The white half moon found at the base of your nails is medically referred to as lunula.
According toBright Side, you should always keep a watchful eye on the shape of your lunulae.
You also need to be aware of any changes in color.

While white suggests you are in good health, any other color could be a sign of something serious.
Black, for example, is known to indicate heavy metal poisoning.
Ultimately,Bright Sideclaims that the lunula on each finger is connected to a different part of your body.
