我的表弟周克庵，字士变，精通医理。道光丙午年夏季，暑风病势猛烈，时疫广泛流行，患者大多伴有咽喉疼痛，死者接连不断，医生们都束手无策。周克庵家中患病的人很多，他亲自治疗使他们都痊愈了。他怜悯世俗医生见识浅薄，于是撰写了一篇论述说：暑风从口鼻侵入，时令的冷秽之气也从口鼻侵入，首先损伤上焦手太阴肺经。其初期表现的症状，有的咽喉疼痛且腐烂，有的不腐烂，身体洒洒然恶寒，体内蒸蒸发热，有汗但病不解，全身出现红晕，舌苔白腻。首选辛凉平剂，药物包括连翘、薄荷、荆芥穗、金银花、淡豆豉、牛蒡子、苦桔梗、杏仁、玄参、紫马勃、瓜蒌皮、白茅根、竹叶，可根据症状选用，以疏泄表风，兼宣化秽浊之气。
病情发展后，表现为但热不寒，咽喉疼痛仍在，痰涎稠厚腻滞，眼睛发红且眼屎多，舌质绛红无苔，红色痢疾中夹杂白色疹子，心烦口渴，神志昏闷，烦躁不安，睡眠中说胡话，醒来则神志清醒。症状类似犀角地黄汤证和白虎汤证，但不知道肺卫与心营距离很近，这是肺热侵逼心包络，并未完全进入营分，可以通过神志没有完全昏昧来辨别。此时如果贸然使用犀角，就是开门揖盗（引贼入室），或者如果识见蒙蔽、窍道阻塞，犀角配合牛黄清心丸、至宝丹，也不在禁忌之列。至于白虎汤证，脉象洪大，自汗不止，口渴无度，遵循古法诊脉确实无误；倘若用药不合法规，恐怕肺经的邪热没有出路，导致向下逼迫大肠而成为痢疾。适宜使用川郁金、黑山栀、瓜蒌皮、芦根、竹叶、桑叶、杭菊之类，以廓清热邪，开泄秽气。如果毒重者，甘草、人中黄、大青叶、板蓝根，也可以随意加入。再兼有的症状如有身体疼痛、肢体软弱，即暑风流窜于肢体，可参用防己、秦艽、桑枝一二味即可。总之，此证留恋在手太阴肺经居多，所以用药宜轻清宣解，不必使用苦寒沉降的药物，以免诛伐中下二焦无辜之地。
My cousin, Zhou Ken'an (courtesy name Shibian), was well-versed in medical principles. In the summer of Bingwu year during the Daoguang reign, the pathogenic factor of Summerheat-Wind (Shu Feng) was severe, and an epidemic broke out widely; most patients suffered from sore throat, with deaths following one after another. Physicians were at a loss, but Zhou Ken'an treated numerous cases within his family personally, achieving full recovery. Pitying the limited knowledge of contemporary physicians, he wrote an essay stating: Summerheat-Wind enters through the mouth and nose, as does the seasonal cold and turbid qi. Initially, it injures the Upper Jiao Hand-Taiyin Lung Meridian. The initial symptoms may include sore throat with or without ulceration, aversion to cold with shivering, internal steaming heat, sweating that does not resolve the condition, a diffuse red flush over the body, and a white, greasy tongue coating. The primary treatment should use a mild acrid-cool formula, selecting from Forsythiae Fructus (Lianqiao), Menthae Haplocalycis Herba (Bohe), Schizonepetae Spica (Jingjie Sui), Lonicerae Japonicae Flos (Yinjinhua), Fermented Soybean (Danshichidou), Armeniacae Semen Amarum (Xingren), Platycodonis Radix (Jiegeng), Bupleuri Radix (Chaihu - *Note: Text says Yuan Shen/Xuanshen*, corrected to Scrophulariae Radix (Xuanshen)), Phallus Impudicus (Zi Mabo), Trichosanthis Pericarpium (Gualou Pi), Imperatae Rhizoma (Baimaogen), and Bambusae Folium (Zhuye), chosen according to specific symptoms, to release the exterior wind and disseminate turbid qi.
In the subsequent stage, there is fever without chills, persistent sore throat, thick and sticky phlegm, red eyes with excessive discharge, a crimson tongue without coating, bloody dysentery mixed with white rashes, irritability, thirst, mental confusion, restlessness, muttering in sleep, but clear consciousness upon waking. These signs resemble those of Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) and Baihu Tang (White Tiger Decoction). However, one must recognize that the Lung Wei (Defensive) level is close to the Heart Ying (Nutritive) level; this is lung heat encroaching on the Pericardium, not yet fully entering the Ying level, which can be distinguished by the absence of deep coma. If Rhinoceros Horn (Xijiao) is used hastily at this stage, it is akin to "opening the door to invite thieves" (inviting pathogens deeper). Alternatively, if the mind is clouded and orifices are blocked, using Rhinoceros Horn combined with Niuhuang Qingxin Wan (Calculus Bovis Heart-Clearing Pill) or Zhibao Dan (Precious Treasure Pill) is not contraindicated. Regarding Baihu Tang syndrome, characterized by a flooding pulse, profuse spontaneous sweating, and extreme thirst, adhering to ancient methods of pulse diagnosis is indeed correct. However, if inappropriate herbs are used, the pathogenic heat in the Lung meridian may lack an exit route, forcing its way down to the Large Intestine and causing dysentery. It is advisable to use Curcumae Radix (Yujin), Gardeniae Fructus (Zhizi), Trichosanthis Pericarpium (Gualou Pi), Phragmitis Rhizoma (Lugen), Bambusae Folium (Zhuye), Mori Folium (Sangye), and Chrysanthemi Flos (Ju Hua) to clear heat and dissipate turbidity. For severe toxicity, Glycyrrhizae Radix et Rhizoma (Gancao), Indospongia (Renzhonghuang), Isatidis Radix (Daqingye), and Isatidis Radix (Banlangen) may be added as needed. If accompanied by body pain and limb weakness—indicating Summerheat-Wind wandering through the limbs—Stephaniae Tetrandrae Radix (Fangji), Gentianae Macrophyllae Radix (Qinjiao), and Mori Ramulus (Sangzhi) may be incorporated. In summary, this pathology mostly lingers in the Hand-Taiyin Lung Meridian; therefore, medications should be light, clear, and dispersing. One should avoid bitter-cold and sinking agents to prevent damaging the Middle and Lower Jiao unnecessarily.
