Tongue coating
Quality of the tongue coating : Thin or thick, can be considered and understand the severity of the pathogenic factors. Thin tongue coating is present if superficial portion of the body is affected in a disease, or if the disease is due to deficiency of the anti pathogenic qi. It may be retention of food or phlegm in the interior, or inward transmission of pathogenic factor from the exterior, and is a sign of aggravation of the disease.
Moist coating and dry coating : It indicates body’s fluid by distinguishing the moisture and dryness of the tongue coating. A normal tongue is moist and lustrous whereas dry looks coarse and feels lacking moisture indicates consumption of body fluid due to excessive heat or consumption of fluid. If there is an excess moisture, the saliva dribbles whereas in sever case, it is a slippery and the condition is caused by upward flooding of harmful water and damp.
Sticky coating and granular coating : It reduce the turbid damp in the intestines and stomach. A sticky tongue coating is often seen in syndromes resulting from retention of turbid damp and phlegm or retention of food. In granule tongue surface are coarse, loose and thick like residue of making soy bean curds, and easily scrubbed. A pastry tongue coating often results from excessive heat bringing the turbid qi in stomach upwards.
Peeled coating : The tongue with a part of its coating peeling off is know as geographic tongue. It is a sign of consumption of qi and yin of stomach. If the entire coating peels off leaving the surface mirror smooth, the condition is known as glossy tongue. It is a sign of exhaustion and sever damage of stomach.
Color of the tongue coating ;
 White Coating : A thin and white coating is normal. Yet a white coating may appear in an illness. If so, it indicates exterior syndromes and cold syndromes. A thin and white coating is present in exterior cold syndromes, whilst a thick white coating is seen in interior cold syndromes.
Yellow Coating : It indicates interior and heat syndromes. The deeper yellow the coating is the more severe pathogenic heat it indicates. A light yellow coating point to mild heat; a deep yellow coating to severe heat; a burnt yellow coating is accumulation of heat.
Grey Coating : It indicates interior heat syndromes or resulting from cold and damp. If grey coating is yellowish and dry, it signifies consumption of body fluid due to excessive heat. If it shows whitish and moist, it implies retention of cold damp in interior or retention of phlegm and fluid.
Black Coating :It is interior syndromes due to extreme heat or excessive cold which appears in case of sever illness.
Precautions ;
As conditions of the tongue and its coating are manifestations of interior complicated pathological changes. The conditions mainly reflext deficiency or excess of organs and strength of the essential qi.
It is desirable to observe the tongue in direct natural light. The patient is required to protrude the tongue naturally.
Some food and drugs may color the tongue coating and the thickness and moisture of the tongue coating may change after eating or scraping the tongue. Attention should be paid to the exclusion of false phenomena induced by such factors in the clinical situation.
In normal course if a person’s tongue move freely inside the mouth without opening the mouth means heart is healthy!

Diagnosis ; tongue to help in giving cure results, which is an important aspect in diagnosis by inception. It indicates primary information of the disease to make diagnosis.
Acupuncture ‘SuJok’ energy says tongue is directly or indirectly connects with many organs through the meridians and collaterals. The deep branch of the Heart meridian goes to the root of the tongue; and the Spleen meridian traverses the root of the tongue and spreads over its lower surface; the Kidney meridian terminates at the root of the tongue. So the essential energy of the organs can go up to nourish the tongue, and one can at the same time see pathological changes of the organs which show by changes in tongue conditions. This way one may observe the pathological changes of the internal organs.
There is easy way to see the tongue properly and its coating. The proper tongue refers to the muscular tissue of the tongue, which is also sign as the tongue body. The tongue coating refers to a layer of ‘moss’ over the tongue surface, which is produced by the stomach qi.
A normal tongue is considered to be of a proper size, soft in quality, free in motion, a thin layer of white coating with slightly red or pinkish in overall color which is neither dry nor moist in excess.
The tongue may be divided while diagnosis into four parts, namely, tip, central part, root and border. The tip of the tongue often reveals the pathological changes of the heart and lung, and its border area reveals those of the liver and gall bladder; its central part reveals those of the spleen and stomach; and tongues root reveals to the kidney place. This method of diagnosing the pathological changes of the organs by dividing the tongue into corresponding areas is clinically significant.
Tongue diagnosis ;
Proper: This is to see the color and form of the tongue proper ~
Color of the tongue proper – Pale tongue : If a tongue appears to be pale means less red than a normal one, indicates syndromes of deficiency type and cold syndromes of the organs caused by deficiency or insufficiency of the qi and blood.
Red tongue : A red tongue is bright red and redder than a normal tongue. It indicates various heat syndromes including interior heat syndromes of excess type and interior heat syndromes of deficiency type due to deficiency.
Deep Red tongue : A deep red tongue indicates extreme hotness condition. Normally in exogenous febrile diseases, which indicates invasion of the blood systems by pathogenic heat. In endogenous diseases it indicates deficiency leading to the hyperactivity of fire.
Purple tongue : A blue purple tongue indicates stagnation of the blood which is related to either cold or heat. A deep blue purplish tongue, dry and lusterless, is related to heat, whilst a pale purplish and moist tongue is related to cold. While the purplish spots presence on the tongue surface indicates stagnation of the blood.
Form of the tongue proper :
Swollen tongue : A swollen tongue is larger than the normal. If a swollen tongue is delicate in quality and pale in color, and with tooth prints on the border, it indicates deficiency of the spleen and kidney. The condition may be due to impaired circulation of body fluids producing harmful water, retained fluid, phlegm and damp. If a swollen tongue is deep red in color occupying the entire space of the mouth, it indicates excessive heat in the heart and spleen. But if tongue appears to be bluish purplish and dark, it indicates toxics.
Thin tongue : A thin tongue is smaller and thinner than the normal one. A thin and pale tongue indicates deficiency of qi and the blood. A thin, dry and deep red tongue indicates hyperactivity of fire due to deficiency in which body fluid is consumed.
Cracked tongue : Irregular streaks or cracks on the tongue indicate excessive heat consuming body fluids.
Sore spots : It may be small but can occur anywhere in the mouth ,including the tongue which are excessively painful. It may happen due to multi factors – such as having a cold or fever, eating an excess of citrus fruits, or biting the tongue. But a normal canker will heal up and vanish in a week or so. Something that lasts longer and doesn’t seem to be going away could be a sign of oral cancer.
Thorny tongue : The papillary buds over the surface of the tongue swell up like thorns. A thorny and red tongue indicates accumulation of pathogenic heat in the interior. The more sever the pathogenic heat is, the more enlarged and profuse the thorns will be.
Deviated tongue : A deviated tongue indicates wind stroke or likely to be threatening signs of wind stroke.
Rigid tongue : A rigid tongue lacks flexibility and is difficult to protrude, retract or roll. A rigid tongue seen in exogenous febrile diseases which often indicates invasion of the pericardium by heat, retention of turbid phlegm in the interior or excessive pathogenic heat consuming body fluid. A rigid tongue present in endogenous diseases indicates wind stroke or early threatening sings of wind stroke.
Flaccid tongue : A flaccid tongue is weak in motion and often indicates extreme deficiency of qi and blood or consumption of fluid depriving the tongue to nourish. If a flaccid tongue is pale, it indicates deficiency of qi and blood. If it is deep red, it indicates collapse of the organ.
