Nail


NAIL
In medicine, there are two types of nails. One is just a plain old metal nail used to hold two or more pieces of bone together, such as, after a fracture. The other type of nail is the horny plate on the end covering on the upper surface of the tip of the finger and toe. Anatomically each nail has a body, lateral nail folds (on the sides), a lunar (the little moon white – shaped feature at the base), and a proximal skin fold (at the base).
In order to assert a perfectly manicured hand is one where the nails are smooth, soft and strong, with no discoloration, jagged cuticles or other signs of abuse. Since many health problems have an impact on the nails, it’s worth giving attention to what one’s hands have to say.
Ridges – Potato chips aren’t the only things that can have ridges. Nails that have even, vertical ridges are totally normal—a sign not of any health problems, but of age (they tend to become more accentuated as you get older). But a condition called Beau’s lines is a sign of a more systemic health issue. “If a person has been very sick or gone through a lot of stress, the nail may stop growing. “When it starts growing again, an indentation occurs at that spot on the nail.” As the nail grows out over the next several months, these indentations (probably in about the same place on each nail) will become visible. A single deep ridge in just one nail may show that there’s a small wart or cyst at the base of the nail that is putting pressure on the nail matrix and affecting the way the new nails grow.
Looking yellow – A healthy nail (with healthy skin beneath its bed) has a pretty, pinkish hue. When it doesn’t, that may be a reason to worry. “When all of the nails turn yellow it can be a sign of lung disease or diabetes. “Yellow spots on the nails can be an indicator of fungus or psoriasis.” Since any of these conditions warrants treatment by a doctor, it’s worth seeing a dermatologist if yellow nails persist. Women who often wear very dark nail polish for long periods of time (especially without using a protective base-coat underneath it) may also notice a slight yellowing of their nails, but it’s no reason to panic. The nails are merely stained from the polish and will return to their normal shade if they are left unpolished for a while.
Though, energy in nails zero Neuto and circular Neuto meridian that is located in the periungual area of the nail. The Nail syndrome indicates virility, and immune system of a person. Or otherwise can be considered if nails are pale indicates blood deficiency. The other syndrome of yellow nail may be mycelia, pyogenic, paronychia, nail eczema, in all the cases humidity energy dominant, which controls that.
In any case one should take remedial aspect, but acupuncture SuJok ‘Onnuri Medicine’ too is capable to give positive results in case even of lung disease or diabetes or improved immunity.
