Not the first time this has happened. Zicam was marketed as homeopathy, but recalled because it had real active ingredients in it. (slightly diluted zinc acetate and zinc gluconate) They caused some people to lose their sense of smell.
Yes, I actually did read it, but I seemed to have a brain fart and didn't actually notice it mentioned Zicam. Or I most likely just didn't retain the information.
