二金散（《启玄》）
鸡内金 郁金
各等分研细，先用盐汤洗净，吹之。
呵欠者，脾胃中气不足，精神劳倦所致也。经曰∶足阳明之脉，是动则病振寒，
善伸数欠，欠者阳引而上，阴引而下，乃精与神不相根据，而阴与阳不相守也。
舌为心苗，应南方火。邪在表，则未生苔；邪入里，津液搏结，则生苔而滑。苔
白者，丹田有热，胸中有寒，邪在半表半里也。热入渐深则燥而涩，热聚于胃矣，宜
承气、白虎。若热病口干舌黑，乃肾水刑于心火，热益深而病笃矣。（然有苔黑属寒者，必
舌无芒刺，口有津液也、即小便之赤白，口中之润燥，舌苔之滑涩，亦皆因乎津液之荣枯，未足凭以遽断寒热
也，故尤宜以脉之有力无力细辨之。总之，医家治病，须随机应变，活泼泼地，不可胶执一方，不可泥滞一
药，不必以药治病，惟以药治脉可也。古今气运不同，旧方新病，何能符合，只可读其书，广其义，考其方，
得其理，潜心默究，自得其神，即罗氏譬之拆旧料而改新房，务必工稳耳。）
白苔是热聚丹田，寒留胸膈，湿气薰蒸所致。治宜燥湿和中。
滑白色者，邪未入腑，半表半里也，宜和解之。热入渐深，则燥而涩矣。
黄苔者，胃腑有邪热也，宜下之。
舌上有黑苔生芒刺者，其因有二∶非水来克火为寒极，即火极似水为热极，以
脉迟数无力有力辨之。一宜大承气，一宜理中汤。然十有九死之证也。
舌上黑苔生芒刺，刮不去易生者死。
舌卷囊缩，爪甲青黑，不知人事，面青作搐者，肝绝也。
二金散（出自《启玄》）
鸡内金、郁金，各取等份研成细粉。先用盐水汤清洗患处，然后将药粉吹入疮口。
打呵欠，是由于脾胃中气不足，以及精神过度劳倦所导致的。医经中说：足阳明胃经发生病变时，会出现战栗恶寒，喜欢伸展身体且频繁打呵欠的现象。“欠”这个动作，是阳气向上牵引，阴气向下牵引的结果，这是精气与神志不能相互依附，阴气与阳气不能相互守持的表现。
凡是各种舌部痈疽、疮疡和痹症，都汇总在这一部分中，以便于查阅和参考治疗。
舌头是心的外候，对应南方的火行。邪气在体表时，不会生成舌苔；邪气进入体内，津液与邪气搏结凝聚，就会生成舌苔并且显得滑润。舌苔发白的，说明丹田有热，胸中有寒，邪气处于半表半里的位置。如果热邪逐渐深入，舌苔会变得干燥涩滞，这是因为热邪聚集在胃腑，适宜使用承气汤或白虎汤治疗。如果是热病导致口干且舌苔发黑，这是肾水克制心火，热邪更加深重，病情危笃了。（然而也有舌苔发黑属于寒证的情况，必定是舌面上没有芒刺，口中津液充足。即使是小便颜色的赤白、口中的润燥、舌苔的滑涩，也都取决于津液的盛衰枯荣，不足以据此就匆忙断定是寒证还是热证，所以尤其应当仔细辨别脉象的有力与无力。总之，医生治病，必须随机应变，灵活机动，不可固执于某一方剂，不可拘泥于某一药物，不必单纯以药物去对抗疾病，而应以药物来调理脉象即可。古今的气运不同，旧有的方子与新发的疾病，怎么能完全符合呢？只能阅读医书，广博其义理，考证其方剂，掌握其道理，潜心默默探究，自然能领悟其中的神髓，就像罗氏比喻的那样，拆除旧料改建新房，务必做到工整稳妥罢了。）
白苔是热邪聚集在丹田，寒邪留滞在胸膈，湿气熏蒸所致。治疗宜用燥湿和中法。
舌苔滑而白色的，说明邪气尚未进入腑脏，仍在半表半里之间，适宜采用和解法。如果热邪逐渐深入，舌苔就会变得干燥涩滞。
黄苔，说明胃腑有邪热，适宜采用攻下法。
舌面上生有黑色舌苔并伴有芒刺的，原因有两个：要么是水克火导致的极寒证，要么是火极似水导致的极热证，通过辨别脉象的迟数、有力无力来区分。一种情况适宜用大承气汤，另一种情况适宜用理中汤。但这都是十个人里有九个会死亡的危重证候。
舌上黑苔生芒刺，刮不掉且容易再生的，预后不良，主死。
舌头卷缩，睾丸收缩，指甲青黑，神志不清，面色青紫且出现抽搐的，这是肝气绝的表现。
Erjin San (from *Qixuan*)
*Jineijin* (Gallbladder Membrane) and *Yujin* (Curcuma Longa Rhizome), in equal parts, are ground into fine powder. First, wash the affected area with salt water solution, then insufflate the powder onto the lesion.
