Diao Yuan San: Treats congenital insufficiency, resulting in the separation of the cranial fontanelles (failure of the infant's skull sutures to close), emaciation, and delayed development of teeth, speech, and walking.
Shan Yao (Chinese Yam Rhizome) (1 qian), Bai Fu Shen (Poria with Hostwood), Ren Shen (Ginseng Root), Bai Fu Ling (Poria), Huang Qi (Astragalus Root, honey-fried), Shu Di Huang (Prepared Rehmannia Root), Bai Zhu (Atractylodes Macrocephala Rhizome), Bai Shao Yao (White Peony Root) (each 5 fen);
Chuan Xiong (Ligusticum Chuanxiong Rhizome), Zhi Gan Cao (Honey-fried Licorice Root) (each 6 fen); Shi Chang Pu (Acorus Tatarinowii Rhizome) (4 fen). Decoct with fresh ginger and Chinese jujube.

Ren Shen Di Huang Wan: For infants with separated cranial fontanelles, this is due to incomplete Kidney Qi. The Kidneys govern bone marrow, and the brain is the sea of marrow. Incomplete Kidney Qi leads to insufficient brain marrow, hence the failure of closure.
Ren Shen (Ginseng Root) (2 qian), Shu Di (Prepared Rehmannia Root) (4 qian), Lu Rong (Deer Antler Velvet, baked in wine), Huai Shan Yao (Chinese Yam Rhizome), Bai Fu Ling (Poria), Shan Yu Rou (Cornus Officinalis Fruit, pitted), Mu Dan Pi (Moutan Cortex) (each 3 qian).
Grind into powder, form pills with honey the size of Euryale Seed. Dissolve and take with Ginseng decoction, taken after meals; it yields miraculous effects.

Treatment for Separated Fontanelles (from Zhuang Shi):
Shan Yin Chen (Artemisia Capillaris Herb), Bai He (Lily Bulb), Che Qian Zi (Plantago Seed) (each 5 qian).
Grind into powder, mix with black cow's milk, apply to both soles and the open cranial sutures, wrap with cloth, change once every three days.

Method to Seal the Fontanelle: Donkey head bones, any quantity, burn to ash and grind finely, mix with refined sesame oil, and apply to the cranial sutures.
Another method: Roast dog head bones until yellow, grind into powder, mix with egg white, and apply.

He Che Di Huang Wan:
Zi He Che (Human Placenta) (one piece), Shu Di (Prepared Rehmannia Root, mashed into paste, 8 liang), Huai Shan Yao (Chinese Yam Rhizome, stir-fried, 4 liang), Dan Pi (Moutan Cortex), Bai Fu Ling (Poria), Ze Xie (Alisma Rhizome, salt-water fried) (each 3 liang);
Shan Yu Rou (Cornus Officinalis Fruit, pitted, wine-fried, 4 liang).
Grind all ingredients into powder, make pills with refined honey the size of Euryale Seed. Take one pill each morning and evening with warm water. If the fontanelle does not close or scalp sores do not dry, apply ash from old turtle shell externally.

Chen Shigong stated: "Shan Gong Tou" (Leech-arched head), commonly known as "Nao Zhu" (Brain Pig). Afflicting young children but rooted in deep congenital factors, this arises from toxic accumulation in the father's essence and mother's blood. After birth, exposure to toxins causes only one episode; the lesion swells high, breaks out, and swells again. This is because during conception, there was originally a membrane wrapping the toxin; although the toxin exits, the membrane remains, causing recurrence after healing. When pus matures and swelling is severe, puncture with a needle. If wind attacks the external wound, and although it does not swell, it fails to heal, use Bai Tong San (Defective Copper Powder) as the main treatment. (*Waike Zhengzong*)
Gu Shicheng stated: There are also cases where infants sleep at night with their heads hidden in the wet nurse's embrace, formed by heat steaming. There are also cases caused by infants failing to avoid intense sunlight and summer toxicity. At the initial stage, apply licorice paste externally, and it will subside spontaneously; if fully formed, encircle the base of each lesion individually to prevent spreading and difficulty in drying, which is an unchangeable method.
He further stated: After recovering from Shan Gong Tou, one must abstain from eating leeches, otherwise, it will recur the following year.
*Xin Fa* states: Shan Gong Tou is also known as Lou Gu Ji (Mole Cricket Boil), commonly known as He Qi.
