is a wonderful drug
which relieves oral wounds. I believe it is not addictive
and there are no known side effects to it (besides some hyper-sensibility issues).
It is composed of hexetidin, alcohol, mentol, eucaliptol (now I know why I like it), peppermint oil, citric acid and some other things (awful chemical translation by me... if you know better, /msg'me).
I do not know if Oraldine exists outside Spain, but if you find yourself here and in great oral pain, it could save your sanity. I know it has saved mine more than once.
