After using a same type of product a long time ago I was put back on this product 2 years ago. I became very ill in the 5 or 6 months after using it every day. I learned I had a bad tooth after it was out I seemed to be better yet never achived total health. Then a year and a half later I would "catch everything" as in I was sick a whole lot and had a constant leg pain. Now after this spring I stopped using it. Slow but sure my health started to return. Then a few weeks ago the fall time nose things started to kick up and I got the stuff out and started using it as I was told and wow sick again. The leg pain, joints hurting all the same things came back. I am not using it again and I will be speaking with my Dr. about this. I do not think this is a "safe" product for anyone to be putting up their nose.
