The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: When a child's Kidney organ is vigorous and accompanied by Heat pathogen, the Heat rushes upward to the ear. The accumulation and coagulation of body fluids then generate pus. There are also cases where, due to bathing, water enters the ear and is not promptly drained, remaining stagnant. This stagnation interacts with blood and Qi, brewing into Heat, which also leads to the production of pus. These conditions are all referred to as Er Gan (Ear Fungus/Discharge). (If left untreated for a long time, it may develop into deafness.)
The *Jiyan Fang* (Collected Proven Prescriptions) states: Take the kernels from peach pits, cook them thoroughly, grind them into powder, (warm them), and use them to wrap and plug the ear. Frequent use yields good results.
The *Xiaoyan Fang* (Effective Prescriptions) states: Burn almond kernels and yellow rosin (beeswax), and use them to plug the ear.
Another prescription: Coptis Rhizome (Huanglian) and Alum (Fanshi), each two liang, are ground and sifted. Form into pills the size of a jujube pit, blow them into the ear, and the discharge will stop immediately.
The *Chan Jing* (Obstetrics Classic) states: Crush cinnamon twig powder, mix it with fish grease, and plug the ear. It will heal within three or four days.
Another prescription: Blow furnace bottom ash into the ear, pushing it deep inside. If there is no pain, it will naturally form a pellet and expel itself; this is effective.
The *Chan Jing* states: Pour vinegar into the ear, and the insects will come out.
Another prescription: Pour oil into the ear; this is effective.
Another prescription: Pour water into the ear (this is excellent).
Another prescription: Roast sesame seeds, wrap them in cotton, and plug the ear; the insects will come out.
Another prescription: Pour juice from peach leaves into the ear.
Another prescription: Use the hook of a leather belt to hook towards the ear canal; all insects will come out.
The *Chan Jing* states: Roast pig fat, add aromatic substances, and place it beside the ear canal; the insects will exit spontaneously; this is effective.
The *Chan Jing* states: Wrap salt in KT tree leaves and roast until hot. Apply this heat pack to the ear hole. Replace when cool, and the insects will come out.
The *Chan Jing* states: Stir-fry black sesame (Hu ma), store it in a kudzu cloth bag, and use it as a pillow. The insects, smelling the fragrance, will come out.
The *Luyan Fang* (Recorded Verified Prescriptions): Prescription for treating children whose eyes are blurred and cannot see objects:
Apply fish gallbladder to the eye. Carp gallbladder or crucian carp gallbladder are effective.
The *Chan Jing* states: Seven pieces of Coptis Rhizome (Huanglian) and one he (half unit) of human breast milk. Soak and apply externally. (Current note: The *Jiyao Fang* does not use human breast milk but divides the Huanglian into equal portions for use.)
Another prescription: Three he of bamboo sap juice and one he of human breast milk. Mix them, dip a piece of cotton in the mixture, and use it to wipe the eyes.
It also states: For children with red eyes and incessant tearing, moxa-heat the area with clustered hair on the big toe of the foot, known as the Dada point (SP2).
