感，就是接触。冒，就是覆盖。接触了就必然会侵犯人体，侵犯了就会向内趋入；覆盖了就必然会蒙蔽，蒙蔽了就会导致内部瘀滞。当发生感冒时，病邪浅在于肌肤表层，通过发汗解表的方法就能使邪气消散，通过宣发透达的方法就能祛除病邪。这样病就好了，怎么会变得盘根错节、难以治疗呢？如果不尽早治疗，病邪就会由外向内传变，侵袭经脉和络脉，导致脏腑壅塞阻滞。病邪潜伏于骨骼，沦陷于骨髓，邪毒牢固地储存其中，演变成大病，难以迅速驱除，甚至达到危险的地步，直至死亡。这又是谁的过错呢？能不感到遗憾吗？
感冒的病邪，以风邪最先致病。风性行速，飘忽不定，吹拂人体。当风停止吹拂时，邪气便已进入身体。如果是风挟带寒邪，就称为风寒证，这是风与寒的结合，并非风与寒完全同等并重，所以不同于伤寒（六经辨证中的太阳伤寒），其脉象兼见浮紧，症状表现为气息急促、声音重浊。如果是风挟带热邪，就称为风热证，这是风与热的结合，并非风与热截然不同，所以不同于中热（中暑或热病），其脉象兼见浮数，症状表现为……（原文此处有缺字或通假，意指热象明显）。
感冒的根本原因，是由于卫气虚弱，玄府（汗孔）不闭合，腠理（皮肤纹理及间隙）经常疏松。虚邪贼风乘虚而入，首先损伤卫阳。因为肺主气，外合皮毛，所以风邪首先侵犯肺系。心火相合，肝风并至，邪气逐渐深入，因风势疾驰而传入体内。古籍方书中记载要避风如避箭，正常的风尚且如此，何况是戾气之风（疫疠之气）呢？
感冒的症状，不能一概拘泥于某种固定模式。头痛身热，轻症可能没有。但必定恶风恶寒，肢体不舒服，鼻子流清涕，呼吸堵塞且粗重，咳嗽气喘声音沉重，痰涎过多，咽喉干燥口闭，或者自汗湿透衣服。这些属于外感病因，应当用解表法去除。如果素来体内有痰热，像巢穴一样空虚积聚，病位主要在太阳经和阳明经。风邪容易进入，招引内邪而使其滋生。风借火势，火煽风枢，互相鼓动，导致病势盛于膈间。这属于内因致病，应当用调理疏通的方法（“爬梳”喻指梳理气机、化痰清热）。
治疗感冒，四季有所不同，不可违背。春夏季节宜用辛凉之剂，如升麻、柴胡、荆芥、防风、羌活、葛根等，能迅速见效。秋冬季节宜用辛温之剂，如桂枝、枳壳、人参、苏叶等，以及前胡、后胡、羌活、独活等，这是治疗的要点。对于内伤夹感的情况，宜用甘苦之品，与升散之法配合使用，如冲和汤、通圣散，取这两个方子作为代表。临证时要灵活变通，用心斟酌，这样才能治愈疾病，就像除草加锄头一样，所接触的邪气得以解决，所覆盖的病邪得以舒缓。
Gan (Infection/Contact) refers to touching or encountering. Mao (Covering/Overwhelming) refers to shrouding or enveloping. To encounter implies invasion; invasion leads to an inward tendency. To shroud implies obscuring; obscuring leads to internal stagnation. When a common cold occurs, the pathogen is superficial, residing in the skin and muscles. Releasing it through the exterior (diaphoresis) disperses it; promoting its exit eliminates it. Thus, the disease is cured. How could it become complicated and difficult to treat? If not treated early, the pathogen moves from the exterior to the interior, invading the meridians and collaterals, causing congestion and obstruction in the zang-fu organs. It may penetrate deep into the bones and marrow, where evil toxins accumulate firmly, transforming into severe diseases that are hard to dispel quickly, potentially leading to critical conditions or death. Whose fault is this? Can one not feel regret?
The pathogen of the common cold is primarily wind. Wind moves rapidly, unpredictably blowing upon the body. When the wind stops, the pathogen has already entered the body. If wind carries cold, it is termed Wind-Cold. This is a combination of wind and cold, not necessarily equal in severity, thus differing from Taiyang Cold Damage (Shanghan). The pulse is floating and tight, and symptoms include labored breathing and hoarse voice. If wind carries heat, it is termed Wind-Heat. This is a combination of wind and heat, distinct from Summerheat or Heat Stroke (Zhongre). The pulse is floating and rapid, and symptoms manifest as heat signs.
The root cause of the common cold lies in the deficiency of Defensive Qi (Wei Qi), failure of the Yuan Fu (pores) to close, and loose Cou Li (skin texture and interstices). Deficient evils and thieving winds invade, damaging the Defensive Yang first. Since the Lung governs Qi and controls the skin and hair, the wind pathogen attacks the Lung system first. Heart Fire may combine with it, and Liver Wind may join, allowing the pathogen to enter gradually, driven by the speed of wind. Ancient texts advise avoiding wind as if avoiding arrows; even normal wind is dangerous, let alone virulent winds (epidemic pathogens).
Symptoms of the common cold should not be rigidly fixed. Headache and fever may be absent in mild cases. However, aversion to wind and cold is inevitable, accompanied by limb discomfort, clear nasal discharge, nasal congestion with coarse breathing, cough and asthma with heavy sounds, excessive phlegm, dry throat, closed mouth, or spontaneous sweating soaking the clothes. These are external causes, requiring exterior-releasing treatment. If one previously harbors Phlegm-Heat, accumulating like a nest, the disease resides mainly in the Taiyang and Yangming meridians. Wind pathogen easily enters, attracting and nurturing internal pathogens. Wind fuels fire, and fire fans the wind pivot, mutually agitating, causing the disease to flourish in the diaphragm area. This is an internal cause, requiring regulation and dredging (clearing phlegm and heat).
Treatment of the common cold varies by season and must not be ignored. In spring and summer, acrid-cool herbs such as Shengma (Cimicifugae Rhizoma), Chaihu (Bupleuri Radix), Jingjie (Schizonepetae Herba), Fangfeng (Saposhnikoviae Radix), Qianghuo (Notopterygii Rhizoma et Radix), and Ge Gen (Puerariae Lobatae Radix) are used for quick effect. In autumn and winter, acrid-warm herbs such as Guizhi (Cinnamomi Ramulus), Zhike (Aurantii Fructus), Renshen (Ginseng Radix et Rhizoma), and Suye (Perillae Folium), along with Qianhu (Peucedani Radix), Houpo (Magnoliae Officinalis Cortex - *Note: Text says Er Hu, likely referring to Qian/Hou or similar pairs, but context suggests aromatic/dispersing herbs*), Qianghuo (Notopterygii Rhizoma et Radix), and Duhuo (Angelicae Pubescentis Radix) are key. For internal involvement mixed with external contraction, sweet-bitter herbs are used in conjunction with ascending and dispersing methods, such as Chonghe Tang (Harmonizing Decoction) and Tongsheng San (Free and Easy Powder). One must adapt flexibly according to circumstances, using wisdom to guide treatment, so that the disease is cured like weeding with a hoe, resolving what was encountered and relieving what was shrouded.
