A picture paints a thousand words. It might not be the first thing on your mind when simply looking upon someone's facial features, but a hard-wired part of our brain is busy making assessments and taking notes. From a deep psychological and evolutionary standpoint, we can observe a vast amount of information: the health of every organ, their mental state, their medical history, just from observing a face. The tongue and the pulse are also fascinating diagnostic tools from which we can tune into the body’s many whispers. Let's introduce the key ancient practices in Chinese Medicine examination.

This article is for educational purposes only and is not a substitute for professional medical advice. Traditional Chinese Medicine (TCM) techniques like tongue diagnosis, face mapping, and pulse reading are ancient practices and should not replace conventional medical evaluation. Always consult a healthcare provider for any health concerns or medical conditions.


The Body is Talking: TCM’s Diagnostic Toolbox

Your body speaks volumes, and Traditional Chinese Medicine (TCM) has spent millennia learning how to listen. But don’t expect high-tech machines or blood tests here. TCM practitioners go deeper — right into the parts of you you’d probably never expect: your tongue, your face, and even your pulse.

Thought your tongue was just for tasting? Think again. In TCM, the tongue is viewed as a map of your body’s internal health. Each section reflects a different organ, and practitioners assess its colour, shape, and texture to gather clues about potential imbalances.

A “healthy” tongue? Smooth, moist, pink, with a thin white coating. If it doesn’t look like that, it may suggest something is off.


  • The Tip : This area is linked to the heart and lungs. A red or swollen tip could indicate emotional stress or respiratory concerns.

  • The Sides : Associated with the liver and gallbladder. If the sides of your tongue have scallops or tooth marks, this might suggest your liver is under pressure.

  • The Centre : This area typically corresponds to the stomach and spleen. A thick coating here could point to long term digestive issues.

  • The Back : Connected to the kidneys, bladder, and intestines. Imbalances in these organs might show up here as irregularities.

Pizzorno and Murray's Textbook of Natural Medicine states that a healthy tongue surface is covered with papillae providing the characteristic texture. Variation in these papillae may be seen by the TCM practitioner as an indication of imbalance.


  • Qi Deficiency : A pale, swollen tongue with tooth marks may indicate low energy. Fatigue and general weakness could be linked to this pattern.

  • Yin Deficiency : Cracks on a red tongue with minimal coating are thought to suggest internal heat, with possible symptoms like night sweats and insomnia also presenting.

  • Yang Deficiency : A thick white coating on a pale tongue might point to a lack of internal warmth — possibly explaining why some people feel cold and tired all the time.

  • Blood Stasis : A purple tongue with black spots could indicate blood isn’t circulating efficiently, potentially linked to cold limbs or varicose veins.

Face Mapping: Your Facial Features Tell a Story

Your face is typically described as the mirror of your interior body. This is also a concept now recognised in Western holistic healthcare practices, although with varied levels of complexity.


Practitioners specialising in TCM use face mapping to learn how internal organs may be affecting the skin. In theory, different parts of your face correspond to a variety of organs. Observed changes in these areas could suggest imbalance. Here are some examples of what may arise from an examination of the face:


  • Forehead : Tied to the digestive system. Bloating, indigestion, or constipation might show up as breakouts or redness here.

  • Cheeks : Associated with the lungs. Respiratory issues or a weakened immune system could manifest as skin changes on the cheeks.

  • Nose and between brows : Linked to the liver. If this area is breaking out or looking inflamed, it might suggest your liver is under strain — potentially from stress or dietary factors.

  • Chin and jaw : Thought to reflect the reproductive system. Hormonal imbalances, such as those caused by menstruation or stress, might appear here as spots or discolouration.

Pulse reading: Listening to The Rhythm of Your Health

While tongue and face diagnostics provide visual clues,  pulse reading  is used in TCM to assess the internal flow of Qi (energy) and blood. Practitioners typically feel for the pulse at three points on each wrist, with each point thought to correspond to different organ systems.


Unlike Western pulse readings that focus on rate and rhythm, TCM pulse diagnosis goes deeper — paying close attention to the strength, depth, and quality of the pulse. Whether the pulse feels ‘wiry’, ‘slippery’, or ‘weak’ is believed to give a practitioner insights into potential imbalances.

So, What is Your Body Telling You?

Health in Traditional Chinese Medicine is generally viewed as a balance of Yin and Yang, Qi, and blood. When this sensitive balance is disrupted, the body may send signals that can be visually or palpably perceived. The different techniques used by the practitioner of TCM to interpret the signals include diagnostics in the tongue and face, and pulse reading.


Although these techniques are not substitutes for conventional medical tests, they may provide a complementary perspective on your health. Exploring ancient practices like acupuncture, alongside these diagnostic tools, could help you tune in to what your body’s trying to communicate to you.


Traditional Chinese Medicine offers much more than diagnosis — with dietary advice, herbal treatments, and moxibustion, it seeks to restore balance in a truly holistic way. By paying attention to the subtle cues your body provides, these time-honoured practices offer everyone an alternative approach to modern Western medicine.
