According to *Chao Shi Bing Yuan* (Source of Diseases by Chao Yuanfang) regarding the condition of infants and children not growing teeth: Teeth are the culmination of bones, nourished by marrow. If an infant has insufficient congenital endowment, the marrow cannot fill the teeth and bones, thus causing a long delay in tooth eruption.

*Qianjin Yi Fang* (Supplement to the Thousand Golden Formulas) records: Bamboo or wood pieces soaked in urine are used to treat infants not growing teeth. Scrape these pieces on the first day of the New Year and apply them to the gums; teeth will grow immediately.

*Waitai Miyao* (Essential Prescriptions from the Imperial Library) cites another prescription from *Duan Ju*: Take three to seven feces of female mice. Rub one piece on the gum line until finished; teeth should erupt within twenty-one days. Female mouse feces are characterized by a pointed head. *Qianjin Fang* also adopts this method. *Yang Shi Chan Ru Fang* uses thirty pieces, specifying female mouse feces that are pill-shaped at both ends.

*Tai Ping Sheng Hui Fang* (Imperial Grace Formulas of the Taiping Era) for treating infants not growing teeth, or teeth failing to regrow after falling out:
Take two to seven black beans found in cow dung. Gently remove the skin from the tip of the bean. Use the opened end of this bean to apply to the gum line. Frequent use should be effective.

Zhang Huan stated: Those with insufficient congenital Kidney Qi have weak marrow. Since bones are the terminus of marrow, insufficient marrow cannot fill the teeth, resulting in delayed tooth eruption. The Xiang Fu Dan formula is suitable.
Da Xiang Fu Zi (Atractylodes Rhizoma, selected clean, peeled) Chen Xiang (Aquilaria Lignum Resinatum, each 1 liang) Bing Lang (Arecae Semen) Ci Shu Fen (Feces Mus Musculae Feminae, burnt to ash) Gan Chan (Bufo Viridis, burnt to ash. Each of the above 0.5 liang).
Pulverize the above ingredients and sieve into powder. Mix with 4 liang of sheep marrow, boiled until soft, to form pills the size of millet seeds. Administer ten pills per dose, washed down with Moschus decoction. Adjust dosage according to the child's age and size.

According to *Chao Shi Bing Yuan* regarding the condition of infants and children not growing hair: The Foot-Shaoyin meridian is the channel of the Kidney, and its flourishing manifests in the hair. If an infant has innate insufficiency leading to deficient Blood and Qi of the Shaoyin, the hair will be sparse, thin, or fail to grow. Some cases result from scalp sores causing alopecia; this is due to damage to the Blood, where diminished Blood and Qi fail to nourish the hair.

*Qianjin Fang* single-ingredient Qiu Ye formula for treating infants not growing hair on the head:

Once the ointment is ready, filter dregs and store in a copper vessel. Move it repeatedly to the north side of the eaves drip line, burying it under the seventh drip from the west end. After thirty days, the medicine is complete. For infants, shave the head and apply three times daily. For adults, wash the hair and apply; this is very effective.

*Ben Cao* states: Condensed steam water from steaming rice promotes hair growth. Collect this water while cooking rice and use it to wash the head to make hair long, dense, black, and shiny.
