Only shortly after moreless posted the information about Milk of Magnesia in the post linked above, I came down with a sore throat. I then got a hold of a bottle of Phillips "Original" MoM and gargled with a small amount to see if it will help with my sore throat. Only hours later after the MoM treatment, my sore throat was noticeably better. The next day, yesterday, my sore throat was completely gone... COMPLETELY!
All I can say is WOW. Whodathunk to use a laxative to treat sore throats? I sure didn't, but I'm glad that I now have a new weapon in my arsenal against infections in the mouth and head area.
