经曰∶中央黄色，入通于脾，开窍于口。又曰∶脾气通于口，脾和口能知五味矣。故口者脾之外候。凡鹅口
者，口内白屑满舌，如鹅之口。此肺热而心脾为甚，故发于口也。内服沆瀣丹，外以保命散吹之。
口疮者，满口赤烂。此因胎禀本浓，养育过温，心脾积热，熏蒸于上，以成口疮。内服沆瀣丹，外以地鸡擂
水搽疮上。地鸡即扁虫，人家HT 下有之。
口糜者，满口生疮溃烂，乃膀胱移热于
小肠，膈肠不便，上为口糜。以导赤散去小肠之热，五苓散去膀胱之热，当以二方合服。
口疮服凉药不效，乃肝脾之气不足，虚火泛上而无制。宜理中汤收其浮游之火，外以上桂末吹之。若吐泻后口
中生疮，亦是虚火，理中汤。昧者以为口疮悉为实热，概用寒凉，必不救。
上 有胀起如悬痈者，此名重 。由脾胃挟热，气血不能收敛而成。用针刺去恶血，内服沆瀣丹，外以碧雪吹之。
小儿两颐流涎，浸渍胸前者，此名滞颐。盖涎者脾之液，口为脾窍，脾胃虚寒，不能收敛津液，故涎从口出
而滞于颐，宜温脾丹。
小儿口频撮者，气不和也。盖唇应乎脾，气出于肺，脾虚不能生肺，故口频撮。异功散补脾生肺愈矣。
小儿口撮，面青多哭，此阴寒之至，肝脾虚冷，脐下痛也。理中汤温之。
小儿急欲吮乳而口不能吮者，心脾有热，舌不转运。泻黄散清之。
鼻部疳疮溃烂，使用杏仁去皮和尖端，用纸张包裹压榨去除油脂，直到变成白色粉末为止。每取杏仁粉二分，配合真轻粉一钱，混合均匀后吹敷患处。
鼻腔流出浑浊鼻涕不止，称为鼻渊。这是由于风热邪气侵袭脑部所致。使用炒苍耳子、辛夷仁、白芷、薄荷各等分，研成细末。每次服用一钱，临睡前用葱汤调服，不拘次数，以痊愈为标准。
鼻腔流出臭秽黄水，称为控脑沙。使用紫贝子（俗名南蛇牙齿，广东人称为狗屐螺），取二三枚，用火煅烧后用醋淬炼成粉末，用纸包好放置在地上以去除火毒。每次服用一钱，成人服用二钱，用丝瓜藤煎汤送服药粉，空腹服用，以痊愈为标准。
鼻子受到外伤破损，或擦脱落，立即剪碎猫头上的毛，用口中津液调和后敷贴患处，可自行愈合。
疳疮侵蚀鼻部，破烂不堪。使用五倍子烧成灰但保留药性，研成粉末，用腊月猪油调和涂抹患处。
《内经》说：中央黄色，通应于脾，开窍于口。又说：脾气通达于口，脾功能正常则口能辨别五味。所以口是脾的外在表现。凡是鹅口疮，口腔内满布白屑覆盖舌面，像鹅的嘴巴一样。这是因为肺热且心脾热盛，所以发于口部。内服沆瀣丹，外用保命散吹敷患处。
口疮，满口红肿糜烂。这是因为先天禀赋浓厚，养育环境过热，导致心脾积热，热气熏蒸上部，形成口疮。内服沆瀣丹，外用扁虫（地鸡）研磨的水搽涂疮面。扁虫即蛞蝓，人家屋檐下常见。
口糜，满口生疮溃烂，这是膀胱的热邪移注于小肠，导致膈部和肠道气机不畅，热气上逆形成口糜。使用导赤散清除小肠之热，五苓散清除膀胱之热，应当将两方合用服用。
口疮服用凉药无效，这是肝脾之气不足，虚火上炎而无制约。宜用理中汤收敛浮游之火，外用上桂末吹敷患处。若在吐泻之后口中生疮，也是虚火所致，使用理中汤。愚昧之人认为口疮全是实热，一概使用寒凉药物，必然无法治愈。
上颚有肿胀突起如悬痈者，此名重龈。这是由于脾胃挟带热邪，气血不能收敛而成。用针刺放出恶血，内服沆瀣丹，外用碧雪吹敷患处。
小儿两侧面颊流涎，浸渍胸前的，此名滞颐。涎液是脾的体液，口为脾之窍，脾胃虚寒，不能收敛津液，所以涎液从口流出而停滞于面颊，宜用温脾丹。
小儿频繁撮动嘴唇，是气机不和。唇对应脾，气出于肺，脾虚不能滋养肺，所以口频繁撮动。异功散补脾生肺即可痊愈。
Nasal ganoderma ulceration: Use almonds, removing the skin and tips. Wrap in paper and press to remove oil until it becomes a white powder. Mix two fen of almond powder with one qian of genuine calomel (mercurous chloride), blend evenly, and insufflate onto the affected area.
