伤风鼻塞声重，头痛目疼，鼻流秽水，此风邪入
脑。宜用辛夷散加杏仁、桑皮、苦丁茶等味，清肺泄
热也。
肺悬上焦，气禀清肃，为五脏之长，相傅之官，治节出
焉。风为阳邪，性亦轻虚，专伤上焦。（内经）所谓清邪中
上也。盖邪既中上，必先入肺，肺被邪侵，则熏蒸化火，上
乘入脑，消烁脑脂，从鼻而下，化为秽涕，非徒清肺等药可
解者也。须藉辛夷、篙本、白芷、防风、升麻者，以轻浮上
升，而能搜剔风热也。更佐杏仁、桑皮以泻肺热，木通、苦
丁茶以利胃湿，则声可清而脑可撤也。
伤风咳不止;肋痛痰血，鼻息欠利，此热逼动
络。宜用苇茎汤合旋复花汤加苏子、地骨皮、枇杷叶
等味，降气和络也。
风寒入肺，久必化热!肺气不清，则鼻息欠利;热逼肺
络，则咳痰带血。此时不可以见血而遽头滋补，误延损祛之
途。最宜苇茎，地骨以清热，薏仁、蒌皮以润肺，苏子、旋
复花以降气，新绛，桃仁以和血，俾气血两清，而无过偏之
伤风咳剧欲呕，鼻不闻臭，此肺邪传胃。宜用泻
白散合小半夏汤加陈皮、茯苓、粳米等味，清肺和胃
也。
伤风虽解，遗邪未尽，必传于胃，故咳而欲呕，（内
经）所谓胃咳也。且鼻不闻臭，肺犹未清。故用桑皮、地
骨、杏仁清肺，半夏、茯苓、橘皮、生姜通胃，甘草、粳米
两和肺胃之阴也。
伤风导致鼻塞、声音沉重，头痛且眼睛疼痛，鼻腔流出浑浊液体，这是风邪侵入脑部。适宜使用辛夷散加入杏仁、桑白皮、苦丁茶等药物，以清泄肺热。
肺位于上焦，其气具有清肃的特性，是五脏之首，如同辅佐君主的宰相，治理节律的功能由此产生。风属于阳邪，性质轻扬虚浮，专门伤害上焦。《内经》所说的“清邪中上也”。既然邪气已经侵犯上部，必定先入肺，肺被邪气侵袭，就会熏蒸化火，向上乘袭进入脑部，消耗脑部的脂液，从鼻腔流出，化为浑浊的鼻涕，这不仅仅是清肺之类的药物所能解决的。必须借助辛夷、藁本、白芷、防风、升麻这些药性轻浮上升的药物，来搜剔风热。再辅以杏仁、桑白皮来泻肺热，木通、苦丁茶来利除胃中湿气，那么声音就可以清亮，脑部受邪的情况也可以解除。
伤风咳嗽不止，胁肋疼痛，痰中带血，呼吸不畅，这是热邪逼迫动及络脉所致。适宜使用苇茎汤合旋复花汤加入苏子、地骨皮、枇杷叶等药物，以降气和络。
风寒侵入肺部，时间久了必然化热；肺气不清爽，则呼吸不畅；热邪逼迫肺络，则咳嗽痰中带血。此时不能因为见血就急于进补，以免误入治疗虚损的路径。最适宜用苇茎、地骨皮来清热，薏苡仁、瓜蒌皮来润肺，苏子、旋复花来降气，新绛、桃仁来和血，使得气血两清，而没有过偏的弊端。
伤风咳嗽剧烈想要呕吐，鼻子闻不到气味，这是肺邪传至胃部。适宜使用泻白散合小半夏汤加入陈皮、茯苓、粳米等药物，以清肺和胃。
伤风虽然解除，但残留的邪气未尽，必定传至胃部，所以咳嗽且想要呕吐，《内经》所说的“胃咳”。而且鼻子闻不到气味，说明肺仍未清净。因此使用桑白皮、地骨皮、杏仁清肺，半夏、茯苓、橘皮、生姜通调胃气，甘草、粳米两者调和肺胃之阴。
Wind-cold (Shangfeng) causes nasal congestion and a heavy voice, headache and eye pain, with turbid discharge from the nose; this indicates wind pathogen invading the brain. It is appropriate to use Xinyi San (Magnolia Bud Powder) added with Xingren (Apricot Seed), Sangbai Pi (Morus Bark), and Kudingcha (Ilex Kudingcha Leaf), to clear the Lung and drain heat.
