立效散 耳内忽作大痛，如有虫在
内奔走，殊痛，或出血，或出水，或干痛，不可忍者。蛇退火烧存性，研末，鹅管吹
入立止。一方加冰片。（用蛇退者，取蛇之善脱以解郁火也。）
耳痛不可忍者 磨刀铁浆滴入耳中即愈。
又方 番大鳖子去壳，磨冰麝油，滴入耳中，自止。
《后汉·律历志》∶春分晷长七尺二寸四分，当至不至，多病耳痒。

声，始则快然，否则痒极欲死，此肾肝之火结成铁底于耳中，非汤药可救，宜救痒
丹主之。愈后服六味地黄丸三十斤可也。
耳痒，并治耳中有核，或耳屎凝结难取。胡桃肉煨热塞耳内，食顷即通。
耳痒或耳屎结于耳底，火酒滴入，片时即止。

Lixiao San (Instantly Effective Powder): Sudden severe pain in the ear, feeling as if insects are running inside, causing extreme pain, accompanied by bleeding, discharge of fluid, or dry pain that is unbearable. Burn snake slough to retain its medicinal properties (Charred Snake Slough), grind into powder, and blow into the ear using a goose quill; the pain stops immediately. Another prescription adds Borneol (Bingpian). (The use of snake slough is based on the principle that snakes shed their skin well, thereby resolving stagnant fire.)
For unbearable ear pain: Grind iron rust water (Iron Slurry) from a whetstone and drip it into the ear for immediate cure.
Another Prescription: Remove the shell of large soft-shelled turtle eggs, grind them mixed with borneol and musk oil, and drip into the ear; the pain will stop naturally.
*Book of Later Han · Treatise on Rhythms and Measures*: At the Spring Equinox, the gnomon shadow should be seven chi two cun four fen. If the shadow does not reach this length, people are prone to ear itching.
Master Qi stated: Some experience ear itching so intense that scratching with wood is insufficient to relieve it; one must pierce the bottom of the ear with an iron knife until it makes a clanging sound. Initially, this feels relieving; otherwise, the itch becomes so extreme one wishes to die. This is caused by kidney and liver fire condensing into a "iron base" within the ear, which cannot be cured by decoctions. It is appropriate to treat with Jiuyang Dan (Itch-Relieving Elixir). After recovery, taking thirty *jin* of Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) is advisable.
For ear itching, and also treating lumps in the ear or hardened earwax difficult to remove: Roast walnut kernel until hot and insert it into the ear; after the time it takes to eat a meal, the blockage will clear.
For ear itching or earwax condensed at the bottom of the ear: Drip Huojiu (Fire Wine/Spirits); it will stop in a moment.
Jiuyang Dan (Prescription by Master Qi)
Longgu (Fossilized Bones, 1 qian) Bingpian (Borneol, 3 fen) Zaocispina (Spine of Gleditsia Sinensis, 1 strip, burned to ash retaining properties)
First, grind the medicines finely. Take one gallbladder of a male rat, mix evenly with water, then add human milk and blend into a thick paste. Apply thoroughly into the ear canal. There will inevitably be unbearable itching; someone must hold the patient's hands. Once the itching subsides, self-healing occurs.
For redness and ulceration of the ear lobes: Pick tender branches of mulberry, jujube, locust, willow, and peach, boil in water to make a decoction, and wash three times daily.
Another Prescription: Grind Fritillariae Bulbus (Beimu) and Calomelas (Qingfen) uniformly and apply dry powder.
Feng Luzhan stated: Bleeding from the ear is caused by the stirring of fire in the Shaoyin channel. (*Jinnang*)
Li Dongyuan stated: Spontaneous bleeding from the ear is named Ernu (Auricular Epistaxis). It is caused by the counter-flow of ministerial fire from the liver and kidney, forcing blood to extravasate.
