牙痛者，足阳明之病也。阳明主降，降者浊气不至上壅，是以不痛。若胃逆不降，浊气壅迫，甲木逆
冲，攻突牙床，是以肿疼。相火上炎，是以热生。甲木郁于湿土之中，腐败蠢朽，是以虫生，而齿坏也。
如牙疼龈肿者，以黄芩石膏汤主之。如虫牙，以柴胡桃仁汤主之。
黄芩石膏汤
黄芩（三钱） 石膏（三钱） 甘草（二钱） 半夏（三钱） 升麻（二钱） 芍药（三钱）
水煎大半杯，热服，徐咽。
柴胡桃仁汤
柴胡（三钱） 桃仁（三钱） 石膏（三钱） 骨碎补（三钱） 水煎半杯，热服，徐咽。
咽喉者，阴阳升降之路也。咽为六腑之通衢，喉为五脏之总门。六腑为阳，阳中有阴。浊阴由咽
而下达，是天气之降也。五脏为阴，阴中有阳。清阳自喉而上腾，是地气之升也。地气不升则喉病，喉病
者，气塞而食通。天气不降则咽病，咽病者气通而食塞。先食阻而后气梗者，是脏完而腑伤之也。先气梗
而后食阻者，是腑完而脏伤之也。而总之咽通六腑，而胃为之主。喉通五脏，而肺为之宗。如阳衰土
湿，肺胃不降，浊气湮郁，则痹塞之病成矣。相火升炎，则肿痛之病作矣。如咽喉肿痛生疮者，以甘草桔梗射
干汤主之。如喉疮脓成者，以贝母升麻鳖甲汤主之。
甘草桔梗射干汤
甘草（二钱生） 枯梗（三钱） 半夏（三钱） 射干（三钱） 水煎半杯，热漱，徐服。
贝母升麻鳖甲汤

Toothache is a disease of the Foot-Yangming (Stomach) channel. The Yangming channel governs descending; when descending functions normally, turbid qi does not obstruct upward, thus there is no pain. If stomach qi rebels and fails to descend, turbid qi becomes stagnant and oppressive, causing Jia Wood (Gallbladder Qi) to rebel and rush upward, attacking the dental alveolus, resulting in swelling and pain. Ministerial Fire flares upward, generating heat. When Jia Wood is depressed within damp Earth, it rots and decays, leading to the generation of "worms" (caries) and tooth destruction. For toothache accompanied by gingival swelling, Huangqin Shigao Tang (Scutellaria and Gypsum Decoction) is prescribed. For dental caries ("worm teeth"), Chaihu Taoren Tang (Bupleurum and Peach Kernel Decoction) is prescribed.

Huangqin (Scutellariae Radix, 3 qian), Shigao (Gypsum Fibrosum, 3 qian), Gancao (Glycyrrhizae Radix et Rhizoma, 2 qian), Banxia (Pinelliae Rhizoma, 3 qian), Shengma (Cimicifugae Rhizoma, 2 qian), Shaoyao (Paeoniae Radix, 3 qian).
Decoct with water to obtain slightly more than half a cup, take hot, and swallow slowly.
Chaihu Taoren Tang (Bupleurum and Peach Kernel Decoction)
Chaihu (Bupleuri Radix, 3 qian), Taoren (Persicae Semen, 3 qian), Shigao (Gypsum Fibrosum, 3 qian), Gusuibu (Drynariae Rhizoma, 3 qian).
Decoct with water to obtain half a cup, take hot, and swallow slowly.
The throat and pharynx are the pathways for the ascending and descending of Yin and Yang. The pharynx (Yan) is the thoroughfare of the Six Fu Organs, while the larynx/pharynx proper (Hou) is the main gate of the Five Zang Organs. The Six Fu Organs belong to Yang, containing Yin within Yang. Turbid Yin descends through the pharynx, representing the descent of Heaven Qi. The Five Zang Organs belong to Yin, containing Yang within Yin. Clear Yang ascends from the Hou, representing the ascent of Earth Qi. If Earth Qi fails to ascend, Hou diseases occur, characterized by Qi obstruction but food passage remaining open. If Heaven Qi fails to descend, Yan diseases occur, characterized by Qi passage remaining open but food obstruction. If food obstruction precedes Qi blockage, it indicates intact Zang organs but injured Fu organs. If Qi blockage precedes food obstruction, it indicates intact Fu organs but injured Zang organs. In summary, the Yan connects to the Six Fu Organs, with the Stomach as its master; the Hou connects to the Five Zang Organs, with the Lung as its patriarch. If Yang Qi declines and Spleen Earth is damp, causing Lung and Stomach Qi to fail to descend, turbid Qi becomes stagnant and congested, forming Bi obstruction diseases. If Ministerial Fire rises and inflames, swelling and pain diseases arise. For sore throat and pharyngitis with swelling, redness, and ulceration, Gancao Jiegeng Yegan Tang (Licorice, Platycodon, and Belamcanda Decoction) is prescribed. For Hou ulcers where pus has formed, Beimu Shengma Biejia Tang (Fritillaria, Cimicifuga, and Turtle Shell Decoction) is prescribed.
