Question:
What are the causes of cold sores in the mouth?
Are there any home remedies for cold sores?
Answers:
It's caused by a variety of the Herpes virus. I have never heard of home remedies, although there are prescription ones that work.
The virus is with you for life, so expect outbreaks whenever you are stressed or your immune system is weakened.
