I am curious to see if that mouthwash trick works. Is it the minty kind of mouthwash or the more mild stuff?
Rinsing your mouth with hydrogen peroxide helps get rid of canker sores. It works better than mouthwash.
I saw a show once in which a dermatologist said that if she could only have two items to treat skin conditions, they would be vaseline and alcohol. Her advice was if it is wet, use alcohol to keep it dry. If it is dry, use vaseline to keep it moist.
Best thing for cold sores. Apply alcohol several times a day and take 1000 to 3000 mg. of lysine a day until the cold sores are gone. It works better than any remedies you can buy.
Best way to give your dog a pill: coat it in cream cheese.