The Lung hangs in the Upper Jiao (Upper Burner), its Qi possesses a pure and descending nature, serving as the leader of the five Zang organs and the minister official, from which governance and regulation arise. Wind is a Yang pathogen, with a light and empty nature, specifically injuring the Upper Jiao. As stated in the *Neijing* (Inner Canon): "Clear pathogens attack the upper part." Since the pathogen has already attacked the upper region, it must first enter the Lung. Once the Lung is invaded by the pathogen, it steams and transforms into fire, ascending to invade the brain, consuming the brain's essence, and flowing down from the nose to become turbid mucus. This cannot be resolved merely by drugs that clear the Lung. One must rely on Xinyi (Magnolia Flower), Gaoben (Ligusticum Sinense Rhizome), Baizhi (Angelica Dahurica Root), Fangfeng (Saposhnikovia Root), and Shengma (Cimicifuga Rhizome) for their light and ascending properties to search out and eliminate wind-heat. Furthermore, assisting with Xingren (Apricot Seed) and Sangbai Pi (Morus Bark) to drain Lung heat, Mutong (Akebia Stem) and Kudingcha (Ilex Kudingcha Leaf) to promote urination and remove dampness from the Stomach, will clear the voice and resolve the condition in the brain.
In wind-cold, persistent coughing, hypochondriac pain, blood in sputum, and impaired breathing indicate that heat is forcing movement in the collaterals. It is appropriate to use Weisheng Tang (Reed Shoot Decoction) combined with Xuanfuhua Tang (Inula Flower Decoction) added with Suzi (Perilla Fruit), Digupi (Phellodendron Bark), and Pipaye (Loquat Leaf), to descend Qi and harmonize the collaterals.
When wind-cold enters the Lung, it eventually transforms into heat over time. If Lung Qi is not clear, breathing becomes impaired; if heat forces the Lung collaterals, coughing with bloody sputum occurs. At this time, one should not rush to tonify upon seeing blood, lest one mistakenly follow the path for treating consumptive diseases. It is most suitable to use Weisheng (Reed Shoot) and Digupi (Phellodendron Bark) to clear heat, Yiren (Coix Seed) and Gualou Pi (Trichosanthes Peel) to moisten the Lung, Suzi (Perilla Fruit) and Xuanfuhua (Inula Flower) to descend Qi, Xinjiang (New Crimson Dye/Safflower) and Taoren (Peach Kernel) to harmonize Blood, thereby clearing both Qi and Blood without excessive deviation.
Severe coughing in wind-cold accompanied by the desire to vomit, and loss of smell, indicates that Lung pathogen has transmitted to the Stomach. It is appropriate to use Xiebai San (White Herb Powder) combined with Xiao Banxia Tang (Minor Pinellia Decoction) added with Chenpi (Tangerine Peel), Fuling (Poria), and Jingmi (Rice Grain), to clear the Lung and harmonize the Stomach.
Although the wind-cold has resolved, residual pathogenic factors remain and inevitably transmit to the Stomach, causing coughing and the desire to vomit. This is what the *Neijing* refers to as "Stomach Cough." Moreover, the loss of smell indicates that the Lung is still not clear. Therefore, Sangbai Pi (Morus Bark), Digupi (Phellodendron Bark), and Xingren (Apricot Seed) are used to clear the Lung; Banxia (Pinellia Tuber), Fuling (Poria), Chenpi (Tangerine Peel), and Shengjiang (Fresh Ginger) are used to unblock the Stomach; and Gancao (Licorice Root) and Jingmi (Rice Grain) jointly harmonize the Yin of the Lung and Stomach.
