Chao Yuanfang stated: The Heart manifests in the tongue and governs blood; the collateral vessels of the Spleen also emerge from under the tongue. The Heart and the Spleen are mother and child organs (the Heart is the mother, the Spleen is the child). When heat pathogens are present, both blood and Qi become hyperactive. The manifestation is a swelling attached to the underside of the tongue near the root, shaped like a tongue but shorter, named Chong She (Double Tongue). Methods for cutting it off with fingernails or reed knives can be found in the preceding section on "Mouth Wiping Method." The *Huiyan Jing* records that E Kou (Goose Mouth), Chong She (Double Tongue), Chong Yin (Double Gums), and Kou Chuang (Oral Ulcers) are all caused by Heat in the Upper Jiao, resulting from excessive heat exposure during fetal development. One should immediately apply powdered Ji Nei Jin (Chicken Gizzard Lining) dry into the mouth, as well as apply Zhu Sha Gao (Cinnabar Ointment) and Di Huang Gao (Rehmannia Ointment) alternately, while still administering Tian Zhu Huang San (Bambusae Caulis in Silicea Powder).

Mr. Mao stated: For stagnation due to Heart Heat, first apply Zhu Sha Gao (Cinnabar Ointment; see Fright Accumulation Chapter) to the tongue, then apply Niu Huang Gao (Calculus Bovis Ointment; see Diaphragm Heat Chapter).
