Evolution is Impossible....

The only thing you got right is Syrup of Ipecak (or something).

And I'm pretty sure that makes you puke because it's so bitter you can't handle it. I don't know if it's actually tar. I do know it doesn't make you puke because it's an antibiotic though. Even if it is an antibiotic, that's not what it's used for, as you won't keep it in your body.
