I've never v'ed from it or known anyone that has. I get nauseated when I get a fever (it's just me-no one else I know does) but that's about it.


And yes, that icky stuff draining down your throat is not digestable, so if too much of it gets in your tummy, it can make you sick. But, I've had AWFUL sinus infections and pnuemonia and haven't gotten sick from the phlem.