Yawning is caused by deficiency of middle Qi in the spleen and stomach, as well as mental fatigue and overexertion. The Classics state: When the Foot-Yangming [Stomach] channel is disturbed, it causes aversion to cold with shivering, a desire to stretch, and frequent yawning. "Yawning" involves Yang drawing upward and Yin drawing downward; this indicates that Essence and Spirit fail to rely on each other, and Yin and Yang fail to guard each other.
All types of tongue carbuncles, sores, and bi-syndromes are compiled in this section for easy reference and treatment consultation.
The tongue is the sprout of the Heart, corresponding to the Fire element of the South. When pathogenic factors are at the exterior, no coating forms; when pathogens enter the interior, body fluids bind and coagulate, resulting in a coating that appears slippery. A white coating indicates heat in the Dantian [lower abdomen/kidney region] and cold in the chest, with pathogens located at the half-exterior/half-interior level. As heat penetrates deeper, the tongue becomes dry and rough due to heat accumulating in the Stomach; Chengqi Tang or Baihu Tang should be used. If a heat disease causes dry mouth and black tongue coating, it signifies Kidney Water suppressing Heart Fire, indicating profound heat and critical illness. (However, there are cases where black coating belongs to cold syndromes, characterized by the absence of prickles on the tongue and sufficient saliva in the mouth. Even variations in urine color, oral moisture, and coating slipperiness depend on the flourishing or withering of body fluids, and are insufficient grounds for hasty diagnosis of cold or heat. Therefore, one must carefully distinguish based on whether the pulse is forceful or weak. In summary, physicians treating diseases must adapt flexibly to changing circumstances, avoiding rigid adherence to specific formulas or herbs. One need not merely use drugs to treat diseases, but rather use drugs to regulate the pulse. Since the Qi and fortune of ancient times differ from those of today, how can old formulas perfectly match new diseases? One should only read the books, expand their meanings, examine the formulas, grasp their principles, and ponder them silently to naturally attain their spirit. As Luo described, it is like dismantling old materials to build a new house, ensuring stability and craftsmanship.)
A white coating results from heat gathering in the Dantian, cold lingering in the chest and diaphragm, and steaming dampness. Treatment should focus on drying dampness and harmonizing the middle.
A slippery white coating indicates that pathogens have not yet entered the Fu organs and remain at the half-exterior/half-interior level; reconciliation therapy is appropriate. As heat deepens, the coating becomes dry and rough.
A yellow coating indicates pathogenic heat in the Stomach Fu organ; purgation is appropriate.
Black coating with prickles on the tongue has two causes: either Water overcoming Fire leading to extreme cold, or extreme heat resembling Water. Differentiate using pulse characteristics (slow/rapid, forceful/weak). One condition requires Dachengqi Tang, while the other requires Lizhong Tang. These are critical conditions with a mortality rate of nine out of ten.
If black coating with prickles on the tongue cannot be scraped off and regenerates easily, death ensues.
Tongue retraction, testicular retraction, cyanotic nails, unconsciousness, blue complexion, and convulsions indicate Liver Qi exhaustion.
