1.4% Phenol: See the disturbing difference between new & old directions? FML

The old directions for Chloraseptic Spray said to spray in mouth, hold solution over the affected area for at least 15 seconds... and then SWALLOW. Now, it says to SPIT. I notice this after a week of use. FML! :/ I've also just now noticed that the lozenges don't have phenol. They use Benzocaine. *Sigh*
