works for me but
Posted by Reviewer1162318 on Jan 24, 2015
I've used this product whenever my "cesspool' office is full of dedicated people with the flu and it seems to help (i.e. no transition to me). I am still cautious as studies say it is non pure forms taken nasally that can color the tissues and turn you silver although I still wonder how they missed it occurring. The shake and froth test appears negative with this product (frothing & low subsiding of froth= not pure).
