《黄帝内经》说：受到风邪侵袭，人体上部首先受病。又说：虚邪贼风（乘虚而入的异常气候），阳分部位首先受病。又说：如果保持身心清净，肌肉腠理就会闭合坚固以抵御外邪，即使有大风和剧烈的毒邪，也不能伤害人体。大概风是天地间浩荡流动的气，四季八节风向的变化，从未停止过。偶尔有人被风邪所伤，是因为不能遵循清静养生的法则，导致腠理不固密、体表阳气虚弱，这是第一个原因。有的人兼有虚痰和热邪，气机拂逆郁结，风邪容易从外部束缚肌表，这是第二个原因。有的人火邪侵犯肺金，煎熬津液形成痰浊，痰火奔涌上逆，风邪自然从体内产生，这是第三个原因。感受风邪致病，没有超出这三种情况的。脉象浮而大的属于风邪，浮而缓的属于伤风鼻塞，浮滑而大的属于内热生风。治疗方法：对于表虚受风者，专门适宜使用发散法，不要导致出汗过多而亡失阳气。如果有汗出且表邪未解，应当实表散邪，以桂枝汤为主方，可加入桂枝、白芍等药。如果是内夹痰热又感受风邪者，可用参苏饮之类的方剂。如果是痰壅火盛、内热生风者，用防风通圣散（方剂见中风章节）之类加减调理。凡是鼻塞声重，头脑胀痛头痛，鼻流清涕，怕风，属于寒证；鼻中流出浊涕且热气不时冒出，咽喉干燥咳嗽，痰唾稠粘，属于热证。外有风邪需要疏散，内有痰火尚未平息，可用黄芩、黄连、枳壳、桔梗，以及二陈汤（方剂见痰饮章节）之类清肺降火，利气消痰。
主方（治疗头疼鼻塞）：苍术、藁本、羌活、白芷、川芎、防风（各七分），细辛、甘草（炙）。各五分。上方加生姜三片，葱头三个，用水煎煮。
如果有汗且表邪未解，加桂枝、白芍；如果没有汗且怕风，加紫苏、葛根。
参苏饮：治疗伤风感冒，发热头痛，咳嗽鼻涕稠厚。功效为疏解邪气、清气、消痰、除热。
组成：人参、紫苏叶、葛根、半夏、前胡、桔梗、陈皮、茯苓、枳壳（等分），木香、甘草（减半用量）。上方加生姜、大枣，用水煎服。如果咳嗽，去掉人参、木香，加桑白皮、杏仁；如果肺热，加黄芩。
川芎茶调散：治疗伤风，邪气上攻头目，鼻塞声重。
组成：薄荷叶（四两），川芎、荆芥（各二两），羌活、白芷、防风、甘草（各一两），细辛（五钱）。
将上述药物研为细末，每次服用二钱，饭后用茶汤调服。
The *Yellow Emperor's Inner Classic* states: "When injured by wind, the upper part of the body is affected first." It also states: "Deficient evil and thieving wind (abnormal climatic factors that invade when the body's resistance is low) affect the Yang aspect first." Furthermore, it states: "If one maintains purity and stillness, the flesh and pores will close and resist; even with great wind and severe toxins, they cannot cause harm." Wind is the vast and dynamic Qi of heaven and earth. The changes of the eight winds across the four seasons are constant. Occasionally, people are injured by wind because they fail to follow the Dao of purity and stillness, resulting in insecure pores and deficiency of superficial Yang; this is the first cause. Some individuals have concurrent deficiency-phlegm and heat, causing Qi to be stagnant and depressed, making it easy for wind-evil to bind from the exterior; this is the second cause. In some cases, fire invades Lung Metal, scorching body fluids into phlegm; with phlegm-fire surging upward, wind naturally arises from within; this is the third cause. Contracting wind-disease does not exceed these three causes. A pulse that is floating and large indicates wind; floating and moderate indicates wind-injury with nasal congestion; floating, slippery, and large indicates internal heat generating wind. Treatment methods: For those with superficial deficiency contracting wind, dispersing methods are specifically appropriate, avoiding excessive sweating that leads to the loss of Yang. If there is sweating and the exterior pathogen remains, the exterior should be secured while dispersing the pathogen; Guizhi Tang (Cinnamon Twig Decoction) is the main formula, with additions such as Cinnamon Twig and White Peony Root. For those with internal phlegm-heat combined with wind-evil, Shen Su Yin (Ginseng and Perilla Leaf Decoction) or similar formulas are used. For those with phlegm obstruction and abundant