Ethanol is a naturally occurring substance, humans and many animals have specifically evolved ways of processing it. In moderate doses it does no harm.

It's almost impossible to avoid ingesting some alcohol during the course of a natural diet, and that includes if you avoid fermented food such as bread, let alone beverages deliberately brewed to be alcoholic.

And if you have one of those poisons the antedote is the other one.

Edit: only one way round! This is not medical advice. I am not a doctor. I am not your doctor or drinking doula.
