Studying the nails can accurately reveal many diseases. Many doctors today look closely at a patient’s nails as part of this section of palmistry. Nails clearly point to hereditary diseases, especially those of the heart, spine, lungs, and nerves. Nails are divided into 4 types: Narrow, Short, Broad, and Long.
Long Nails
If your nails are very long, they are never as strong as medium-sized nails. If you have Long Nails, you tend to be prone to chest and lung disease. If the nail is fluted or ridged, with ridges running from the bottom to the top, you may suffer even more. A similar but smaller nail shows a tendency toward throat problems, such as inflammation of the throat, laryngitis, and bronchitis. If your nails are blue, this shows poor blood circulation.
Short Nails
If your nails are short, this shows a tendency toward weak heart action, especially when the moon (the pale half-circle) at the base of the nail is very small. If the nails look very flat and sink into the soft tissue at the base, this shows nerve disease. If the nails have ridges running from left to right, this shows greater danger. If a deep furrow appears across the nails, this shows sudden illness of the nervous system. By studying the rules of palmistry, you can work out when an illness occurred. A nail takes about 9 months to grow out from the base. Because of this, you can divide the nail into sections to date an illness. If a deep ridge or furrow appears near the tip of the nail, the illness happened about 9 months ago. If it appears in the middle, the illness happened about 4 to 5 months ago. If it appears near the base, the illness happened about 1 month ago. White spots on the nails are a sign of general weakness. If a nail is covered in tiny white spots, your health is very poor and your nervous system is very weak.
Long Narrow Nails
If you have long, narrow nails, this shows a weak spine. If the nail is very bent and very thin, this shows curving of the spine and great overall weakness.
Flat Nails
If your nails become very flat and start to lift away from the soft tissue at the tip, this shows a risk of paralysis. This is even clearer if the nail curves like a shell toward the base. If the nails show no moons at all and are blue or white, this shows the disease is at an advanced stage.
The Moons of the Nails
If you have large moons on your nails, this shows strong heart action and fast blood circulation. If they are unusually large, this shows too much pressure in the heart, and a very fast heartbeat. The valves are overworked, with a risk of blood vessels collapsing in the brain or heart. Small moons show the opposite: poor blood circulation, anaemia, and a weaker heart. As death approaches, the moons are the 1st part of the nail to turn blue. Later, the whole nail turns blue, or almost black.
