属少阳相火。经云∶少阳之胜，耳痛。治以辛寒是也。生犀丸、犀角饮子、解热饮子。耳内痛生
疮，用黍粘子汤。耳湿肿痛，用凉膈散加酒炒大黄、黄芩、酒浸防风、荆芥、羌活服之，更以脑多麝
香少，湿加枯矾，吹入耳中。《丹铅续录》云∶王万里时患耳痛，魏文靖公劝以服青盐、鹿茸、煎雄、
附为剂，且言此药非为君虚损服之，
曷不观易之坎为耳痛，坎水藏，在肾开窍于耳，而水在志为恐，恐则伤肾，故为耳痛。气阳运动常显，
血阴流行常幽，血在形，如水在天地间，故坎为血卦，是经中已着病证矣，竟饵之而良愈。外治，白
龙散、杏仁膏、菖蒲挺子。或用穿山甲二片，土狗子二个，夹在穿山甲内，同炒焦，黑色为度，入麝
香少许同研细，吹一字于耳内。（亦治耳聋。）或用草乌削如枣核大，蘸姜汁塞耳内。（一方不用姜汁）。
或用郁金研细末，每以净水调一字，倾入耳，却急倾出。或用油胡桃肉为末，狗胆汁和为丸，如桐子
大，绵裹安耳中。或用食盐炒热，用枣面蒸熟，青花布包定枕之。
沈存中云∶予为河北察访使时，病赤目四十余日，黑睛傍黯赤成疮，昼夜痛楚，百疗不瘥。郎官
丘革相见问予，病目如此曾耳中痒否，若耳中痒，即是肾家风，有四生散疗肾风，每作二、三服即瘥。
闾里号为圣散子。予传其方合服之，午时一服，临卧一服，目反大痛，至二鼓时乃能眠，及觉目赤稍
散，不复痛矣，更进三四服，遂平安如常。是时孙和甫学士帅镇阳，闻予说大喜曰，吾知所以自治目
矣。向久病目，尝见吕吉甫参政云顷，目病久不瘥，因服透冰丹乃瘥，如其言修合透冰丹一剂，
试服了二三十服，目遂愈。乃知透冰丹亦疗肾风耳。《圣惠》云∶有人耳痒，一日一作可畏，直挑剔
出血稍愈，此乃肾脏虚，致浮毒上攻，未易以常法治也，宜服透冰丹。勿饮酒、啖湿面、菜蔬、鸡、
猪之属，能尽一月为佳，不能戒无效。
Belongs to Shaoyang Ministerial Fire (Shàoyáng Xiànghuǒ). The classics state: "When Shaoyang Ministerial Fire prevails, there is ear pain." Treatment should employ acrid-cold substances. Formulas such as Shengxi Wan (Raw Rhinoceros Horn Pill), Xijiao Yinzi (Rhinoceros Horn Decoction), and Jiierer Yinzi (Heat-Resolving Decoction) may be used. If there is pain and ulceration within the ear, use Shunianzi Tang (Arctii Fructus Decoction). For dampness, swelling, and pain in the ear, administer Liangge San (Cooling the Diaphragm Powder) with Da Huang (Rhubarb Root and Rhizome) stir-fried with wine, Huangqin (Scutellaria Root), Fangfeng (Saposhnikovia Root) soaked in wine, Jingjie (Schizonepeta Spike), and Qianghuo (Notopterygium Rhizome and Root). Additionally, apply a mixture of more Borneolum Syntheticum (Bingpian, 冰片) and less Moschus (Shexiang, 麝香); if dampness is heavy, add Calcitum (Gufan, 枯矾), and insufflate into the ear. *Danqian Xulu* records: Wang Wanli suffered from ear pain at that time. Wei Wenjing advised him to take Qingyan (Green Salt), Lurong (Deer Antler without Bone), Xionghuang (Realgar), and Fuzi (Aconite Lateralis Radix Praeparata) decocted into a pill. He stated that these medicines were not taken for the sovereign's deficiency, but asked why one did not consult the *I Ching*: Kan (Water) corresponds to ear pain. Kan represents Water; the Kidney stores essence and opens into the ears. In emotions, Water corresponds to Fear; fear injures the Kidney, thus causing ear pain. Qi, being Yang, moves and manifests constantly; Blood, being Yin, circulates and remains hidden. Blood resides in the form, just as water exists between heaven and earth; therefore, Kan is the hexagram of Blood. This pathology is already documented in the meridians. Ultimately, he took the medicine and recovered well. External treatments include Bailong San (White Dragon Powder), Xingren Gao (Apricot Seed Ointment), and Changpu Tingzi (Acorus Stick). Alternatively, use two pieces of Pangolin Scales (Chanshunjia, 穿山甲) and two ground beetles (Tougouzi, 土狗子), sandwich them together, and stir-fry until scorched black. Add a small amount of Moschus (Shexiang, 麝香), grind finely, and insufflate an amount equivalent to one character (a traditional measure) into the ear. (This also treats deafness.) Alternatively, carve Aconiti Kusnezoffii Radix (Caowu, 草乌) into the size of a jujube pit, dip it in ginger juice, and insert it into the ear. (Another method does not use ginger juice.) Alternatively, grind Curcumae Zedoariae Rhizoma (Yujin, 郁金) into fine powder. Each time, mix one character's worth with clean water, pour into the ear, and immediately tilt it out. Alternatively, use oil walnut kernel powder mixed with Dog Gallbladder (Goudan, 狗胆汁) to form pills the size of paulownia seeds, wrap in cotton, and place in the ear. Alternatively, stir-fry common salt until hot, steam it with jujube paste, wrap in blue-and-white porcelain-patterned cloth, and use as a pillow.
Shen Kuo said: When I served as the Inspector of Hebei, I suffered from red eyes for over forty days. The area beside the cornea became dark red and formed ulcers, causing day and night pain, which resisted all treatments. Official Qiu Ge asked me, "With your eyes in this condition, do you have itching in your ears? If your ears itch, it is 'Kidney Wind' (Shenfeng, 肾风). Si Sheng San (Four Raw Substances Powder) treats Kidney Wind. Taking two or three doses usually cures it. It is known among the people as Sheng Sanzi (Holy Particle Powder)." I transmitted his formula and took it combined with my own regimen. One dose at noon, one dose before bed. My eyes suddenly hurt severely, and I could only sleep after the second watch. Upon waking, the redness had dispersed slightly, and the pain ceased. After taking three or four more doses, I returned to normal health. At that time, Academician Sun Hefu was governing Zhenyang. Hearing my account, he rejoiced greatly, saying, "Now I know how to treat my eye disease myself." Previously, when suffering from chronic eye disease, I heard Censor Lü Jifu say that his long-standing eye ailment was cured by taking Toubing Dan (Ice-Penetrating Pill). Following his advice, I prepared one batch of Toubing Dan (Ice-Penetrating Pill) and took twenty or thirty doses, after which my eyes healed. Thus, I realized that Toubing Dan (Ice-Penetrating Pill) also treats Kidney Wind (Shenfeng, 肾风). *Taiping Shenghui Fang* records: Someone suffered from ear itching, occurring once a day, which was terrifying. Only after picking until bleeding did it improve slightly. This is due to Kidney deficiency causing floating toxins to attack upward, which is difficult to treat with conventional methods. It is appropriate to take Toubing Dan (Ice-Penetrating Pill). Avoid alcohol, wet noodles, vegetables, chicken, pork, etc. Adhering to this diet for a month is ideal; failure to abstain renders the treatment ineffective.
