Say I was stranded on a desert island with Jennifer Lopez, a couple tond of MREs, and a big bottle of Lisretine. Further say that Jen’s chasing me on the beach lusting for more of my hot lovin’ and cuts her toe on a shell. Poor baby. 
After she has her bloody-toed way with me, would applying Listerine (to the toe, of course) do any good staving off infection?
Peace,

At about 20% alcohol content I would say yes. Just to be sure you had best both drink the rest of the bottle and give her a foot massage in order to get back to hot loving to take her mind off of the pain. 
I would be more interested in using the bottle to beat her away or at least save it to drink so that my beer goggles got thick enough to proceed.
If you really want to help her get better, it could help.
“First formulated by Dr Joseph Lawrence and Jordan Wheat Lambert in 1879 as a surgical antiseptic, it was given to dentists for oral care in 1895 and became the first over-the-counter mouthwash sold in the United States in 1914.”
It’s pretty cold when someone named Shagnasty kicks JLo to the curb on a desert island. :dubious:
Dang, Shag, you must be Da Bomb! It’s her big old butt, right? 
Given the choice between her and what’s-her-name from Friends, no contest IMO.