Continuous discharge of turbid nasal mucus is called Bi Yuan (nasal sinusitis). This is caused by wind-heat invading the brain. Use equal parts of stir-fried Xuanxiaozi (Cocklebur Fruit), Xinyiren (Magnolia Flower Bud), Baizhi (Angelica Dahurica Root), and Bohe (Mint Leaf). Grind into fine powder. Take one qian each time, mixed with scallion decoction before bedtime. Do not limit the number of doses; continue until healed.
Discharge of foul-smelling yellow fluid from the nose is called Kong Nao Sha. Use Zibeizi (Purple Cowrie Shell, commonly known as Nan She Ya Chi or Gou Ji Luo). Take two or three shells, calcine over fire, quench in vinegar, and grind into powder. Wrap in paper and place on the ground to remove fire toxicity. Take one qian per dose (two qian for adults), mixed with Si Gua Teng (Luffa Vine) decoction. Take on an empty stomach until healed.
For traumatic injury or abrasion of the nose: Immediately cut up hair from a cat's head, mix with saliva, apply topically, and it will heal spontaneously.
Gan sores eroding the nose causing severe ulceration: Burn Wu Beizi (Galla Chinensis) to ash while retaining its properties, grind into powder, and mix with lard (from pigs slaughtered in the twelfth lunar month) for topical application.
The Classic states: "The central color is yellow, connecting to the Spleen, opening into the mouth." It also says: "Spleen Qi communicates with the mouth; when the Spleen is harmonious, the mouth can perceive the five flavors." Thus, the mouth is the external manifestation of the Spleen. E Kou (Goose Mouth) refers to white patches covering the tongue and oral cavity, resembling a goose's beak. This is due to Lung heat exacerbated by Heart and Spleen heat, manifesting in the mouth. Internally administer Hangxie Dan; externally insufflate Baoming San.
Kou Chuang (Oral Ulcers) involves redness and erosion throughout the mouth. This results from strong congenital constitution, excessive warmth in upbringing, leading to accumulated heat in the Heart and Spleen steaming upwards. Internally administer Hangxie Dan; externally apply water-ground Di Ji (Agriolimax agrestis/Slug) to the ulcers. Di Ji is found under eaves.
Kou Mi (Oral Thrush/Mucositis) involves widespread ulceration in the mouth. This occurs when Heat transfers from the Bladder to the Small Intestine, causing stagnation in the diaphragm and intestines, with heat rising to form oral mucositis. Use Dao Chi San to clear Small Intestine heat and Wu Ling San to clear Bladder heat; combine both formulas for administration.
If oral ulcers do not respond to cooling herbs, it indicates deficiency of Liver and Spleen Qi with uncontrolled floating deficient fire. Use Lizhong Tang to anchor the floating fire; externally insufflate Shang Gui (Cinnamon Bark) powder. If ulcers appear after vomiting or diarrhea, it is also due to deficient fire; use Lizhong Tang. Ignorant practitioners assume all oral ulcers are excess heat and indiscriminately use cold herbs, which inevitably fails to cure.
Swelling on the upper palate resembling a suspended abscess is called Chong Yin. This is caused by Spleen and Stomach heat preventing Qi and Blood from consolidating. Prick with needles to release bad blood; internally administer Hangxie Dan; externally insufflate Bi Xue.
Saliva flowing from the cheeks of infants, soaking the chest, is called Zhi Yi. Saliva is the fluid of the Spleen, and the mouth is the orifice of the Spleen. Due to Spleen-Stomach deficiency-cold failing to consolidate fluids, saliva flows out and stagnates on the cheeks. Use Wen Pi Dan.
Frequent puckering of the lips in infants indicates disharmony of Qi. The lips correspond to the Spleen, and Qi originates from the Lung. Spleen deficiency fails to generate Lung Qi, causing lip puckering. Use Yigong San to tonify the Spleen and generate Lung Qi to cure.
Infants with puckered lips, cyanotic complexion, frequent crying, indicate extreme Yin-cold, Liver-Spleen deficiency-cold, and pain below the umbilicus. Warm with Lizhong Tang.
Infants eager to suckle but unable to do so have Heat in the Heart and Spleen, causing immobility of the tongue. Clear with Xie Huang San.
