Do not know what's in the nail polish... but sounds like a lot of ingredients!!
What I did was using the Sabah Snake Grass. SUPER BITTER. smash or grind a few of them. can mix with water, dab on the fingers with a cotton. Dab over whatever that they put in the mouth. Thumbs, fingers, pacifiers, bolsters, toys, pens, etc... it work wonders. Natural summore... only 2 ingredients: Leaves and water!
