Split lip help?

Man, I’ve got this one thing driving me absolutely nuts. So, I was at MMA training today, right? We were doing some sparring rounds and somehow—don't ask me how—I managed to bite the absolute hell out of the inside of my lip. Like, I actually bit a tiny little hole right into it. Now there’s this annoying little white blister sitting there, just being a total nuisance. A buddy of mine, who’s been through the ringer with busted lips before, told me he used some kind of sage extract drops to make the white stuff disappear instantly. Does anyone know what those drops are called, what they run for at CVS or Walgreens, or who actually makes them? If you've dealt with this crap before, please help me out. It's seriously getting on my nerves; I can barely even talk to people without feeling self-conscious about the top of my lip. :S

It's called Api Dent. You just dab it on the right side or wherever the gum is sore about 2-3 times a day. It costs $20. Should clear things up in a day or two, though it stings like hell :S. Also, grab some Heparin cream for the bruising.
