<<If you want to know what safety studies Matrixx has conducted or are required to conduct, perhaps you should call the company.>>
Why don't you call? I'm sure they would be happy to share that with you. BTW, I have looked for ANYTHING, positive or negative about the safety issue. Zinc having GRAS status is old news. No one is saying that zinc is dangerous when taken orally. I have been refering to intranasal zinc and you know it. Stay on topic. As I said before, you would think that from the beginning, MTXX would shout their safety research from the rooftops (if they had any). If they do have it and they're not publishing it, why are they keeping it so private? There is no good reason to keep it private. You know as well as I do if they have a study that puts their product in a good light, they would make it public. It is not good business to withold good news like that. "No known side effects" is not good enough. I can't believe you would buy into the idea that they just chose not to make it public. Face facts, Dan. They WOULD publish it and you know it.
<<The zinc gluconate nasal spray tested had a lower viscosity than Zicam Cold Remedy nasal gel.>>
<<The gel is thick enough to ensure that the zinc remains in contact with the nasal mucosa long enough to be effective, but not so thick that it doesn't spread properly.>>
And whenever the zinc ions in that gel come in contact with the olfactory cells they cling longer than a low viscosity spray. The ions have additional time to damage the olfactory receptors. Your water comparison is worthless and so is your other theory about benzalkonium chloride. Just because it is zinc gluconate does not mean it protects users from the toxicity of zinc ions. It doesn't matter if it is zinc gluconate or zinc sulphate. They both contain zinc ions. 1% or 2% like Zicam Cold Remedy. Studies and research on intranasal zinc is not new. You can find it in JAMA articles from the 1930s. I've been to the library and found them. Want to see proof? This is a verbatum quote from a JAMA article that was written during the Toronto polio epidemic trials during 1937.

THE CHEMICAL PROPHYLAXIS FOR POLIOMYLELITIS: THE TECHNIC OF APPLYING ZINC SULFATE INTRANASALLY June 26, 1937 Vol 108 #26
By Max Peet M.D. Dean Echols M.D. Harry Richter M.D.
"Zinc sulfate has long been used in diseases of the eye and nose with out a single instance of serious harm resulting. With such a weak solution as 1 per cent, the strength recommended for nasal instillation and in the small quantity used, we feel certain that no serious sequelae (after-effect of injury) will result. However, it was found that when zinc sulfate was actually applied to the olfactory area, it produced a severe burning or smarting sensation with coryza (nasal mucus) and in most subjects a severe headache, which lasted for several hours. Zinc sulfate introduced into the lower portions of the nose does not produce such symptoms. It is only when it is applied to the olfactory area that this pain results."
It obviously surprised the doctors back in 1937, Dan. No need to tell you what happened to about 25% of those 5,000 plus kids. I think you read about that already. Do you still have no doubts about the safety of intranasal zinc? I have more. I'll show it to you later. |
