Die Zunge ist ein unglaublich wertvoller Indikator für den Gesundheitszustand, der die Rolle einer Art durchsichtigen Wand für die inneren Organe spielt. Eine Zunge in guter Verfassung sollte glatt, weich und leicht feucht sein und einen blassen roten Farbton haben und mit einer sehr dünnen Schicht weißer Substanz bedeckt sein. Besorgniserregende Symptome auf der Zunge umfassen Risse, Schmutz, Belag (gelbe, dicke, weiße, felsige), Linien, Knoten sowie rote Flecken und Wunden.
A topographic atlas of the tongue
As per traditional Chinese medicine, alterations in the tongue's appearance in specific zones are not coincidental and warrant attention. A topographic atlas of the tongue illustrates the correlation between distinct tongue regions and internal organs. Deviations in the tongue's muscular composition, such as color shifts or the presence of coatings, may signal dysfunction in particular organs. Consequently, the examination of the tongue's surface, its hue, coatings, as well as the size and sensitivity of taste receptors holds significance.
The examination of the tongue surface
A cracked tongue may indicate cellular dehydration and overly thickened blood, potentially increasing the likelihood of stroke or blood clot formation. A tongue with irregular light and red patches (geographic tongue), lacking papillae in certain areas, might suggest oral fungal infections, vitamin deficiencies, or allergic responses. This condition is also observed in individuals with leukemia and psoriasis. A deep central groove on the tongue could signify gastrointestinal disorders, digestive issues, or excessive stomach acid production.
Tongue color as a health indicator
A tongue in optimal condition exhibits a gentle or moderate pink hue. Conversely, a vivid red or purple hue on the tongue often suggests an elevated body temperature due to inflammation or infection, but may also indicate blood clots in the organs or vitamin deficiency. A light red tongue also signifies a high body temperature, but one caused by the consumption of overly spicy foods. The red discoloration of the middle portion of the tongue frequently appears in individuals with poor nutrition, a tendency toward obesity, or those attempting weight loss. An intensely red tip of the tongue may be a sign of chronic stress and commonly occurs in anxious individuals with sleep disturbances (if the tongue is swollen, it may contribute to cardiovascular conditions). A red tinge along the edges of the tongue may suggest impaired liver function. A pale, nearly white tongue may indicate hypothermia, anemia, or a weakened cardiovascular or immune system. A black discoloration of the tongue (regardless of location, though often visible at the base) typically points to renal dysfunction.
Excessive tongue coating
The tongue is naturally coated with a thin, clear layer of fluid. An excessive amount of white discharge may indicate body cooling due to slowed metabolic processes (often occurring in autumn). Grey discharge accompanies infectious diseases with fever. A grey tint can also suggest digestive disorders, acidosis, or liver diseases. A brownish hue on the tongue may appear in smokers. This indicates respiratory dysfunctions leading to oxygen deficiency. Yellow discharge may occur in hot weather (sign of overheating) or with excessive coffee consumption or spicy seasonings. This color can also point to peptic ulcer disease. A thick, greenish coating in the liver area signals liver weakness. Additionally, thickenings and changes may develop. A shift from darker to lighter coloration after illness signifies recovery.
A painful and irritated tongue
Tongue pain is frequently associated with deficiencies in nutrients such as iron, vitamin B6, or vitamin PP. A burning sensation in the tongue, on the other hand, may indicate insufficient digestive fluids in the stomach. This symptom can coincide with gastrointestinal issues. Additionally, it is important to note that medication use can affect the appearance of the tongue. Hormonal medications may cause redness and swelling, while dehydrating drugs can lead to grooves and a "polished" tongue appearance. After taking anti-inflammatory and pain-relieving medications, red spots may appear. Certain antibiotics damage taste buds, resulting in loss of taste and appetite.
