Warning! Scary message from an Olde Farte.
If you use alcohol based mouthwash, and have kids, keep it away from them. Some brands were/are 20% alcohol (equals 40 proof). Had an eight year girl who saw Mom/Dad use it, used it herself and DRANK half the bottle. Ended up in our ER, unconscious and unresponsive, with acute alcohol poisoning. Spent the night in the ICU. Not good.
