Nigari vs Ancient Mineral Purity
Last night, I tried 1/2 Epsom Salt
and 2oz Mg oil in a bath. It didn't sting my skin and I was so relaxed that I actually felt asleep in the tub! This stuff is gold! Although, I still found the filmy residue very hard to get rid of. I had to scrub it off with Sea Salt
. I'll probably continue this hybrid mixture in the bath until I exhaust all my old stash of epsom salt.
I was reading one of the old threads , and came across this article detailing the differences % Mg Sulfate & Mg Chloride here..
The same site also offers some insights on the purity of different types of Mg oil...
as well as dosage...
I still have some concern regarding the skin irritation. I got the impression from the purity article that the oil shouldn't sting the skin as long as it's free of contaminates. Or, maybe it's simply an indication of the high level of concentration which in turn causes the stinging. Needless to say, although very pure, Ancient Mineral is still *NOT* 100% heavy metal free.
On the other hand, Nigari imported by Natural Import Company (http://www.naturalimport.com/shop_for_nigari?b=1)
is completely free of PCBs and heavy metals due to the ion dialysis filtration method employed in the process of making their Nigari. The article can be found at...
Some users  swears that Nigari does the same thing as Ancient Minerals at a much lower cost. It would be interesting to see whether Nigari stings the skin or not.
