People complain all the time about faults in their physical appearance. Those blemishes on the skin can be indicative of pathology deep within. Subtle changes in the color, shape or coating of the tongue can reveal dystrophy of specific tissues, organs and systems. Ridges, spots and other abnormalities of the nails are reflective of certain diseases and nutritional deficiencies.

The text includes other signs and symptoms for each deficiency, as well as rich food sources of the nutrients, diets to aid in the healing process and suggested augmentations with food-based nutritional and herbal supplements. The information in this book is taken from a variety of medical and nutrition text books plus peer review articles which are referenced in the footnotes. This 164 page manual includes 45 color medical illustrations and four easy-to-use reference charts. It is an essential reference book for all doctors, health professionals, diagnosticians and holistic minded individuals.
