Shrink Your Cold Sore

Shrink Your Cold Sore with Preparation H. . . (Really!)
I haven't seen this written anywhere, but if I feel a cold sore coming on, I use a Preparation H suppository - not the cream, but the individually-wrapped suppositories.
Peel back a little of the outer wrapping and apply to the swelling cold sore often throughout the day.
I have no scientific proof that this works, only personal experience. Preparation H is supposed to shrink swelling. I contend that it does - on cold sores as well as hemorrhoids.
P.S. Try not to lick your lips and refrain from using just before eating. It may not be good to ingest it.
