Look at your fingernails, did you notice a white half-moon shape that starts at your nail beds? In fact, it is a very important part of the nail. That little area is called the “lunula,” Latin for “little moon.” and it’s more than just a built-in design element — it actually says a lot about your health.

In traditional Chinese medicine, the lunula is viewed as a barometer of one’s health. The condition of the lunula is an indication of your health. When your health declines, changes to the lunula may occur, or it may completely disappear. And when your health is restored, your lunula returns to its original condition.

WHAT DOES IT SAY ABOUT SOMEONE’S HEALTH — BOTH THE LACK OF IT OR THE PRESENCE OF IT?

Normal Lunulae

According to medical experts, having 8 to 10 milky white lunulas on both hands means that everything is alright with your health. The whiter the lunula, the stronger the health.

Low Energy and Weak Immunity

The fewer lunulae a person has, the lower their energy levels, overall health, and immunity. If you only have lunulae on your thumbs, it could indicate a lack of physical energy and make you more prone to getting sick.

Missing Lunulae

One study has shown that missing fingernail moons are associated with various systemic disorders, including issues with your thyroid or pituitary gland, iron deficiency, chronic renal failure, depression, and possible B-12 deficiency. If you have missing lunulae, it is important to have your iodine and Vitamin B-12 levels checked, as well as your thyroid function and blood pressure.

To sum up, the lunula is considered a sign of how healthy you are. Therefore, any change should be taken seriously and get checked.
