Ever been to a TCM (Traditional Chinese Medicine) doctor or an acupuncturist and been asked to stick out your tongue? There is a reason for this. TCM believes the tongue is a microcosm of the entire body and will reflect its excesses and deficiencies. The shape, colour, coating, and texture of the tongue can all indicate digestive issues and body imbalances.
The gold standard: A normal healthy tongue is pink in color, has a light white tongue coating on it, and is proportionate in size to the mouth.
