According to the *Taiping Shenghui Fang* (Imperial Grace Formulary of the Taiping Era), Lung Qi connects with the nose, and the nose is the external manifestation of the Lung. If an infant's diet of milk and food is irregular, causing stagnation in the Upper Jiao (Upper Burner), it leads to "Gan" parasites (parasites associated with malnutrition/toxicity) ascending to erode the nasal cavity. The symptoms include redness and itching in the nose, high fever with frequent crying, dry and scorched hair and skin, emaciation, coughing with rebellious Qi, irregular diarrhea, and sores with redness and ulceration extending from below the nose to the lips; hence it is called Nasal Gan (Nasal Parasitic Disease).
