Does the FDA regulate OTC canker sore medication? If so, which
monograph pertains to canker sores? Is there a regulation on copper
sulfate for use in canker sore medicine? (Ora 5, for example, is sold
over the counter and contains copper sulfate) If copper sulfate is NOT
in a monograph for canker sores, is copper sulfate "generally regarded
as safe and effective" (grase)? Or is it simply overlooked by the FDA?
Also what's the story with other natural or "herbal" canker sore
medicines that are clearly not part of a monograph or a new drug?
