I called the company that I buy Himalayan salt from because I was concerned about what was posted here regarding it being bogus and a scam. (There was a bogus article posted on some website... the Webmaster has been contacted about the total inaccuracy of the article)
It is NOT bogus, it is not a scam... there are many ancient salt mines in Pakistan in the mountains.
Yes, flouride does exist in salt. It also exists in our body. It is a naturally occurring mineral and it exists in small amounts in salt and in our bodies as a harmless substance.
