Nails are often referred to as the ‘barometer of overall health’. Everything one sees on the outside of the body is a reflection of something going on inside. The significance of nails as indicators of health status has been recognised as early as the 5th century B.C. when Hippocrates first described clubbing (a deformity of the nails) as a symptom of disease.
Healthy hair, skin and nails are an outward sign of health and vitality, and their poor condition may reflect many biochemical imbalances in the body. Hair and nails indicate the health of the body 2 to 6 months previously. This means that much of what is going on inside you will quickly be reflected in this organ system, collectively known as the integumentary system.
