australia in the early 21st century. It is mined in the Khewra Salt Mines, the second largest salt mine in the world, located in Khewra, Jhelum District, Punjab, Pakistan, about 300 km from the Himalayas, about 160 kilometres from Islamabad, and 260 kilometres from Lahore, and in the foothills of the Salt Range.
The salt sometimes comes out in a reddish or pink color, with some crystals having an off-white to transparent color. It is commonly used for cooking similar to regular table salt, brine, and bath products.
So it's no more Himalayan than I am then.
A biophoton or ultraweak photon emission, low-level biological chemiluminescence, ultraweak bioluminescence, dark luminescence and other similar terms, is a photon of light emitted from a biological system of living biological cells.
So it's not that then either.
