Crescent white, also known as lunula or little moon, is found at the one fifth position of the fingernail bottom and it looks like a curved white mark.
The normal fingernails should be ruddy, restrained, tough, arc-shaped, smooth and glossy with clear lunula which tells whether the person is energetic and healthy. The more energetic a person is, the whiter the lunula is; on the contrary, the lunula is poor and vague. In general, the lunula takes an area of about one fifth of the fingernail and has the clear edge. The lunula usually tells the disease of a person in the form of color change or disappearing crescent. After the person regains the health from regulation, the little moon will gradually appear again. In general, the less lunula a person has, the lower energy and poorer health and immunity he/she has, so it’s more likely for he/she to feel tired. If the lunula only appears on the thumbs, it indicates that the physical energy is insufficient and the disease is about to come.
Other factors shall also be considered comprehensively in judging whether a person is suffering from the certain disease, and there is no need to be panic about the change of lunula since the confirmation of a disease requires many inspections.
