What is zincum aceticum and does it work?

Some samples were mailed to our office of Zinx Zincum aceticum. I had never heard of it before, so here is my research into this product. Zinx is just a trade name for a group of products made by the manufacturer Auriga Laboratories. The purported actual active ingredient is zincum aceticum. I could not find any documented information on the Internet or PubMed database. A very plausible explanation is on WikiAnswers. In short, this is a product of homeopathy and sham marketing with the production of a name. This comes from adding -um to the compound zinc acetate. The name Zinx plays off the widely accepted fact in the lay literature that zinc can prevent colds. This is never been proven in controlled studies. This is why virtually all physicians do not widely recommend taking zinc preparations to prevent or treat respiratory infections. My take on this entire line of products is two thumbs down. I have nothing against the principle. There are no facts that document its safety or efficacy, just word of mouth.