fire, where internal heat generates wind, Fangfeng Tongsheng San (Saposhnikovia Decoction for Unblocking the Intestines and Stomach) or similar formulas are modified for regulation. Generally, nasal congestion with heavy voice, head distension and headache, clear nasal discharge, and aversion to wind belong to Cold syndrome; turbid nasal discharge with intermittent hot air, dry throat with cough, and thick sticky sputum belong to Heat syndrome. When external wind-evil needs dispersing and internal phlegm-fire is not yet resolved, Scutellariae Radix (Huangqin), Scutellariae Barbatae Radix (Huanglian), Aurantii Fructus Immaturus (Zhike), Platycodonis Radix (Jiegeng), and Erchen Tang (Two-Cured Decoction) or similar formulas are used to clear the lungs, descend fire, promote Qi movement, and eliminate phlegm.
Main Formula (for headache and nasal congestion): Cangzhu (Atractylodis Rhizoma), Bencao (Ligustici Wallichii Rhizoma), Qianghuo (Notopterygii Rhizoma et Radix), Baizhi (Angelicae Dahuricae Radix), Chuanxiong (Chuanxiong Rhizoma), Fangfeng (Saposhnikoviae Radix) (each 0.7 fen); Xixin (Asari Radix et Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma, prepared) (each 0.5 fen). Add three slices of fresh ginger and three green onion heads to the above, decoct in water.
If there is sweating and exterior pathogen, add Guizhi (Cinnamomi Ramulus) and Baishao (Paeoniae Radix Alba); if there is no sweating and aversion to wind, add Zisu (Perillae Folium) and Gegen (Puerariae Lobatae Radix).
Shen Su Yin: Treats wind-injury and common cold, fever, headache, cough, and thick nasal discharge. Actions: Dispel pathogenic factors, clear Qi, eliminate phlegm, and remove heat.
Ingredients: Renshen (Ginseng Radix et Rhizoma), Zisuye (Perillae Folium), Gegen (Puerariae Lobatae Radix), Banxia (Pinelliae Rhizoma), Qianhu (Peucedani Radix), Jiegeng (Platycodonis Radix), Chenpi (Citri Reticulatae Pericarpium), Fuling (Poria), Zhike (Aurantii Fructus Immaturus) (equal parts); Muxiang (Aucklandiae Radix), Gancao (Glycyrrhizae Radix et Rhizoma) (half dose). Add fresh ginger and jujube to the above, decoct in water and take orally. If coughing, remove Renshen and Muxiang, add Sangbaipi (Mori Cortex) and Xingren (Armeniacae Semen Amarum); if lung heat, add Huangqin (Scutellariae Radix).
Chuanxiong Chatiao San: Treats wind-injury, pathogenic factors attacking the head and eyes, nasal congestion, and heavy voice.
Ingredients: Boheye (Menthae Haplocalycis Herba) (4 liang), Chuanxiong (Chuanxiong Rhizoma), Jingjie (Schizonepetae Spica) (each 2 liang); Qianghuo (Notopterygii Rhizoma et Radix), Baizhi (Angelicae Dahuricae Radix), Fangfeng (Saposhnikoviae Radix), Gancao (Glycyrrhizae Radix et Rhizoma) (each 1 liang); Xixin (Asari Radix et Rhizoma) (5 qian).
Grind the above into powder. Take 2 qian per dose, mixed with tea soup after meals.
