Tongue diagnosis


Tongue diagnosis is a technique used in traditional Chinese medicine and traditional Indian medicine (Ayurveda) to diagnose disease or medical conditions.

There is no strong scientific evidence that tongue diagnosis is a reliable technique. It should not be used to diagnose and guide treatment in place of modern diagnostic techniques.
There isn't enough reliable information to know if tongue diagnosis is safe. While tongue diagnosis is a non-invasive procedure that has been used with apparent safety in some low-quality studies, this technique should not be relied upon to identify or diagnose medical conditions or disease in place of modern diagnostic techniques.

Tongue diagnosis is a technique used in traditional Asian systems of medicine including traditional Chinese medicine (TCM) and traditional Indian medicine (Ayurveda). It is often used in connection with pulse diagnosis. Practitioners of these systems of medicine evaluate the tongue for color and other qualities. They believe that certain tongue qualities correlate with energy imbalances or body fluid (humoral) imbalances in specific organs or areas of the body. Therapies are often guided by these tongue qualities. However, there is no reliable scientific evidence that tongue diagnosis is an accurate indicator of medical conditions or disease. has licensed monographs from TRC Healthcare.
