The lunula is very important to your nail and should not be damaged. If it’s blue, it could indicate diabetes. But what is the Lunula?
The lunula is that white part of your nail that is closest to the finger. It is usually white, and this is because it “hides” the blood vessels underneath.
Chinese medicine has long known a link between the lunula and health. The less lunula you have, the less energy you have, and no lunula means you are suffering from malnutrition.
