On my recent trip to India, two of the specialist doctors I consulted for Gout at SHALBY, Amdavad first and foremost checked my fingernails and with the formation of slight ridges on my finger nails indicated my lack of Iron (which was proved with positive with the blood test) and of course early stages of Arthritis…..
As far back as 3,000 BC Chinese physicians studied their patients fingernails for telltale signs of illness.
Thousands of years later, American country doctors, tending to their patients in small towns and farm villages, routinely checked patients' eyes, the surface of the tongue, and the appearance of the fingernails.
Some knowledgeable practitioners still check these things, although most that do are doctors that practice holistic medicine.
Why did the ancients and the old-time country doctors take such an interest in their patients' fingernails?
Because the nails often signal the presence of serious internal diseases, many that could become life threatening if overlooked or left untreated.

Have you checked your nails lately?
It may seem like an a strange question, but actually it's not. The condition, strength, and color of your nails are good indicators of what's going on inside you that you can't see.
Holistic physicians analyze the nails and you can too, if you know what to look for when you check them. It's a good idea to check your nails periodically (at least several times a year) to get an early warning about anything that may be dangerous cropping up inside you.
