According to Chinese medical philosophy, certain areas of the tongue reflect the health of internal organs.
The tongues coating and body are then analyzed for specific diagnosis. Doctors assess coating characteristics such as color, quality and density, and consider physical traits including firmness, color and size. A normal coating is thin, white and clear, says Cao, whereas a healthy tongue body is firm, red and fits well in the mouth. Deviations suggest something amiss.
Very simply, a white coating indicates excess cold, yellow denotes heat, and darker colors such as gray, green or black suggest internal toxicity. Thicker coatings spell more serious health problems, and a sticky coating may mean your insides are damp. A pale tongue suggests cold; red implies heat. Together, such clues can translate to diagnosis and remedy. For instance, a white, sticky, thick coating denotes a cold. A tiny, pale tongue is a classic sign of anemia while yellow, sticky coatings on both sides of the tongue point to hepatitis.
"If you look at your tongue," says Cao, "look for changes in coatings colors too white, yellow, gray or black. The tongue is naturally the same pink-red color as the lips. If its too pale, it may indicate an imbalance."
Problems such as chronic acne, pimples or dryness often point to nutrient deficiencies, says Gittleman, because the skin is the last organ to receive vitamins and minerals. Breakouts on certain areas of the face may also indicate associated organs are working overtime and your body is being swamped with toxins.
"Skin acts sometimes as a secondary elimination route for either the intestines or the liver, which are intimately connected with the removal of bodily water," she says.
"In conjunction with more traditional testing, facial diagnosis is a wonderful adjunct," adds Gittleman. "You dont have to take it seriously," she says, "but Ive found that it works."
Also modeled on the Chinese philosophy that outward characteristics represent inner organs, iridology proposes that the color, texture and markings of the iris the colored area around the pupil can indicate health and disease.
According to iridology proponents, eyes color corresponds to an individuals constitution and affinities for certain types of health problems.
Iris analysis hints at a persons health leanings and dietary needs, adds Tart. "Its not for someone who wants a quick fix." For more information on iridology and to find a practitioner near you, log on to the website www.iridologyassn.org.
