验案
一人喉痛、痔痛，六脉沉迟，此胃气不充，水不济火也。盖釜底之火不生，则脾不运，
而水源不旺，不旺则寒而虚火起矣，故有喉痛等证而脉迟也。必须温其釜底，则水暖而上升，津
液得润而浮游之火自平，诸证可安也。故六味不如八味，再加起脾之药自愈。大凡补药，不
论上、中、下证，必先以起脾为要；脾为后天生生之本，本立则诸病自退。况病在肾，不先
于脾胃着意，纵有生水之功，而无防水之法，则效不捷矣。
牙根腐烂，并非胃火所致，而是因为肾水不足，导致太阳膀胱经的火邪横行，并与心火相互结合而炽盛，治疗需用泻心汤进行加减。
凡是因阴虚导致虚火上炎引起的上齿疼痛，可用四物汤合升麻葛根汤治疗。

牙根肿胀，嘴巴难以张开，将巴豆捣碎取油涂在草纸上，把草纸捻成条状，点燃后吹熄，用产生的烟熏鼻子即可使嘴张开；或者用朴硝一钱八分，蒲黄屑四分，僵蚕二分，牙皂一分，冰片一分，共同研成细末吹入鼻腔。
吐血之后出现气逆、喉咙痛，以茯苓补心汤为主治方剂。

配方：人中白（一钱）、硼砂（五分）、胆矾（三分）、冰片（一分），共同研成细末吹入咽喉。
实热导致口腔内生疮，伴有烦躁口渴、脸颊疼痛。用藿香七钱，石膏、栀子、炙甘草各五钱，防风四钱，共同研成细末。
大肠脉象实大导致的口疮，用生姜、陈皮、竹茹、黄芩、栀子、白术各五钱，桂心一钱，茯苓、芒硝、生首乌头末二钱，砂仁头末一钱五分，制成蜜丸含化。
医案
有一人喉咙痛、痔疮痛，六脉沉迟，这是胃气不充实，肾水不能制约心火的表现。大概就像锅底的火不生，脾脏就不能运化，水源就不旺盛；水源不旺盛则产生寒象，进而引发虚火，所以会出现喉咙痛等症状而脉象迟缓。必须温补锅底（脾胃），这样水暖而上升，津液得到滋润，浮游的虚火自然平息，各种症状就可以安定。因此，六味地黄丸不如八味地黄丸，再加健脾的药物就能自愈。大凡使用补药，不论病证在上、中、下哪一部，都必须先以恢复脾胃功能为关键；脾胃是后天生生不息的根本，根本确立则各种疾病自然消退。况且病位在肾，如果不先在脾胃上下功夫，即使有滋补肾水的功效，也没有防止水湿泛滥的方法，那么疗效就不会迅速。
The rotting of the gum roots is not caused by Stomach Fire, but due to insufficiency of Kidney Water, leading to rampant Fire of the Taiyang Bladder channel, which combines with Heart Fire to become excessive. Treatment requires modification of Xiexin Tang (Drain the Epigastrium Decoction).
For upper toothache caused by Yin deficiency and rising deficient fire, Siwu Tang (Four Substances Decoction) combined with Shengma Gegen Tang (Kudzu and Rhizoma Cimicifugae Decoction) should be used.
If the tongue protrudes about one cun, applying Bingpian (Borneolum Syntheticum) will cause it to retract immediately.
For adults and children with swelling under the tongue, known as Chongshe (Double Tongue), accompanied by surging phlegm and difficulty speaking, mix Pengsha (Borax), Zhusha (Cinnabar), and Puxiao (Mirabilite) each at 5 fen, and Bingpian (Borneolum Syntheticum) at 1 fen into a powder. Mix with honey and apply externally.
For swollen gum roots and inability to open the mouth, press Badou (Fructus Crotonis Tiglii) to extract oil, soak it in grass paper, roll the paper into a strip, ignite it, blow out the flame, and use the smoke to fumigate the nose to restore mouth opening; alternatively, use Puxiao (Mirabilite) 1 qian 8 fen, Puhuang (Pollen Typhae) 4 fen, Jiangcan (Bombyx Batryticatus) 2 fen, Yazao (Gleditsia Sinensis Fruit) 1 fen, and Bingpian (Borneolum Syntheticum) 1 fen, grind into a fine powder, and insufflate into the nose.
After hematemesis, if there is rebellious Qi and sore throat, Fuling Buxin Tang (Poria Cocos Tonifying the Heart Decoction) is the primary treatment.
For Hou'e (Throat Moth/Epiglottitis-like lesions) in the throat, with surging phlegm and sore throat, use Danfan (Alumen) 3 fen and Pengsha (Borax) 2 fen, mixed with boiling water for oral administration, and use external insufflation.
Formula: Renzhongbai (Calcinata Humanis Ossis or similar calcined substance) 1 qian, Pengsha (Borax) 5 fen, Danfan (Alumen) 3 fen, Bingpian (Borneolum Syntheticum) 1 fen. Grind into powder and insufflate.
For mouth ulcers caused by Excess Heat, accompanied by irritability, thirst, and cheek pain, use Huoxiang (Patchouli Herba) 7 qian, Shigao (Gypsum Fibrosum), Zhizi (Gardeniae Fructus), and Zhi Gancao (Prepared Licorice Root) each 5 qian, and Fangfeng (Saposhnikoviae Radix) 4 qian. Grind into powder.
For mouth ulcers associated with an Excess pulse in the Large Intestine channel, use Shengjiang (Zingiberis Rhizoma Recens), Chenpi (Citri Reticulatae Pericarpium), Zhuru (Bambusae Caulis in Taenia), Huangqin (Scutellariae Radix), Zhizi (Gardeniae Fructus), and Baizhu (Atractylodis Macrocephalae Rhizoma) each 5 qian, Guixin (Cinnamomi Cortex) 1 qian, Fuling (Poria), Mangxiao (Natrii Sulfas), Sheng Toumo (Head Powder of Raw Polygonum Multiflorum) 2 qian, and Sharen Toumo (Head Powder of Amomi Fructus) 1 qian 5 fen. Form into honey pills and hold in the mouth to dissolve.
Medical Case
A patient presented with sore throat and hemorrhoid pain, with deep and slow pulses in all six positions. This indicates insufficient Stomach Qi and Kidney Water failing to control Fire. Just as fire not being lit at the bottom of the pot leads to spleen dysfunction and weak water source, weakness leads to cold and rising deficient fire, hence symptoms like sore throat with a slow pulse. It is necessary to warm the "bottom of the pot" (Spleen/Stomach), so that water warms and rises, fluids are moistened, and floating deficient fire naturally calms, resolving the symptoms. Therefore, Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) is inferior to Shenqi Dihuang Wan (Eight-Ingredient Pill with Rehmannia), especially when combined with herbs that strengthen the Spleen. Generally, when using tonics, regardless of whether the pathology is in the Upper, Middle, or Lower Jiao, restoring Spleen function must be prioritized. The Spleen is the root of postnatal generation; once the root is established, diseases recede naturally. Moreover, since the disease is located in the Kidney, if no attention is paid to the Spleen and Stomach first, even if there is efficacy in generating Water, there is no method to prevent water overflow, resulting in delayed therapeutic effects.
