The tongue is the sprout of the Heart. The Heart belongs to Ministerial Fire (Jun Huo), and its nature is inherently hot. Moreover, infants possess a pure Yang constitution, inheriting heat from the womb and easily contracting external heat postnatally. The occurrence of E Kou (Goose Mouth) and Chong She (Double Tongue) may not necessarily be due to the infant's own pathology but could stem from maternal factors. Ancients said, "To keep an infant safe, often let them be hungry and cold." Hunger prevents damage to the Spleen, and cold prevents the generation of internal heat. This is the way to nurture infants. The term "cold" here does not mean freezing the infant, but merely maintaining a normal temperature, avoiding excessive warmth. With appropriate temperature regulation, how could one suffer from E Kou or Chong She?
Why is it called "Chong She" (Double Tongue)? "Chong" refers to swelling and protrusion under the tongue, resembling an extra layer; thus it is called double, not that there are literally two tongues. Why is it called "E Kou" (Goose Mouth)? E Kou describes a condition where the entire mouth is white, resembling the inside of a goose's mouth, commonly known as Snow Mouth.
Analytically, Chong She belongs to the Heart, while E Kou belongs to the Spleen; collectively, they are attributed to Heart Heat. Why? Because the Heart governs the Spleen (in this context implying their interconnectedness in oral pathology), hence the disease manifests in the mouth. If it were not due to Heart Heat, although the mouth might appear white, the tongue itself would be red. How could the tongue be entirely white?
The general treatment principle is to internally administer formulas that drain Heart Heat and externally apply cooling medications. In this way, Chong She can subside, and the white coating can recede.
