INFOGRAPHIC: WHAT DOES YOUR TONGUE SAY ABOUT YOUR HEALTH?
From
web site
"Open your mouth and look at your tongue. That may sound strange, but your tongue can tell a lot about your health. For example, a black and hairy looking tongue can signal poor oral hygiene, or diabetes. If your tongue is bright red like a strawberry, it could signal a deficiency in folic acid, vitamin B12, or iron. But, it could also mean you have strep throat, or a fever."
