We've been using MII products exclusively for almost 8 years :) And yes, everything I've ever read & experienced shows me they are very safe for folks with MCS issues (in fact, I can't imagine anything better!)
We use the full line of products for EVERYTHING! I can't say how the gel for toothbrushing will do for blueberry stains, but it whitened my teeth substantially :) (I like using gel on my toothbrush atop 5-10 drops of the Tooth & Gum liquid :)
Willowley has recently started using MII products...I bet we can get her to 'say a few words' :::grin:::
Hit it, Willowley!!!
Uny
P.S. Here's another source with great (better?) prices! http://www.missdaisyshealth.com/
It seems the original source I listed is a bit slow to respond to orders lately. I've never actually purchased anything from the site above, but the prices are certainly right.
