I'm not familiar with it, but a couple years ago I received a small Himalayan Salt package that said "Made in the USA" on the back.
I still wonder (a) where this product actually came from and (b) why they call it Himalayan if it is made in the USA? What is the characteristic that makes it Himalayan if it doesn't come from, y'know, the Himalayas?
I did *not* notice this product regularly used or sold while I was in Nepal. At least not packaged and marketed to Westerners the way it is elsewhere.
