Chao Yuanfang stated: "Infantile drooling" (Zhi Yi, accumulation of saliva in the chin area) refers to saliva flowing out and soaking the cheeks. This is caused by coldness in the Spleen leading to excessive saliva. The fluid of the Spleen is saliva; when the Spleen and Stomach are deficient and cold, they fail to control the body fluids, causing them to flow out and soak the cheeks. Zhang Huan advocated using *Wen Pi Dan* (Warm the Spleen Pill). Another method is to swallow *Bai Yao Jian* (Hundred Medicines Decoction), which naturally stops the saliva flow, serving as a method to intercept the pathogenic factor. *Yi Huang San* (Benefit the Yellow Powder) can also treat this condition, and *Wen Pi San* (Warm the Spleen Powder) may also be administered.

Zhang Huan's *Wen Pi Dan* (Warm the Spleen Pill) treats infantile drooling.
Ingredients: Banxia Qu (Prepared Pinellia Curd), Dingxiang (Clove), Muxiang (Aucklandiae Radix) (each 1 liang); Ganjiang (Dried Ginger), Baizhu (Atractylodis Macrocephalae Rhizoma), Qingpi (Green Tangerine Peel), Chenpi (Tangerine Peel) (each 0.5 liang).
Preparation and Administration: Grind the above ingredients into fine powder, mix with rice paste to form pills the size of millet seeds. For one-year-olds, administer 10 pills per dose; for two-year-olds, 20 pills per dose. Adjust according to age and severity, taken with rice soup.

*Wen Wei San* (Warm the Stomach Powder) treats infantile drooling, where saliva flows out and soaks the cheeks, also caused by Spleen coldness and excessive saliva.
Ingredients: Banxia (Pinelliae Rhizoma, processed), Renshen (Ginseng Radix et Rhizoma), Gancao (Licorice Root), Ganjiang (Dried Ginger), Roudoukou (Myristicae Semen), Baizhu (Atractylodis Macrocephalae Rhizoma) (each 0.5 liang); Dingxiang (Clove) (1 liang).

(*Lingyang Jiao Wan* (Antelope Horn Pill) treats infants aged five or six who cannot walk.)

Qian Yi stated: "Tortoise chest" (Gui Xiong) results from lung heat causing distension and fullness that attacks the chest and diaphragm, forming tortoise chest. Additionally, if the nursing mother consumes too much "five pungent spices" (Wu Xin), this disease can occur. "Tortoise back" (Gui Bei) occurs when postnatal exogenous wind invades the spine and penetrates the bone marrow after birth, forming tortoise back. The treatment involves applying turtle urine to the vertebral joints on the back. To obtain turtle urine, place the turtle on a lotus leaf; when the turtle looks around, quickly shine a mirror on it, and its urine will flow out. *Taiping Shenghui Fang* discusses infantile tortoise chest, attributing it to lung heat causing distension and fullness. If the nursing mother eats spicy foods, this symptom can also arise. If the nursing mother has retained milk fed to the infant, this disease may also result; frequently expressing the retained milk prevents this symptom. One should use *Gui Bei Wan* (Tortoise Back Pill) from *Shenghui Fang*. *Taiping Shenghui Fang* discusses tortoise back, stating that if an infant under one year old is forced to sit too early, exogenous wind invades the spine, causing the back to protrude like a tortoise shell. Moxibustion can treat this: moxa should be applied to Feishu (BL-13, Lung Shu) located 1.5 cun lateral to the lower border of the third thoracic vertebra, Xinshu (BL-15, Heart Shu) located 2.5 cun lateral to the lower border of the fifth thoracic vertebra, and Geshu (BL-17, Diaphragm Shu) located 1.5 cun lateral to the lower border of the seventh thoracic vertebra. Use 1 cun defined by the middle joint of the infant's finger. The moxa cone should be the size of a wheat grain. Stop after three to five moxa cones. There is also "Crane knee" syndrome, caused by insufficient congenital endowment and lack of Qi and Blood, resulting in thin muscles and exposed joints resembling crane knees. This is also due to Kidney deficiency. Qian Yi's *Dihuang Wan* (Rehmannia Pill) with added Lurong (Deer Antler) can tonify Kidney Qi. There is also delayed walking, caused by insufficient Qi and Blood failing to fill the bones with marrow, resulting in weakness and inability to walk. This is also due to deficiency of both Liver and Kidney. The Liver governs tendons; weak tendons fail to bind the joints. *Dihuang Wan* (Rehmannia Pill) with added Niuxi (Achyranthis Bidentatae Radix), Wujia Pi (Acanthopanacis Cortex), and Jiuzhi Lurong (Deer Antler prepared with wine) can be used. *Wujia Pi San* (Acanthopanacis Cortex Powder) is also effective. For tortoise chest, *Gui Xiong Wan* (Tortoise Chest Pill) disperses heat. *Songrui Dan* (Pine Pollen Pill) and *Baihe Dan* (Lily Bulb Pill) are particularly excellent for treating tortoise chest and tortoise back.

*Gui Xiong Wan* (Tortoise Chest Pill) treats infantile tortoise chest and tortoise back, caused gradually by lung heat and distension. Nursing mothers eating spicy foods can also cause this condition.
