According to *Zhu Bing Yuan Hou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) regarding the condition of pediatric "Moon Eclipse Sores" (Ulcers appearing in infants, believed to correlate with lunar phases): Ulcers appear around the ears, nose, and mouth of children. The world calls this "Moon Eclipse Sore," as it rises and falls with the moon, hence the name. Folklore states: If a child points at the newly born moon with their finger, it causes ulcers to grow under the ear, thus named "Moon Eclipse Sore."

*Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) discusses: During solar or lunar eclipses, one must avoid eating and drinking. Violating this taboo leads to intestinal parasites and incomplete development of offspring conceived during intercourse; one will inevitably suffer from Moon Eclipse Sores. One must also not breastfeed the infant until the sun and moon return to normal. Symptoms such as bad breath, broken teeth, receding gums with frequent bleeding, and ulcers on the tongue are all caused by violating this taboo. It is necessary to perform the "Rescue the Moon" ritual during an eclipse; failing to do so and going out into a rainstorm brings disaster. The staff used for rescuing the moon must be collected, and divine medicines for treatment should be prepared in advance to administer to those suffering from this condition.

*Tai Ping Sheng Hui Fang* (Imperial Grace Formulary of the Taiping Era) discusses Moon Eclipse Sores: These sores arise between the two ears and the nose/face, as well as on the sides of various lower orifices. They erode deeply, reaching bone and muscle. The sores peak at the beginning of the lunar month and wane at the end, changing with the moon's phases, hence the name. Additionally, ulcers growing under a child's ear are also called Moon Eclipse Sores. Folklore claims that pointing at the moon causes this disease. If sores develop within various orifices, it indicates the presence of parasites; if untreated for a long time, they transform into malignant conditions.

*Ge Shi Zhou Hou Fang* (Emergency Prescriptions Kept at the Elbow of Ge Hong) records that early-stage pediatric Moon Eclipse Sores mostly occur in the two ears and seven orifices (eyes, ears, mouth, nose), rising and falling with the moon. Common belief attributes this to children pointing at the moon. Formula: Burn earthworm feces until red, mix with ointment/fat, and apply. *Qianjin Fang* suggests mixing with pig fat.

Another formula from *Ge Shi Zhou Hou Fang*: Use toad powder collected in May, mixed with ointment/fat for application. *Wai Tai Mi Yao* (Prescriptions from the Imperial Library) suggests using pig fat.

*Qianjin Fang* formula for treating pediatric Moon Eclipse Sores, varying with the moon: Mix lead white (Hu Fen) with butter/suet and apply. Cures in five days.

*Qianjin Fang* formula for Moon Eclipse Sores affecting all nine orifices: Mix rice flour with water and apply.

*Qianjin Fang* formula for treating malignant Moon Eclipse Sores with necrotic flesh: Sulfur (Liu Huang), Ru Cao (a type of herb), and Mylabris (Ban Mao) in equal parts. (*Sheng Hui Fang* specifies half liang each of Liu Huang and Ru Cao, and one fen of Ban Mao. Roast Ban Mao with glutinous rice until slightly yellow, remove legs and wings.) Grind the three ingredients into powder. Apply to the sore; if dry, reapply mixed with pig fat, three times daily and once at night.

Another *Qianjin Fang* formula: Evodia root (Wu Zhu Yu Gen), Rose root (Qiang Wei Gen), and Sanguisorba root (Di Yu Gen) in equal parts (3 liang each). Grind into powder. Wash the sore with salt water before applying, three times daily. (*Sheng Hui Fang* uses half liang per dose, added to warm water for washing.)

*Wai Tai Mi Yao* citing *Ji Yan Fang* for curing pediatric head sores, Moon Eclipse Sores, perioral fatty sores, and snail sores: Huang Lian Hu Fen Ointment. Coptis chinensis (Huang Lian, 2 liang), Lead White (Hu Fen), and Mercury (Shui Yin, ground in; each 1 liang). Grind the three ingredients into powder. Mix with water and grind with mercury until uniform. Apply to sores. Even if yellow fluid flows forming a new sore, dusting with powder cures it. Another version adds calcined Alum (Bai Fan, 1 liang) and Cnidium seed (She Chuang Zi, 1 liang, powdered); this is also excellent. Apply from the ear to the neck.

*Tai Ping Sheng Hui Fang* formula for pediatric Moon Eclipse Sores on the upper ears with continuous pus discharge, recommending Mercury Ointment: Mercury (Shui Yin), Coptis chinensis (Huang Lian, heads removed, powdered; each 2 liang), Pine Rosin (Song Zhi), and Lead White (Hu Fen, mixed with a little water and ground with mercury until mercury stars disappear; each 1 liang). Grind all ingredients evenly in a mortar. Dust powder onto sores. If sores are dry, use refined pig fat to make a paste. Before each application, wash sores clean with salt water, dry, then apply.
