What should I do if an infant or toddler's tongue turns blue?

Patient's question:

No

Doctor's answer:

The tongue is cyanotic. On one hand, it is necessary to rule out the possibility of stained tongue caused by diet or medication. On the other hand, it should be considered as an external manifestation of organic lesions. In Traditional Chinese Medicine (TCM), the heart opens into the tongue. If the tongue body is cyanotic, the primary consideration should be cardiac disorders. If the tongue coating is cyanotic, it can be diagnosed by differentiating the zang-fu organs.
