A physician can tell much when she looks at your nails – if she was trained well. The nails can show fungus and other specific nail diseases. But many internal diseases show also at your fingers and nails – and other than the tongue, which in Traditional Chinese Medicine is used to diagnose diseases, the fingers are usually not hidden, and I don’t have to ask a patient to show me his tongue.
By the way, Sebastian Kneipp used to gauge the health of a person by ear diagnosis – also freely to be inspected. One anecdote goes that he gave Pope Leo XIII another nine years, when the Pope already was at the ripe age of eighty-eight. Sure enough, the Pope died at ninety-seven – and had a chance to implement some of his social-minded reforms. Leo XIII was one of the most progressive of popes.
Of course, fingers, tongue, ears – there’s no hocus-pocus involved: Any part of your body is affected by the same age, the same experiences, the same nutrition and, usually, by the same disease. No wonder then that an experienced observer can tell much from them.
Some of the diseases I recognize by nails: Liver disease, iron deficiency, chronic autoimmune inflammation, arthritis, psoriasis, gout, a bad infection or severe stress that happened months ago, circulatory diseases, Kawasaki disease, a sluggish or overactive thyroid, certain heavy metal poisonings, skin diseases (even sometimes a melanoma under the nail – so-called subungual melanoma), vitamin B12 and C deficiencies, lung and heart disease, impaired kidney function, folate deficiency, malnutrition (protein deficiency), nail injuries, use of certain antibiotics, and so on.
Having said this it is obvious that we doctors don’t encourage artificial nails and nail polish – it takes an important diagnostic tool away from us! This list also alarms you that changes in your nails should be examined by your doctor. But sometimes one has only “ugly” nails, with now apparent reason – perhaps brought simply on by the aging process or dirty work. Here is a nice simple method to make your nail beautiful again:
• Keep fingernails short by filing with an emery board, never by cutting (toenails should be cut straight).
• Wash and brush hands and nails with a soft brush and a non-harsh soap. I prefer olive oil soap.
• Apply tea tree oil to the nails thinly; rub it in.
• Apply olive oil with rosemary essential oil (other essential oils like oregano, lavender, myrrh work the same way) to hands and nails.
• If your hands are rough, apply coconut oil (the same organic grade that you use for cooking) regularly. Read More
