I've never heard of the anti-freeze poisoning thing, but that's pretty interesting point.

As for OTC cought remedies, also is used in tiny quantities as a solvent, not as a central nervous system depressant as it is socially, or when it's used recreationally as.

Yes red wine can be cardioprotective, but the evidence supporting that is limited, and circumstantially dependent upon the amount consumed. Someone who drinks too much red wine puts themselves at risk for heart disease just like any other heavy drinker.

Although I'm sure the medical community will agree that there are lots of other naturally occurring more effective cardioprotective substances that could be consumed in it's place.
