Pharyngula

It’s called Zicam Cold Remedy Nasal gel. Unfortunately, it doesn’t do a thing for colds…all it can do is destroy your sense of smell. It wasn’t caught before it was put on the market, because, get this:

The FDA said Zicam Cold Remedy was never formally approved because it is part of a small group of remedies that are not required to undergo federal review before launching. Known as homeopathic products, the formulations often contain herbs, minerals and flowers.

Minerals. Like lots of zinc, which can cause nerve damage.
